World Health Organization’s Efforts to Combat El Nino’s Impact on Infectious Diseases and Food Insecurity
The World Health Organization (WHO) plays a crucial role in helping countries prepare for and mitigate the impacts of El Nino, a climate phenomenon that can exacerbate infectious diseases and food insecurity. El Nino, characterized by unusually warm ocean temperatures in the Equatorial Pacific, can lead to extreme weather conditions, including droughts and floods, which can in turn affect the spread of diseases and access to food. The WHO’s efforts in this area are multifaceted, encompassing disease surveillance, emergency preparedness, and strengthening health systems.
Understanding El Nino’s Impact on Health
El Nino can have significant health impacts, particularly in vulnerable populations. These impacts can be direct, such as injuries or deaths due to extreme weather events, or indirect, such as increases in vector-borne diseases like malaria and dengue fever, water-borne diseases like cholera, and food and water shortages leading to malnutrition.
WHO’s Role in Disease Surveillance and Response
The WHO works closely with countries to strengthen disease surveillance and response systems. This includes providing technical support to detect and respond to disease outbreaks, and helping countries develop and implement disease control strategies. The WHO also provides guidance on managing health risks associated with extreme weather events, such as heatwaves and floods.
For example, in response to the 2015-2016 El Nino event, the WHO supported countries in Southern Africa to enhance surveillance for malaria and other vector-borne diseases, and provided guidance on vector control and case management.
The WHO also worked with countries in the Pacific to prepare for and respond to the increased risk of dengue and other vector-borne diseases associated with El Nino.
WHO’s Role in Emergency Preparedness and Response
The WHO also plays a key role in emergency preparedness and response. This includes supporting countries to develop and implement emergency response plans, and providing technical and logistical support during emergencies.
For instance, during the 2015-2016 El Nino event, the WHO provided support to countries in Eastern Africa to prepare for and respond to the increased risk of food insecurity and malnutrition associated with drought.
The WHO also supported countries in South America to prepare for and respond to the increased risk of floods and landslides associated with El Nino.
Strengthening Health Systems
Finally, the WHO works with countries to strengthen health systems and build resilience to climate-related health risks. This includes supporting countries to develop and implement national health adaptation plans, and providing guidance on climate-resilient health systems.
In conclusion, the WHO’s efforts to combat El Nino’s impact on infectious diseases and food insecurity are comprehensive, encompassing disease surveillance and response, emergency preparedness and response, and health system strengthening. These efforts are crucial in helping countries prepare for and mitigate the health impacts of El Nino.
