The virus spreads easiest indoors, especially in places where there is poor ventilation. If there is no fresh air to move the virus away, it will stay in the air or land on surfaces.
The virus is like smoke, in this way - if a window or door is not open, the virus cannot leave a room. The longer you spend in that room, the more chance you might inhale the virus, if it is in the air.
Meeting other people
No visitors are allowed inside your home except for:
If you have visitors to your home, ask them to clean their hands when they arrive. After they leave, clean surfaces they have been in contact with. Use your usual household cleaning agents and detergents.
Do not wear disposable gloves instead of washing your hands. The virus gets on them in the same way it gets on your hands. Also, your hands can get contaminated when you take them off.
The most common way you can get COVID-19 is by coming into close contact with someone who has the virus. You can spread the virus even if you do not have symptoms.
COVID-19 is mainly spread through close contact and droplets that come from your nose and mouth. For example, from someone who is talking loud, singing, shouting, coughing or sneezing.
This happens when people are within 1 to 2 metres of each other.
That's why keeping a 2 metre distance from other people is an important way of reducing the spread of COVID-19.
Airborne transmission is the spread of a virus in very tiny water particles, known as aerosols. This can happen over a longer distance than droplets, such as across a room.
COVID-19 can spread easily in crowded or poorly ventilated areas.
To protect against airborne transmission, keep indoor spaces aired out (ventilated) by opening windows and doors when possible. This reduces the risk of infected air building up in a room, corridor or stairwell.
It's much safer to meet people outdoors than indoors, even if you keep more than 2 metres apart indoors.
Avoid crowded or stuffy places as much as possible. Leave a location if it becomes crowded.
You can also get the virus from infected surfaces. For example, when someone who has the virus sneezes or coughs, droplets with the virus can fall onto surfaces around them.
If you touch that surface and then touch your eyes, nose or mouth, you could become infected too.
Getting COVID-19 from surfaces is not as common as getting it through close contact with someone who has the virus. But it's still important to wash your hands properly and often.
Using common household disinfectants will kill the virus on surfaces.
