Viruses closely related to the deadly MERS coronavirus are lurking in bats and one group, known as HKU5, may be just one mutation away from making the jump to humans. A new study reveals how these ...
A phylogenetic tree of SARS-CoV-2 sequences, built with Nextstrain, displays sequences colored by their clade and organized by collection date. Over time, sequences mutate and diverge, forming new ...
