White-tailed deer susceptible to SARS-CoV-2 infection, study finds

Rss Feed - Fri, 01/15/2021 - 23:20
A team of scientists recently demonstrated that white-tailed deer are highly susceptible to SARS-CoV-2 infection. Moreover, the infected animals are capable of transmitting the virus to their non-infected counterparts via indirect contact.

Image-based deep learning haplotype-guided study maps the global adaptation of SARS-CoV-2

Rss Feed - Fri, 01/15/2021 - 21:53
A new study used deep learning with image recognition technology to trace the emergence of variants with increased viral fitness. Higher fitness leads to rapid expansion of these lineages in the areas where they are introduced. This type of study could facilitate the development of more effective antibodies and vaccines to help contain the pandemic.
