Although tuberculosis (TB) is preventable and curable, it is the second-biggest infectious disease killer behind HIV and claims nearly 1.3 million lives each year.

A cholera epidemic is rapidly spreading along the Congo River in western Democratic Republic of Congo.

More than 250 people had died as a result of the disease by July 21, and the epidemic is expected to soon reach the country's crowded capital, Kinshasa.
