Coronavirus disease 2019( Covid-19) is an infectious disease caused by severe acute respiratory syndrome corona virus 2(SARS COV-2).This disease was first identified in December 2019 in Wuhan, the capital of China’s Hubei province and has since spread globally resulting in the ongoing 2019-20 corona virus panademic.
Covid-19 virus is not a living organism,it is a protein molecule which cover DNA and again this protein layer covered by a protective layer of lipid(fat).When this virus absorved by the cells of the ocular, nasal or buccal mucosa, changes their genetic code(mutation) and convert them into aggressor and multiplier cells. Common symptoms include fever, cough,fatigue shortness of breath and loss of smell. While the majority of cases resulted in mild symptoms, some progress to virul pneumonia, multi -organ failure or cytokine storm.More concerning symptoms include difficulty breathing,persistent chest pain,confusion, difficulty waking and bluish skin.The time from exposure to onset of symptoms is typically around five days but may range from 2-14 days.
Though the virus is not a living organism like bacteria,they can not kill by antibiotics. It is nothing but a protein molecule which decays on its own.The disintegration time depends on the temperature, humidity and type of material where it lies. As a fatty layer covers the protein molecule and heat melts fat,so hot water can remove the fatty layer from the protein layer and then the protein molecule disperses and break down in its own. Alcohol or any mixture with alcohol over 65% dissolves any fat,especially the external lipid layer of the virus. Moreover any mix with 1 part bleach and 5 parts water directly dissolves the protein, breaks it down from the inside.
The virus molecules remain very stable in external cold or artificial as air conditions in houses and cars.They also need moisture to stay stable and especially darkness.Therefore, dehumidified dry,warm and bright environments will degrade it faster. The virus cannot go through healthy skin.
The virus is primarily spread Between people during close contact, often via small droplets produced by coughing,sneezing or talking.The droplets usually fall to the ground or onto surfaces rather than remaining in the air over long distances. People may also become infected by touching contaminated surface and then touching their face.It is most contagions during the first three days after the onset of symptoms, although spread may be possible before symptoms appear and in later stages of the disease
At last,as no vaccine is invented to destroy the virus, so the only way to keep ourselves safe is to stay home…. Please,,, Stay Home,Stay Safe.
