Dr. Anthony Fauci, the former head of the National Institute of Allergy and Infectious Diseases, recently revealed that he is recovering from West Nile virus (WNV) at the age of 83. He was hospitalized for six days but is now recuperating at home.
A full recovery is expected, according to his spokesperson. This incident has brought attention to the West Nile virus, a mosquito-borne infectious disease first identified in Uganda in 1937 and later detected in the United States in 1999.
West Nile virus is primarily spread through the bite of infected Culex mosquitoes, which can transmit the virus to humans, birds, horses, and other mammals. Infected birds and horses can become viremic, carrying the virus in their blood, which can then be passed to other mosquitoes that feed on them.
Most human infections occur during late summer, with a peak in August and September. While the virus is not generally contagious between humans, it can be transmitted in rare cases through blood transfusions, organ transplants, and from mother to child during pregnancy, delivery, or breastfeeding.

In most cases, West Nile virus is asymptomatic, but about 20 percent of infected individuals develop symptoms such as fever, chills, headache, body aches, rash, vomiting, and diarrhea. Symptoms typically appear three to fourteen days after being bitten by an infected mosquito.
In rare cases, about 1 in 150, the virus can lead to severe neurological complications like meningitis and paralysis, with approximately one in ten of these severe cases resulting in death. The risk of serious complications increases with age and is higher in individuals with underlying health conditions.
There is currently no specific treatment or vaccine for West Nile virus, making prevention the best course of action. The Centers for Disease Control and Prevention (CDC) recommends using mosquito repellents containing DEET, wearing loose-fitting clothing that covers the arms and legs, using air conditioning or ensuring windows and doors have screens, and eliminating standing water where mosquitoes can breed. These measures are essential in reducing the risk of infection, especially during peak mosquito season.
West Nile virus has been a significant concern in the United States, particularly in New York City, where mosquitoes carrying the virus have been found in all five boroughs. In 2021, NYC experienced a severe mosquito season, with West Nile virus cases tripling compared to previous years.
While the number of deaths from the virus in the city remains relatively low, with only 18 fatalities since the first known case, the virus continues to pose a threat, especially to vulnerable populations such as the elderly and those with preexisting health conditions.
