Hantavirus 101: What Filipinos Need to Know About the MV Hondius Outbreak

If you’ve been active in social media these past weeks, we're sure you've heard of "Hantavirus" and its alarming outbreak on the cruise ship, MV Hondius.

The good news: Hantavirus is not the next COVID. But it is worth understanding, especially with 38 of our kababayan directly in the middle of this situation. 

Let's break it down. 

What Happened on the MV Hondius?

The MV Hondius is a Dutch-flagged cruise ship that left Ushuaia, Argentina on April 1, 2026, with around 150 passengers and crew, with most of the crew from the Philippines. By early April, passengers began falling ill, and three eventually died, two confirmed to have been infected with Hantavirus (Rappler, 2026, May 5). The ship docked in Tenerife, Spain, where passengers were evacuated and repatriated. 

As for our 38 Filipino crew members? All 38 tested negative for hantavirus. They are currently undergoing a 42-day quarantine in the Netherlands before safe repatriation (Rappler, 2026, May 10).  

So, What Exactly Is Hantavirus? 

Hantavirus is a rare viral infection that you get through direct contact with infected rodents, through their urine, feces, or saliva. Hindi siya nakakahawa, meaning you can’t catch it simply by being around someone who has it (Rappler, 2026, May 5).  

The specific strain involved in the MV Hondius outbreak is called the Andes virus. What makes this strain different from most other hantavirus types is that it has been documented to spread from person to person in rare cases involving very close and prolonged contact. According to DOH Secretary Teodoro Herbosa: "Hindi siya airborne gaya ng COVID or tuberculosis." It does not spread through casual contact or through the air in the same way COVID did (GMA News Online, 2026).  

Hantavirus infections can lead to two serious conditions depending on the strain: 

Hantavirus Pulmonary Syndrome (HPS): This affects the lungs. It starts with flu-like symptoms and can rapidly progress to severe respiratory distress.  

Hemorrhagic Fever with Renal Syndrome (HFRS): This affects the kidneys and is more common in Asia and Europe, caused by different hantavirus strains. 

There is currently no specific antiviral cure for hantavirus. Treatment focuses on managing symptoms and providing intensive supportive care, which is why early detection is critical.

Should Filipinos Be Worried? 

Hindi kayo dapat mag-panic but staying informed is always the right call. 

The DOH has confirmed that there have been zero recorded cases of hantavirus in Philippine history (GMA News Online, 2026). The disease is not endemic here, ibig-sabihin hindi ito naturally umiikot sa local rodent population. WHO Director-General Tedros Adhanom Ghebreyesus also stated clearly that the hantavirus outbreak on the MV Hondius is "not another COVID," and that the risk of a global pandemic from this virus is low (The Filipino Times, 2026, May 10).  

That said, being aware of how hantavirus spreads is useful information for everyone.

How Do People Get Hantavirus in General? 

The most common way hantavirus is transmitted globally through rodent contact. This can happen when you: 

• Breathe in air contaminated with dried rodent urine or droppings (especially in enclosed spaces like barns, cabins, or storage areas) 

• Touch your mouth or eyes after handling materials contaminated by infected rodents 

• Get bitten by an infected rodent 

Because of this, hantavirus risk is generally higher in rural or agricultural settings where rodent exposure is more common. In the Philippine context, ang mga taong nakatira o nagtatrabaho malapit sa mga bukid, bodega, o lugar na maraming daga ang may mas mataas na exposure. 

What Are the Symptoms to Watch For? 

Hantavirus infections typically progress in stages

Early stage (1 to 5 days after exposure): 

• Fever and chills 

• Muscle aches, especially in the back, thighs, and shoulders 

• Headache 

• Fatigue and tiredness 

• Nausea, vomiting, or diarrhea 

Later stage (4 to 10 days after early symptoms begin, for HPS): 

• Coughing 

• Shortness of breath 

• Lungs filling with fluid 

Most symptoms may appear as ordinary flu. Kung may history ka ng rodent exposure o nakapunta ka sa isang lugar na maraming daga at nagsimulang magkaramdam, it is important to tell your doctor right away. Early medical care can make a critical difference. 

How Is It Prevented?

Dahil walang bakuna at walang direktang lunas sa hantavirus, prevention is truly your best protection.

For general rodent exposure: 

• Seal gaps and holes in your home to prevent rodents from entering 

• Store food in tightly sealed containers 

• Keep your surroundings clean and clutter-free, especially in storage areas 

• Wear gloves when cleaning areas that may be contaminated with rodent droppings 

• Do not sweep or vacuum rodent droppings dry — dampen the area with disinfectant first before cleaning, to avoid aerosolizing the particles
