Mexico: zero cases, but control tightened

Mexico has not recorded a single hantavirus case. But the measures are serious. Authorities have strengthened epidemiological surveillance nationwide.

Hospitals, ports, airports, and medical units are under monitoring. Any patient with ARVI symptoms and a link to the cruise ship is under suspicion.

Mexico's Ministry of Health confirmed: 'Not a single suspected, probable, or confirmed case.' But vigilance remains high.

South Africa: 42 of 62 contacts found

South African authorities are searching for people who came into contact with infected passengers. 42 out of 62 have been found. Among them — healthcare workers.

Two infected passengers arrived in South Africa. One via Saint Helena, another on an evacuation flight.

The remaining 20 contacts are being traced. Time matters: the hantavirus incubation period reaches six weeks.

Argentina and CDC: hunting for reservoirs

Directors of ANLIS Malbrán (Argentina) and the US CDC met to coordinate. A joint operation is planned in Mendoza province.

The goal — detect hantavirus circulation in natural reservoirs. Specifically, rodents — the virus carriers.

Special attention is given to areas where the first infected passenger traveled before boarding the MV Hondius.

Why this matters

Andes hantavirus is the only hantavirus that spreads from person to person. That is why international coordination is critical.

The outbreak affected 23 countries. Passengers scattered across the globe. Contact tracing is the only way to prevent further spread.

What other countries are doing

  • UK: 20 people quarantined at Arrowe Park Hospital
  • Canada: 10 people under monitoring, one confirmed case
  • France: patient in critical condition in ICU
  • Spain: confirmed case in a cruise passenger
  • Netherlands: crew isolation in Rotterdam port

Global picture

To date — 13 confirmed cases, 3 deaths. WHO assesses the global risk as low. But the situation continues to evolve.

The most important thing is coordination. The virus knows no borders. The only way to stop it is through joint work by all countries.
