17. West Nile Virus
The animals that tend to be infected by the West Nile virus are horses and birds. Humans are susceptible to the disease as well. The West Nile virus is a flavivirus transmitted by the bite of mosquitoes. The mosquitoes typically acquire the virus from biting a bird. As the mosquitoes continue to bite more animals and humans, the virus is spread. Most people who are bitten by a mosquito carrying the West Nile virus do not have any symptoms. Some people will have aches, pains, vomiting, diarrhea, and a rash. In rare cases, people can develop meningitis or encephalitis which are both diseases that cause severe inflammation.
There is no treatment for the virus itself. Patients receive treatment for the symptoms it presents. These include painkillers for mild cases. Severe cases will require hospitalization. Use mosquito repellent and take precautions such as wearing gloves when handling dead birds to prevent the spread of the virus.
