West Nile Virus in the United States

West Nile Virus (WNV) is a single-chain flavivirus, mainly found in the eastern hemisphere, and it is possible to infect humans, birds, horses, mosquitoes and other livestock and wild animals. Since the first discovery in Uganda, West Nile province in 1937, I have plagued the world (Sally Murray). According to the South Carolina State Health and Environment Administration (SCDHEC), the disease is "Africa ... Europe, Middle East, West Asia, Central Asia ... America ... Founded in Canada, it is now Central America.

The continuing expansion of the West Nile virus in the United States shows that it was permanently established in the Western hemisphere. It causes disease and death in humans, wildlife, livestock, especially birds and horses. In humans, especially those over the age of 50, it causes diseases like influenza that can lead to aseptic meningitis, encephalitis, and death. How are birds and horses affected? Birds are natural reservoirs of West Nile virus. When a mosquito bites an infected bird and the virus spreads to the mosquito it can become a host. When the same mosquito bites a human, disease may be transmitted to human beings. Please note that this cycle may be the first sign of the West Nile virus in areas with dead birds.

West Nile virus is most commonly infected by mosquitoes. Mosquitoes are infected by chewing birds carrying viruses. As infected mosquito bites them, people can get West Nile virus. This happens most frequently during the warm seasons of spring, summer, early autumn. You can not get the West Nile virus from other people or your pet. Your doctor will take a physical exam and ask for your symptoms. He or she wants to know if you have recently been stabbed. They can then order blood tests to see if you have a West Nile virus. From time to time your doctor may order spinal checks to check for viruses. This involves collecting liquid samples from the spinal cord and around the brain. If you have severe symptoms, you may be asked for CT scan or MRI to look for inflammation in the brain.
