The Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing, Rospotrebnadzor, has released updated epidemiological data concerning the health of citizens returning from international travel. As of June 25, 2026, a total of 127 cases of dengue fever have been laboratory-confirmed among tourists arriving in the Russian Federation. Despite the seasonal increase in international departures, health officials state that there are no current prerequisites for the local transmission of the virus within the country.
Statistical Overview and Global Trends
Current statistics indicate a significant concentration of cases within the first half of the year compared to previous periods. While 178 cases were recorded throughout the entire year of 2025, the 127 cases detected in less than six months of 2026 suggest a rising trend in imported tropical infections. Experts attribute this increase to a resurgence in tourism to tropical and subtropical regions.
- Asia: Remains the primary source of imported cases, particularly from popular destinations in Southeast Asia.
- Latin America and the Caribbean: Nations such as Brazil and Thailand continue to report high vector activity.
- Africa: Seasonal outbreaks have contributed to the risk profile for international visitors.
Prevention and Epidemiological Monitoring
Rospotrebnadzor continues to conduct sanitary and quarantine control at border crossing points, utilizing the "Perimeter" automated system to identify individuals with signs of infectious diseases. Dengue fever is a viral infection transmitted to humans through the bite of infected Aedes aegypti and Aedes albopictus mosquitoes.
Rospotrebnadzor continues to monitor the epidemiological situation. There are no preconditions for the spread of the infection within the country.
To mitigate the risk of infection, travelers are advised to utilize individual protection measures. This includes the application of insect repellents, wearing long-sleeved clothing, and ensuring that accommodation facilities are equipped with window screens or mosquito netting.
Travelers returning from regions with high transmission rates should monitor their health closely for 14 days. Symptoms of the disease typically include high fever, severe headache, pain behind the eyes, and muscle or joint aches. If these symptoms occur, it is imperative to seek medical attention immediately and inform health professionals of recent international travel history to ensure accurate diagnosis and treatment.
