HOUSTON – Health leaders stress the risk of hantavirus to the general public remains very low, even as officials continue monitoring an outbreak linked to a cruise ship.
On Monday, health officials in Nebraska said 18 American passengers were flown back to the United States and taken to a specialized quarantine facility in Omaha designed to handle highly infectious diseases.
Officials say one passenger tested positive for the virus and is now being treated inside a biocontainment unit. Another passenger with mild symptoms is receiving treatment in Atlanta.
As for the two passengers from the Houston area who were on the ship, the Texas Department of State Health Services says they are not showing any symptoms.
Officials say the two Texans were not sent to Nebraska because they left the ship last month before the virus was identified and had already returned home.
KPRC 2’s Re’Chelle Turner spoke to Dr. Peter Hotez, dean of the National School of Tropical Medicine at Baylor College of Medicine and co-director of the Texas Children’s Hospital Center for Vaccine Development about what Houstonians need to know.
“You know, the initial exposure probably happened off-ship, and probably the initial infection occurred when a couple was in southern Argentina,” Dr. Hotez said.
Dr. Hotez says it’s important to understand the incubation period — the time between when someone is exposed to the virus and when symptoms begin appearing.
Hantavirus incubation period
- Symptoms typically appear about three weeks after exposure
- The incubation period can last up to six weeks
- Officials say the outbreak timeline dates back to late March and early April
“So the likelihood is those two individuals who were in Texas who were exposed to the virus, I think there’s a good likelihood they will not turn out to have the hantavirus infection,” Dr. Hotez said. “So the point is, this is not COVID. It’s not nearly as transmissible as COVID.”
Turner also asked Dr. Hotez whether families should be changing anything they’re doing to protect themselves.
“There should be no fear in terms of getting hantavirus infection, at least from this epidemic,” Dr. Hotez said. “If you are concerned, one of the things to recognize is that rodents, mice, rats, do transmit other virus infections. And so if you have these animals in your garage or in your home and you’re sweeping up rodent feces or dry rodent urine and dust, you might want to wear a respirator mask and some glasses or goggles to protect yourself.”
Again, the two passengers from the Houston area are not experiencing any symptoms. State leaders are not releasing any additional details to protect their privacy.
