Mosquito-Borne Diseases (4)

Mosquitoes can transmit pathogens to pets and animals. The three mosquito-borne diseases found in our district, West Nile, St. Louis encephalitis, and Western equine encephalitis viruses, primarily circulate in birds. West Nile Virus and Western equine encephalitis virus can be transmitted to horses. However, there is a West Nile and Western equine encephalitis virus vaccine available for horses. Additionally, dogs can also be infected with dog heartworm, a mosquito-borne parasite.

The District tests mosquitoes collected within the District border using RNA extraction and reverse transcription real-time polymerase chain reaction (RT-PCR).

West Nile virus and St. Louis encephalitis virus have been detected in the District every year. Currently, the District tests mosquitoes for West Nile, St. Louis Encephalitis, and Western Equine Encephalitis viruses.

Mosquito-borne diseases are diseases caused by pathogens that are spread through the bite of an infected mosquito. These include malaria, yellow fever, Zika, West Nile virus, St. Louis encephalitis virus, Western equine encephalitis virus, dengue, chikungunya, dog heartworm, and many more.
