Head of epidemiology and communicable diseases at Indian Council of Medical Research (ICMR) Dr Raman R Gangakhedkar also stated that 80 out of 100 infected people do not show any symptoms.
Health experts said that lockdown and social distancing are the only way to prevent transmission from asymptomatic cases in a populous country like Indian with limited testing capacity.
Dr Robert Redfield, director of the Centers for Disease Control and Prevention (CDC) in the US, claimed that as many as 25 per cent of people infected with the new coronavirus remain asymptomatic. In a recent interview, Redfield had said,”That’s important, because now you have individuals that may not have any symptoms that can contribute to transmission”.
According to Dr Neha Gupta, Consultant, Infectious Disease, Fortis Memorial Research Institute, Gurugram, 25-50 per cent patients do not have any symptoms as per CDC and Iceland data, and are contagious. Speaking to a news agency, Gupta said,”That’s why lockdown is even more essential to prevent transmission from these likely to be missed out asymptomatic cases when the population is large and testing capacity is limited.”
“Lockdown restrictions can be eased out in areas where no COVID 19 is documented in the last 14 days as most cases take this to recover. But the incubation period can be as long as 27 days and 2.5 per cent of the COVID-19 can develop infections beyond the 14-day incubation period,” she informed.
India is currently under an extended lockdown till May 3.
