A six month-long measles outbreak in Madagascar has infected more than 68,000 people and killed an estimated 900, according to World Health Organization figures cited Thursday by The Washington Post. The WHO has confirmed 553 deaths, and 373 more are expected. A WHO spokesman told the Post that a major part of the problem is a low vaccination rate on the island: WHO and UNICEF reportedly estimate that less than 60 percent of people are vaccinated against the disease. The nation has launched a mass surveillance and vaccination campaign to try and contain the epidemic.
