Although the virus is contagious and may be potentially life-threatening in a few people, the risk of contracting it in South Africa is currently low, with no cases having been confirmed in this country at this time.
How is the virus spread?
The COVID-19 virus is spread in a similar way to influenza (flu) viruses, which is through:
- Direct contact with other infected people.
- Droplets generated through coughs or sneezes.
- Contact with infected surfaces such as tabletops and shared objects like utensils etc.
- Fecal-oral contact.
What measures can you take to avoid being infected?

- Avoid touching your eyes, and/or nose as much as possible.
- Use a tissue when sneezing or coughing and then get rid of the tissue in a bin. Always wash your hands afterwards. If there is no tissue it is advisable to cough or sneeze into your upper sleeve or elbow, and not your hands.
- Maintain good hygiene habits and disinfect frequently touched objects and surfaces.
