ABSTRACT
Historical records evidenced of urban landscape changes, and environmental transitions brought
by the improper growths and urban development’s of the urbanisation and industrialization in the
developing countries, especially in India, significantly chaotic urban sprawl and industrial growths,
and the development of its allied activities for the recent decades, invites new, emerging, reemerging, and triggers the tropical infectious diseases including vector borne diseases (VBD) as
well non-communicable diseases. Urban sprawl has a multiplier effect of growth of unplanned a
crowded housing, and industrialization has an impact on the urban landscape with commercial and
market development, and roads over large expanses of urban land while little concern for
appropriate urban planning. The union government of India is launching to promote 100 mega
smart city projects / metropolitan / urban agglomeration across the nation for betterment of the
standard of living infrastructure facilities by 2030. The large scale urban landscape architectural

the heart of the urban landscape, and its fringe areas on the consequence of built-up structures,
construction of roads transport networks, drainages, commercial buildings, human dwellings,
educational buildings, legal and medical health services, income tax professionals, small scale to
large scale industries, etc., The census of India, reports highlighted that people mass movements /
migration from rural to the urban, and small towns to mega cities are notably accelerating trends
for the recent decades mainly for the purposes of occupation, education, trade and commerce, and
professional services, generally reasons for male migration, and marriage is the absolute reason
for female adults migration. The spatial and temporal aspects of malaria and dengue has been
declining trends in rural settings, however, it has been accelerating trends in the urban settings due
to the urban buoyant migrants. Urbanization and industrialization effect on urban landscape
environment leads to breakdown of sanitations, water-borne diseases associated with inadequate
and unsafe drinking water supply, tendency to use metal, plastic, and mud pots water storage
containers, discarded domestic waste misshapen to vector breeding habitats containers, urban
heat island, garbage waste disposal, liquid waste from dwellings, and industries, air pollution (dust,
pollen and spores suspended as particles, Sulphur Dioxide-SO2, nitrogen oxides-NO, CarbonateCO3, depletion of Oxygen O2, Ozone-O3, Methane Gas- CH₄, Lead- Pb, Mercury- Hg etc.,),
exonerated by the industries and urban transport emissions, modern transport / shipping goods
and services, and collectively hazard to human health through erratic infectious diseases and
vector borne diseases immediately.

The united nations reports 2021, shows that
approximately, 500 international airports are
operating airline transport services across the
globe, about, 5million people, i.e. 2.8 million
people are travelling within the nations and
2million people are travelling to other nations
every day with an average increase of 5% airbus passengers in a year, since 1990, as a
result, can spread infectious disease across the
globe within an hour. These major three
components are stimulating new infection or
increase
of
communicable
diseases.
Communicable diseases mainly caused by
bacteria, fungus, pathogen, virus, and transmit
through
vectors,
and
non-communicable
diseases (mental health, cancer, diabetics,
Historically, the occurrences of new, emerging,
re-emerging tropical infectious and noncommunicable diseases have been influenced on
the consequences of spatial and temporal
dynamics of urbanisation, industrialisation, and
globalizations, mainly, in the developing nations.
Remarkably, in india, rapid changes in the urban

socio-economic
changes influenced by industrialization, and
globalisation of the modern technology.
Landscape architectural changes by the
influences of high raised buildings, transport

bus stands, markets, railway networks,
recreational centres, amusements, and it parks,
increase of tertiary activities / professional
services, educational institutions, legal services,
markets, trade & commerce, health and medical
services. However, on the other hand, it has
brought out the human ill health and socioeconomic imbalance, and has highly influenced
the people's society. Human ill health diseases
are classified into; i) communicable / infectious
diseases, and ii) non-communicable diseases,
are being caused by parasites, vectors,
pathogens, virus, bacteria, fungus, protozoa, and
helminths, are persistent with the long term
ecological, climate and landscape changes
(Fig.1). These processes are mainly due to the

most common in the urban or semi urban
agglomeration of the developing nations [1-4],
approximately, 2 million people die every year
because of the unsafe drinking water supplies,
and 90 % of those who die from diarrheal
diseases, predominantly, young children below
15 years [1,3]. In India, researchers emphasised
the spatial autocorrelation associated with
variables, viz; the dense population settlements /
or slums, lack of drainage facilities, inadequate

