The cyclone affected some 1.2 million people in the country, 750,000 in Zambézia according to the United Nations reports. On 16 March, local authorities declared an outbreak of cholera in Zambézia, when some 350 new cases were reported within 24 hours.
In addition to the destruction and displacement, Freddy contributed to an increasing number of cholera cases in Zambézia because it destroyed water infrastructure. A total of 123 health facilities were also destroyed, posing additional constraints in access to healthcare in the province.
Cholera is caused by a water-borne bacterial infection of the intestine, and is transmitted through contaminated food or water, or through contact with fecal matter or vomit from infected people. Cholera can cause severe diarrhoea and vomiting, and rapidly prove fatal, within hours, if untreated.
Within second half of March, the Ministry of Health reported around 8,000 cumulative cases of cholera in Zambézia, from which 3,100 had been admitted in health facilities. Dozens of deaths have also been reported due to cholera.
