New Delhi:Dispelling apprehensions that mild and moderate COVID-19 patients could transmit the disease if not tested before being discharged, the Union health ministry said available evidence does not indicate any increase in risk of the infection's transmission in such cases.
Such patients after being discharged will also follow home isolation for further seven days, the ministry said in its Frequently Asked Questions (FAQs) on the Revised Discharge Policy.
The ministry on May 9 issued the new discharge policy according to which coronavirus infected patients developing severe illness or having compromised immunity will have to test negative through RT-PCR test before they are discharged by a hospital.
For moderate cases of COVID-19 and pre-symptomatic, mild and very mild cases, it said, they need not undergo tests before being discharged after the resolution of symptoms.
"Available evidence does not indicate any increase in the risk of transmission from patients discharged based on the revised discharge criteria.The revised criterion also specifies that such patients will follow home isolation for a further seven days," the ministry said in reply to the FAQs.
Mild, very mild and pre-symptomatic patients admitted to a COVID care facility can be discharged after 10 days of symptom onset and no fever for three days, according to the policy.
Patients clinically classified as moderate cases will be discharged after 10 days of symptom onset in case of absence of fever without antipyretics, resolution of breathlessness and no oxygen requirement, it said.

But in the both the cases severe cases, and moderate, mild and pre-symptomatic cases-- the patient after being discharged will have to follow home isolation for further seven days, the policy said.
Responding to a question over why the discharge policy was changed, the ministry said several countries have changed the criteria for discharge from 'test-based strategy to 'symptom-based strategy' or 'time-based 'strategy.
"A review of ICMR laboratory surveillance data also indicated that after initial RT-PCR positive results, patients became negative after a median duration of 10 days," it said.
Recent studies have also suggested that the viral load peaks in the pre-symptomatic period two days before symptoms -- and goes down over the next seven days.
