How the COVID-19 virus is transmitted?

The COVID-19 virus moves from one person to another like a sneaky guest at a party.

Imagine you're playing with your best friend. When they cough or sneeze, tiny invisible bubbles, called droplets, pop out of their mouth and nose. These droplets are like little messengers carrying the virus. If you’re close enough, you might breathe them in or touch something they touched, and then touch your face, poof, the virus gets into your body.

How it sneaks in

When someone coughs, sneezes, or even talks loudly, those droplets float through the air. If you're near them, like sitting next to them on the bus, some of those droplets might land on your face, especially if you don’t have a mask on.

How it hides and travels

Sometimes, the virus doesn't just travel in the air. It can also stick to surfaces, like doorknobs, phones, or toys. If you touch one of these things after someone who has the virus touched it, and then you touch your nose or mouth, the virus sneaks into your body too.

It's like playing a game of tag, the virus is tagging you, and now it’s your turn to be the tagger!
