Viral fever vs corona: both can have common symptoms as Corona is also a viral infection (COVID-19). However, there are differences between viral Fever and Corona:
COVID-19 is more severe than viral fever and can lead to hospitalisation or fatal outcomes.
COVID-19 spreads more easily than viral fever, and the carriers could be contagious for a long time.
Symptoms of COVID-19 could take more time to show up (within 2-14 days, usually after five days) as the virus cycle is longer as compared to viral fever (within 1-4 days).