Evidenced from throughout the historical records,
rapid urbanisation in the developing nations has
a multiplier effect on the urban landscape
environmental transitions, particularly, unplanned
built-up
structures,
slum
development,
sanitations breakdown, insufficient water/ lack of
safe drinking water supply, forest clearing for
urban dwelling, and road network constructions,
absences of drainage facilities, unacceptable
solid waste disposal grounds, increase of air
pollutions, are all collectively fuelled to persuade
on underpinning to communicable and noncommunicable diseases (Fig.3). Worldwide, 884
million people do not have access to an
adequate domestic and safe drinking water
supply, and about 3 times that number lack basic

urbanization and increase of commerce and
trade markets bringing major job opportunities to
the skilled, semi-skilled, and unskilled workers,
economic
infrastructural
developments,
educational institutes. On the other hand, it has
been challenging health issues, predominantly,
people who migrates from Bihar, Jharkhand,
Odisha, Chhattisgarh, and Madhya Pradesh,
Uttar Pradesh, and West Bengal [18] are carrying
Plasmodium vivax, and Plasmodium falciparum
malaria parasites during the mass movements to
Kolkata (West Bengal) for living, and hence,
major metropolitan floating population in West
Bengal, considered as potential hot spot hosts
for malarial parasites in the state, Despite, the
municipality authority of Kolkata has operated
department to setup a public health clinic and
entomological division to vector mosquito control
towards the urban malaria parasite transmission
control through Anopheles stephensi genus
mosquitoes urban malaria vector control, the
disease has been persisting in Kolkata, and has
become challenging health issue in the
corporation area in the state. Whereas, 40 % of
the urban dwellers and migrants who have been
living in the metropolitan, are having positive with
infectious diseases, viz; tuberculosis, human
immunodeficiency

deficiency syndrome (AIDS), sexually transmitted
virus (STD), cancer, cardiovascular disease

discarded containers in the peripherals, [9-14].
The spatial extension of dengue spreads in the
newer regions in the Europe, Asia, Middle Asia,
North America, mainly because of the climate
change caused by increase of air pollution from
the industrial and transport emission, and
globalisation
of
trade
and
commerce,
development of tourism industries, increase of
tourists / international travellers cross the borders
with asymptomatic signs in the recent years
[15,16]. In India, the effect of rapid development
of urban agglomeration had been brought the
crowded unplanned settlements with a complex
of risk factors simultaneously [11,12,], and
causing huge magnitude of tropical infectious
diseases as well as non-communicable diseases
recorded from the socially, and economically
vulnerable poor community in the crowded urban
environments, and has been affected at higher
degree and has challenge to the local heath
authority, and the national sustainable health
promotions .
Spatially, a significant association was exited
between population movements and infectious
disease transmission [17]. The mass movement
of people interstate urban migration has been a
greater extent from Bihar, Uttar Pradesh,
Jharkhand, and Assam. These major urban
migration has been arisen to Mumbai
metropolitan (Maharashtra) pursued by New
Delhi, Kolkata (West Bengal), Chennai (Tamil
Nadu),

major migration from Uttar Pradesh, Jharkhand,
Haryana, Uttarakhand, Himachal Pradesh,
Jammu & Kashmir to Chandigarh, New Delhi,
and Mumbai, during 1972-1982 (Fig.2a-2c), and
then it has been gradually reduced till 2002, and
subsequently stabilized. Migration, whether
within the state, interstate, within the country, or
cross the nations (international level), has forever

(Punjab), Jaipur (Rajasthan), Raipur (Madhya
Pradesh), Hyderabad (Telangana), Bhopal
(Madhya Pradesh), and Gurgaon (Haryana) are
facing the analogous community health issues,
mainly due to a less significant of socioeconomic conditions, low education level, and
lack awareness among the people who has been
moving over the period from rural to the urban
permanently, whereas, in Noida (Uttar Pradesh),
comparatively environmental health issues are
under control, because it is emerged as a well
planned urban landscape architecture, integrated
multidisciplinary approach, and modern industrial
city.

