News Summary

The South Carolina Department of Public Health confirmed the first death from eastern equine encephalitis (EEE) virus in Beaufort County in over 20 years.

The Beaufort County Mosquito Control is increasing control efforts following this rare human case. Public health officials emphasize the importance of mosquito bite prevention and awareness to protect community health.

Beaufort County Reports First Confirmed Death from EEE Virus in Over 20 Years

The South Carolina Department of Public Health (DPH) has announced the first confirmed death from eastern equine encephalitis (EEE) virus in more than 20 years. This death marks the first human case of EEE virus reported in South Carolina since 2020, with the state last experiencing a related fatality in 2003. The confirmed death occurred in Beaufort County.

The EEE virus is transmitted to humans through the bite of an infected mosquito. It is crucial to note that the virus is not contagious between humans. Individuals infected with EEE can either experience febrile illness without neurological symptoms or severe neurological diseases, such as encephalitis or meningitis. Approximately 30% of those with severe EEE infections die, and many survivors may experience long-term neurological problems.

Currently, there are no vaccines available to prevent EEE, nor are there effective treatments for infected humans. The DPH has acknowledged the rarity of human cases of the virus but has emphasized the serious effects they can have on those affected.

In response to the recent human case, the Beaufort County Mosquito Control has ramped up its efforts by conducting multiple truck spraying applications aimed at controlling the mosquito population in the area. Plans are in place for helicopter spraying to ensure broader coverage. Surveillance has revealed that the closest monitoring trap to the site of the human case was approximately 2.5 miles away, and thus far, no EEE-positive mosquitoes have been detected in 2025.

Since mid-July, Beaufort County has reported 10 EEE-positive horses across various counties, including Aiken (3), Colleton (2), and several others. The DPH is collaborating with the CDC to monitor mosquito-borne diseases through various surveillance methods, including trapping mosquitoes and testing local wildlife.

The public is encouraged to reduce the risk of mosquito bites by taking measures to eliminate potential mosquito breeding sites. Following the “7 Ts” guidelines is recommended to help minimize mosquito populations and protect community health.

Understanding Eastern Equine Encephalitis

Eastern equine encephalitis is a rare but serious viral infection. The virus is primarily found in parts of the United States and typically affects horses, although it can also infect humans. The presence of the virus in horses serves as a significant indicator of its potential threat to human populations.

Public Health Recommendations

The DPH advises residents to be vigilant in pest control and to be informed about the risks associated with mosquito bites. By taking preventive actions, individuals can help reduce the likelihood of contracting the virus.

Conclusion

The recent death from EEE in Beaufort County serves as a stark reminder of the potential dangers posed by mosquito-borne illnesses. Public health officials continue to emphasize the importance of awareness and prevention to safeguard community health.
