There are certain settings where COVID-19 can spread easily thereby increasing the risk of getting COVID -19 .Any situation in which people are in close proximity to one another for long periods of time increases the risk of transmission. Indoor locations, especially settings where there is poor ventilation, are riskier than outdoor locations. Activities where more particles are expelled from the mouth, such as singing or breathing heavily during exercise, also increase the risk of transmission.
The “Three C’s” are a useful way to think about this. They describe settings where transmission of the COVID-19 virus spreads more easily:
- Crowded places;
- Close-contact settings, especially where people have conversations very near each other;
- Confined and enclosed spaces with poor ventilation.
The risk of COVID-19 spreading is especially high in places where these “3Cs” overlap
There are many things you can do to keep yourself and your loved ones safe from COVID-19. Know your risks to lower risks. Follow these basic precautions:
- Follow local guidance: Check to see what national, regional and local authorities are advising so you have the most relevant information for where you are.
- Keep your distance: Stay at least 6 feet away from others, even if they don’t appear to be sick, since people can have the virus without having symptoms.
- Wear a mask: Wear a well-fitting three-layer mask, especially when you can’t physically distance, or if you’re indoors. Clean your hands before putting on and taking off a mask.
- Avoid crowded places, poorly ventilated, indoor locations and avoid prolonged contact with others. Spend more time outdoors than indoors.
- Ventilation is important: Open windows when indoors to increase the amount of outdoor air.
- Avoid touching surfaces, especially in public settings or health facilities, in case people infected with COVID-19 have touched them. Clean surfaces regularly with standard disinfectants
- Frequently clean your hands with soap and water, or an alcohol-based hand rub. If you can, carry alcohol-based rub with you and use it often.
- Cover your coughs and sneezes with a bent elbow or tissue, throwing used tissues into a closed bin right away. Then wash your hands or use an alcohol-based hand rub.
- Get vaccinated: When it’s your turn, get vaccinated. Follow local guidance and recommendations about vaccination.