2.1 Industrialization and Health Issues
have access to safe drinking water / an adequate
water supply for domestic purposes. A recent
study has revealed that the spatial association
between mining activities and cholera outbreaks,
mostly affected in the age group of < 15 years
young children and the senior citizens > 60
years, p-value <0.05, and >40 % of the infected
patients were migrated from other places as host
and has fuelled by breakdown of sanitation [20],
it is a serious public health problem in 42
developing nations [21,22]. In India, Cholera is
most possibly associated with breakdown of
sanitation, poverty, and lack of clean drinking
water supply in the clustered settlements in the
mining activities, and industrial estates [15,18,2325].
In India, large scale and allied small scale
industrial developments were accelerated for the
past 7 decades, and attracted occupation,
throughout the historical records, people mass
movements for their living from rural to the urban
and small town to metropolitans, or new towns
near to industrial estates. On the other hand,
public health diseases created by the industrial
pollution (liquid, solid, and air pollution), has
increased both in the spatial and temporal
aspects. Industrial pollution causes lung
breathing difficulties, and cardiovascular disease,
stroke, lung cancer, chronic obstructive
pulmonary
diseases,
diarrheal,
and
gastrointestinal diseases, meningeal, skin
infections,
tuberculosis,
and
respiratory
infections. Approximately, 2.4 million people
have died due to air pollution, and 90 % of the
urban residents in India breaths lower than the
global standard of Air quality, and approximately,
2million casualty in a year due to unsafe drinking
water supplies, and 1.5million people do not
have basic sanitation services lead to diarrheal
/dysentery diseases, as a result, 90 % of the
children mortality, particularly, in the developing
nations, including India. According to the United
Nations 2018, about 900 million people do not
Cardiovascular diseases (Acute myocardial
infarction (AMI), stroke, and atrial fibrillation (AF)
are associated with similar geographical patterns
caused by Development of CVD is associated
with behavioural risk factors, such as; impetuous
lifestyle changes and health care behaviour with
smoking, unhealthy diet, obesity and physical
inactivity [26]. In India, about 63% of total deaths
have been recorded due to non-communicable
diseases, of which 27% deaths have been
recorded due to cardiovascular disease, mainly
in the middle age group of 40-69. Throughout

the past records, sexually transmitted infections
(STD), zoonotic diseases, bacterial infections,
viral fever, and vector borne diseases are high in
the urban settings associated with urban and
industrial developments. In India, the spatial
distribution pattern of STD, HIV/AIDS are highly
associated with metropolitans, industrial estates,
distribution of goods and truck / lorry transport
services, and trade and market networks, and
the increase of production demand on mobile
phone networks among the urban settings [27].
The adult prevalence of HIV/AIDS was identified
in Chennai city in Tamil Nadu, and the burden of
whole state is 7% of the nation, over the period
of 2 decades, and the spatial-temporal trends of
the infection found constant in the western
districts where the industrial growth, trade and
commerce, urban agglomerations are growing
rapidly and steadily [28]. The overcrowded urban
agglomeration due to the huge population
movements towards the industrial growth and
development sites have been brought the

