Numerous cases of \u00a0dengue\u00a0 (which is actively circulating overseas), as well as \u2014 more exceptionally \u2014 \u00a0chikungunya\u00a0 (due to an \u00a0unprecedented epidemic in R\u00e9union\u00a0, which has recorded fatalities) have emerged since early May in Haute-Garonne. What is the scale of this phenomenon? Which areas are the most affected? Here\u2019s what the latest numbers reveal as of Thursday, June 5, 2025.<\/p>\n<h2 class=\"wall-content\">Haute-Garonne: 39 Cases of Tropical Diseases in One Month, Compared to 4 Last Year<\/h2>\n<p>According to official data from health authorities released on June 5, 2025, the onset of this season has been \u00a0explosive\u00a0 in the department. In \u00a0one month\u00a0, from May 1 to June 3, 2025, there have been \u00a039 cases of tropical diseases\u00a0 reported in Haute-Garonne (18 cases of dengue and 21 of chikungunya), making it the most affected department in the region, with nearly half of all cases in Occitanie.<\/p>\n<p>So far, these are \u00a0only imported cases\u00a0, originating from individuals who traveled abroad, mainly to overseas territories, where they were infected.<\/p>\n<p>To prevent any \u00a0local transmission\u00a0 (where individuals fall ill without having traveled to an infected area), \u00a044 entomological surveys\u00a0 have been conducted by Altopictus. According to Public Health France, \u00a010 anti-vector control treatments\u00a0 have been carried out in one month \u201cin the vicinity of the cases.\u201d<\/p>\n<p>These impressive figures are even more striking when considering that in \u00a0May 2024\u00a0, only four cases of dengue (and zero cases of chikungunya) were documented\u2026<\/p>\n<h2 class=\"wall-content\">\u201cWe\u2019ve Never Had This Much Work\u201d in Mosquito Control<\/h2>\n<p>\u201cThis is a record-breaking May,\u201d confirms \u00a0Renaud Chevalier\u00a0, the technical manager at \u00a0Altopictus\u00a0 in Haute-Garonne. \u201cWe\u2019ve never had so much work at the start of the season\u2026\u201d. Among the 90 entomological investigations performed by his company across the 13 departments of Occitanie, he indicates that around \u00a040\u00a0 were conducted in Haute-Garonne.<\/p>\n<p>His company, which has its departmental office based in Muret, is indeed responsible for all \u00a0anti-vector operations\u00a0 (including \u00a0mosquito control campaigns\u00a0) mandated by the ARS (Regional Health Agency). They only perform these operations upon request from the ARS and after confirmed cases of tropical diseases.<\/p>\n<div class=\"ac-article-push wall-content\">\n<div class=\"ac-article-push__content\">\n<h3>How are authorities fighting these diseases?<\/h3>\n<p>As the ARS Occitanie reminds us, chikungunya, dengue, and Zika are diseases transmitted by the tiger mosquito, which is now present almost everywhere in France and is active between May and November. During this period, mosquito control interventions are executed around places frequented by infected individuals to limit the risk of \u00a0local transmission\u00a0. These interventions aim to eliminate mosquitoes before they can infect others.<\/p>\n<\/div>\n<\/div>\n<h2 class=\"wall-content\">Many Sick, but Few Treatments<\/h2>\n<p>Another surprising fact about this start of the season: among this forty field investigations, only about a dozen resulted in \u00a0mosquito treatments\u00a0, which equates to less than one case out of four\u2026 How can we explain these low proportions?<\/p>\n<blockquote class=\"ac-article-quote wall-content\">\n<p>Many of our field investigations turned out negative. This means we did not find any tiger mosquitoes and therefore did not conduct treatment. This is explained by the particularly inclement weather conditions this month (rain and wind) in the department.<\/p>\n<footer><strong>Renaud Chevalier<\/strong><br \/>\n        Technical Manager at Altopictus in Haute-Garonne<br \/>\n    <\/footer>\n<\/blockquote>\n<h2 class=\"wall-content\">Four Treatments Wednesday Night in Toulouse<\/h2>\n<p>However, despite the tiger mosquitoes hiding from the weather, they have been biting more aggressively in recent weeks\u2026 and the epidemics continue to escalate. While chikungunya cases are declining in R\u00e9union with the onset of the austral winter, dengue cases are expected to rise soon in Martinique and Guadeloupe\u2026<\/p>\n<p>On the evening of Wednesday, June 4, the teams from Altopictus conducted \u00a0four treatments\u00a0 in the municipality of \u00a0Toulouse\u00a0, particularly in the neighborhoods of Lardenne, Purpan, and Borderouge.<\/p>\n<h2 class=\"wall-content\">Which Areas are the Most Affected?<\/h2>\n<p>In Haute-Garonne, most of the investigations conducted since early May \u2014 and the subsequent treatments \u2014 have focused on \u00a0the city of Toulouse and its immediate periphery\u00a0, \u201cwhere the bulk of the population resides,\u201d observes Renaud Chevalier.<\/p>\n<p>\u201cCampaigns have also taken place in northern Toulouse, especially at \u00a0Bouloc\u00a0, and even \u00a0Plaisance-du-Touch\u00a0. Conversely, since the beginning of the season in May, none have been conducted by Altopictus in Comminges.<\/p>\n<h2 class=\"wall-content\">69 Cases of Tropical Diseases over the Entire Year of 2024<\/h2>\n<p>For comparison, throughout \u00a02024\u00a0, only \u00a068 imported cases of dengue\u00a0 were documented in Haute-Garonne, alongside \u00a0one case of chikungunya\u00a0 and none of Zika. Last year, however, no \u00a0local cases\u00a0 were recorded in Haute-Garonne, unlike H\u00e9rault (three cases) and Pyr\u00e9n\u00e9es-Orientales (two cases).<\/p>\n<p>It\u2019s important to highlight that the majority of these figures are typically recorded during the \u00a0peak and end of the summer season\u00a0, between July and October, coinciding with\u2026 the return from summer vacations.
