Moreover, ICMR notes that 80% of cases in India are asymptomatic. Another published study lays out the fact that 40-45% of individuals are asymptomatic. It means the COVID-19 is prone to silently spread faster in human populations across the globe than previous assumptions.
Concurrently, the UK shows the same pattern where 22% of individuals who test positive for COVID-19 are asymptomatic at the testing time. In fact, one of Italy’s towns revealed up to 40% of its individuals were asymptomatic carriers.
Contrary to misguided perception, the asymptomatic transmission is not an unusual occurrence. So far, the studies prove that it may be the chief driver of the pandemic, which means there will have to be even more rigorous detecting and testing.
