EcoHealth reframing
of disease monitoring
Decade-old (1) and recent warnings for
coronaviruses with zoonotic epidemic
potential (2) could have prevented the
emergence of coronavirus disease 2019
(COVID-19) (3). We therefore agree with
Watsa and colleagues (“Rigorous wildlife
disease surveillance,” Perspective, 10 July,
p. 145) that wildlife biosurveillance should
increase. However, representing animals
as a threat to humans through disease
transmission leads to ill-conceived reactive policies (4). A perspective (5) in which
animals and humans share similar risks of
pathogens and infections, making animals
relevant disease models and sentinels,
would be more effective. Clarifying the connection between animal and human health
could increase public support for research
seeking to understand host-switching in
animals, such as the study of virus evolution
(6), interactions in pathogen communities
(7), and pathogen discovery (8).
A shared-risk perspective on emerging infectious diseases mirrors the field
of EcoHealth, which explores the links
between ecosystem, animal, and human
health. Such strategies place value in
healthy ecosystems through an integrative
approach that considers both pathogen
biodiversity and social-ecological drivers
(9). Prevention based on understanding
the transmission of pathogens through
EcoHealth-based emerging infectious
disease surveillance is a promising avenue
for sustainability science, orders of magnitude cheaper than mitigation in response
to a transfer to human hosts (10), and less
intrusive than current crisis responses.

Disease transmission can occur at live animal markets, but zoonotic disease research could benefit from an emphasis on humans’ and animals’ shared risk of infection.

Response
We agree with Vanhove et al. that wildlife
conservation and emerging infectious
disease screening are two sides of the
same coin. Wildlife and humans can
be vulnerable to spillover events by the
same pathogen. For example, respiratory
diseases (1) and Ebola virus (2) outbreaks
have occurred simultaneously in great
apes and humans. Pathogens also affect
biogeographical species range expansions, contractions, and extinctions (3).
Biosurveillance efforts should reflect that
health risks are shared by humans and
wildlife, a central tenet of the One Health
framework (4). As Vanhove et al. point
out, wildlife can serve as the source for
preventive solutions that mitigate spillover risks into humans and animals.
A shared risk perspective could also
combat the narratives that portray animals
as dangerous pests or disposable commodities that endanger human health (5), as
in the case of bats (6), many of which are
likely not hosts for coronaviruses such as
severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (7). In addition to
emphasizing shared risk, such misinformation can be countered with well-researched
messaging following a zoonotic outbreak.
Conservation social science has honed a
suite of tools to identify the often unpredictable human motivations behind (8),
and the possible negative consequences of,
such communications (9).
Colella et al. suggest that surveillance
efforts should include natural history collections. Some natural history museums
and zoos archive biobanked specimens,
cryopreserved viable cell cultures, disease
specimen banks, and histopathology
samples, but this highly effective practice
(10) is limited by high costs. We agree
that devoting funding toward biodiversity banking within countries at high
risk for emerging infectious diseases
would improve conservation outcomes.
Taxonomically diverse biobanked tissues
and live cell cultures could expand studies
of host-pathogen relationships, clarifying host range or affected tissues and
providing in vitro systems for infectivity
and pathogenicity investigations. Such
collections could allow drug development for humans to expand beyond just
a few animal laboratory models, given
that relatively well-studied viruses such
as SARS-CoV-2 are potentially broadly
infectious across taxonomic orders (11).
Comparative genomics and transcriptomics among nonmodel species are
used infrequently in biomedical research
programs but hold great potential for
prioritizing species and gene targets with
alternative host defense mechanisms for
laboratory study (12).

across currently siloed efforts in zoonotic research and mitigation. To achieve
comprehensive decentralized pathogen
surveillance, there is an urgent need to
develop environmental and biodiversity
infrastructure in biodiverse countries
experiencing high rates of habitat
conversion, wildlife trafficking, and
human-wildlife interactions.
Approximately one-third of One
Health networks lack an environmental
component, fewer than half are active
in wildlife surveillance, and almost
none is led by developing countries (1).
International support for development
of natural history museums with frozen
vertebrate tissue collections remains a
key component missing from the One
Health equation. Most pathogens causing
severe outbreaks in humans are zoonotic
in origin (2); thus, understanding their
evolution and that of their wild animal
hosts is imperative.
As was the case for coronavirus disease
2019 (COVID-19) (3), identifying wild
animal reservoirs can be challenging
when biorepositories are lacking (4). In
most countries, natural history biorepositories remain poorly supported and
largely disconnected from public health
initiatives. For example, most studies of
bat coronaviruses to date (5), including
the PREDICT animal surveys discussed
in Watsa et al., did not preserve host
specimens or tissues, thus limiting the
potential for molecular host identification
or replication and extension of the science
(6). Emerging infectious disease response
hinges on sampling depth across space,
time, and taxonomy, the very sampling
enabled by museum biorepositories.
As primary biological infrastructure,
in-country development of museum collections that follow best practices (7), with
specimen data freely available through
the internet, should be an international imperative (8) for effective global
surveillance and mitigation of emerging
infectious diseases.
