CORONA VIRUS-ORIGIN Coronavirus cause: Origin and how it spreads Many health experts believe that the new strain of coronavirus likely originated in bats or pangolins. The first transmission to humans was in Wuhan, China. Since then, the virus has mostly spread through person-to-person contact.Coronaviruses are a group of viruses that can cause disease in both animals and humans. The severe acute respiratory syndrome (SARS) virus strain known as SARS-CoV is an example of a coronavirus. SARS spread rapidly in 2002–2003.The new strain of coronavirus is called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The virus causes coronavirus disease 19 (COVID-19). Around 80% of people with COVID-19 recover without specialist treatment. These people may experience mild, flu-like symptoms. However, 1 in 6 people may experience severe symptoms, such as trouble breathing. Reports of the first COVID-19 cases started in December 2019.Some reports trace the earliest cases back to a seafood and animal market in Wuhan. It may have been from here that SARS-CoV-2 started to spread to humans. How it spreads When people with COVID-19 breathe out or cough, they expel tiny droplets that contain the virus. These droplets can enter the mouth or nose of someone without the virus, causing an infection to occur. The most common way that this illness spreads is through close contact with someone who has the infection. Close contact is within around 6 feet. The disease is most contagious when a person’s symptoms are at their peak. However it is possible for someone withoutsymptoms to spread the virus. A new study suggests that 10% of infections are from people exhibiting no symptoms. On April 6, Spain, one of the world's worst-hit countries, reported 4,237 additional cases of the coronavirus with 637 new deaths, the fourth day the daily totals declined from the previous day. Meanwhile, the United States entered one of the most critical weeks so far, with government officials warning the high death toll in New York.In the UK, Prime Minister Boris Johnson was moved into intensive care as his condition has worsened since being hospitalised with persistent COVID-19 symptoms, his Downing Street office said in a statement.On the same day, Iran, the worst-hit country in the Middle East, reported a total death toll of 3,603 amid 58,226 cases.209 Countries and Territories around the world have reported a total of 1,349,877 confirmed cases of the coronavirus COVID-19 that originated from Wuhan, China, and a death toll of 74,820 deaths.
