This is the time when the virus has begun spreading all throughout Europe, Asia, and the Americas. The main carrier of the virus is the mosquitoes. Since mosquitoes are small insects, it is hard to prevent them from spreading the virus.
Even though not all the cases are serious and not all are vulnerable to the disease, it may be fatal in various cases. In fact, there are about 280 people who died in the United States when there is West Nile virus outbreak in 2012. Not only that, there is no certain vaccine for the virus as well. Prevention is still the best protection for it.
There are about 80 % of people who are infected by the West Nile Virus that will not show any symptom. Furthermore, there is up to one percent of those who get infected by the virus become ill having the serious and potentially deadly complications.
The WNV or West Nile Virus used to exist only in some tropical and temperate area. However, in the year 1999, the infections suddenly appeared in New York. It is at this moment that it has already spread across almost all of the United States. Thus becoming a notifiable condition.
