It means that you have to stay home and avoid meeting people you do not live with. Do not go to work, avoid shopping and walks, and ask others to walk the dog. Get help if you need to do shopping, and have goods delivered outside your door. Use a CE-certified face mask, i.e. a surgical mask. Keep a distance to others.
Avoid close physical contact with others at home - especially if you are living with a person in risk of severe illness from a covid-19 infection. Sleep in separate rooms if possible, and avoid spending a lot of time in the same room. Use separate bathrooms and toilets if possible. If not, you should clean surfaces, water taps and door handles thoroughly.
Significant symptoms of covid-19 are symptoms such as fever, sore throat, persistent cough, sneezing or breathing problems. In this case, you generally feel sick without necessarily feeling like you need help.
If you experience significant symptoms of covid-19, you should self-isolate for at least 4 days after your positive test result.
Mild or asymptomatic symptoms
Mild symptoms of covid-19 are symptoms such as a runny nose, throat tickles, and a few coughs that will typically be transitory. In this case, you do not feel really sick.
If you test positive for covid-19 with mild symptoms or no symptoms of covid-19, you should self-isolate for at least 4 days after your positive test result.
