How it spread

It’s unclear how infectious the new coronaviruses are. Data have shown that virus spreads from person to person (within about 6 feet, or 2 meters). This deadly virus mainly transmitted by respiratory droplets released when a person with the virus coughs, sneezes, exhales, or talks. These droplets are heavy to hang in the air, so they quickly fall on floors or surfaces.

Some Researches have also shows that the virus can be airborne transmission which can live in the air for up to 3 hours. When you breathe air that has the virus floating in it, can affect you.

It can also spread if a person touches a floor or surface with the virus on it and then touches his or her eyes, nose, or mouth.

The majority of times viruses spreads through people who already have symptoms. But it may be possible to pass this virus on without showing any signs or symptoms. Some people who don’t know they’ve been infected by the virus can easily affect others. This kind of spread is called an asymptomatic spread. You can also pass it on before you notice any signs of infection within yourself, and it will be referred to as the presymptomatic spread.

A few pets have also tested positive for the new coronaviruses. The animals may have caught the virus from some close contact with humans who were infected. But there’s no study or evidence shown that pets play a role in its spread.


Since there is no vaccine available for the prevention of infection with the new coronaviruses, you can take steps to reduce your risk of infection.
