    Summary:
    A new study confirms that pangolins confiscated from the illegal
    wildlife trade in Viet Nam host SARS-CoV-2 related coronaviruses.



    FULL STORY ==========================================================================
    A new study in the journal Frontiers in Public Health led by scientists
    from the Wildlife Conservation Society (WCS) confirms that pangolins confiscated from the illegal wildlife trade in Viet Nam host SARS-CoV-2
    related coronaviruses. Previously, only pangolins confiscated in China
    had tested positive for SARS-CoV-2 related coronaviruses.


    ==========================================================================
    The authors of the study say that the findings are further evidence that
    the transnational nature of the wildlife trade can facilitate coronavirus
    and other viral transmission and amplification along the trade chain,
    providing further evidence that pandemic and epidemic prevention must
    also be focused on pathogen spillover from wildlife.

    The study detected SARS-CoV-2 related coronaviruses, circulating in
    Sunda pangolins (Manis javanica) confiscated from the illegal wildlife
    trade in Viet Nam. Analysis revealed that the coronaviruses identified
    in these pangolins were closely related to coronaviruses previously
    detected in pangolins confiscated from the illegal wildlife trade in
    Yunnan and Guangxi provinces, China.

    Said the study's lead author, Nguyen Thi Thanh Nga of WCS's Viet Nam
    Program: "We know that SARS-like coronaviruses (SARS-CoV-2 and SARS-CoV-1)
    can cause serious disease in humans. This study confirms the presence
    of coronaviruses in the SARS-CoV family in trafficked pangolins in
    Viet Nam. Eliminating the trade in pangolins and other wild mammals
    and birds will eliminate this high-risk pathway for viral spillover and pathogen emergence." All eight species of pangolins have been listed
    on CITES Appendix I since 2017, prohibiting all international trade for commercial purposes. All four species of Asian pangolins, including the
    Sunda and Chinese pangolin (Manis pentadactyla) are considered Endangered
    or Critically Endangered across their geographic range.

    The authors of the study tested specimens from a total of 246 pangolins
    from wildlife confiscation events that occurred in Viet Nam in the years
    2016 to 2018. Specimens collected from seven individual pangolins in
    2018 tested positive for a SARS-CoV-2 related coronavirus.

    In addition to testing pangolins for SARS-CoV-2 related coronaviruses,
    the authors reviewed media reports of pangolin trafficking cases involving
    Viet Nam between 2016 and 2020. Multiple pangolin confiscation events
    sampled in this study in Viet Nam involved other live wildlife including a
    mix of non-human primates, reptiles, and birds. These observations support long-held concerns that the live wildlife trade, moving wild animals
    out of their natural habitats and into human dominated landscapes and
    large urban centers, poses a serious and increasing risk of initiating epidemics from emergent pathogens in human populations.

    These findings support current recommendations on regulation of live
    wildlife trade and markets, including the April 2021 Interim Guidance
    on 'Reducing public health risks associated with the sale of live wild
    animals of mammalian species in traditional food markets' issued by the
    WHO, United Nations Environmental Programme (UNEP), and the International Organisation for Animal Health (OIE), which called on governments to
    "Suspend the trade in live caught wild animals of mammalian species for
    food or breeding purposes and close sections of food markets selling
    live caught wild animals of mammalian species as an emergency measure
    unless demonstrable effective regulations and adequate risk assessments
    are in place." The authors also indicate that current international recommendations are too narrowly focused on open markets and do not
    address the much longer wildlife supply chains, trade of both legally
    and illegally sourced wildlife from its source. The authors indicate
    the need for wildlife trade policy reform to curb the risks of future
    pandemics and say mitigation measures must consider that the wildlife
    trade spillover interface contains novel viruses, which are not detected
    with current sample screening practices or procedures.

    Among countries, China has initiated a multi-sectoral and sustained
    crackdown on illegal wildlife trade and legislative reforms designed
    to completely phase out the farming/sourcing, trade, and consumption
    of terrestrial wildlife as food. Viet Nam banned the importation of
    wildlife in January 2020, as an immediate response to the identification
    of SARS-CoV-2 in China, and called for its own heightened enforcement
    of existing laws on illegal wildlife trade as stipulated in the July
    2020 Vietnamese Government Prime Minister's Directive No. 29 on "urgent solutions to manage wildlife." In the past two years, the Government
    of Viet Nam has revised a number of decrees addressing animal health,
    public health, food safety, and wildlife management with the aim of
    mitigating the risks and impacts of future pandemics. These include Decree
    14 on regulating penalties for administrative offenses involving animal husbandry and Decree 07 issued in early 2022 which increased sanctions
    for violating wildlife trade laws and regulations.

    WCS worked closely with local partners in Viet Nam to carry out this
    research.