and affects blood vessels in the bottom of legs
and feet, destruction of nerve tissues, and
secondhand smoke affects the pregnant women
and unborn baby [30], and spraying toxic
chemicals for pesticides resulted stillbirth (a
typical example, Kasaragod district in Kerala)
[30,31]. In India, huge records of neurological
disorders, deformed limbs and still birth was
recorded in the Kasaragod district of North
Kerala due to ground water pollution by the
Endosulfan pesticide widely used for agricultural
crops, including cashew, tea plantation, fruits
orchards, and extensive paddy field in the upper
basin for more than 2 decades [31]. It has also
affected and vanished many of the animals,
birds, and insects’ biodiversity, in Kerala [31].
West Bengal, Jharkhand, Bihar, Uttar Pradesh,
Assam, Manipur and Chhattisgarh are reported
to be most affected by arsenic contamination of
groundwater above the permissible level. Recent
clinical evidence indicates that significant
association between drinking contaminated water
and diabetes, hypertension, reproductive turmoil,
hyperkeratosis,
gastrointestinal
symptoms,
disturbances of cardiovascular disease, and
nervous system disorders, and in due course
leads to serious or mortality. In survivors, bone
marrow depression, haemolysis, hepatomegaly,
melanosis, polyneuropathy, encephalopathy, and
pigmentation are recorded, as well as emerging
evidence of significant health concerns. In India,
the states of Kerala, West Bengal, Jharkhand,
Bihar, Uttar Pradesh, Odisha, Assam, Manipur,
Madhya Pradesh, and Chhattisgarh are reported
with high arsenic contamination of groundwater
above the permissible level 5µg/litre. The
implementation of rain water harvesting, check
dam constructions, watershed management, and
mega water resource projects could be reducing
the arsenic level for ensuring the permissible
water quality.
2.2 Arsenic
Arsenic is caused by both nature and man-made;
nature (volcano, forest fire, folds, faults,
landslides, earthquake, heavy rain and floods),
and
man-made
(anthropogenic
activitiesindustrial pollution, urban waste effluents,
intensive and extensive herbicides, agriculture
and medical entomological pesticides, smoke
emission from coal thermal power plants, etc.,), it
is affecting mainly in the landscape soil
topography, and groundwater. The arsenic
effects are mostly caused by anthropogenic
activities, and lead to the human standard of
living environmental conditions deteriorated.
Habitual contaminated drinking water causes
2.3 Globalisation and Health Issues
Speedy travels by the development of aircraft
technology reducing travel time for making the
global networks, and has marvellous effect on
fashion of trade and commerce, particularly, in
the developing nations, simultaneously, it has
impact on challenging accelerating infectious
diseases [24,32,33]. Evidenced of that the
exploitation, obliteration of the local /native
culture, change in pressure on socio-economics,
and especially, modify the native culture fetched
through the globalisation of past foods culture,

growing multiple level during past 20 years, and
the accounted annual migration growth was
double the world annual population growth of
1.2% [34]. The infectious diseases claim huge
deaths in the developing world, particularly in the
age group of children below the age of 5years
[14,35-37]. Economic developments has been

nations through the course of industrialisation,

unfortunately, anti-social and anti-national
elements are making ways to bioterrorism is the
deliberate release of viruses, bacteria, toxins, or
other agents to cause illness or death in people,
animals, or plants, and diffuse passing through
contaminated food materials, ruined water, or air
(for a typical example, bioterrorism became a
reality occurrence when letters containing
powdered Bacillusanthracis, the U.S. Postal
Service was used to spread this bacterium
spores in October 2001, similarly, the botulinum

preserved readymade foods, persevered fruits,
vegetables, animal meats, eggs, shellfish
(aquatic invertebrates animal foods-crustaceans,
molluscs, and echinoderms), and processed
foods and groceries. Fresh fruits and vegetables
become infected if they are washed with water
contaminated or irrigated in the field adding
animal manure or human sewage in the farming
land. Raw foods of animal origin are the most
likely to be contaminated, raw meat and poultry,
raw
eggs,
unpasteurized
milk,
poultry,
unpasteurized milk, and raw shellfish are causing
Salmonella bacteria, and Calicivirus [33]. New,
emerging, and re-emerging infectious diseases
have been brought all the way through the
contamination of foods during harvesting,
processing, storage, and transport, and engross
long times before it reaches cities in the inlands
as well overseas international markets (for typical
example, a fungus Cryptococcus gattii emerged
as new infectious disease among the human and
animals in the Vancouver Island, British
Columbia province, Canada, during 1999), the
fungus, which causes harmful infections of the
lung and brain, is causing a spreading epidemic
infections and somewhat, ultimate deaths, it has
spread to the spatial extend of Pacific NorthWestern United States of America(USA), and it
had previously been known only in the tropical
and / or subtropical climatic regions of the Africa,
Australia, Southeast Asia, and the South Pacific
[33]. The fungus might have been introduced
through the import of contaminated trees, shoes,
wooden pallets / shipping crates [33]. Similarly,
during 1999, mosquito-borne infection-West Nile
virus-suddenly began targeting New York
dwellers, it was a new experience, and before
that it had had been restricted to the spatial
spread in Africa, West Asia, and the Middle East
Asia, currently, the infection caused by West Nile
virus has spread in North America, and Latin
America, and the appearance of Legionnaires
disease/ pneumonia , toxic shock syndrome [33],
and HIV/AIDS during the mid1970s and early
1980s, HIV/AIDS, and the spatial extent of
tuberculosis [1,51], respiratory and emerging
intestinal infections, intestinal worms, Chagas,
Pneumonia, diarrhoea, dengue, malaria, West
Nile virus, and Lyme disease, and SARS virus

