Why Experts Say It’s Unlikely to Become “The Next COVID”
One of the biggest reasons health experts are downplaying pandemic fears is the way hantavirus spreads.
COVID-19 became a global catastrophe because infected people could spread the virus easily — often before showing symptoms. Hantavirus does not behave that way.
Experts say several factors make widespread global transmission unlikely:
1. Human-to-Human Transmission Is Rare
Most hantavirus infections come from rodent exposure, not infected people. Even the Andes strain, which can spread between humans, requires extremely close and prolonged contact.
That makes it fundamentally different from COVID-19, which spread rapidly through everyday social interaction.
2. Transmission Is Slow
Researchers explain that Andes virus has a much longer incubation period compared to COVID-19. That gives public health officials more time to trace contacts and isolate potential cases before large outbreaks occur.
3. Severe Symptoms Appear Quickly
Many patients with severe hantavirus become critically ill soon after symptoms begin. Experts note that this reduces the likelihood of infected individuals moving freely through communities while unknowingly spreading the disease.
4. Historical Evidence Does Not Support Pandemic Spread
Hantavirus is not new. Scientists have studied it for decades, and while localized outbreaks have occurred, it has never demonstrated the kind of transmission pattern associated with global pandemics.
The Cruise Ship Outbreak That Triggered Global Attention
The recent outbreak aboard the MV Hondius became international news after multiple passengers developed severe respiratory illness during the voyage.
According to WHO reports:
- Several passengers tested positive for hantavirus
- Multiple deaths were reported
- Passengers from numerous countries were potentially exposed
- Health agencies began monitoring travelers after disembarkation
The outbreak raised fears because cruise ships are often associated with rapid disease spread, especially after memories of COVID-19 outbreaks on ships early in the pandemic.
However, WHO and other health authorities emphasized that the current situation is being handled with strict containment measures, including isolation protocols, medical monitoring, and coordinated international response efforts.
