Philips News reports that Global health authorities are intensifying efforts to contain the rare
hantavirus outbreak linked to the Dutch expedition cruise ship
MV Hondius, as new infections, quarantines, and passenger tracking operations continue across multiple countries.
The outbreak has now become one of the most closely monitored infectious disease incidents of 2026 due to the involvement of the Andes strain of hantavirus — a rare subtype capable of limited human-to-human transmission.
Hantavirus Update Today May 24, 2026:

9. CDC Issues New Hantavirus Testing Alert for Doctors
The CDC has issued updated guidance for clinicians on testing suspected hantavirus cases as global monitoring efforts continue.
10. What We Know About the 2026 Hantavirus Cruise Ship Outbreak
Authorities say the Andes hantavirus outbreak aboard the MV Hondius remains the largest hantavirus event of 2026, with investigations ongoing.
What Is Hantavirus?
Hantavirus is a rare but potentially deadly virus commonly spread through exposure to infected rodents, their urine, saliva, or droppings.
Symptoms may include:
- Fever
- Muscle pain
- Headache
- Fatigue
- Vomiting
- Shortness of breath
- Severe pneumonia-like illness
In serious cases, the disease can rapidly progress into Hantavirus Pulmonary Syndrome (HPS), which can be fatal.
Why Experts Are Concerned
Most hantavirus strains do not spread between humans. However, the Andes strain linked to the current outbreak is one of the few known variants capable of person-to-person transmission through prolonged close contact.
Despite the growing international response, the WHO says the overall public health risk remains low and there is currently no evidence of widespread transmission.

The outbreak is unusual because hantavirus infections are rarely linked to cruise ships. Health officials are investigating possible exposure during excursions and limited onboard transmission.
How dangerous is hantavirus?
Hantavirus can be life-threatening, especially when it develops into Hantavirus Pulmonary Syndrome (HPS), which affects the lungs and breathing.
How can people protect themselves from hantavirus?
People can reduce risk by avoiding contact with rodents, safely cleaning contaminated areas, wearing protective gear during cleanup, and seeking medical care if symptoms appear.
Is the WHO monitoring the hantavirus outbreak?
Yes, the World Health Organization (WHO) is monitoring the outbreak and coordinating with international health agencies.
Are there confirmed hantavirus cases in the United States?
U.S. health authorities are monitoring travelers connected to the outbreak, but officials continue investigations into possible cases and exposures.
