The initial symptoms of COVID-19 and the flu are often very similar. They both cause fever and similar respiratory symptoms, which can range from mild to severe. See below for a comparative guide. While these are similar, it has been found the COVID-19 has resulted in more severe and critical cases than the flu.
The speed of transmission also differs between COVID-19 and the flu. The flu has a shorter incubation period (the time from infection to appearance of symptoms) of 2 days. Whereas COVID-19 has a longer incubation period, currently estimated to be between 2-14 days to develop symptoms according to the CDC. This means that the flu can spread faster COVID-19.
Both viruses are transmitted the same way, by sneezing or coughing, or by contact with hands, surfaces or objectives that are contaminated by the virus. Therefore, it is important that you follow good hand hygiene, good respiratory etiquette and good household cleaning behaviors.