mainly
through
the
extensive
continental travellers including tourists, sports
personals, researchers /scientists, and business
executives who are from distinctive geographical
regions, different immunisation, and host for
many infectious diseases, and also disease

3. VECTOR BORNE DISEASES
Malaria, Chikungunya, Dengue, Japanese
encephalitis, Zika Virus, Nipah virus, Kala-azar,
Lymphatic filariasis, Scrub Typhus fever,
Kyasanur Forest Disease, Schistosomiasis, Fleaborne (murine) typhus (caused by a bacteria
called Rickettsia typhi), West Nile virus, yellow
fever, and Lyme disease are most common
vector borne diseases [3,35] in the developing
and the third world nations. Globalization is
making way for vector borne diseases spread in
the newer regions, and vectors and infected
asymptomatic patients are migrated within the
nation or crossing the international border
through flights, cargo ships, as well goods and
services, parcels, trade and commerce
[16,33,36,41]. The vectors, namely; mosquitoes,
fleas, mites, ticks, rats, snails, sand flies, and
dogs are transmitting vector borne diseases [3].
The global incidence of dengue has been
increased 30 - 40 % every year, especially, for
the past two decades about 45% of the people
living in the 142 countries estimated
approximately 450 million people at risk of
infection, and 500,000 cases of severe dengue
or dengue haemorrhagic fever (DHF) with 25,000
deaths
annually
reported
worldwide,
approximately, half the world’s population is
currently infected with a vector-borne disease

Control [43,45,47] authority has made health
plan to eliminate malaria by 2050, however, the
trend of urban malaria is persistently reported
over the space and time, and the problem is
challenging issues to the public health
programmers due to the floating migrant people
who are living in the urban [45], the national
malaria surveillance system shows the declining
trend of malaria in the rural settings, but it has
been accelerated trends in the urban settings,
particularly, in the developing nations [40,43,45] .
[3,16,42-44,].The first epidemic cases of dengue
was reported in Afghanistan during 2019, and16
Nations many of the developing and low income
countries have experienced with increase of
dengue epidemic records during the year 2020,
namely, Bangladesh, Brazil, Cook Islands,
Ecuador, India, Indonesia, Maldives, Malaysia,
Mauritania, Mayotte (France), Nepal, Philippines,
Singapore, Sri Lanka, Sudan, Thailand, TimorLeste and Yemen, and Vietnam. The spatial
extents of dengue epidemic cases are
geographically extended to the new areas in
Europe during the recent years. Climatic factors,
and land use/ land cover categories are playing
important role in the increase or decrease of
vector mosquitoes as well as VBD epidemics
[3,13,16,41-45]. In India, the both geographical
and historical sequential aspects of vector borne
disease epidemics have increasingly been
reported across the nation for several decades,
and it has been found generally everywhere
across the nation, however, the frequency of
outbreaks in urban settlements province has
clustered and accelerated trends relatively higher
than rural settings, similarly, it has been occurred
in the global nations perhaps boosted by the
transitory
migrants
who

