Invasive mosquitoes in the non-endemic German region of Saarland: What does the public know and how does it respond?
Public awareness of invasive mosquitoes is high, but actual preventive behaviors are lacking, highlighting the need for targeted education campaigns.
Where it sits
this study against the rest of the ara 290 corpusSummary and findings
This study assessed public awareness and preventive behavior regarding invasive mosquito species in Saarland, Germany. A total of 1064 respondents completed a questionnaire, with 623 (58.6%) meeting the inclusion criteria. Findings indicated a gap between awareness of preventive measures and actual practices.
Abstract
By assessing public awareness, preventive behavior, and knowledge regarding invasive mosquito species in Saarland, Germany, a non-endemic region at increasing invasion risk, this study aimed to explore how the introduction of invasive mosquitoes can be addressed in non-endemic areas. A population-based anonymous questionnaire in Saarland was conducted from February to June 2024. Participants were recruited through broad public dissemination using digital and analog approaches. Nine items assessed mosquito protection practices, knowledge of invasive species, and potential for pathogen transmission. Among 1064 respondents, 623 (58.6%) met the inclusion criteria. While over half of them recognized stagnant water removal as an effective preventive measure, fewer than one fifth practiced it regularly. Travel medicine consultations were associated with greater use of protective clothing. Among participants aged 26-35, men were more likely than women to report no prior engagement with mosquito prevention measures. Although most participants had heard of <i>Aedes albopictus</i>, fewer than half linked it to chikungunya transmission. Marked discrepancies persist between general awareness and evidence-based preventive behavior. Targeted seasonal education campaigns represent a modifiable lever to delay vector establishment and improve outbreak preparedness.
Background
This paper addresses public awareness and preventive behaviors concerning invasive mosquito species in a non-endemic region, Saarland, Germany. Prior research has indicated that invasive species can pose significant health risks, yet public knowledge and response may vary. Understanding these dynamics is crucial for developing effective public health strategies.
Methods
A population-based anonymous questionnaire was conducted from February to June 2024, with participants recruited through digital and analog methods. The study included 1064 respondents, of whom 623 met the inclusion criteria. The questionnaire assessed mosquito protection practices, knowledge of invasive species, and potential for pathogen transmission.
Results
Among the 623 respondents, over half recognized stagnant water removal as an effective preventive measure, but fewer than one fifth practiced it regularly. Travel medicine consultations were linked to greater use of protective clothing. Notably, men aged 26-35 reported less engagement with mosquito prevention measures compared to women.
Interpretation
The findings suggest a significant gap between awareness and actual preventive behaviors, which aligns with previous studies indicating that knowledge does not always translate into action. While the statistical significance of the findings is clear, the clinical relevance may be limited due to the low rates of actual preventive practices. Confounding factors include reliance on self-reported data and potential biases in participant selection.
Key findings
- 58.6% of respondents met the inclusion criteria, n=1064.
- Fewer than one fifth of participants practiced stagnant water removal regularly.
- Men aged 26-35 were more likely than women to report no prior engagement with mosquito prevention measures.
- Most participants had heard of Aedes albopictus, but fewer than half linked it to chikungunya transmission.
Limitations
- Self-reported data may not accurately reflect actual behaviors.
- Sample may not be representative of the entire population in Saarland.
