A Comprehensive Study on Chickenpox (VZV): Transmission Dynamics, Clinical Diagnosis, and Control Strategies

Abstract

Varicella-zoster virus (VZV), the causative agent of chickenpox, remains a significant infectious disease with notable public health implications. This study presents a comprehensive analysis of VZV focusing on its epidemiology, clinical characteristics, transmission dynamics, and vaccination impact. A secondary data-based approach is adopted, integrating findings from epidemiological studies, clinical reports, and mathematical modeling techniques. Numerical methods, particularly nonstandard finite difference schemes, are considered to analyze disease transmission and stability. The study highlights challenges in differential diagnosis, especially with diseases such as monkeypox, and emphasizes the importance of molecular diagnostic tools. Furthermore, the effectiveness and long-term implications of vaccination strategies are evaluated. The findings contribute to improved understanding of disease control, prevention strategies, and future research directions in infectious disease modeling and public health management.
