Machine learning may lead to better flu vaccines

A team led by scientists at UGA's Odum School of Ecology has developed an algorithm that can accurately predict how a seasonal flu virus is expected to evolve. Such information may allow seasonal flu vaccines to be updated ...

The next pandemic? How a familiar virus exploits new hosts

Planet Earth—a mere speck in our universe—is home to more viruses than there are stars in the cosmos. They exist at life's outer limit, performing a delicate dance that has lasted eons but can turn in an instant. Not ...

Orthomyxoviridae

Influenzavirus A Influenzavirus B Influenzavirus C Isavirus Thogotovirus

The Orthomyxoviridae (orthos, Greek for "straight"; myxa, Greek for "mucus") are a family of RNA viruses that includes five genera: Influenzavirus A, Influenzavirus B, Influenzavirus C, Isavirus and Thogotovirus. The first three genera contain viruses that cause influenza in vertebrates, including birds (see also avian influenza), humans, and other mammals. Isaviruses infect salmon; thogotoviruses infect vertebrates and invertebrates, such as mosquitoes and sea lice.

The three genera of Influenzavirus, which are identified by antigenic differences in their nucleoprotein and matrix protein infect vertebrates as follows:
