A new case of dengue fever was confirmed in Bologna, Italy, on April 5, 2023, in the Lame district, prompting local authorities to implement targeted preventive measures, according to the Bologna City Council. The affected individual, whose movements were restricted to the area, has since been isolated, and the administration has initiated disinsection protocols to reduce mosquito populations, as outlined in the regional health protocol.
Preventive Measures in Bologna’s Lame Area

The city’s health department announced that adulticides will be applied in public spaces and private courtyards within the Lame district, including streets such as Via Lame, Via San Felice, and Via Marconi. Residents in the affected zones are being urged to cooperate with pest control teams, who will conduct larvicidal and adulticidal treatments in communal areas, according to a statement from Palazzo D’Accursio.
This follows a similar response to a dengue case reported in the Borgo Panigale neighborhood the previous week, where public and private areas were also treated with adulticides. The regional health protocol emphasizes collaboration between local authorities and residents to limit mosquito breeding sites, as dengue is transmitted by the Aedes aegypti mosquito, which thrives in urban environments.
Understanding Dengue: Symptoms and Treatment
Dengue is a viral infection typically characterized by a sudden high fever, severe headache, joint pain, and rash, according to the World Health Organization (WHO). While most cases resolve within a week, some may progress to more severe forms, such as dengue hemorrhagic fever, which can be life-threatening.
There is no specific antiviral treatment for dengue, and care focuses on managing symptoms, including hydration and pain relief. The WHO advises seeking medical attention if symptoms worsen, such as persistent vomiting, bleeding, or difficulty breathing.
Public Health Response and Community Engagement
Bologna’s health authorities have emphasized the importance of community participation in mosquito control. Residents are encouraged to eliminate standing water in gardens, balconies, and other outdoor spaces, as these serve as breeding grounds for mosquitoes. The city’s previous response to the Borgo Panigale case included similar calls for public cooperation, with officials noting that 90% of affected households complied with disinsection protocols.
Local health officials also reiterated that pest control teams do not enter private residences but may access courtyards and communal areas to apply treatments. Residents are advised to contact the city’s health department for updates or concerns.
Context: Dengue in Italy and Global Trends
Dengue cases in Italy have remained rare but have increased in recent years due to climate change and international travel. The European Centre for Disease Prevention and Control (ECDC) reported 172 laboratory-confirmed dengue cases in Italy in 2022, primarily linked to travel to endemic regions. However, local transmission, as seen in Bologna, highlights the growing risk of mosquito-borne diseases in southern Europe.
The ECDC recommends continued surveillance and public education to mitigate risks, particularly in areas with warming temperatures that extend mosquito activity seasons.
Residents in Bologna are advised to monitor for symptoms and report suspected cases to local health authorities. The city’s preventive measures aim to curb further spread, but ongoing vigilance remains critical in managing dengue risks.
