Hantavirus Tracker

A French woman repatriated from the hantavirus-hit MV Hondius has tested positive for Andes hantavirus, becoming the first confirmed case outside the ship since the outbreak began.

The case introduces a new vector of potential spread — air travel — as the woman developed symptoms during the repatriation flight, forcing French authorities to trace and isolate 22 close contacts, many of whom were on the plane.

1. French traveler tests positive for Andes hantavirus after cruise

A French woman who sailed on the hantavirus-hit cruise ship MV Hondius has tested positive for Andes hantavirus after being repatriated to France.

French Health Minister Stephanie Rist confirmed the case on May 11, 2026, and said the woman’s condition worsened overnight, requiring transfer to a specialized infectious disease hospital.

She was one of five French nationals evacuated from the ship and developed symptoms during the repatriation flight. French authorities have identified 22 close contacts and ordered them to isolate.

The patients were placed under strict isolation upon arrival, as hantaviruses are zoonotic viruses transmitted from rodents to humans, according to the World Health Organization.

Key facts:

- French woman tested positive for Andes hantavirus after returning from MV Hondius cruise.

- Health Minister Stephanie Rist confirmed the case on May 11, 2026.

- Patient was among five French nationals evacuated and repatriated yesterday.

- Symptoms developed during repatriation flight; condition worsened overnight.

- 22 close contacts identified and ordered to isolate in France.

Why it matters: This case extends the hantavirus cluster beyond the immediate cruise ship environment and into a European country, raising the stakes for cross-border outbreak response.

France’s rapid identification of close contacts and isolation orders signal a heightened alert for person-to-person transmission risk, which is rare for hantaviruses but possible with the Andes strain.

Public health authorities in other countries with passengers from the MV Hondius should watch for similar imported cases.
