Hondius Andes Hantavirus Update: Case Numbers Stabilize, Tracing Intensifies
Public health authorities continue monitoring the MV Hondius Andes hantavirus outbreak off Praia, Cape Verde. Latest reports indicate stabilization of confirmed cases, with intensive contact tracing efforts underway on and off the vessel.
Latest Situation Report: Stabilizing Case Trends
Praia, Cape Verde – 2026-09-20 – The multi-agency response to the hantavirus outbreak aboard the MV Hondius Andes, currently anchored off Praia, continues to focus on containing transmission and monitoring affected individuals. As of today, publicly reported figures indicate a stabilization in the number of confirmed hantavirus cases associated with the cruise ship. This marks a notable shift from previous reporting periods which saw a more rapid increase in identified infections. Officials from the World Health Organization (WHO) and Africa Centres for Disease Control and Prevention (Africa CDC) have emphasized the critical importance of this plateau in new detections. While not indicative of an end to the outbreak, it suggests that isolation protocols and infection control measures implemented both on the vessel and in onshore facilities may be having an effect.
Intensive Contact Tracing Underway
Contact tracing efforts have been bigly intensified over the past 24 hours.Teams comprising personnel from the US Centers for Disease Control and Prevention (US CDC), European Centre for Disease Prevention and Control (ECDC).

Next Steps in the Response
Health authorities reiterate that the situation remains fluid. Ongoing surveillance, strict adherence to infection prevention and control (IPC) measures, and continued public health messaging are paramount. The focus for the immediate future includes:
- Sustained Surveillance: Continuous monitoring for new cases among the remaining population on the ship and identified contacts. * Enhanced Diagnostics: Processing of samples to confirm or rule out infection, with efforts to reduce turnaround times. * Public Health Communication: Providing transparent and regular updates to affected individuals and the broader public, while respecting patient confidentiality. * Logistical Support: Ensuring an uninterrupted supply chain for medical equipment, personal protective equipment (PPE), and essential provisions.
