10 West Nile Virus Symptoms
Symptom #6: Swollen Lymph Nodes
West Nile virus infection can cause swelling of the lymph nodes in the neck. However, this is not always a sign of West Nile virus. Infections by other viruses or bacteria can cause similar swelling.
In the West Nile virus, the swelling occurs as a result of the immune system’s response to the disease. Inflammation and swelling occur as white blood cells work to destroy the virus. As with other symptoms of the West Nile virus, swelling of the lymph nodes only occurs in some people. Sometimes the swelling is so pronounced that it can be seen on the neck.
