      Background Infection with SARS-CoV-2 can lead to a detectable serological immune response even though extent of its protection is still not yet well known. We report long duration and resurgence of SARS-CoV-2 in patients with COVID-19. Methods We included a cohort of 99 participants from our non-blinded non-randomized evaluation of COVID-19 tests in Cameroon. Demographic and clinical information was collected from participants including self-reported age, race, ethnicity, and gender. Qualitative data was described as proportions while quantitative data was described with means and accompanying ranges. Results Duration of PCR for SARS-CoV-2 positivity was found to range from 4 – 81 days, with mean duration of 32.8 days in patients with PCR-positive. We also identified 4 participants who also had SARS-CoV-2 resurgence within a three-month period. Conclusion These observations raise questions on clinical decision to release COVID-19 cases from isolation after 14 days.
