West Nile Virus
One of the most talked about and publicized viruses in the world today is the West Nile Virus. Named for the West Nile district of Uganda, West Nile Virus was first isolated in a woman in the West Nile district of Uganda in 1937 (World Health Organization, 2011). Although well known today, prior to 1999 the West Nile Virus was virtually unheard of in the United States. However, in New York City 1999 that changed when we had our first recognized case.

However, humans are not the only species that can fall victim to this disease. West Nile Virus has a broad host range and can infect humans, birds, mosquitoes, horses and some other mammals (Pommerville, 2014). The transmission cycle begins when mosquitoes feed on infected birds. It will then circulate through the mosquitoes’ blood supply and into the salivary glands afterwards the mosquito is capable of infecting others. In addition to mosquitoes, West Nile Virus has also been shown to be spread through blood and organ transfusions or exposure to blood in a laboratory or other …show more content…
The Centers for Disease Control and Prevention recommend using repellents containing DEET, picaridin, IR3535, and some oil of lemon eucalyptus and para-menthane-diol products provide longer-lasting protection. To optimize safety and effectiveness, repellents should be used according to the label instructions (Centers for Disease Control and Prevention [CDC], 2016).

Some ways of accomplishing this is by ensuring that there is no standing water or excessively large puddles around your yard.
