**3. Overview of Cyclone Idai**

Due to the damages caused by Cyclone Idai, it is important to know that different humanitarian helps were given, coming from national and international entities, both to the outbreak of cholera and to other diseases, in order to reduce the impact caused to the cyclone victims.

The central region of Mozambique was affected by heavy rains since 6 March 2019. It was a system formed in the Mozambican channel, which evolved from tropical depression to moderate tropical storm called Idai that took more than 800 lives and displaced thousands of individuals [17].

The house's destruction, roads, hospitals, clean water, and sanitary facilities also puts the traveler's health at risk, so they should always take the basic prevention, such as drinking and using safe water, washing hands often with soap, avoiding bug bites and direct contact with contaminated floodwater, or avoiding travels to dangerous areas [18, 19].

Idai was one of the worst tropical cyclones on record to affect Africa and the southern hemisphere and caused catastrophic flooding, landslides, and large numbers of causalities in Mozambique, Zimbabwe, and Malawi, affecting more than 3 million people, but the most affected area was Beira, Mozambique's second largest port city, where the cyclone's landfall was on 14 March [17]. The heavy rains, strong winds, and severe flooding caused problems with water and food supplies, sanitation, electricity, transportation, shelter, communication, security, medical care, and mosquito control, creating opportunities for outbreak diseases, such as cholera. Due to the disasters caused by Idai, 6766 cholera and 43,556 malaria cases were registered [1, 19–21].

Idai affected 1,85M people (more than half were children), displacing 90,000 to 136 accommodation sites, mostly schools and churches. The sheltered people were sleeping in open spaces, increasing the risks of gender-based violence [11].

Tropical Cyclone Idai was outside the range expectations for a typical tropical cyclone that has happened in Mozambique and its neighboring countries. More than 14 countries provided supplies to help the affected areas. The United Nation's Central Emergency Response Fund (CERF) launched an emergency appeal for US \$282 million to respond to cyclone, which affected Mozambique, Malawi, and Zimbabwe. Furthermore, goods and military or rescue planes, helicopters, ships, and boats were provided to aid the huge search and rescue effort needed. Only 17% of the total amount required had been funded [3, 10, 22].
