The virus caused about 284,400 deaths worldwide3. It’s now one of the seasonal flu strains. Getting vaccinated is key to preventing it3.
How Does H1N1 Spread?
H1N1 spreads through tiny droplets in the air. An infected person can pass it on by coughing, sneezing, or talking. The virus travels to others nearby.
