Chronic hepatitis C (HCV) infection affects 58 million people and is a significant cause of morbidity and mortality worldwide. HCV reinfection is a growing problem in people with risk factors such as heavy alcohol use, anal sex, group sex, and sharing needles and syringes. This type of infection is defined as a new HCV infection with a different viral genotype than the first infection in a patient after achieving a sustained viral response (SVR). Reinfection occurs, in part, due to the absence of promotion and prevention strategies. Taking this background into account, more pragmatic approaches have been proposed to control HCV infection and avoid reinfection, such as micro elimination.

This article reports the case of a patient with alterations in biochemical liver markers, for which a diagnostic test for HCV infection and then viral genotyping was requested. Infection by HCV genotype 1, subgenotype 1A, was evidenced. Management with direct-acting antivirals was started, and an adequate SVR12 was documented. Three months later, the patient returned, and the control tests showed a high HCV viral load, for which genotyping was requested, showing a new HCV genotype 4 infection.