3.1 Global Pandemic Disease
Impacts, and Mitigation
Risks,
Pandemic diseases are huge epidemics at the
large scale geographical regions, and it has been
extended to the neighbouring regions, or the
entire nation, or the whole world [3,24,33]. The
epidemics of Diarrhoeal disease, Cholera,
Tuberculosis, Avian influenza, Yellow fever,
Ebola, Plague, Meningitis, MERS, Influenza,
West Nile Fever, Zika virus, Rift Valley Fever,
Lassa fever, Leptospirosis, HIV/ AIDS, Malaria,
dengue, Hepatitis-B, and Covid-19 are the major
pandemic diseases [37,38,48,49,51,]. People
mass movements at the international / intercontinental level has responsible for large scale
spread of diverse infectious diseases, including
STD, HIV/AIDS, malaria, dengue, Influenza, etc.,
has effect on the infertility, a serious long term
reproductive health consequences including still
birth, newborn mortality, etc., than the
instantaneous impact of the disease. 1.4 million
People who have died with Tuberculosis (TB)
infection in 2019, among those 0.2 million have
co-infection of HIV/AIDS [3,36,51]. Tuberculosis
is alone responsible for the huge deaths in the
world top 10 infectious diseases. Approximately,
10 million people have been infected with
tuberculosis (TB) across the globe, and have 5.6
million men, 3.2 million women and 1.2 million
children, and estimated 95% of deaths have
occurred in the developing countries [1,3].
Diarrhoeal diseases / Dysentery / Cholera
disease caused huge deaths [3,22], and followed
by TB, second leading cause of deaths, and
followed by diarrhoea kills around 525, 000
children below five years and above 70 years old
in every year, it claims highest mortality in SubSaharan Africa and South Asia. Malaria is the
third serious burden of mosquito vector borne
infectious disease, it has been recorded 229
million cases worldwide, and deaths doll is 409
000 during 2019 [3]. In India, 162.5 million
people (i.e. about 12% of the total population of
India, 2021) affected with malaria, particularly
The combined effect of feeding plant nutrient with
blood meal has impact on the results of the
boosting longest survivals >30 days, and highest
fecundity rate was obtained in the Aedes aegypti
dengue vector mosquitoes (p-value < 0.001) [46].
As the result shows that wherever the vegetation
land covers thickly great quantities in and around
the human living areas, support the aegypti
vector mosquito’s profusion, and thus, dengue,
chikungunya, and zika virus fever transmission
may perhaps have occurred decidedly high. It
means that the rural setting has high risk of
dengue epidemics than the urban setting. In
contradiction to this statements, throughout the
historical records in the global nations, dengue
epidemics was highly recorded in the
metropolitan region than the rural settings,
because
of
the
urban
environmental
determinants together with large quantity of
discarded manmade containers and limited
vegetation land cover supports Aedes genus
mosquitoes fecundity and density [42-45,47].
Malaria is a serious disease transmitted by
malaria parasites (P. vivax, P. falciparum, P.
Malariae, and P.ovale) into the human body by
the
infected
female
Anopheles
genus
mosquitoes. In India, it has been drastically
reduced and the National Vector Borne Disease

