Head of epidemiology and communicable diseases at Indian Council of Medical Research Dr Raman R Gangakhedkar said 80 out of 100 infected people do not show any symptoms.
Head of Epidemiology and Communicable diseases at the ICMR Dr Raman R Gangakhedkar said the apex health research body will begin a study on the effectiveness of the vaccine against coronavirus infection next week.
These testing kits will be used for surveillance and to monitor whether coronavirus hotspots in the country are increasing or decreasing.
Addressing a daily media briefing to give updates on the COVID-19 situation in the country, Joint Secretary in the Health Ministry Lav Agarwal said most of the Markaz event-related cases have been found in states with high burden of the disease, such as Tamil Nadu (84 per cent), Telengana (79 per cent), Delhi (63 per cent), Uttar Pradesh (59 per cent) and Andhra Pradesh (61 per cent).
Joint Secretary in the Health Ministry Lav Agarwal claimed that India has been doing better than many other countries on the outcome ratio, which is the number of recoveries from coronavirus infection versus the number of deaths.
The death toll due to the coronavirus infection rose to 7,466 and the cases mounted to 2,66,598 in the country.
"We have received complaint from a state yesterday and so far discussed with three states. Too much variations have been reported in results of rapid test kits and RT-PCR kits. We advise states not to use them for the next two days," ICMR's Dr Raman R Gangakhedkar said.
'In countries like Japan, one out of 11.7 tests turns out to be positive, which is among the highest in the world. Italy tests 6.7 persons for one positive test while the USA tests 5.3 persons and the United Kingdom 3.4'
