Key Points

COVID-19

In Occitanie, according to data available as of March 16, 2022, for week 10 of 2022, incidence and positivity rates were slightly higher than the previous week: a positivity rate of 23.3% (versus 22.9% in week 09-2022, an increase of 0.4 percentage points) and an incidence rate of 583 cases per 100,000 inhabitants (versus 560 in week 09-2022, an increase of 4%) (Table 5, Figure 8). The testing rate was generally stable at 2,504 per 100,000 inhabitants versus 2,450 in week 09-2022, an increase of 2%. At the regional level, the three virological indicators were increasing compared to week 09 among those under 20 years of age (particularly among those under 10) and among those aged 65 and older.

The effective reproduction number (R_e) estimated from regional SI-DEP data through March 12, 2022, was 0.94 (0.93–0.95), an increase compared to the previous week (0.73).

At the departmental level, an incidence rate exceeding 400 cases per 100,000 inhabitants was estimated for Week 10 of 2022 in all departments of the region, with Gers having the highest rate (780 cases per 100,000 inhabitants) (Table 5). Incidence rates, like testing rates, were higher than in week 09 in 6 departments (Tarn-et-Garonne, Tarn, Gard, Pyrénées-Orientales, Lot, and Aveyron), with increases in incidence rates more pronounced than those in testing rates (Table 7); indicators were stable or decreasing in the other departments.

Influenza and Influenza-Like Illness

The region has been in an epidemic phase for 13 weeks. After an increase in late December, indicators declined in early January and then stabilized at a high level. Nationally, indicators are rising sharply, and all metropolitan regions have entered an epidemic phase except for Corsica.

Acute gastroenteritis

• In hospital settings, according to data reported by emergency departments to the Oscour® network, gastroenteritis activity was high in week 10 of 2022 (Figure 15). Visits of all ages for a diagnosis of gastroenteritis were, as in the previous week, decreasing compared to the week before. In week 10 of 2022, 550 visits for gastroenteritis were recorded (including 375 for patients under 5 years of age), representing 2.0% of all visits (versus 595 visits in week 09 of 2022).

• In private practice, according to data from the SOS Médecins associations in Nîmes, Montpellier, and Perpignan (SOS Toulouse excluded from the analysis due to missing data since February 16), gastroenteritis activity was low in week 10-2022 (Figure 17). Procedures for gastroenteritis diagnoses across all age groups were down compared to the previous week (Figure 18), with 115 procedures for this diagnosis, including 37 for patients under 5 years of age—representing 5.4% of the total activity of the three available SOS Médecins associations (versus 158 procedures in week 09-2022).

• According to data from the Sentinelles network, the incidence rate of acute diarrhea cases seen in general practice was 77 per 100,000 [40; 114], an increase compared to the previous week (53 per 100,000) but stable over the preceding weeks.
