Oral and cutaneous manifestations of viral and bacterial infections: not only COVID-19

Abstract Globalization entails several medical problems, along with economic and social complications. Migrations from the other continents, increasing numbers of tourists world-wide, importation of foreign parasites, Aedes albopictus for example, have made diseases so far unknown in Europe a reality. The rapid spread of the COVID-19 pandemic throughout the world is a warning that other epidemics are still possible. Most, if not all of these diseases, transmitted by viruses or bacteria, present with cutaneous symptoms and signs that are highly important for a speedy diagnosis, a fundamental concept for arresting the diseases and saving lives. Dermatologists play a significant role in delineating cutaneous and mucosal lesions that are often lumped together as a rash. We provide a review of many of these cutaneous and mucosal lesions that sometimes are forgotten or even ignored.
