In North America since 1999, West Nile Virus  (WNV) has joined the other major viruses like  dengue that cause various encephalites. WNV as  new is clinically little known and its role in public  health (PH), epidemiology, surveilance and vector  (mosquito) control is still illdefined. WNV is one  more PH cost. Costs range from hospital bed time  and clinical labor, loss of work hours and school  time to other costs like reagents for  immunological diagnosis. Birds (especially  crows), horses and man are the most noteworthy  in a very wide range of WNV hosts. During 1999- 2002, WNV was detected  in 36 mosquito species  in the US.

WNV is a member of the family Flaviviridae which  seems very close to Togaviridae. Serologically, it  is a member of the Japanese encephalitis virus  antigenic complex, which includes St. Louis,  Japanese, Kunjin and Murray Valley encephalitis  viruses. WNV was first isolated in Uganda in 1937. The 2002 WNV epidemic and epizootic resulted in  reports of 4,156 reported human cases of this  disease (including 2,942 meningoencephalitis  cases and 284 deaths), 16,741 dead birds, 6,604  infected mosquito pools and 14,571 equine cases.

The central problem is morbidity  and mortality by encephalites in  man, domestic and wild animals  caused by different mosquito- borne viruses throughout the  Americas.

It is much more important to deal with the entire  group of encephalitis viruses and dengue than it  is to dwell on WNV. There  SHOULD  BE  much  better PH orientation to the geographies and  seasonalities of all these viruses from local to  continental levels. Medical and veterinary forces  need better mutual understanding and  interaction. Climate, vector control and  surveillance are often neglected topics. Cyclonic  winds have strong yet little known epidemiologic  effects. What is the risk of infection? Of what or  whom? By what !! ? What are the public sentiments ?

Somehow, there is a feeling of  professional NEGLECT. Neglect relates to  ignorance. Much of the public has been  hardened by its previous disease  experiences. In its turn, this relates to  POLITICAL WILL In the end or in many  situations, the public must DEMAND  PROTECTION in order to get it. Of course,  the public best understand the RISK so  that it will pay the taxes needed to reduce  the risk. Where do your tax dollars go ? If  you replied, “Into vector control,” that  would be a reasonably good joke.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
