Participants then quarantined for a suitable amount of time with routine follow-ups for the next 12 months.The pre-print results — meaning it has not been peer reviewed — indicate that the virus was detectable in the throat of patients as early as 40 hours after exposure, contrary to the common recommendation to wait five days after exposure before testing for COVID-19.

“Our study reveals some very interesting clinical insights, particularly around the short incubation period of the virus, extremely high viral shedding from the nose…with potential implications for public health,” said Prof. Christopher Chiu, chief investigator on the trial, asThe participants, none of whom exhibited “serious safety signals” throughout the study, were compensated £4,565 . The study was conducted at the Royal Free Hospital in London, England.

The virus was still detectable for some time after the exposure. Participants were initially supposed to quarantine for 14 days, but at the end of the original trial all infected patients still had levels of the virus over a determined threshold and had to continue to quarantine for five more days until the virus levels detected by qPCR fell. The virus was not detectable in any of the patients after day 90.

Twelve participants also reported trouble with their sense of smell, with nine reporting complete loss of smell. This symptom took longer to develop and seemed to stick around, with 11 of the participants still reporting some smell disturbance by day 28. One individual still had “measurable” smell impairment by day 180, although it was reportedly improving.
