A Brief Report on Monkeypox Outbreak 2022: Historical Perspective and Disease Pathogenesis

Monkeypox is a zoonotic disease caused by the monkeypox virus (MPXV). It was an epidemic infection among African countries over the last few decades. In 2022, MPXV has been broke through in Africa, America, Eastern Mediterranean, Europe, South-East Asia, and Western Pacific region. This widespread infection of MPXV has created panic across the nations, and the WHO has declared a global public health emergency due to the multi-country MPX outbreak. We prepared this brief report on the MPX outbreak 2022 by extracting data from Scopus, PubMed, and website databases. We manually read all the relevant articles from our target databases. The rapid spread of MPX infection in around a 100 countries has threatened the global healthcare systems. The available epidemiological data revealed that sexual orientations and encounters are potential contributing factors for monkeypox infections. However, it has not been categorized as a sexually transmitted infection. Also, MPXV can transfer from 1 individual to others in many ways. The empowerment of this old foe has created additional pressure and threat on the healthcare authorities during the ongoing Covid-19 pandemic. Effective preventive measures, social awareness, and therapeutic approaches can reduce this extra burden on the healthcare system across the countries. Focusing only on sexual orientations and encounters as risk factors for MPX infection might increase stigma that will be another barrier to controlling and preventing MPXV spread. Therefore, we should be careful in delivering messages about MPX infection to the general population. Also, we recommend repositioning the existing smallpox vaccines and antivirals in MPX infection until the development of specific antiviral agents against this infection.
