1,347 cases of dengue fever registered in france since may 1

MOST CAME FROM OVERSEAS BUT THE NUMBER OF NATIVE CASES IS RISING SHARPLY TOO, THE FRENCH HEALTH AUTHORITY HAS WARNED More than 1,300 cases of dengue fever have been reported in mainland

France since May this year, figures show, as their vector - tiger mosquitoes - continue to spread due to climate change. Most cases were in people who had returned from travelling to at-risk

areas, such as Southeast Asia or the Caribbean, including the French overseas territories. However, 36 cases were reported as ‘native’ during the surveillance period. This (termed

‘autochtone’ in French) means that they were found in people who had not travelled to an at-risk area, and had become infected by a tiger mosquito bite in France. NATIVE CASE AREAS The

native cases were identified in Provence-Alpes-Côte d’Azur, Occitanie, Auvergne Rhône-Alpes, and Île-de-France. They were identified during the surveillance period of May 1 and October 20,

said French health authority Santé Publique France (SPF) on October 24. IN THE PROVENCE-ALPES-CÔTE D'AZUR REGION: * Four cases detected in Gardanne (Bouches-du-Rhône) * One case “that

may have originated in Nice in the Alpes-Maritimes department or in Le Castellet or La Garde in the Var department”, said SPF * Nine cases in Boulbon (Bouches-du-Rhône) IN THE OCCITANIE

REGION: IN THE AUVERGNE-RHÔNE-ALPES: IN THE ÎLE-DE-FRANCE REGION: MOSQUITOES ON THE MOVE Most cases of dengue are seen in the southern regions of France, as the tiger mosquito is more common

there (and spreads more easily in warmer environments). In 2022, there were 66 native cases of dengue identified in France, mainly in Provence-Alpes-Côte-d'Azur and in Occitanie. SPF

has termed this ‘exceptional’, as it was more than the total number of cases - 48 - seen between 2010-2021 combined. However, the case in Ile-de-France this year was the first identified in

that more northern region, and shows that the mosquitoes - and therefore the virus - may be spreading further north. READ MORE: FIRST CASE OF NATIVE DENGUE FEVER FROM TIGER MOSQUITO IN PARIS

AREA The insect has spread rapidly since it was first reported in France in 2004. HOW TO AVOID TIGER MOSQUITOES AND DENGUE Despite their ‘big cat’ name, tiger mosquitoes are just as tiny as

‘regular’ mosquitoes. However, they are silent, and are active during the day. The Aedes albopictus (tiger mosquito) develops mainly in urban areas. They lay their eggs in stagnant water,

such as in vases, saucers, used tyres, blocked gutters, or poorly-stored waste. While they can also lay eggs in natural tree hollows and certain plants (such as bamboo), breeding sites

created by humans are the most common, said SPF. Emptying your home and garden of any stagnant water is the best method to keep them away - but you can also deter them with typical

anti-mosquito products such as sprays, creams, candles, electric diffusers, and clothes with long sleeves and trousers. Dengue can cause a high fever, a headache, joint pain and digestive

problems. It can also cause rashes, and in very rare severe cases, can cause haemorrhage. It is typically not fatal; only 0.01% of patients die. If you suspect you may have dengue - either

after returning from a trip to an at-risk area, or after receiving a mosquito bite - you are advised to contact medical assistance immediately. All cases of dengue in France must be reported

and investigated. RELATED ARTICLES FIRST CASE OF NATIVE DENGUE FEVER FROM TIGER MOSQUITO IN PARIS AREA ALARM OVER MASSIVE RISE OF MOSQUITO-SPREAD DISEASES CAUGHT IN FRANCE TIGER MOSQUITOES:
