(CNN) New footage from inside several hospitals in Yemen reveals the crisis facing the war-torn country as it battles to contain one of the world's worst ever outbreaks of cholera.

The videos, provided to CNN by the International Rescue Committee, show children being treated for possible symptoms of the infectious disease in hospitals and mobile health units in the city of Aden and other areas in southern Yemen in late August.

A ravaged health care system, devastated infrastructure and near famine -- the results of a bloody civil war that began in March 2015 -- have all contributed to the spread of what the World Health Organization has described as "the worst cholera outbreak in the world."

The United Nations has counted 777,229 suspected cases as of October 2, many of them in children. As of September 13, there were 2,074 known deaths from cholera across the country, according to the WHO, with previous reports estimating that 5,000 people were being infected each day.

Mohammed Alawi Hadi, 6, and his brother Salih Alawi Hadi, 3, are treated for cholera at a hospital in Aden.

Sabah Abdullah Salim, whose 2-year-old son, Mohammed, has cholera, sought help from an IRC mobile hospital in Al Buraiqeh.
