The epidemic of dengue fever in Réunion but increases in Saint-Gilles-le-Ben and Saint-Marie

From May 27 to June 2, 393 cases were confirmed. Although the number of reported cases is decreasing and weather conditions are less conducive to mosquito development, the circulation of the dengue virus continues in all the island's municipalities.

Compared to 2018 at the same time of the year, reported cases for this year are more scattered on the island and their number is higher. Therefore, the mobilization of all should continue at the beginning of the southern winter to continue to master this dynamics.

Epidemiological situation as of 12 June 2019 (data from OI Wax, Public Health France):

The drop in the number of cases is already underway, reporting less than 400 cases per week (compared to more than 1300 per week at the peak of the epidemic) or more than 15,000 cases confirmed since the beginning of the year. But viral circulating continues to affect almost the entire island and the spread continues: the share of reported cases to the west and north continues to grow at the expense of southern homes.

The activity of historic homes in the South continues to decline (except Saint-Joseph). As in recent weeks, despite the significant decline, Saint-Pierre is still the most important home.

To the west there is an increase in the number of cases in Saint-Gilles-les-Bains. Everywhere, activity is stable in other Western municipalities, which now account for more than a quarter of the total number of cases.

To the north, the number of cases increased in the municipality of Sainte-Marie but stabilized in Saint-Denis and Sainte-Suzanne. In Saint-Denis, however, the scattering of the affairs in the city, including Brittany, is still visible. The Seventh now accounts for 7% of the total number of cases.

To the east, the majority of the cases are in Saint-André. The number of cases in other eastern municipalities remains stable and low.

From the beginning of the epidemic:

• More than 22,000 confirmed Aboriginal cases (over 15,000 cases since 01/01/2019)
• 670 hospitalizations
(including 514 hospitalizations from 01/01/2019)
• 2175 visits to the emergency room
(including 1,700 visits to emergency departments since 01/01/2019)
• Over 68,000 clinically challenging cases (including nearly 42,000 cases from 01/01/2019)
• 15 deaths, 8 of which are directly related to dengue fever. (From 01/01/2019: 9 deaths, 5 of which are directly related to dengue fever).

Despite entering the Australian winter, we must continue to act to limit the dispersal of cases and to continue the fight against the epidemic
