Information

When you cough, talk or breath, you throw anywhere between 900 to 300,000 liquid particles (1.1) from your mouth. A cough can send them traveling at speeds up to 60 mph. (1.1)

Not every aerosol coming from an infected person will contain the coronavirus. There is a lot of chance involved.

But it's recommended to wear a face mask in any public setting (1.1) where social distancing is hard to do. This is because homemade masks probably do a reasonable job of blocking aerosols from leaving your mouth.

You can change the test conditions and past hours to see when 99,99% of the virus is decayed. Try it out!

Test Conditions

Lower temperature and humidity increases the survival rate of the virus. Higher temperature and humidity decreases the survival rate of the virus.

Past Hours

Time in hours until 99,99% of the virus on the surfaces is decayed without exposure to direct sunlight.

It’s important to note that the infectiouse dose of how much virus comes off from touching is still unknown.
