Eradication of mosquitoes and ticks would have no effect on the epidemic of which disease?

The correct answer, indicating that the eradication of mosquitoes and ticks would have no effect on the epidemic of infectious hepatitis, is supported by understanding the transmission pathways of these diseases. Infectious hepatitis, also known as hepatitis A, is primarily transmitted through the fecal-oral route, which means that it spreads through contaminated food and water rather than through vectors like mosquitoes or ticks.

In contrast, equine encephalitis, yellow fever, and Rocky Mountain spotted fever are all diseases that rely on a specific vector for their transmission. Equine encephalitis viruses are transmitted through mosquito bites, yellow fever is transmitted by mosquito vectors, and Rocky Mountain spotted fever is transmitted through ticks. Therefore, controlling or eradicating these vectors would directly impact the incidence and spread of these diseases.

Understanding the modes of transmission is crucial for effective public health measures. In this case, a focus on vector control is essential for preventing diseases like equine encephalitis, yellow fever, and Rocky Mountain spotted fever, but not for infectious hepatitis, which requires different prevention strategies such as improving sanitation and hygiene practices.
