In May 2024, German EMTs ASB, Cadus, Humedica and Johanniter conducted a joint disaster response field exercise including a Cholera outbreak scenario. The RRML CIBU (Cellule d’Intervention Biologique d’Urgence) from Institut Pasteur, France, embedded in an EMT, supported the exercise. Amateur actors presented injuries and cases of acute watery diarrhea with different levels of severity. Dummy samples were collected and transported to the RRML for analysis. An external IPC-Team from the German Robert Koch Institute conducted facility assessments to provide Cholera-specific IPC advice and training.

To assess

1. 1. the implementation of Cholera-specific IPC measures.

2. 2. the need for and benefit of external IPC support.

3. 3. the interoperability between EMTs and RRML.

Qualitative evaluation through observation and interviews.

All EMTs (n=4) had access to IPC guidelines and personal protective equipment (PPE) and implemented active screening for signs of infection (n=4). 75% (n=3) of the EMTs actively isolated suspected cholera cases. EMTs underlined the benefit of external IPC support (n=3) and training provided (n=4). 48 EMT staff were trained in donning/doffing of PPE and management of spill events. The RRML provided transport material and training on packaging of samples. Occasional contamination of the outer packaging and incorrectly filled-in lab forms were reported. Sample transport was aligned to lab schedule.

The EMTs adapted competently to the Cholera scenario. Interoperability with the RRML was satisfying. The IPC team was seen as important support. Lessons learned included the need for improved isolation precautions, packaging of samples and completion of lab forms.
