Pathogenicity and virulence of chikungunya virus

Area of Science:

• Virology
• Immunology
• Epidemiology

Background:

• Chikungunya virus (CHIKV) is a mosquito-borne RNA virus causing debilitating musculoskeletal illness.
• CHIKV has re-emerged globally, leading to widespread outbreaks affecting millions.
• Despite extensive research, no curative treatment for CHIKV infection exists, with management focused on supportive care.

Purpose of the Study:

• To provide a comprehensive overview of CHIKV pathogenesis.
• To elucidate the complex interactions between viral genetics, host factors, immune responses, and vector-related elements.
• To contribute insights for developing effective prevention and management strategies against CHIKV.

Main Methods:

• This review synthesizes existing research on CHIKV.
• It examines viral genetics, host-pathogen interactions, and immune system responses.
• Vector-related factors influencing CHIKV transmission are also analyzed.

Main Results:

• CHIKV pathogenesis involves intricate interactions between viral and host elements.
• Understanding these mechanisms is key to disease control.
• Current knowledge highlights the need for improved therapeutic and preventative approaches.

Conclusions:

• A deeper understanding of CHIKV pathogenesis is critical for addressing this global health threat.
• Further research into viral genetics, host immunity, and vector biology is essential.
• This review provides a foundation for developing novel strategies against CHIKV infection.
