COVID-19 pandemic continues to spread across the world in late September 2020. To date, total cases of COVID-19 exceed 33 million including 996.342 deaths according to the WHO data. Although hydroxychloroquine, oseltamivir, remdesivir, favipiravir have been reported as an anti-SARS-CoV-2 effect, it is still unclear the fully effective protective drug and treatment. Herein, we report a woman under Tenofovir diphosphate who live and close contact with his COVID-19 positive husband. Although she had close contact with his husband without measure in the home she did not show any symptoms and signs of COVID-19 and her PCR test along with antibody test negative. Given the high reproduction number of SARS-CoV-2 and long-term close contact of the case, it can be speculated that Tenofovir could interfere with the transmission of COVID-19.
