Yes, there have been a lot of errors in diagnosing COVID-19 due to the similarity of symptoms to other infections, such as the flu, as well as limitations of current testing technologies. As such, it is important for healthcare professionals to use a stepwise approach to diagnosis when evaluating someone for possible COVID-19. This involves ruling out other conditions first, and then assessing the severity and risk of exposure to COVID-19. Additionally, many errors have been made by people self-testing, due to lack of education and the misinterpretation of results. It is important to double-check self-tests with health professionals before deciding on a diagnosis.
