Preliminary findings of Dr. Benjamin Smith's study suggest a shorter COVID-19 quarantine period may be possible for the future.

A shorter COVID-19 quarantine period

It seems that a shorter COVID-19 quarantine period may be possible, thanks to the work of Dr. Benjamin Smith, MI4 scientist and member of the Meakins-Christie Laboratories. Dr. Smith was primarily looking to ease the burden of this virus on the healthcare system. Healthcare workers are at the greatest risk of exposure while at work and yet their presence at work is crucial to handle an ever-increasing influx of COVID-19 patients.

Dr. Smith began by questioning the duration of the isolation period after exposure, 14 days, and looked to reduce that window. He developed a study, and is using healthcare workers exposed to the virus as his test subjects. Testing them using a variety of methods at varying time intervals throughout their isolation has given positive results.

“Our study suggests that a simple infection control strategy consisting of symptom-triggered testing from day 0 to 7, followed by a standard home-based test on day 7, detects all or nearly all healthcare workers who develop COVID-19 after high-risk exposure. It’s a promising result. If these findings are confirmed as we test a larger number of people, this testing strategy could significantly shorten the self-isolation duration required for healthcare workers,”

The initial findings of his study indicate that the results of a nasopharyngeal swab and saliva test on the 7th day of quarantine will predict fairly accurately the likelihood of developing the virus in day 8-14. Continued positive results in this ongoing study will bring a great sense of relief to many. A shorter COVID-19 quarantine period will benefit more than just the intended healthcare workers. Other patients looking to access the healthcare system, travellers, society as a whole will feel a burden lifting in light of this news.
