nfluenza viruses spread in tiny droplets caused by coughing and sneezing. They usually spread from person to person. Sometimes, however, people become infected by touching something that was recently contaminated with the virus and then touching their mouth or nose.

The flu attacks the lungs, nose, and throat. Young children, older adults, pregnant women, and people with chronic disease or weak immune systems are at high risk.

Symptoms include fever, chills, muscle aches, cough, congestion, runny nose, headaches, and fatigue
