Key Points

Surveillance Systems

• The proportion of mandatory electronic reports (or e-reports) for all associated notifications (notifications of active tuberculosis, notifications of latent tuberculosis infections, and notifications of treatment outcomes) was 63% in 2023 in Occitanie, higher than the e-reporting rate in France, which was 50%. The year 2024 showed an increase, with 70% of cases reported electronically.

• Since the completeness of the DO relative to the actual number of cases has not been reassessed for several years, a new national completeness study is scheduled for 2025.

• Public health officials need the support of clinicians, microbiologists, and other frontline workers to strengthen electronic reporting and surveillance, which guide public health control measures.

Active Tuberculosis

• With 368 reported cases of active tuberculosis (AT) in 2023 compared to 272 cases in 2022, the number of AT cases diagnosed among residents of Occitanie increased by 35% compared to 2022.

• This increase was also observed at the national level (+16.7%) and across Europe.

• In 2023, 43% of these TB cases were reported via electronic reporting.

Treatment Outcomes

• With 207 treatment outcomes (IDT) (corresponding to tuberculosis cases reported in 2022), this information was available for 76% of cases, an increase compared to the 2018–2021 period. The national average was 48%. In 2023, 63% of these TDRs were reported via electronic reporting, with an increase in 2024 (87%).

Latent Tuberculosis Infections in Children and Young Adults

• The number of latent tuberculosis infections (LTIs) reported in 2023, at 320 cases, rose sharply (+37%) compared to 2022. More than 57% of these LTIs involved children over the age of 15, many of whom were runaway or unaccompanied minors.
