When two viruses collide: coronavirus disease after hepatitis B virus reactivation

Abstract

The COVID-19 pandemic has exploded since the first cases were reported in Wuhan in December 2019, engulfing the globe. Many infected individuals are asymptomatic or have a mild or moderate disease. A subset of people with advanced age, the immunocompromised and those with chronic diseases, are prone to serious-to-critical illness. We report a fatal case of metastatic colorectal cancer survivor who developed COVID-19 after clinically reactivated hepatitis B virus (HBV) due to chemotherapy. The patient’s COVID-19 illness was supposed to be related to her recent medical evaluation. Although being diagnosed with chronic HBV infection for decades, she was not treated with nucleotide analogue and the possibility to preclude HBV reactivation was missed. Moreover, infectious control practices must be draconian in order to save such a fragile population from infections.
