A specialist has raised concerns that the ongoing heatwave has created ideal conditions for a notable increase in mosquitoes.

These blood-sucking insects are already a common annoyance during summer, not only in foreign destinations but also in various parts of the UK, where over 30 native species exist. With the rise in temperatures becoming more frequent, experts caution that mosquitoes could become more active due to the acceleration of their life cycle.

The alert is prompted by worries that mosquito species capable of transmitting diseases like dengue fever and Zika could potentially establish themselves in the UK in the foreseeable future as the climate continues to warm.

Dr. Mojca Kristan, an assistant professor specializing in medical entomology at the London School of Hygiene and Tropical Medicine (LSHTM), highlighted that the current weather conditions in the UK are conducive for mosquitoes. These insects thrive in warmth and require stagnant water to lay their eggs.

Although invasive mosquito species that can spread viruses such as dengue fever, chikungunya, and Zika are not currently prevalent in the UK, Dr. Kristan noted that these diseases are already circulating in certain parts of Europe, particularly around the Mediterranean. Additionally, eggs from the Asian tiger mosquito (Aedes albopictus) have been discovered in the UK.

Modeling studies indicate that the climate in London and its surrounding areas may favor the endemic transmission of dengue fever by the 2060s, according to Dr. Kristan.

She emphasized the importance of staying vigilant against the potential threat of new disease-carrying mosquito species as climate change makes the UK a more hospitable environment for mosquitoes. Warm weather can expedite the hatching of mosquito eggs, and female mosquitoes require blood to aid in the development of their eggs.

To minimize the risk of mosquito bites, Dr. Kristan recommended the use of insect repellent, wearing long sleeves to cover the skin, and putting on socks in the evening, as mosquitoes tend to target the ankles for biting.

Dengue fever can manifest flu-like symptoms, while chikungunya may cause fever and intense joint pain. Although most individuals with Zika experience mild symptoms, the virus can pose significant risks during pregnancy, potentially leading to miscarriage, stillbirth, and birth defects.
