Monkeypox was identified for the first time in captive monkeys in 1958, and later was identified in humans in 1970; this was a smallpox-like disease that was eradicated in 1980 and is considered a re-emerging infection disease. From being a zoonotic disease related to the habitat of its probable reservoirs in endemic countries of West and Central Africa, in may 2022, its spread was reported in non-endemic countries without any history of travel to Africa, predominantly affecting males with sexual behaviors risk (homosexuals, bisexuals and men who have sex with men). It should be implemented strategies aimed at reducing the contact rate and the reduction of susceptible subjects through specific vaccination.

La influenza es una enfermedad respiratoria aguda causada por la infección de un grupo de agentes virales conocidos como virus de la influenza A, B y C (VI-A, VI-B y VI-C), los cuales pueden afectar tanto al hombre como a diversas especies animales, entre ellas aves, cerdos, caballos y otros mamíferos. En los seres humanos, la influenza humana (IH) suele presentarse periódicamente a intervalos aproximados de entre 6 y 12 meses, generando brotes o epidemias estacionarias. Sin embargo, la IH también puede presentarse bajo la forma de pandemia, en la que las tasas de morbimortalidad suelen ser extremadamente elevadas.

Influenza is a highly contagious disease. There are some historical descriptions of this condition by ancient Greek physicians, and the etiological agents have been known only for the last eight decades. The causative agent is the influenza virus, which has three main types: A, B, and C. Type A is capable of circulating within many different biological reservoirs, including humans, swine, and birds. It also has high genetic variability, which allows it to have minor antigenic drifts or mutations which are responsible of epidemics in humans. Sometimes changes are quite marked, leading to pandemics.In a globalized world, with more than 6 billion inhabitants, with many social inequities and evident climate changes, influenza viruses are a permanent risk for mankind.Clinical features for the different viral subtypes may vary from subtle infections to full blown and severe, life-threatening f...
