[EPIDEMIOLOGIC ANALYSIS OF OUTBREAKS OF DISEASES CAUSED BY AMERICAN EQUINE ENCEPHALITIS CAUSATIVE AGENTS IN ENDEMIC REGIONS].

This research article provides an analysis of disease outbreaks caused by certain agents, focusing on American equine encephalitis. These are diseases usually accompanied by fever and neurological symptoms, and represent an ongoing health issue due to the potential for lethal outcomes.

Etiologic Agents and Disease Overview

• The research focuses on incidence of diseases caused by American Equine Encephalitis, specifically Eastern equine encephalomyelitis (EEE), Western equine encephalomyelitis (WEE) and Venezuela equine encephalomyelitis (VEE).
• These diseases are largely transmitted by mosquitoes and are usually accompanied by symptoms of fever and neurological effects.
• Whilst all three are dangerous, the review identifies the VEE virus as presenting the most potential danger for humans and domestic animals.

VEE Virus Strains as Disease Agents

• The article points out that enzootic strains of VEE, particularly the subtype ID virus, are increasingly being implicated as agents of human disease in endemic regions during inter-epidemic periods.
• A key concern cited is the ability of these subtype ID strains to mutate into IC subtype, which could potentially lead to further epidemic outbreaks.

Threat Posed by EEE and WEE Viruses

• Despite having a lower incidence rate, diseases caused by the EEE and WEE viruses also pose a significant health problem.
• The review notes the relatively high rate of lethal outcomes associated with these diseases, which underscores their importance as a healthcare concern.

Conclusion

• This review underscores the need for ongoing vigilance and research into the diseases caused by the EEE, WEE and VEE viruses. Whilst they are most prevalently associated with equine species, their potential for human infection and lethal outcomes makes them a significant focus for public health.
