On May 18, the ICMR revised its strategy for COVID-19 testing. As per the new guideline, those with a history of international travel in the past 14 days, who show Influenza-like Illness (ILI) symptoms — acute respiratory infection with fever more than 38ºC coupled with cough — will be tested.

Considering that migrant workers and expatriates are returning to their native states, all returnees and migrants, who exhibit symptoms, will be tested within seven days of developing an illness.

Additionally, all asymptomatic direct and high-risk contacts of a confirmed case will be tested once between day 5 and 10 of coming into contact with a COVID-19 patient, unlike previously between day 5 and 14.

The other patients that will be tested include:

* Symptomatic contacts of laboratory-confirmed cases
* Symptomatic health care workers or frontline workers involved in containment and mitigation of the disease
* Severe Acute Respiratory Infection (SARI) patients
* Symptomatic individuals within hotspots and containment zones
* Hospitalised patients who develop symptoms

The ICMR has recommended that all testing be done only with real-time RT-PCR or the reverse transcription polymerase chain reaction test. This test can detect the presence of SARS-CoV-2, the virus that causes COVID-19.
