New Bat Virus Sparks COVID Concerns

Scientists have discovered a bat virus that is closely related to COVID-19 and can infect both bats and humans. The virus, called BANAL-236, was found to be able to replicate in human cells, but not in normal bat cells, and was able to evade the human immune system's response to infection. This is a key finding because it suggests that the virus was able to jump from bats to humans, a process known as zoonotic spillover, and that it has developed ways to avoid being detected by the human immune system. The study provides new insights into how COVID-19 and other similar viruses are able to spread from animals to humans.
