Hide AdLike many other coronaviruses, the Covid-19 strain is often spread through the air in tiny droplets from the noses and mouths of infected people.
Each cough can fire around 3,000 droplets onto other surfaces. The droplets can land on the surfaces themselves, or be carried there by unwashed hands that were used to cover the cough.
The virus can be spread to dozens of commonly touched surfaces, like desks and tables, computers, phones and stationery - as well as door handles and light switches.

Studies on other types of coronavirus, like Sars and Mers, discovered that the viruses can survive outside the body for up to nine days at normal temperatures - and for four weeks in cold climates.
But scientists are still not sure exactly how long Covid-19 can survive on surfaces outside of the body.

Hide AdHow is it spread?As this is such a new illness, experts still aren’t sure how it is spread. But.similar viruses are spread in cough droplets. Therefore covering your nose and mouth when sneezing and coughing, and disposing of used tissues straight away is advised. Viruses like coronavirus cannot live outside the body for very long.
What are the symptoms?The NHS states that the symptoms are: a dry cough, high temperature and shortness of breath - but these symptoms do not necessarily mean you have the illness. Look out for flu-like symptoms, such as aches and pains, nasal congestion, runny nose and a sore throat. It’s important to remember that some people may become infected but won’t develop any symptoms or feel unwell.
What precautions can be taken?Washing your hands with soap and water thoroughly. The NHS also advises to cover your mouth and nose with a tissue or your sleeve (not your hands) when you cough or sneeze; put used tissues in the bin immediately and try to avoid close contact with people who are unwell. Also avoiding touching eyes, nose and mouth unless your hands are clean.
