Puyehue Volcano in Chile, which last erupted in June causing the evacuation of 4,000 people, is once again showing signs of activity. Back in June, the National Emergency Office (ONEMI) maintained a Red Alert in communities from Los Lagos and Los Rios Regions. The city of Bariloche, in Argentina, was declared in a state of economic and social disaster as a result of the devastating effects of the volcano. Major roads, as well as crop areas, were covered by thick layer of ashes.
In this situation, the health sector response has been swift. Health facilities assist the population during extended hours and the national authorities have already sent to the area 310,000 masks, eye drops, chlorine tablets and water purification equipment. Health recommendations in these cases are aimed to ensure quality control of air and drinking water, to prevent diseases caused by volcanic ash and to maintain sanitary conditions in shelters and waste disposal, among others.
Most active volcanoes in the world are in Latin America and the Caribbean, and millions of people live in villages and towns located nearby. Throughout history, many of these volcanoes have shown great capacity for destruction. In order to avoid loss of lives and damages, PAHO/WHO continues to provide support to countries to prepare contingency plans in the health sector to deal with such emergencies.
