Aerial View the Destruction from Cyclone Idai in Mozambique

Mozambique is recovering from Cyclone Idai, which made landfall March 22. The storm brought massive flooding and resulted in 446 deaths in the country thus far.

Cyclone-ravaged Mozambique faces a "second disaster" from cholera and other diseases, officials have warned, as the United Nations launched an urgent aid appeal for an estimated 1.8 million people affected by storm winds and flash floods.

Speaking to reporters on Tuesday, Antonio Guterres, the UN secretary-general, described Cyclone Idai which slammed into Mozambique, Zimbabwe and Malawi on March 14 as "one of the worst weather-related catastrophes in the history of Africa".
