What happened today

The MV Hondius arrived at Granadilla port, Tenerife, at 04:30 UTC, formally ending its 70-day voyage from Ushuaia. Spanish authorities began passenger transfer to Madrid military quarantine immediately, while the U.K. Health Security Agency confirmed two British nationals from the ship had tested positive for Andes virus and identified one additional suspected case under investigation.

The CDC formally walked back the previously planned quarantine for 17 returning American passengers, citing absence of symptoms and elapsed incubation window. Two Singaporean residents previously listed as suspected tested negative and were released from isolation, the first net reduction in suspected cases since the cluster was identified. Total figures hold at 6 confirmed, 3 suspected, 3 deaths across 14 traced countries.

Today's most-asked questions

Is the MV Hondius hantavirus situation getting worse?

No. The trajectory is stable to slowly resolving. Confirmed case count rose by 1 today (UK), but suspected cases dropped by 2 (Singapore tested negative). Net active cluster size held at 9 cases / 3 deaths. The ship has now docked, ending the maritime exposure phase. Remaining open questions resolve to confirmed-or-ruled-out within the next 7-14 days as PCR tests complete.

What does "Day 70" mean?

Day 70 measures elapsed days since the index case (a 70-year-old Dutch national) developed symptoms aboard MV Hondius on 6 April 2026. We use this metric for cluster duration tracking — analogous to how influenza or COVID outbreaks track epidemiological week. Andes virus has an incubation period of 1-6 weeks, so any new case beyond Day 42-49 from initial exposure is increasingly unlikely to be attributable to the cluster.

Should I be worried if I was on a flight from Saint Helena or Johannesburg?

If you were on the specific KLM flight from Saint Helena via Johannesburg on 25 April 2026, contact your country's public health authority — they likely already have your details through aviation contact tracing. If you were on any other flight, no. Casual airline contact with someone who later proved positive is not a meaningful Andes virus exposure given the transmission biology. More on hantavirus aerosol transmission.

Are American passengers being quarantined?

No. The CDC has formally walked back the previously planned quarantine for 17 returning U.S. passengers, citing absence of symptoms and incubation window beyond Andes virus's 6-week maximum. Returning passengers are being monitored at home with self-reporting protocols rather than institutional quarantine.

Is hantavirus spreading in the United States?

Not in the cluster sense. The U.S. continues to report sporadic Sin Nombre virus cases at the historical baseline (20-40 per year, almost all in the Southwest from deer mouse exposure). No Hondius-linked cases have presented symptomatically among the 17 returning passengers being monitored. The CDC HAN528 advisory states the risk of broad U.S. spread is "extremely unlikely."

Where can I track this in real time?

The main dashboard updates every 4 hours during active outbreaks. Telegram alerts are sent for any confirmed cluster status change (free tier). For real-time API access including suspected cases and webhook delivery, see Pro tier.
