Type A has two different subtypes or strains, based on the chemical structure of the virus. The H1N1 swine flu virus is a type A influenza virus. Type B is not divided into subtypes. Both type A and type B are responsible for the seasonal influenza outbreaks. Outbreaks occur more ...
Learn about influenza (flu) symptoms, treatment with antiviral drugs, flu shot side effects, and prevention during flu season. Discover when to get the flu vaccine, how long the flu lasts, the contagious period, flu types, and how it spreads.

We assumed real-time RT-qPCR cycle threshold (Ct) values were indicators of quantitative virus shedding and used symptom diaries to create a score that tracked influenza-like illness (ILI) symptoms (fever, cough, or sore throat). We fit phenomenological nonlinear mixed-effects models stratified ...
Some scientists now consider the disease to be “endemic,” a virus that appears to be here to stay, like influenza. That’s why experts continue to recommend staying on top of your booster shots, which, like the annual flu shot, are reformulated on the regular to target evolving strains ...
