South Florida meningitis outbreak baffles health experts

State and national health experts are baffled as to how a rare and deadly strain of meningitis killed four people and infected eight others in South Florida since December, an unprecedented outbreak in the United States. The cases of the W135 strain of meningitis were disclosed by Miami-Dade health officials. They were recommending vaccinations for those in high-risk groups, mainly those living in close and crowded situations such as college dorms or military barracks.