cinema theatres, temples, shopping malls,
hotels, migrations (inter-districts, interstate, and
or outside the country), exports and imports,
public transports, family and community functions
with limited people, social distance, making
awareness to wearing N95 WHO standard face
masks, prohibited public gathering, etc., at
present, the pandemic situation is under control,
however, the researchers are giving alarming to
the world nations for the third wave of SARSCoV-2 / Covid-19 delta variants, therefore,
Covid-19 vaccinations double dose, and personal
protective health care measures as per the WHO
guidelines/ICMR Government of India guidelines
could be saved from the yet another dangerous
pandemics in India [37,49, 50].
North Eastern and Eastern India, it is highest
record of the South East Asia regions, at the
same time, and it has showed a reduction of
malaria cases 49% in 2020 [16,45].
Since November 2019, Covid-19 virus infectious
disease and its variants has paralyzed the whole
world, and destroyed the total economic
conditions [48,49]. In India, accumulated infected
cases of 32.6 million reported with Covid-19
(Coronavirus disease), death recorded 0.436
million during the last years (Oct-2019-Aug2021), and Maharashtra is the most affected
state, and followed by Kerala, Karnataka, Tamil
Nadu, Andhra Pradesh, Uttar Pradesh, West
Bengal, Delhi, Chhattisgarh, Odisha, and
remaining states are recorded below 1 million
cases. In the world, the cumulative record of 214
million infected cases with death recorded 4.46
million as on 25th August 2021 [48,49]. Covid-19
virus / coronavirus (2019-nCoV) spread through
a Virus laboratory in the Wuhan State in ChinaDuring Nov 2019, and a deadly disease rapidly
diffuse to Italy in Europe, and immediately to
North America, Asia, Africa, South America,
Australia, Middle Asia, Caribbean and Pacific
Islands, and within a short span of period Covid19 virus pandemic extended throughout the
globe [49]. Literature source evidenced that
coronavirus (2019-nCoV) virus has become a
community transmission across the global
nations. The first wave of pandemics has lesser
effect than the second wave of coronavirus
(2019-nCoV), because, metamorphosis of the
Covid-19 virus variants into 3 types, viz., these
Covid-19/ SARS-CoV-2 infection is a meticulous
pneumonia causing severe damage to cardiac
damage, and the geographical distribution of the
Covid-19 variants has been attributed with the
specific spatial patterns [48,49]. There are a
complex of phenomenon responsible for the wild
spread of pandemics and unexpected huge
mortality, among that chiefly, genetically modified
SARS-CoV-2 infection, and In India, the second
wave of infections are modified Delta variants of
COVID-19 strain, and it was spread like wild fire
across the nations and claimed huge deaths due
to overcrowded floating population movements
from urban to rural, and the people have not
been exposed to these virus and variants
previously, as a result, immunity among the
community absolutely zero, however, the
government of India has made appreciate right
decision to control the pandemic situation
through the complete lockdown including the
educational institutions, trade and commerce,
markets, recreations and amusement parks,
3.2
Medical Waste and Health Care
Delivery Services
The improper waste disposal of medical waste,
such
as;
syringes,
soiled
dressings,
damaged/removed human body parts, diagnostic
test samples, contaminated blood, used chemical
waste, expired / tainted pharmaceuticals,
discarded medical devices, and toxic /radioactive
materials leads to ill health / infection to health
care workers, medical waste cleaners and waste
handlers, and thus, probably risk of infection to
the entire community who are living in and
around the waste disposal. About 34,000 HIV
infections, 1.7 million hepatitis-B, and 315 000
hepatitis-C infections were recorded due to the
unsafe injections reported in 2010, therefore,
WHO has provided the guidelines to safe
management of medical wastes, which includes
waste minimization and recycling, waste
handling,
classification,
consignment
and
transportation, and organize to treatment and
disposal alternatives, and training [50]. In India,
The Ministry of Health and Family Welfare, Union
Government of India, has various health plans to
organizing the health infrastructures, deploying
the health personnel, managing the epidemic
situation, and given much more attention for
health care delivery services to the weaker
section and the people who are living in the
remote locality, highly vulnerable socio-economic
weaker groups in the urban migrants/ the urban
poor, tribes, and minority groups. A map based
environmental
health
and
the
spatial
epidemiological approaches for assessing the
probability of risk of infectious and non-infectious
diseases, conserve the spatial relationships
between the each of its mechanism [52], and
based on the final map products the health
officials and programmers could deliver health

care services to all and render justice a head

4. CONCLUSION
The infectious and non-communicable diseases
are most probably associated with urbanisation,
industrial developments, and globalisation.
Remote Sensing and GIS have been used for
mapping
multiple
diseases
including
communicable and Non-communicable diseases
for the recent decades. The thematic mapping of
diseases provides insights to identifying the
spatial and temporal patterns for a long period. A
clear illustration of the disease at a glance may
perhaps provide a better understanding of
disease ecology, and risk factors, insights of the
infections as well as facilitate targeted towards
control,
health
information,
management,
prevention and allocation of health care
resources. Mapping the multiple infectious
diseases and non-communicable illness could
provide a way lead to better understanding of the
spatial patterns of disease epidemics over
a time periods, similarities and dissimilarities of
the one or multiple diseases could be
revealed disease-specific determinants, and
public health programme managers joint
hands
with
multidisciplinary
experts
enable plan for prevention and control in
advance.
