The Moroccan Ministry of Health and Social Protection has confirmed cases of diphtheria in the Souss-Massa region, marking a concerning resurgence of the disease in the country. According to the ministry, two family clusters were identified, one in the Akadير Idrissane district and the other in the Ashouk Ait Baha province. One case was confirmed through laboratory testing, while eight others are under investigation, including two reported deaths. Preliminary data suggest that the affected children either did not receive the vaccine or did not complete the recommended doses.
Dr. Taieb Hamdi, a physician and researcher in health policies and systems, emphasized that the confirmation of diphtheria cases in Souss-Massa is a significant health alert. He noted that Morocco had not recorded cases of the disease for over three decades, making its resurgence a major development after a prolonged period of control. Dr. Hamdi highlighted that the presence of two family clusters indicates the transmission of the infection within the close environment of the detected cases.
Diphtheria is a bacterial infection caused primarily by Corynebacterium diphtheriae, with the risk of severe complications, including respiratory obstruction and cardiac problems. The disease is transmitted mainly through respiratory droplets and close contact. Dr. Hamdi stressed that the rapid initiation of treatment is crucial when there is a strong suspicion of infection, including the administration of antibiotics and antidiphtheria serum when necessary.
The resurgence of diphtheria in Morocco is linked to the level of immunity within the community, particularly among children. Dr. Hamdi explained that the disease was once a major childhood illness, but vaccination efforts have significantly controlled its spread. However, declining vaccination coverage and incomplete vaccination schedules can lead to the formation of pockets of unprotected individuals.
Dr. Hamdi warned that the emergence of diphtheria in the Akadir region warrants special attention due to weak vaccination coverage, which could be repeated in other areas if no decisive action is taken. He drew parallels with the experience of the measles outbreak, which began in Souss-Massa in 2023 and spread to other regions, highlighting the importance of maintaining high vaccination coverage.
The researcher emphasized that the current priority is to rapidly identify all contacts of the cases, subject them to testing and monitoring, and ensure they receive preventive treatment. He also called for targeted vaccination campaigns to address areas with inadequate vaccination coverage and prevent further transmission of the disease.
Dr. Hamdi concluded that while there is no need for widespread panic, the resurgence of diphtheria should not be dismissed as an isolated incident. He stressed that this new alert, following the measles outbreak, underscores that vaccination gains are not definitive and that declining vaccination rates can lead to the return of diseases once thought to be rare.
