Evidence of Climate Connections to the Return of Infectious Diseases

• Outbreaks of malaria, eastern equine encephalitis (NE U.S.), waterborne disease outbreaks, i.e., typhoid, Hepatitis A, bacillary dysentery (Chile and Peru), and new appearances of harmful algal blooms (Asia and North America) are correlated with El Nino events. Further, cholera appears to be similarly associated with El Nino events (Bangladesh and South America).

• Research Reports have linked a 1°C increase in the average temperature in Rwanda in 1987 to a 337% rise in the incidence of malaria in that year.
