Historically, the United States has seen its share of epidemics. There are others, however, that continue to be a thorn in the side of our population in spite of having some of the best doctors and technology on the planet.

A total of 9,421 tuberculosis cases were reported in 2014. Norovirus, Salmonella, and Listeria cause hundreds of deaths and thousands of hospitalizations each year, many of which can be avoided through proper food preparation. The CDC estimates that from the 1976-1977 season to the 2006-2007 flu season, flu-associated deaths ranged from a low of about 3,000 to a high of about 49,000 people. One of the most prevalent? Approximately 50,000 people are infected with HIV each year. Since the first cases were reported in the early '80s, over 25 million have died worldwide.

Here, we've compiled some of the biggest that have wreaked havoc on U.S. soil over the last 200-plus years.
