What Is Coronavirus?
coronaviruses are a kind of virus. There are many various kinds, and a few cause disease. A newly identified coronavirus, SARS-CoV-2, has caused a worldwide pandemic of respiratory disease , called COVID-19.
How does the new coronavirus spread?
As of now, researchers know that the new coronavirus is spread through droplets released into the air when an infected person coughs or sneezes. The droplets generally don't travel quite a couple of feet, and that they fall to the bottom (or onto surfaces) during a few seconds — this is often why physical distancing is effective in preventing the spread.
How did this new coronavirus spread to humans?
COVID-19 appeared in Wuhan, a city in China, in December 2019. Although health officials are still tracing the precise source of this new coronavirus, early hypotheses thought it's going to be linked to a seafood market in Wuhan, China. Some people that visited the market developed viral infection caused by the new coronavirus. A study that came out on Jan. 25, 2020, notes that the individual with the primary reported case became ill on Dec. 1, 2019, and had no link to the seafood market. Investigations are ongoing on how this virus originated and spread.
What are symptoms of COVID-19?
COVID-19 symptoms include:
Is this coronavirus different from SARS?
SARS stands for severe acute respiratory syndrome. In 2003, an epidemic of SARS started in China and spread to other countries before ending in 2004. The virus that causes COVID-19 is analogous to the one that caused the 2003 SARS outbreak: both are sorts of coronaviruses. Much remains unknown, but COVID-19 seems to spread faster than the 2003 SARS and also may cause less severe illness.
