Mosquito Boom Across Germany: Higher Risk Coming
Anticipated surge of mosquitoes in Lower Saxony - Highest predicted mosquito populations in Lower Saxony region
Be prepared for a mosquito invasion this year in Lower Saxony. A representative from the State Health Authority spoke to the German Press Agency, predicting a robust mosquito population under the influence of the mild winter. According to the spokesperson, the warmer climate is giving mosquitoes a major upper hand.
Summers with excessive rainfall create prime breeding opportunities for mosquitoes in bodies of water and pooled rainwater. Common house mosquitoes (Culex pipiens) are expected to be particularly prevalent.
Fret not; most mosquito bites are merely irritating, with pathogen transmission being rare. Nevertheless, excessive scratching of bite sites can allow dirt and bacteria to enter, leading to inflammation. To protect yourself from bites, wear long clothing and regularly apply repellents. Additionally, empty and dry out potential breeding sites in your garden to minimize mosquito spread.
It's not just Lower Saxony under a dark cloud of mosquito fever. Warmer summers and altered rainfall patterns have pushed exotic mosquito species further north, spilling into the Federal States. For example, the tiger mosquito (Aedes albopictus) has been spotted in the region, though established populations are yet to be confirmed. While concerns over potential disease transmission are growing, as of now, no tropical pathogens have been identified in German tiger mosquito populations.
On a brighter note, the West Nile Virus (WNV) has had a minimal impact in Lower Saxony thus far. Infections have mainly occurred in eastern regions of Germany, but WNV was detected for the first time in Lower Saxony in humans and horses in 2024. Admittedly, the common house mosquito — the primary WNV transmitter— is nearly ubiquitous and cannot be manageably controlled for dissemination.
Around 80 percent of WNV infections in humans are symptom-free. However, severe cases with meningitis, encephalitis, or fatal complications in rare instances, particularly for the elderly, are a worrying trend. For horses, most infections are symptom-free, but some animals show acute neurological symptoms like paralysis, muscle tremors, and weakness. Consequently, vaccination is advised for horses in affected areas. Sadly, there is no available vaccine for humans at this time.

Insights: Climate Change Impact on Mosquitoes & Disease Transmission
- Climate change is facilitating mosquito population growth through milder winters, rising temperatures, and increased precipitation[1].
- Exotic mosquito species like the tiger mosquito may expand into new regions as climate patterns shift favorably[1].
- While WNV is coming under control in some regions, climate change could potentially amplify mosquito populations and intensify WNV transmission[2].

Insights: Landfill-Bred Mosquitoes
- Rising temperatures and changing precipitation patterns could promote mosquito reproduction in landfills, which may offer standing water as breeding sites[3].
- Controlling mosquito populations in landfills is crucial to prevent the spread of disease and infestation in nearby areas[4].

- The warmer climate due to climate change is providing an advantage to mosquitoes, aiding in their population growth.
- Exotic species like the tiger mosquito could be pushed further north by changing climate patterns, posing a potential threat to the EC countries.
- Climate change may intensify the West Nile Virus transmission, particularly in regions where the virus is already high, such as Lower Saxony.
