Mosquito survey triggered by concerns of carrying diseases

A SURVEY of mosquito populations is set to take place, as climate change has seen disease-carrying insects expand their territories northwards.

The Asian tiger mosquito, which can transmit numerous illnesses, including dengue fever, chikungunya and zika, has been recorded as near as northern France this summer.

‘This has resulted in recent increases in the number of cases of dengue fever in France that were not associated with travel,’ said a spokeswoman for the States.

‘As the winters become more temperate, we should expect to see more vector borne diseases, such as Congo Crimean haemorrhagic fever and dengue fever, which were previously confined to more tropical climates.’

More than 60 cases of dengue were recorded in southern France last year, compared with just a couple the year before.

The mosquito established as far north as Loire and Paris, according to a European Centre for Disease Prevention and Control report.

‘The risk to islanders remains low. However, we encourage everyone to stay informed, take necessary precautions when travelling, and promptly report any concerning symptoms to healthcare professionals.’

While the insect has not been recorded locally, Guernsey has been prepared.

‘As part of our preparedness plans, the environmental health team and States Analytical Laboratory are collaborating to survey the mosquito populations on the islands,’ said the spokeswoman.

‘This proactive approach will help us monitor any potential establishment of the Asian tiger mosquito in Guernsey, and take appropriate measures if needed.’

Public Health asked doctors to be vigilant about the symptoms of dengue fever and chikungunya, given the proximity and travel connections between the island and regions where the Asian tiger mosquito is established.

The mosquito is established throughout the Balkans, Greece, Italy, mid-Germany and eastern Spain, as well as southern and mid-France.

‘While the Asian tiger mosquito has not been reported to have established itself as far north as Guernsey, it is possible for islanders to encounter these mosquitoes when travelling to France and southern Europe.’

It recommended taking precautionary measures.

In the last three years, there have been no reported cases of Dengue, chikungunya or West Nile acquired in Guernsey.

All are notifiable diseases, and any cases acquired abroad or locally are required to be reported to the appropriate authorities for monitoring and control purposes.
