Authorities investigating the deaths of at least 60 people in northwestern Congo suspect the water source in one of the areas may have been contaminated, the World Health Organization said Friday. But the agency said it's too early for any definitive conclusion.
Doctors are investigating more than 1,000 illnesses that emerged since late January in five villages in Congo's Equateur province, where high rates of malaria have complicated efforts to diagnose the cases and where officials have said they've been unable so far to confirm the main cause.
