A quiet spread of the dangerous tropical Dengue virus has been discovered on Croatia's popular island of Dugi Otok. The disease, typically associated with tropical regions, has been spreading into Europe due to climate change and invasive tiger mosquitoes. In May 2024, a German tourist who had visited Dugi Otok returned to Munich with symptoms of high fever and rash, and was diagnosed with Dengue. Since the tourist did not travel elsewhere during their holiday, they were likely infected in Croatia. This raised alarms among epidemiologists, leading to extensive field investigations. Testing of thirty residents from Dugi Otok, Verunić, Solin, and Božava revealed that eight individuals had antibodies against Dengue, indicating exposure to the virus. Only two reported symptoms such as fever and rash, while others showed no signs of illness. Silent transmission poses a significant risk for public health because it makes early detection and containment difficult. The Asian tiger mosquito, an invasive species first recorded in Croatia in 2004, is the main vector for Dengue. These mosquitoes are active during the day, increasing the risk of bites.

A popular Croatian island has revealed a quiet spread of a dangerous tropical virus, according to reports from local media. The disease, known as dengue, which was once confined to tropical regions, is now spreading into Europe due to climate change and invasive mosquito species. In May 2024, a German tourist who had returned from a vacation on the island of Dubrovnik in Croatia reported high fever and rashes upon arrival in Munich. A diagnosis confirmed the presence of dengue, a viral illness typically associated with tropical areas. Since the tourist had not traveled elsewhere during his stay, he was likely infected on the island. This discovery alarmed epidemiologists, as it marked the virus's return to the Adriatic after sixteen years. The tourist recalled seeing an unusual number of mosquitoes while staying at Marina Veli Rat, prompting epidemiologists to launch an extensive field investigation. The findings revealed that the tourist was not alone in being infected. Out of thirty residents tested in Velika Raca, Verunić, Solina, and Božava, eight had antibodies against the dengue virus, indicating recent or past exposure. Only two reported symptoms such as fever and rash, while the others were infected without awareness. The primary vector for dengue transmission is the Asian tiger mosquito, an invasive species first detected in Croatia near Zagreb in 2004. It has since spread along the coast, including to islands. Unlike native mosquitoes, which are most active at night, the tiger mosquito bites during the day, increasing the risk of infection. Climate change has played a key role in this spread. Warmer temperatures and longer summers create favorable conditions for the proliferation of the tiger mosquito, which has expanded its range to areas previously unsuitable for its survival. Cities such as Zagreb, Vienna, and Paris have become increasingly hospitable to its establishment. Studies indicate that May and June 2024 were significantly warmer than the long-term average in the Zadar region, accelerating the early start of the mosquito season. Experts also consider the possibility that the virus reached the island via Italian fishermen, given that the nearby Marche region simultaneously recorded a significant outbreak of dengue. Another concern is chikungunya, another tropical virus transmitted by the same mosquito. Once limited to Africa and Asia, it has begun spreading globally. Named after a Swahili word meaning “bending over,” the disease causes severe joint pain and other debilitating symptoms. While dengue is currently the focus, chikungunya poses a growing threat to public health in Europe. Symptoms of chikungunya develop rapidly, within two to twelve days following a bite from an infected mosquito. They begin with high fever, often exceeding 39 degrees Celsius, followed by intense joint pain, particularly in smaller joints such as fingers, wrists, and ankles. The pain can be so severe that movement becomes impossible. Other common symptoms include headaches, muscle pain, fatigue, skin rashes, and swelling in the limbs. There is no specific treatment for chikungunya, and management focuses on alleviating symptoms through rest, hydration, and medication to reduce fever and pain. Prevention remains critical, involving measures such as wearing long sleeves, using repellents, and installing protective screens on windows and doors.

A recent investigation on Dugi Otok has revealed the silent spread of the dengue virus among locals, raising concerns about health risks in Croatia. Experts warn of two dangerous viruses transmitted by mosquitoes, dengue and chikungunya, which could threaten residents' health due to warmer summers creating favorable conditions for their spread. The outbreak began in May 2024 when a German tourist returned from Dugi Otok with fever and rashes, later confirmed as dengue. Health authorities conducted extensive testing, finding eight individuals with antibodies indicating past or recent infection, though only two reported symptoms. This asymptomatic transmission poses challenges for early detection and disease control. Dengue spreads through the invasive Asian tiger mosquito, which thrives in warmer climates and bites during the day. Climate change and rising temperatures contribute to the expansion of these mosquitoes across Europe. While dengue cases were previously linked to tropical regions, they now appear in parts of Europe, including Croatia. Authorities also caution about chikungunya, which has not yet been recorded in Croatia but remains a potential threat.
