In 1980, the World Health Organization declared smallpox eradicated from the world; the last known natural case had occurred in Somalia in 1977, and the United States had stopped routinely vaccinating its citizens in 1972. However, with increasing concerns regarding domestic and international terrorism, smallpox has resurfaced as a potential threat to global health. We review the direct and indirect modes of smallpox transmission and how patterns of transmission vary substantially, depending on the severity of circulating disease, vaccination status, environmental and socioeconomic factors, and the setting of an outbreak. We examine mechanisms for controlling outbreaks of disease and preventing further transmission in the event of an outbreak, with an emphasis on smallpox vaccination.

Monkeypox virus (MPXV) is an important zoonotic pathogenic virus, which poses serious threats to public health. MPXV infection can be prevented by immunization against the variola virus. Because of the safety risks and side effects of vaccination with live vaccinia virus (VACV) strain Tian Tan (VTT), we constructed two gene-deleted VTT recombinants (TTVAC7 and TTVC5).

Monkeypox (mpox) is a viral infection closely related to smallpox, manifesting as a milder febrile rash in affected individuals. Over the past two decades, the incidence of mpox has surged, possibly linked to a declining immunity against the smallpox vaccine worldwide. Recent outbreaks of mpox in multiple countries have sparked concerns regarding altered transmission patterns and the potential for a global menace.

The monkeypox virus (MPXV), which is a member of the Orthopoxvirus genus in the class Poxviridae, is the causative agent of the zoonotic viral infection MPXV. The disease is similar to smallpox, but it is usually less dangerous. This study examines the evolution of the MPXV epidemic in Canada with an emphasis on the effects of control employing actual data.

is a genus of over 50 species that are commonly used in primary care in several countries. This study seeks to inspire researchers to quickly discover and isolate the key active metabolites found in taxa, thereby promoting the development of novel, safe, and effective therapies for a variety of illnesses. To this end, we performed a thorough search of English-language publications from PubMed, Scopus, ScienceDirect, Web of Science, Google Scholar, and ResearchGate.
