While flu viruses can cause mild to severe illness, which can be treated without any hospitalisation, COVID-19 is a more deadly form of disease, which can lead to severe medical complications and can prove fatal.
As per CDC, a person suffering from the flu will develop symptoms anywhere from 1 to 4 days after infection, whereas a COVID positive individual can experience symptoms 5 days after being infected. However, symptoms can appear as early as 2 days after infection or as late as 14 days after infection.
That said, when it comes to the differences between COVID-19 and the flu, there are three main points of difference
– Shortness of breath is common with COVID-19 but not with the flu.
– Unlike coronavirus, loss of sense of smell or taste is very rare with flu.
– Feeling sick or nauseous is more frequent with COVID and less so with the flu.
