Global Warming: Tropical Diseases Attack Europe – World

"Encouraged by climate change, travel and international trade, vector-borne epidemics [transmises par des insectes tels que les moustiques ou les tiques, ndlr] will be developed to reach large parts of Europe in the coming decades, "they point out at the Congress in Amsterdam.

All countries around the Mediterranean are already concerned, notes Giovanni Rezza, Director of Infectious Diseases at the Higher Institute of Health in Rome, interview with AFP.

400 cases of chikungunya in Italy

The most disturbing recent event is the chikungunya epidemic that hit Italy in the summer of 2017, with "over 400 cases" and "early diagnosis failure" because the disease was only a researcher found the government identified the government after a few weeks and favored new people.

This task of early identification in Italy is all the more difficult because tiger mosquito carrying dengue and chikungunya is now endemic in much of the country.

There is a need to strengthen vigilance where this phenomenon is still limited, for example, France with the Cote d'Azur, where several original dengue cases have been reported since 2014, is the case. Rezza, who presented his conclusions on these recent episodes. at the European Congress of Clinical Microbiology and Infectious Diseases, held in Amsterdam until Tuesday.

Fortunately, Italy, Spain, southern France, the Croatian coast and Greece are still "part-time tropical zones". Winter is cool enough to stop the transmission.

Mid-term change

But as the period of high temperatures increases, this "window", during which these diseases can be transmitted, spreads, favoring an epidemic of greater importance, warns Giovanni Rezza. It emphasizes that this is a "medium-term change, not a short-term change".

The work presented by Jan Semenza of the European Center for Disease Prevention and Control (ECDC), a European agency based in Stockholm, also testifies to the spread of ticks that is responsible for viral encephalitis and Lyme disease.

“We see the spread of ticks caused by higher temperatures. They are developing towards the north and at higher altitudes, "AFP said.

Similarly, a sand fly or sand fly, a major vector of parasitic leishmaniasis, could find favorable climatic conditions for its installation in France, Germany and the Southern United Kingdom by 2060.

Early warning systems

Faced with this phenomenon, "public health agencies need to improve supervision, for example through early warning systems, to raise the awareness of health professionals and the general public about risks and to adopt control strategies." "Community action" against the spread of mosquitoes, Professor Semenza emphasizes.

ECDC helps governments "model in real time where climate conditions contribute to transmission, so we can increase attention and monitoring in these areas," he says.

The European Center has developed a tool to monitor the temperature and content of seawater salt, illustrated by the map
( This allows you to identify the beaches that are most at risk from the presence of the vibrio family, responsible for sometimes severe human bowel disorders. (W / NXP)
