Leone: There are varieties of bacteria's and virus's are living inside human body. Some say Corona virus comes from one such virus family. Is it true doctor? Dr. Jaya: The Scientific answer is no. When new such virus enters our body, it brings severe diseases. The bacteria and virus which are inside our body will have a good relation to come extent. For example our food pipe has many bacterias. These bacterias are living with us from thousands of years and it helps us alot. It produces Vitamin B. Naturally our bodies cannot create Vitamin B. But the bacterias in our food pipes does this job for us and its an useful micro nutrient. rom thousands of years we have so many bacteria in our body. From the time when human used to live in caves till now after so many evolutions we have those bacterias in our body. Actually these virus forms placenta and helps to supply the nutrient to the babies inside the womb. So virus is the main reason behind the formation of placenta. So we have good relation with virus but the new virus enters our body looks human body as a food material. Thats why these side effects are happening and SARS Covi 2 which has affected the whole world and created Corona virus is a new virus. This is a virus which our body never had. Now if a person breathes the air which has SARS Covi 2 virus, the virus enters our lungs. These virus has small spikes around its body. It enters as the keys inside our body and our body has small cells like key holes in our body. These spike on the virus enters the key holes and enters our cells. When it enters our cells it doubles in its numbers. And it goes in search of many other cells. Like this one by one it enters the cell and it affects our lungs. It doubles in many numbers and affects our lungs and results in breathing issues.
