SARS-CoV-2 nucleic acid shedding is variable for every person

Authorship SCIMAGO INSTITUTIONS RANKINGS

Abstract

INTRODUCTION:

Considering the persistent positivity on RT-qPCR tests, the results of SARS-CoV-2 were monitored to evaluate the viral RNA shedding period.

METHODS:

Between March and June 2020, the sequential results of 29 healthcare workers’ were monitored using RT-qPCR.

RESULTS:

More than 50% of the individuals remained RT-qPCR positive after 14 days. Furthermore, this is the first study to describe positive RT-qPCR for SARS-CoV-2 in a healthcare worker with mild symptoms 95 days after the first positive test.

CONCLUSIONS:

Sequential RT-qPCR results were heterogeneous, and the viral RNA shedding period is unique for each person.
