A natural disaster is an event that can cause great damage and loss of life and property in the region where it occurs. After disasters, the incidence of infectious diseases and the rate of infection in people increase. Infection formation is generally affected by post-disaster public living spaces, leading to situations such as inability to maintain social distance, difficulties in accessing clean water and food, infrastructure problems, and interruptions in basic health services. The causes of epidemics may vary depending on the type of disaster experienced.

Epidemic diseases may increase due to fecal-oral diseases caused by contaminated water and food, as well as droplet, respiratory and contact infections caused by social housing and crowded environments. Since all these diseases may be difficult to control in the event of an epidemic, having an effective surveillance system will be important in controlling and managing the epidemic. After a disaster, a rapid risk assessment should be made, and priority should be given to re-establishing primary prevention measures and rapid implementation of control measures. In this section, disasters, infectious diseases that occur after disasters, management, reporting and reporting of infectious diseases, and measures to protect against infectious diseases that may occur after natural disasters will be discussed.
