I've been hearing a lot about the H1N1 virus. What's the deal?

The H1N1 virus is a type of influenza virus that has been around for quite some time, but it wasn’t until recently that scientists realized how dangerous it could be. In 2009, a new strain of H1N1 was discovered in Mexico and spread rapidly across the world, infecting millions of people. It caused a pandemic, which means it spread quickly and widely throughout the population. This strain of H1N1 was especially deadly, as it had a higher mortality rate than other types of flu viruses.
