COVID-19 symptoms vary in many aspects and also differ in the degree of risks. There are many signs of infection that may coincide with symptoms of other diseases, such as the common cold and the flu. In addition to that, some people infected with the virus do not show any signs of infection, which in itself can be very dangerous. That being said, it is almost impossible for you to find out whether you have contracted the virus or not, without getting yourself tested for the same. Courtesy – FROM TIMES OF INDIA .
