Abstract

This study is aimed at determining the real time reverse transcriptase polymerase chain reaction (RT-PCR) time to negative conversion among COVID-19 patients in the isolation camps in northeast Nigeria. All patients who were confirmed COVID positive from February 2020 till January 2021 were considered for this study. All patients were tested using RT-PCR. COVID-19 was confirmed by detecting SARS-CoV-2 RNA in throat swab samples. A total of 319 patients that met the criteria were used for this study, data for repeat RT-PCR was obtained from the patient’s records. Of thee 319 patients there were more patients between the ages of 16-30 and 31 to 45 which represent 90 (28%) and 79 (24.8) respectively. History of recent travels within 14 days before diagnoses was the highest identifiable risk factor among the study population 169 (46.9). Symptoms of Fever 81 (19.9%), cough 77 (18.9%) and sore throat 40 (9.8%) were among the commonest presenting symptoms, while other symptoms like Sneezing, sputum, rhinorrhea, diarrhoea, Anosmia, vomiting and ageusia were also seen at varying frequencies. There were 22% of cases with co-morbidity, the most common among which were hypertension 43 (60.6%), diabetes 16 (22.5%), chronic kidney disease 4 (5.6%), heart failure 3 (4.2%), Ischemic heart disease 2 (2.8%) and chronic diseases 3 (4.2%). Within 3 weeks of isolation 86.2% of patients had negative RT-PCR repeat test and 306 (96%) had their symptoms resolved and a negative repeat RT-PCR at the end of the 6 weeks isolation period. There were 4.1% (13) mortality (p=0.001). In conclusion we found a median 2 weeks (14 days) period of negative conversion among affected patients, old age, presence of co- morbid conditions and sex are identifiable risks for delayed conversion and mortality among patients. Most patients converted within the first 3 weeks of isolation and prompt management. Therefore early presentation, prompt management and close monitoring of patients, that are aged and or with co-morbidities is paramount in reducing morbidity and mortality among SARS CoV 2 patients.
