Jeonnam Province on Alert for SFTS as Asian Longhorned Tick Activity Intensifies

Jeonnam Province has urged residents to exercise extra caution during outdoor activities as the activity of the Asian longhorned tick, which transmits Severe Fever with Thrombocytopenia Syndrome (SFTS), is increasing with the rising spring temperatures.

SFTS is a highly fatal infectious disease for which there is currently no vaccine or treatment, making prevention the best response. In particular, high-risk group management has emerged as a key issue in Jeonnam, where agricultural work and outdoor activities are common.

According to statistics from the Korea Disease Control and Prevention Agency, since SFTS was designated a notifiable disease in 2013, a total of 2,345 cases have been reported nationwide through last year, with 422 deaths, resulting in a cumulative fatality rate of 18.0%. This year as well, one case each has been reported in Ulsan, Gangwon, and Gyeongnam.

In Jeonnam Province, there have been a total of 33 cases over the past three years, with 11 deaths. By year, there were 16 cases in 2023, 8 in 2024, and 9 in 2025. Although the number of cases has shown a downward trend, the high fatality rate remains a significant concern.

The Asian longhorned tick becomes active starting in April, with populations increasing in the summer and peaking in the fall. Symptoms such as high fever, vomiting, and diarrhea may develop within 5 to 14 days after infection.

Jeonnam Province is strengthening tick surveillance, particularly in areas like Gokseong, Boseong, and Yeongam, and is monitoring for pathogens in cooperation with the Jeonnam Institute of Health and Environment. The province also plans to expand preventive education and on-site campaigns targeting high-risk groups such as farmers and the elderly.

The disease control authorities emphasize that adherence to preventive measures is the most important response. They advise wearing long-sleeved shirts and long pants, using repellents during outdoor activities, and immediately showering and washing clothes after work. If a tick is found attached to the body or any suspicious symptoms develop, people are urged to seek medical attention immediately.
