Over 70% children with Covid-19 are asymptomatic: AIIMS data

Almost 40% of all the persons who tested positive for coronavirus disease (Covid-19) across age groups were found to be asymptomatic, as per data from the All India Institute of Medical Sciences. The data was presented while discussing sensitivity and use of various detection tests by the doctors at the recent National Grand Rounds, a virtual platform for doctors across the country to discuss recent trends and issues in Covid-19 management.

“This is the data from our centre. The relevance comes in when we question the validity of an RT PCR test. As there are no symptoms in many of the patients, we do not come to know on which day we are sampling them,” said Dr Urvashi Singh, professor, department of microbiology at AIIMS.

The data from the centre showed that the most common symptoms of Covid-19 were fever, fatigue, and loss of smell.

“In cases of emergency, one should proceed thinking that the person is positive and take all the precautions. However, in case of semi-emergency, CBNAAT and TrueNat are good tests that can give accurate results quickly and can help in deciding whether a surgery should be performed at the Covid-19 centre,” said Dr Randeep Guleria, director, AIIMS.

The doctors also added that there were benefits of the less sensitive rapid antigen test as it can quickly help in screening a positive person in the hospital emergency and allow swift treatment, like in the case of a 65-year-old who came in with sepsis to the hospital.

The Indian Council of Medical Research recommends molecular tests as the preferred method in hospital settings.
