Every year, some people get infected by a flu virus. The strains tend to vary from year to year. The 2017-2018 flu season was especially nasty and dangerous.
The Centers for Disease Control and Prevention (CDC) state that the single best way to prevent seasonal flu is to get vaccinated each year. Good habits like covering your cough and washing your hands often can help stop the spread of germs and prevent respiratory illnesses like the flu. There also are flu antiviral drugs that can be used to treat and prevent flu.
