Abstract
Rapid antigen tests have emerged to deal with the COVID-19 pandemic. Rapid diagnosis of SARS-CoV-2 infection is essential to reduce the spread of the disease. The aim of this study was to estimate the prevalence of COVID-19 infection and test the sensitivity and specificity in Temara-Skhirat in symptomatic adults through PANBIOS® test. A prospective observational study was conducted in mid-September 2021. Two investigators conducted data collection from symptomatic adult patients. The diagnostic performance of the PANBIOS®, and the PCR was assessed to calculate sensitivity and the specificity. Among 206 symptomatic participants, the mean age was 38 ± 12 years, and the majority were women (59%). In our population, 80% had benefited from the anti-COVID vaccine. The median duration of symptoms was 4days; the most common symptoms were fatigue (62%), headache (52%), fever (48%), cough (34%), loss of smell (25%), loss of taste (24%), and sore throat (22%). Results revealed 23% of cases tested positive with PANBIOS® test versus 30% with the PCR test. The calculated medical decision between PCR versus PANBIOS® test showed high specificity of 95.7% and a sensitivity of 69.4%. There was concordance between the PANBIOS® test and the PCR. The prevalence tested remain high, and the sensitivity and specificity of the PANBIOS® versus PCR test are similar to other literatures and close to value described in WHO recommendations. PANBIOS® is a useful test for controlling the spread of COVID-19 allowing identification of active infection.
