Coronavirus is a type of virus. As a group, coronaviruses are common across the world. COVID-19 is a new strain of coronavirus first identified in Wuhan City, China in January 2020.
The incubation period of COVID-19, is between 2 to 14 days. This means that if a person remains well 14 days after contact with someone with confirmed coronavirus, they have not become a case.
The following symptoms may develop in the 14 days after exposure to someone who has COVID-19 infection:
- difficulty in breathing
Generally, these infections can cause more severe symptoms in people with weakened immune systems, older people, and those with long-term conditions like diabetes, cancer and chronic lung disease.
6. Preventing the spread of infection
There is currently no vaccine to prevent COVID-19. The best way to prevent infection is to avoid being exposed to the virus.
There are general principles anyone can follow to help prevent the spread of respiratory viruses, including:
- washing your hands often – with soap and water, or use alcohol sanitiser that contains at least 60% alcohol if handwashing facilities are not available – this is particularly important after taking public transport. Guidance is available on hand washing
- covering your cough or sneeze with a tissue, then throwing the tissue in a bin. See Catch It, Bin It, Kill It
- people who feel unwell should stay at home and should not attend work
- employees should wash their hands:
- before leaving home
- on arrival at work
- after using the toilet
- after breaks and sporting activities
- before food preparation
- before eating any food, including snacks
- before leaving work
- on arrival at home
- avoid touching your eyes, nose, and mouth with unwashed hands
- clean and disinfect frequently touched objects and surfaces
- if staff are worried about their symptoms or those of a family member or colleague, please call NHS 111. They should not go to their GP or other healthcare environment
