International health organizations are increasing their efforts to control outbreaks of cholera and measles among displaced people in war-torn Liberia.
The World Health Organization (WHO) is chlorinating water in Liberia's capital, Monrovia, to stem a cholera epidemic. The WHO says it will purify the city's 5,000 water wells every four days.
In the counties of Gbarpolu and Lofa, the U.N. Children's Fund is conducting an emergency immunization campaign against an outbreak of measles. Aid workers hope to vaccinate 42,000 children over the next week.
In Monrovia, clean water, food and medicine have been scarce since hundreds of thousands of displaced civilians streamed into the capital during the fighting that preceded an August peace deal.
