How can the virus mutate into one that can be passed from human to human?
Viruses are notorious shape-shifters, able to constantly rearrange their genes and swap genetic material with different strains. Virologists are watching carefully for evidence that the microbe has begun swapping genetic material with a human virus — that’s when it could turn deadly for people. One worrisome sign: This summer there were reports out of Indonesia that the virus was found in pigs, which often act as incubators for human infections.
