Describe the transmission of Eastern Equine Encephalitis and West Nile Fever in animals and write their symptoms.

Eastern Equine Encephalitis (EEE) and West Nile Fever (WNF) are two significant viral diseases in animals, primarily affecting horses and birds, respectively. Both diseases are transmitted by arthropods, but their epidemiology, transmission dynamics, and symptoms differ considerably. Here’s a comprehensive overview of each disease, focusing on their transmission routes and symptoms.

### Eastern Equine Encephalitis (EEE)

Transmission:
Eastern Equine Encephalitis is caused by the EEE virus, which is a member of the Alphavirus genus in the Togaviridae family. This virus is primarily transmitted through the bite of infected mosquitoes. Mosquitoes acquire the virus by feeding on the blood of infected birds, which act as the primary amplifying hosts. The virus then circulates in the mosquito population and can infect horses and, in rare cases, humans when bitten by these infected mosquitoes.

The transmission cycle involves several steps:
1. Birds as Reservoirs: Wild birds, especially those of the family Corvidae (e.g., crows and ravens), are the main reservoirs of the EEE virus. These birds can carry high viral loads in their bloodstream, which are _____ _______ ___ ______ _____ __________ _____.
