Covid-19 cases are identified by taking specimens from people and testing them for the presence of the SARS-CoV-2 virus. If the test is positive - except for rapid lateral flow tests which have negative confirmatory lab-based PCR tests taken within 72 hours - this is referred to as a case. If a person has more than one positive test, they are only counted as one case for all nations with the exception of Wales.
