Argentina

Argentina is mass-vaccinating people against yellow fever amid concern its first deadly outbreak of the disease in 42 years may spread from jungle areas to cities. The mosquito-borne virus killed a farm worker last week in a rural area of Misiones province, which borders Paraguay and Brazil, nine months after a tobacco worker died in the same area, the country's first confirmed yellow fever fatality since 1966. At least 2.5 million Argentineans risk exposure to the virus, said Misiones Governor Maurice Fabian Closs in a statement on the provincial health authority's Web site. (Bloomberg)
