The SARS-CoV-2 is the causative agent of COVID-19, a disease that was declared a pandemic by the World Health Organization (WHO), at the beginning of 2020. Various authors have pointed out that morbidity and mortality as well as the economic consequences of a pandemic are influenced by factors such as the susceptibility of the population to infection, the severity of the disease, transmissibility and routes of transmission. It was of particular interest in this work to focus on the importance of the back of the hand during the transmission process of SARS- CoV- 2. The expression, as well as the functionality of the ACE2 receptors on the back of the hand was demonstrated by immune-histochemical techniques and the implications of these findings in the indirect transmission of the virus were discussed. We conclude that contact with the skin for example, through the fist salute, contributes to the increase in transmissions, in such a way that we suggest that this practice be avoided as a protection measure.
