The 2019-2020 flu season is underway for most of the country, however some parts of the country are still seeing lower levels of
flu activity.
Activity is being caused mostly by influenza B/Victoria viruses, which is unusual for this time of year. H1N1 viruses are the next most
common, followed by H3N2 viruses, which are decreasing in proportion.
The flu season is just getting started; elevated flu activity is expected to continue for weeks. Its not too late to get vaccinated.
Flu vaccination is the best way to reduce the risk from flu and its potentially serious complications.
