Insights into the monkeypox virus: Making of another pandemic within the pandemic?

Just when the world started to adapt to the 'new normal' amid the coronavirus disease 19 (COVID-19) pandemic, the world is witnessing the wrath of another viral disease, the monkeypox virus (MPXV). The virus is endemic to African countries, where several outbreaks have been reported in the past. However, the present cases have been reported in non-endemic countries worldwide. Although MPX is considered to be a self-limiting disease, recent reports on its incidence have proved otherwise. The 2022 multi-country MPX outbreak has drawn the attention of global surveillance organizations and epidemiologists to trace its origin; however, there are existing gaps regarding the animal reservoirs, biological implications, and management of MPX. In view of the recent events, the World Health Organization (WHO) has also declared the ongoing MPX outbreak a global health emergency. Hence, the geographically expanding MPXV poses a significant threat to human health and public safety. In this review, the latest insights into the biology of MPXV have been provided by discussing its biological implications on human health, changing epidemiological footprint, and presently available intervention strategies. This review also sheds light on the existing lacunas and possible reasons that may have been responsible for the ongoing MPX outbreak.

While the world is still grappling with the COVID-19 pandemic, another viral disease, monkeypox, has emerged as a global threat. Monkeypox, previously limited to African countries, has now spread to non-endemic regions. The recent outbreak has raised concerns about the origins, biological implications, and management of the disease.
