What is the prevalence of West Nile Virus?

How many people does West Nile Virus affect? Does it have the same prevalence in men and women? And in the different countries?


The prevalence of West Nile Virus varies depending on the geographical location and climate conditions. West Nile Virus is primarily transmitted through infected mosquitoes to humans, birds, and other animals. It was first identified in Uganda in 1937 and has since spread to many parts of the world, including North America, Europe, the Middle East, and Africa.


In the United States, the Centers for Disease Control and Prevention (CDC) reports that West Nile Virus is endemic in all 48 contiguous states. The number of reported cases fluctuates from year to year, with peak activity occurring during the summer and early fall.


Globally, the World Health Organization (WHO) estimates that there are tens of thousands of cases of West Nile Virus infection each year. However, many cases go unreported or undiagnosed, making it challenging to determine the exact prevalence.


It is important to note that not everyone infected with West Nile Virus develops symptoms. Most people who become infected experience mild symptoms such as fever, headache, body aches, and fatigue. However, in rare cases, severe neurological complications can occur, leading to long-term health issues or even death.


Prevention measures such as using mosquito repellents, wearing protective clothing, and eliminating mosquito breeding sites are crucial in reducing the risk of West Nile Virus transmission.

There are lots of people every year that are infected. The difference between them and those of us who get infected are the immune system. The healthy immune system can fight the virus. These folks may feel bad for a day or so and then they are better. We who are infected have a weak immune system. The virus is not prejudice. If the person has a special blood type, they eat you up as they love it. Also has something to do with the carbon dioxide you breath out that they like.
