Inside an African lab that helped crack the hantavirus outbreak

Key Points:

• In early May, the Institut Pasteur de Dakar in Senegal rapidly identified the Andes strain of hantavirus on a stranded cruise ship off Cape Verde, aiding global health officials in managing a deadly outbreak with a high fatality rate.
• The Senegalese lab, part of the Pasteur Network, demonstrated critical capacity by sequencing the virus genome within 24 hours, confirming findings from labs in South Africa and Switzerland, and supporting WHO efforts in specimen collection and analysis.
• The outbreak involved about 150 passengers from 23 countries on the MV Hondius, with three deaths reported; the virus' long incubation period raises concerns about further cases and underscores the importance of tracing exposure windows, particularly in Latin America.
• Despite its vital role in outbreak response, the Institut Pasteur and similar global laboratory networks face funding cuts, including the termination of U.S. NIH support for emerging infectious disease research, raising concerns about preparedness for future pandemics.
• Health officials emphasize the need for maintaining and expanding global laboratory capabilities to detect and contain pathogens promptly, with sequencing essential to understanding transmission dynamics and guiding clinical and public health responses.
