Two types of influenza viruses are responsible for seasonal flu outbreaks: Influenza A and B. Influenza A accounts for around 75 percent of all cases and tends to cause more severe illness in adults.

Influenza B viruses, however, only circulate in humans. They are divided into just two lineages that cause seasonal outbreaks, Dr. Lowen said.
