The Human Monkeypox Virus and Host Immunity: Emerging Diagnostic and Therapeutic Challenges

Area of Science:

• Virology
• Epidemiology
• Immunology

Background:

• Human Monkeypox Virus (MPV) is a zoonotic orthopoxvirus with a history of outbreaks beyond Africa since the 1970s.
• First detected in the US in 2003, MPV poses a public health concern due to its potential for interspecies transmission and genetic variability.

Purpose of the Study:

• To provide a comprehensive overview of Human Monkeypox Virus (MPV).
• To examine the virus's genetic characteristics, immunological responses, diagnostic challenges, and therapeutic strategies.
• To highlight future directions for MPV research and public health management.

Main Methods:

• Literature review and analysis of existing research on MPV.
• Examination of genetic sequencing data to understand viral evolution.
• Review of immunological studies on innate and adaptive responses to MPXV.
• Analysis of diagnostic techniques and therapeutic interventions, including antivirals and vaccines.

Main Results:

• MPV is categorized into two distinct genetic clades with varying pathogenicity.
• Genetic mutations in MPXV are influenced by environmental factors.
• Diagnostic challenges arise from MPXV's similarity to other orthopoxviruses, though molecular diagnostics show progress.
• Antiviral tecovirimat and JYNNEOS vaccine demonstrate efficacy but face challenges in widespread application and outbreak management.

Conclusions:

• Effective management of MPV requires advanced research, global surveillance, and personalized treatment approaches.
• Continued monitoring and research are crucial to mitigate the public health impact of MPV.
• Understanding MPV's complex interactions with host immune systems is key to developing better interventions.
