Explain Coronavirus origin
Answers
Answer:
Several of the early cases had visited Huanan Seafood Wholesale Market and so the virus is thought to have a zoonotic origin. The virus that caused the outbreak is known as SARS‐CoV‐2, a newly discovered virus closely related to bat coronaviruses, pangolin coronaviruses, and SARS-CoV.
The scientific consensus is that COVID-19 has a natural origin. The probable bat-to-human infection may have been among people processing bat carcasses and guano in the production of traditional Chinese medicines.
The earliest known person with symptoms was later discovered to have fallen ill on 1 December 2019, and that person did not have visible connections with the later wet market cluster. Of the early cluster of cases reported that month, two-thirds were found to have a link with the market.
Answer:
Coronavirus is not the name of a single virus. Coronaviruses are a family of respiratory viruses, named for the crown-like spikes on their surface.
Most common symptoms of COVID-19 are fever, tiredness, and dry cough. Symptoms may appear 2-14 days after exposure and vary in severity.
Simple measures like washing your hands often with soap and water can help stop viruses like coronavirus (COVID-19) spreading.
There's no specific treatment for coronavirus (COVID-19). People with COVID-19 should receive supportive care to relieve symptoms. Currently there is no vaccine to prevent the disease.
The disease can spread from person to person through small droplets from the nose or mouth when a person with COVID-19 coughs or exhales. People can also catch COVID-19 by touching objects or surfaces (where droplets land), then touching their eyes, nose or mouth.
