According to new reports, the longest viability period of the Coronavirus in patients is 10 days.

The study was carried out by infectious diseases experts in Singapore.

The Director General of Nigeria Centre for Disease Control, Dr. Chikwe Ihekweazu, disclosed this at the Presidential Task Force media briefing on Wednesday in Abuja.

The News Agency of Nigeria reports that the Singapore study shows that COVID-19 patients are no longer infectious after 11 days of getting sick even though some may still test positive.

“A positive test does not equate to infectiousness or viable virus,” a joint research paper by Singapore’s National Centre for Infectious Diseases and the Academy of Medicine Singapore said.

The virus “could not be isolated or cultured after day 11 of illness.”

The paper was based on a study of 73 patients in the city-state.

Ihekweazu said the agency’s strategy on managing COVID-19 patients was guided by the latest local and international clinical scientific evidence, and the NCDC would evaluate if the latest evidence could be incorporated into its patient clinical management plan.

The DG said in line with this latest findings, the agency would release a new case management guidelines for COVID-19 to review criteria for admission and discharge of patients.

He noted that the move would assist in managing challenges faced in isolation centres across the country, particularly with the shortage of bed space.

“We are now relooking our practice in terms of discharge criteria, and even who to keep in hospital, and who can stay at home and for how long.

Ihekweazu, however, said the new guidelines would be released soonest to assist the country better tackle the virus.

“If we are able to do this successfully, it will have good implications on the duration of time people spend in hospital and when they can be discharged.

“That will enable us bring in people more frequently, it will ease up some of the bed space and help us in some of the practical challenges we have.”
