"French Passenger's Andes Virus Matched South American Strains"

PARIS (AP) — France’s Pasteur Institute said it has fully sequenced the Andes virus detected in a French passenger from the MV Hondius cruise ship and found that it matched viruses already known in South America, with no evidence so far of new characteristics that would make it more transmissible or more dangerous

PARIS (AP) — France's Pasteur Institute has completed the full sequencing of the Andes virus found in a French passenger from the MV Hondius cruise ship. The institute confirmed that the virus closely matches those already identified in South America, with no indications thus far of any new traits that could make it more transmissible or dangerous. Health Minister Stéphanie Rist announced this on X, emphasizing that the analyzed virus corresponds with known strains being monitored in the region.

According to Rist, “At this stage, no element suggests the emergence of a more transmissible or more dangerous form of the virus.” The genomic analysis conducted by the Pasteur Institute confirmed that the virus from the French passenger matched other strains detected aboard the cruise ship and bore a close resemblance to existing Andes virus samples active in South America.

The findings are significant as they highlight that the viruses found among patients on the MV Hondius are identical to one another, showing approximately 97% similarity to Andes viruses present in South American rodents. Jean-Claude Manuguerra, head of the Pasteur Institute's Environment and Infectious Risk unit, noted that the remaining genetic variation seems to reflect natural viral diversity and does not appear to alter the characteristics of the virus that has affected travelers.

The French passenger, who tested positive for the virus after traveling on the MV Hondius, is currently receiving treatment in Paris. Initially reported to be in serious condition, the case is part of a broader outbreak on the cruise ship, which has seen a total of 11 reported cases, out of which nine have been confirmed. Tragically, three individuals on the cruise have died, including a Dutch couple believed to have been the first to contract the virus during their travels in South America.

The outbreak on the MV Hondius has raised concerns regarding hantavirus transmission, prompting health officials to ensure rigorous monitoring and response strategies. The sequencing of the virus provides essential data that aids in understanding its behavior and potential rapid transmission among populations. Rist stated that this information would be shared globally with the scientific community to enhance collaborative efforts in monitoring and responding to the situation.

As the situation unfolds, health authorities remain vigilant in tracking the spread of the virus and ensuring that adequate measures are in place to safeguard public health both locally and internationally. The Pasteur Institute's detailed genomic sequencing enhances the scientific understanding of hantaviruses and assists in developing strategies to combat any potential health threats they might pose.
