Here is country by country information on what isolation is required. All this information is a direct quote foreign travel advice/gov.uk and is subject to change at any time. If you test positive, be sure to check on current requirements to confirm.
Testing positive for COVID-19 in Germany
Anyone testing positive with a self-test is entitled to take a follow-up certified rapid antigen test or PCR test. Those testing positive with a certified rapid antigen test or PCR test are required to self-isolate. Mandatory self-isolation ceases after 5 days. The German authorities recommend staying in self-isolation until you test negative with a rapid-antigen test. The Federal Health Ministry provides guidance on self-isolation.
The local health office (Gesundheitsamt) is responsible for monitoring self-isolation and will provide further guidance in individual cases. You can find your local health office by postcode.
Testing positive for COVID-19 in Austria
If you get a positive PCR test result, you will have to self-isolate immediately. You should contact the health authorities for further instructions by calling 1450.
If you test positive with a lateral flow test, you will be treated as a “suspected case” and must self-isolate immediately, following the instructions of the health authorities. A lateral flow test will usually be followed up with a PCR test. If the PCR test is negative, you can leave self-isolation.
Options for self-isolation vary by region. In Vienna, a free hotel is available for visitors who test positive and have nowhere else to self-isolate.
Rules for ending self-isolation after a confirmed infection vary by region and may require a negative PCR test. They should be communicated to you as part of the official order to self-isolate (“Absonderungsbescheid”).
Testing positive for Covid in Switzerland
COVID-19 restrictions
Switzerland has lifted all Covid-19 pandemic restrictions – there are no social distancing or mask wearing measures in place. There is no mandatory isolation requirement if you test positive for Covid19. Local restrictions or mandatory mask wearing and proof of vaccination may be in place in hospitals or care homes.
However, you should follow the basic principles on hygiene to protect yourself and others. If you feel unwell, it is advised to stay at home. If you have Covid-19 symptoms, it may be a good idea to get tested, especially if you are at high risk. The costs of the test are covered by the Swiss government.
Testing positive for Covid in France
If you test positive for COVID-19 in France and you’re fully vaccinated (including a booster) or if you’ve had COVID-19 in the last 4 months, you must self-isolate for 7 days from the day on which you first develop symptoms, or 7 days from the date of the positive test result. Self-isolation can be reduced to 5 days if you take a negative PCR or antigen test (supervised, not self-administered) on day 5 and you have not displayed any symptoms over the previous 48 hours. These isolation rules also apply to children under the age of 12, regardless of their vaccination status.
