Dr. Jaya: Remaining 3 virus will cause severe disease in our body. 1st disease will be, it affects the lungs and it makes the lungs to unable to breath. The person will struggle alot to take breath. This is a acute syndrome. The person will have further more symptoms like fever, body pain. So this is called Severe acute Respiratory syndrome. In middle East they have MERS Respiratory syndrome. That is Middle East respiratory syndrome. This is another corona virus and it affected body very badly. Now there are no many cases of this virus. So SARS Covi 1, SARS Covi 2, MERS Covi these 3 corona virus affects human lungs and other few body parts. Leone: From where did this corona virus came? Dr. Jaya: Till now Scientists are unable to find it out. Initially many people believed that this virus was found among the people who work in a wild life meat selling place of China but other than the people who worked in the people there were many other people who got this virus. So we are unable to find it out whether we got this virus from that wild life meat market or from any other place. But now the guess is, usually we eat mutton, beef, other than this, naturally in forests there will be few special animals. Some Chinese or some people might have caught this animal for example, Pangolin, some kinds of monkeys, snakes, when such different animals are sold in market, mostly from Pangolin which eats ants, from this animal we might have got this disease. These animals might have got this from bats from the forest. This is just a guess. So far there is no official confirmation about it.
