What is West Nile Virus? Is it dangerous like Coronavirus? Here's all you need to know

The West Nile virus, which is spread by mosquitoes, is gaining attention in the US as cases increase; Texas is reporting the largest number of cases. The virus recently forced Dr. Anthony Fauci, the former director of the National Institute of Allergy and Infectious Diseases, to spend six days in the hospital. He is now recuperating at home at the age of 83. Even though Dr. Fauci is a well-known public personality, it is still unknown where she got the infection, as per the reports of Daily Express US.

With 37 West Nile virus cases documented in the state of Texas in 2024, Texas tops the country in official data from the Centers for Disease Control and Prevention (CDC). Following with 23 cases, Nevada is followed by Nebraska with 20 verified cases. This year, 216 cases in all have been reported nationwide. Significant numbers are also being seen in Louisiana and Mississippi, with 19 and 18 cases, respectively.

High-Risk areas and preventive measures

While the total number of cases may not appear concerning, health officials are advising citizens in several states to exercise caution. Particularly in Massachusetts, a few high-risk communities have been identified. Dr. Catherine M. Brown, the state epidemiologist, underlined the need of donning protective gear and applying insect repellent with an EPA-registered active component. She also suggested removing water-collecting containers and inspecting window screens for gaps, since standing water can draw insects.


The first West Nile virus cases of the year were recorded in New York City by the Department of Health, and four patients were given treatment. Three of these people—who reside in Queens and Manhattan—were admitted to the hospital.

Understanding the virus's impact

There isn't a vaccine to protect against West Nile virus as of yet. The majority of viral infections do not cause any symptoms. Still, one in five people get fever and other symptoms, and one in 150 people may experience a serious, even fatal, illness. The virus was linked to 182 deaths and 1,800 hospital admissions in 2023, according to the CDC.
