A new fear is spreading. First, it was a rare disease from rodents. Now, the World Health Organization says human-to-human transmission cannot be ruled out on the cruise ship where three people have already died.
The headlines are alarming. Social media is panicking. People are asking the same question: is this the next COVID-19?
Here is what the WHO actually said, whether human-to-human transmission is confirmed, and whether you should be worried.
THE SHORT ANSWER
No, this is not the next COVID-19. The WHO explicitly stated that hantavirus “is not a virus that spreads like flu or like COVID. It’s quite different.”
Some human-to-human transmission may have occurred on the MV Hondius cruise ship. The WHO is assuming this as a precaution. But this would be extremely rare and likely required very close, prolonged contact. The risk to the general public remains low.
Hantavirus is not airborne like COVID-19. It spreads primarily through rodent droppings, urine, or saliva. Human-to-human transmission, if confirmed, would be a rare exception, not the norm. This outbreak is tragic. It is not a pandemic.
WHAT THE WHO ACTUALLY SAID
Dr. Maria Van Kerkhove, WHO’s Director for Epidemic and Pandemic Preparedness and Prevention, addressed reporters on Tuesday.
Key quotes:
“We do know that some of the cases had very close contact with each other and certainly human-to-human transmission can’t be ruled out so as a precaution this is what we are assuming.”
“The risk to the general public is low. This is not a virus that spreads like flu or like COVID. It’s quite different.”
The WHO is taking a precautionary approach. That is their job. They are not declaring a new pandemic. They are not saying hantavirus has mutated into an airborne super-spreader.
WHAT IS HANTAVIRUS?
Hantavirus is a family of viruses carried by specific rodent species.
Normal transmission: Humans inhale aerosolized virus from rodent urine, droppings, or saliva. This usually happens when cleaning old sheds, cabins, or other enclosed spaces where rodents have been active.
Symptoms: Fever, muscle aches, fatigue, then shortness of breath and fluid buildup in the lungs. Hantavirus Pulmonary Syndrome (HPS) has a fatality rate of 30-50%.
Known human-to-human transmission: Only one strain (Andes virus in South America) has ever shown human-to-human transmission. It is rare. It requires very close contact with an infected person’s bodily fluids.
The current outbreak on the MV Hondius involves a European strain. Human-to-human transmission would be unusual. The WHO is not confirming it. They are saying it cannot be ruled out.
THE CURRENT OUTBREAK
The ship: MV Hondius, a Dutch-flagged cruise ship. It departed Ushuaia, Argentina last month on a voyage across the Atlantic.
The situation: Almost 150 people (including 17 Americans) remain stranded off the coast of Praia, Cape Verde.
Cases: 7 cases of hantavirus identified so far. Two confirmed. Five suspected.
Deaths: Three people have died – a Dutch couple and a German national.
Illnesses: One British national remains in intensive care in South Africa. His condition is improving. Two other people with symptoms remain on board.
The concern: Cases had very close contact with each other. That raises the possibility of human-to-human spread.
COULD THIS BE THE NEXT COVID-19?
No. Absolutely not. Here is why.
1. Hantavirus is not airborne. COVID-19 spreads through respiratory droplets and aerosols. Hantavirus does not. It requires direct contact with rodent droppings or, in rare cases, very close contact with an infected person’s bodily fluids.
2. The reproduction number (R0) is low. COVID-19 had an R0 of 2-3 (each infected person infected 2-3 others). Hantavirus has an R0 close to zero for human-to-human transmission.
3. The incubation period is different. Hantavirus takes 1-8 weeks to show symptoms. That makes rapid spread unlikely.
4. The fatality rate is high but transmission is low. A disease that kills 30-50% of infected people but barely spreads is a tragedy. It is not a pandemic.
5. The WHO is not alarmed. They explicitly said the risk to the general public is low. They are taking precautions. They are not issuing global warnings.
6. We have experience. Since COVID-19, global health systems have improved surveillance, testing, and response. Even if human-to-human transmission is confirmed, containment would be possible.
WHAT WOULD CONFIRM HUMAN-TO-HUMAN TRANSMISSION?
Scientists would need to:
- Rule out a common rodent source on the ship
- Show that cases had no rodent exposure
- Trace the infection from person to person directly
- Genetically sequence the virus to show it is identical between cases
This has not been done yet. The WHO is assuming transmission as a precaution, not as a confirmed fact.
SHOULD YOU BE WORRIED?
No. Not unless you are on that cruise ship or cleaning a rodent-infested building without protection.
For the general public: The risk is effectively zero. Hantavirus does not spread easily. You cannot catch it from a cough or a sneeze.
For cruise ship passengers on other ships: Risk is extremely low. The outbreak is contained to one vessel. This is a rare, unusual event.
For people in rodent-prone areas: Normal precautions apply. Avoid rodent droppings. Wear a mask and gloves when cleaning infested areas. Ventilate closed spaces before entering.
For public health officials: This is a concern. They will monitor for further cases. They will investigate the transmission route. They will update guidance if needed.
THE BOTTOM LINE
The WHO has not confirmed human-to-human transmission of hantavirus. They said it “cannot be ruled out” and are assuming it as a precaution.
Is that true? The WHO’s statement is accurate. They are being cautious.
Can it be the next COVID-19? No. The WHO explicitly said hantavirus does not spread like flu or COVID. The risk to the general public is low.
What you should do: Nothing different. This is not a threat to you. Follow the news if you are curious. Do not panic. Do not stockpile supplies.
What you should not do: Spread misinformation. The headlines are alarming. The reality is reassuring.
Three people have died. That is tragic. But a tragedy is not a pandemic. The world is not shutting down. The next COVID-19 is not here. And with the precautions we have learned, it may never be.
