In the upcoming months NCOH will be hosting a series of scientific lectures on COVID-19, with a special focus on the One Health approach to current challenges. The first webinar “COVID-19 in minks” took place on 6 July, World Zoonoses Day. If you missed it, below you can find access to the full webinar recording and the presentation slides. The next NCOH-webinar will be on 3 September, registration is open. You can register here.
On 26th of April a Dutch mink farm tested positive on COVID-19. By 13th July 2020, 23 mink farms were found to be positive. The outbreaks in mink farms are a zoonotic spillover event from human to animals. This provided scientists with a unique opportunity to study how the virus jumps between species and spreads through the mink populations. The infected mink farms could potentially become a viral reservoir and may cause new outbreaks in humans. Hence, it was decided to cull all mink on infected farms. Overall conclusions about the SARS-CoV-2 infection in mink farms:
- Covid-19 severity in mink farms varies from mild to severe
- Introduction was most likely through humans, although this is unknown for some farms
- Virus sequences show clusters of relationships between several infected farms
- Mink-to-mink and mink-to-cat transmission detected within farms
- Proof was found for occupational exposure to SARS-Cov-2 RNA (viability unknown)
- At least two farm workers were infected by mink
- Risk of environmental exposure outside infected farms are thought to be negligible
