2012 was marked by
infectious disease outbreaks across the country, and West Nile
virus and Hantavirus were of top concern for health officials.
Reuters.com, weather conditions contributed to the worst
outbreak of West Nile virus since 2003 and an unusual outbreak of
Hantavirus in Yosemite National
Park killed three of the infected 10 visitors.
CDC and state officials have said that rainfall in the spring
and extreme summer heat contributed to the severity of the West
Nile virus outbreak by affecting mosquito
populations. As of December 11, 5,387 cases of West Nile virus had
been reported in 48 states, resulting in 243 deaths, the CDC said
in its final 2012 update on the outbreak.
