Summary of Dengue Issues In Sri Lanka Among Tourists
Russian travelers in Sri Lanka have faced rising dengue infections, drawing attention from medical researchers. Professor Pyotr Chumakov, Doctor of Biological Sciences and a senior investigator at the Engelhardt Institute of Molecular Biology, discussed dengue risks in a recent interview with 360 TV. He argued that vaccination against dengue may not be helpful and warned that the virus can have numerous side effects. His comments were shared to explain why travelers should rely on preventive measures rather than vaccines, and to remind Russians to use repellents during trips.
The scientist highlighted Sri Lanka as a natural hotspot for dengue transmission. He noted that mosquitoes spread the virus to humans through bites and urged travelers to remember this risk when visiting tropical regions. The key preventive measure he advocated is the use of effective skin repellents to minimize bites and reduce the chances of infection.
Chumakov also commented on the experience of dengue outbreaks, noting that while deaths have occurred, dengue fever is not inherently fatal in most cases. He mentioned that a vaccine for dengue exists but questioned its practical value for travelers. He explained that vaccination can trigger antibody production, which he believes may sometimes aid the virus rather than provide protection. This concept is linked to a phenomenon where antibody complexes can facilitate viral entry into cells, a process he described as antibody dependent enhancement. He warned that this could lead to a false sense of security and urged travelers to be cautious and not rely solely on vaccination for protection.
According to the professor, the virus can cause symptoms beyond fever, including potential cardiac and joint effects that warrant attention. He emphasized the importance of protective measures for anyone traveling to dengue-endemic areas, especially during peak transmission seasons. His remarks were aimed at raising awareness among travelers to take practical steps to reduce risk rather than assuming vaccination alone will guarantee safety.
Virologists have called attention to a growing dengue situation linked to international travel and tourism. The advice remains consistent: use mosquito repellents, wear long sleeves and pants when possible, and eliminate standing water where mosquitoes breed. The goal is to prevent bites rather than rely on vaccines that may not offer the expected level of protection for travelers.
There has been broader commentary on how climate factors influence dengue circulation. Analysts note that warmer temperatures can extend the breeding season for mosquitoes, potentially increasing exposure for visitors to affected regions. Public health organizations continue to monitor trends in dengue activity and update guidance for travelers accordingly to minimize risk. When planning travel to areas with dengue activity, individuals should consult official health advisories and consider preventive strategies that combine personal protection with environmental awareness. This approach helps reduce the chance of infection while avoiding overreliance on a single preventive measure.
In summary, the current message from experts stresses practical prevention, careful interpretation of vaccine information, and awareness of local transmission patterns. For travelers, the safest course remains diligent use of repellents, protective clothing, and avoidance of peak mosquito activity times, alongside staying informed through reputable health sources.

Further research and official guidance continue to shape recommendations for those visiting dengue-prone regions.n
