SARS-CoV-2 -RNA persists longer in faecal sample as compared to nasal and throat swab samples of COVID-19 patients'; an observational study.

ABSTRACT

The route of transmission of Novel SARS-CoV-2 virus is ambiguous. In this regard we planned a study to find out SARS-CoV-RNA shedding in various clinical samples of 9 COVID-19 positive patients. SARS-CoV-RNA was detected in nasal swab (NS), throat swab (TS) and faecal sample but was not detected in serum and urine samples. We also report that SARS-CoV-2-RNA persisted in faeces for >20 days. Persistence of faecal RNA might impose challenge in infection control and the disease may spread to household contacts if discharged. Perineal cleaning and hygiene may be advised at the time of vaginal delivery.
