Coronavirus Symptoms of Past Infection: 8 signs you may have already had COVID-19 without knowing

Coronavirus continues to rapidly surge across India and the world. With the global deaths having crossed the 3-million-mark, the COVID-19 pandemic is nowhere close to coming to a near end.

By this point, with high seropositivity levels, experts believe that there is a sizable population who may have already contracted the virus one way or the other, without actually having tested positive for the viral infection. There could also be many who may have gotten infected before COVID-19 was actually declared a pandemic and brought the world to a complete standstill.

Many also believe that while the infection is increasingly turning out to be symptomatic, with unusual signs and severe complications, a lot of cases in the last year, at the peak of the pandemic’s spread were asymptomatic. These people could also have some level of natural immunity against the virus.
