Rock Hill Resident Diagnosed with West Nile Virus

In the city of Rock Hill, South Carolina, health officials are heightening efforts to manage the risk of the West Nile virus after a local resident was recently diagnosed. York County residents are being advised to exercise caution following the identification of this case.

The S.C. Department of Public Health disclosed details of the diagnosis to the York County Office of Emergency Management on August 23. Subsequently, the broader public was informed about the situation on August 24. This case signifies one of fewer than five incidents of the West Nile virus detected in South Carolina in the current year as per the data from state health officials. This marked the first case in Rock Hill in four years. The previous year experienced 19 confirmed West Nile virus cases.

How Does West Nile Virus Spread?

The leading cause of mosquito-borne disease in the United States, West Nile virus is predominantly spread through the bite of an infected mosquito. The mosquito season, which often sees cases of West Nile virus, kicks off in the summer and stretches through the fall. Unfortunately, we currently have no vaccine or specific antiviral treatments for West Nile virus infection.

Due to privacy laws, the Department of Public Health was unable to furnish any details regarding the condition of the individual from Rock Hill currently being treated for the virus. If the number of infections is fewer than five, such information is often kept confidential.

Prevention Tips

Preventive measures that the public can take include the elimination of areas of standing water, which serve as breeding grounds for mosquitoes, regular usage of insect repellant, wearing clothing that adequately covers the skin, and ensuring windows and doors remain closed to bar entry of these insects.

On August 26, county officials planned to carry out mosquito control by spraying within a 1-mile radius along Constitution Boulevard in Rock Hill. It’s a residential area situated north of Cherry Street. The spray product, Envion 4-4, used for these operations is deemed safe for humans, pets, other insects, and gardens. However, it is still advisable not to come directly under the path of the spray operations. Beekeepers within this 1-mile radius are recommended to cover their hives during the night of spraying.

The West Nile Virus Across the United States

As per the ArboNET division of the Centers for Disease Control and Prevention, as of August 20, there have been a total of 216 recorded human cases of West Nile virus infection across 31 states in the current year. This figure includes 142 severe neuroinvasive disease cases, where the virus makes its way to the brain. Most healthy individuals infected with the West Nile virus may not exhibit any symptoms. However, for others, it can lead to fever, body ache, nausea, or vomiting. Tragically, 1 in 150 infected individuals develop neuroinvasive disease, impacting the brain or central nervous system. Approximately 10% of these patients tragically lose their life to the virus.

Since the initial documentation of the virus in 1999, South Carolina has registered 145 human West Nile virus cases in total. This reminds us of the importance of preventive measures and preparedness as we continue to combat this public health issue.
