Public health experts have called for wider testing to check for community transmission of COVID-19. The Indian Council of Medical Research’s (ICMR) testing strategy has been expanded and all symptomatic patients with influenza-like illness (ILI) - those with fever, cough, sore throat, runny nose - need to be tested in hotspots/clusters (identified by the Ministry of Health and Family Welfare) and in large migration gatherings/ evacuees centres. Symptomatic ILI patients will have to be tested within seven days of presenting with the illness.
Earlier, the guidelines limited testing to those who have international travel history and are symptomatic; those who have contact history with a confirmed COVID-19 case and have symptoms of the virus; healthcare workers who are symptomatic; patients hospitalised with Severe Acute Respiratory Illness (SARI); and a direct or high-risk contact of a confirmed COVID-19 case who can be symptomatic or asymptomatic.
Presently, only the RT-PCR or the reverse transcription polymerase chain reaction test can detect the presence of SARS-CoV-2, the virus that causes COVID-19. However, ICMR has allowed places that are hotspots (high number of cases) to test residents using the rapid antibody kits, which can deliver results within 30-45 minutes as opposed to 24 hours that an RT-PCR test. However, a positive result by the rapid antibody test will have to be further tested by the RT-PCR test to confirm for the novel coronavirus. ICMR advises those with a negative result by the rapid antibody test to be home quarantined.
