Variola virus is an anthroponotic agent that belongs to the orthopoxvirus family. It is an etiological agent of smallpox, an ancient disease that caused massive mortality of human populations. Twentieth century has witnessed the death of about 300 million people due to the unavailability of an effective vaccine. Early detection is the primary strategy to prevent an outbreak of smallpox. Variola virus forms the characteristic pus-filled pustules and centrifugal rash distribution in the infected patients while transmission occurs mainly through respiratory droplets during the early stage of infection. No antiviral drugs are approved for variola virus till date. Generation of first-generation vaccines helped in the eradication of smallpox which was declared by the World Health Organization.

Monkeypox virus (MPXV) is an enclosed, double-stranded DNA virus from the Orthopoxvirus genus, which also contains variola, vaccinia, and cowpox. MPXV, which was once confined to West and Central Africa, has recently had a rebound, spreading beyond its original range since 2017. The virus is distinguished by its unique morphology, which includes an oval or brick-shaped structure and a complex lipid and protein makeup.

Monkeypox (MPOX) is a zoonotic viral disease caused by the Monkeypox virus (MPXV), which has become the most significant public health threat within the genus since the eradication of the Variola virus (VARV). Despite the extensive attention MPXV has garnered, little is known about its clinical manifestations in humans. In this study, a high-throughput RNA sequencing (RNA-seq) and liquid chromatography-tandem mass spectrometry (LC-MS/MS) approach was employed to investigate the transcriptional and metabolic responses of HEK293T cells to the MPXV A5L protein.

The eradication of smallpox, a historic triumph in global public health, was accomplished without a complete conception of the mechanisms underlying vaccine-induced protection. Contemporary concerns regarding potential bioterrorism threats and the possibility of smallpox reemergence have spurred research efforts toward developing third-generation vaccines capable of effectively neutralizing the variola virus. Clinical trials for a third-generation smallpox vaccine (KVAC103) are underway to obtain licensure.

Poxviruses represent evolutionary successful infectious agents. As a family, poxviruses can infect a wide variety of species including humans, fish, and insects. While many other viruses are species-specific, an individual poxvirus species is often capable of infecting diverse hosts and cell types.
