Sudden Disasters<\/p>\n<p>Sudden disasters are mishappenings triggered by a hazardous event that occurs unexpectedly and has tragic consequences affecting massive populations leading to loss of life and damage to property and resources.<\/p>\n<p>One example of a sudden disaster is the Bhopal gas tragedy, which occurred in India on December 3, 1984. Methyl isocyanate leaked into the air from a Union Carbide Pesticide Plant storage tank, exposing millions of people to it. 3000 people died as a result of the tragedy, and the adverse effects of the gas are still being felt by many.<\/p>\n<p>Another instance happened on April 26, 1986. It was an accident at reactor 4 of the Chernobyl nuclear power plant in the Soviet Union, where radioactive substances like iodine, caesium, and strontium were released.<\/p>\n<p>B. Insidious Disasters<\/p>\n<p>Insidious chemical exposure and pervasive chemical radiation exposure, such as those found in research labs, nuclear weapon manufacturing facilities, and manufacturing facilities, resulting in the emission of harmful substances into the air, land, and water. Another example is global warming.<\/p>\n<p>C. Wars &amp; civil conflicts<\/p>\n<p>One such example is an attack on the twin buildings of the World trade centre in New York in which around 6000 people lost their lives, and thousands were injured.<\/p>\n<p>Another instance is the US bombings of the Japanese cities of Nagasaki and Hiroshima, which led to the loss of thousands of lives.<\/p>\n<p><strong>Disasters in India<\/strong><\/p>\n<p>Snowstorms, landslides, and earthquakes commonly occur in the northern mountain region, while floods and cyclones frequently strike the eastern coastal zone. Desert regions in the west frequently experience droughts.<\/p>\n<p>Some of the Disasters that occurred in India include:<\/p>\n<ul>\n<li>Super cyclone in Orissa \u2013 1999<\/li>\n<li>Severe earthquake in Gujarat \u2013 2001<\/li>\n<li>Tsunami in Indian Ocean \u2013 2004<\/li>\n<li>Major earthquake in Jammu &amp; Kashmir \u2013 2005<\/li>\n<li>Cloudburst in Uttarakhand causing floods in Kedarnath \u2013 2013<\/li>\n<li>Floods in Kashmir \u2013 2014<\/li>\n<\/ul>\n<p><strong>Post Disaster phase<\/strong><\/p>\n<p>Diseases common in the post-disaster phase:<\/p>\n<ul>\n<li>Gastroenteritis (most common)<\/li>\n<li>ARI (Pneumonia)<\/li>\n<li>Leptospirosis<\/li>\n<li>Rickettsiosis<\/li>\n<li>Rabies<\/li>\n<li>Equine encephalitis<\/li>\n<\/ul>\n<p>Vaccines recommended by WHO in post-disaster areas:<\/p>\n<ul>\n<li>Health workers \u2013 Typhoid, Cholera &amp; TD<\/li>\n<li>General population- None<\/li>\n<li>Measles is the highest priority vaccine for children in disaster-affected areas as measles can deplete vitamin A (which is already deficient in disaster relief diets).<\/li>\n<\/ul>\n<p><strong>Post-disaster Disease Prevention:<\/strong><\/p>\n<ul>\n<li>The foremost step of disease prevention &amp; control is chlorination of all the water bodies.
