Small CDC study looks at SARS-CoV-2 viral shedding in vaccinated and unvaccinated CDCgov SARSCoV2 Coronavirus Disease COVID
By Suchandrima BhowmikNov 28 2022Reviewed by Aimee Molineux The risk of severe acute respiratory syndrome coronavirus 2 transmission can be assessed by determination of the time course of shedding using diagnostic indicators like cycle threshold values through the recovery of SARS-CoV-2 from viral culture and reverse transcription polymerase chain reaction testing.
About the study The study involved the collection of nasal swabs from incarcerated persons for reverse-transcription polymerase chain reaction and antigen testing every other day after exposure. Exposed people were moved to quarantine. Those with positive antigen tests were moved to medical isolation. A single swab was collected from the infected people daily for ten days and tested by viral culture and RT-PCR.
Study findings A total of 12 individuals were identified as eligible for this case series analysis. All were male and all identified as non-Hispanic White. The median age was reported to be 43 years. Out of 12 participants, 3 never had a positive antigen test.
Eleven participants reported at least one underlying medical condition, with overweight and a history of tobacco use disorder being the most common. Information on symptoms was available for 10 participants, out of which 4 were asymptomatic. However, 3 out of these 4 participants had at least one positive viral culture result post-first positive RT-PCR. The median duration for the onset of symptoms was reported to be 7 days.
