No matter what Gabriel Garcia Marquez says, there's no love in the time of cholera, a deadly diarrhea spread by contaminated water. In the wake of the earthquake that devastated Port-au-Prince, a cholera outbreak raged across Haiti. About 8,400 Haitians have died of cholera since 2010, reports NPR, and 1,000 are still dying each year.
"Part of the reason we think the outbreak grew so quickly was the Haitian population had no immunity to cholera," Tufts University environmental engineer Daniele Lantagne told NPR. "Something like when the Europeans brought smallpox to the Americas."
Tuberculosis killed some of history's greats including Franz Kafka, George Orwell, Eleanor Roosevelt and Henry David Thoreau. The disease seemed to be on its way out after vaccines and a sequence of antibiotics were found to combat the disease. Unfortunately, drug-resistant strains developed in the 1980s and then spread. Tuberculosis is now globally the second largest killer after HIV/AIDS, when considering single infectious agents, according to the World Health Organization. In 2010, 1.4 million people died from tuberculosis.
