diseases due to poor sanitation, inadequate water supply and poor monitoring and detection. At the same time, floods have had a direct impact on the epidemiological pattern of malaria in Ethiopia because they create many breeding grounds for mosquitoes. Health Impacts on Ethiopians The onslaught of floods poses a serious threat to the health of Ethiopians. Examples include direct deaths, injuries, infectious diseases, non-communicable diseases, psychosocial health and malnutrition. Short-term Impact: Bacterial Growth During floods, the state of the environment is altered after heavy precipitation, for example, temperature, humidity and surface vegetation. These changes may favor the growth of pathogens. As a result, pathogens may spread rapidly through contaminated water. As well as because of the difficulty of access to clean water already clean sanitation facilities clean water and improved sanitation, the rate of disease transmission increases again. Acute Watery Diarrhea & Malaria The problem of acute watery diarrhea after the floods was exacerbated by the dense population, destruction of water facilities, and limited sanitation. In times of flooding, people may be forced to drink non-clean water (e.g. contaminated surface water) to survive. Water is often contaminated with harmful substances such as human and animal excreta and animal carcasses from upstream, making these infectious diseases very vulnerable to outbreaks. Malnutrition Ethiopia has high malnutrition rates, especially among children, with 46% stunting. The crops and floods suffered from food shortage in the region after the floods, leading to malnutrition among the people. Long-term Impact: Immune-deficiency in Residents Malnutrition and diarrheal mortality are inextricably linked. This is a vicious circle because malnutrition leads to deficiencies in the immune system, and conversely diarrhea leads to malnutrition because of reduced energy intake and malabsorption. The potential for waterborne diseases is also exacerbated by the reduced physical strength of the population due to food shortages and limited temporary living conditions, as well as the degradation of turbid drinking water. The poorer and more backward countries need time to rebuild after the disaster, and the healthy living standard of the Ethiopian people cannot be guaranteed in time. Response Local Response The National Disaster Risk Management Commission (NDRMCC) acted in a leading role. National humanitarian actors mainly include the Ethiopian Red Cross Society (ERCS), the National Flood Task Forces (FTF), National Meteorological Agency (NMA), Ethiopia Humanitarian Country Team (EHCT), Ethiopia Humanitarian Fund (EHF) and other National Society branches. ERCS was responsible for supporting NDRMC by dispatching NFI
