For Gilbert Zermeño, the news of a recent hantavirus outbreak is not just a headline—it is a visceral trigger. A photojournalist based in Arizona, Zermeño carries a burden that few can imagine: he is a survivor of a virus that claimed the lives of both his mother and sister more than two decades ago.
The trauma of 2002 remains an open wound. Zermeño recalls the devastating sequence of events in Texas, where he contracted the illness while cleaning his family’s home following the deaths of his relatives. Exposure to rodent droppings led to a severe infection that landed him in a Phoenix hospital for several days, fighting for his life.
“I imagine I got the same feeling that every person who’s ever contracted hantavirus and still deals with the effects afterwards of it,” Zermeño told CBS News’ “The Daily Report.” “It takes you back, and it’s no less painful now than it was back then. It’s hard. I’m not going to lie.”
As reports emerge of new cases—including a suspected outbreak linked to a Dutch-flagged cruise ship involving nine confirmed or suspected cases and three deaths—Zermeño finds himself in the unlikely position of being both a victim and a voice of reason. In an era of rapid digital misinformation, he is working to temper public panic with a perspective grounded in survival.
The Danger of Misdiagnosis and the Rarity of the Virus
One of the most harrowing aspects of Zermeño’s story is the initial medical confusion. His mother and sister were first told they were suffering from sepsis. It was only after their deaths that the cause was corrected to hantavirus. This rarity of the disease created a dangerous lag in care that nearly cost Zermeño his life as well.
Because hantavirus is uncommon, clinicians may not immediately consider it in a differential diagnosis, especially when symptoms mimic other respiratory or systemic infections. Zermeño notes that he only received a proper diagnosis and treatment after the intervention of family members within the medical community who recognized the specific pattern of the illness.
As a physician, I recognize this as a classic challenge in public health: the “zebra” problem. When doctors are taught to “look for horses, not zebras,” rare zoonotic diseases like hantavirus can be overlooked until the window for effective intervention has closed. Zermeño’s experience underscores the critical importance of providing detailed exposure histories—such as cleaning out old sheds or cabins—to healthcare providers.
Understanding Transmission: Why a Pandemic is Unlikely
The word “virus” often triggers a collective anxiety in the post-COVID-19 era. Zermeño has observed that online discourse has amplified this fear, leading some to believe that hantavirus could pose a widespread global threat. However, the biological reality of the virus is vastly different from that of SARS-CoV-2.
Hantavirus is primarily a zoonotic disease, meaning it jumps from animals to humans. In the Americas, it is typically transmitted through the inhalation of aerosolized particles from the urine, droppings, or saliva of infected rodents (such as the deer mouse). Unlike the flu or COVID-19, it does not easily spread from person to person.
Health officials have been quick to reassure the public. Ann Lindstrand, a World Health Organization representative in Cape Verde, stated that there is no risk of a pandemic-level threat due to the low likelihood of human-to-human transmission. Similarly, medical experts and officials associated with the CDC have emphasized that the risk to the general American public remains very low, noting that transmission requires extremely close contact and is not spread by asymptomatic individuals.
Hantavirus vs. Common Sepsis
To illustrate why Zermeño’s family was initially misdiagnosed, the following table compares the general presentation of hantavirus pulmonary syndrome (HPS) with general sepsis.
| Feature | Hantavirus (HPS) | General Sepsis |
|---|---|---|
| Primary Cause | Inhalation of rodent excreta | Overreaction to any systemic infection |
| Key Symptom | Rapidly progressing pulmonary edema | Widespread inflammation/organ failure |
| Transmission | Zoonotic (Animal to Human) | Non-communicable (Condition, not pathogen) |
| Diagnosis | Serology/PCR for hantavirus | Blood cultures/Lactate levels |
Practical Steps for Prevention
While the risk of catching hantavirus from another person is, in Zermeño’s words, “minuscule,” the risk from environmental exposure is real. For those cleaning out old buildings, garages, or campsites, the CDC recommends specific safety protocols to avoid aerosolizing the virus.
- Avoid sweeping or vacuuming: These actions stir up dust and virus particles. Instead, wet down the area with a bleach solution or disinfectant.
- Ventilate the space: Open doors and windows for at least 30 minutes before entering a confined area that may be infested with rodents.
- Wear protective gear: Use rubber or plastic gloves and, in heavily infested areas, a well-fitted N95 respirator.
- Seal entry points: Prevent rodent infestation by sealing holes in walls and storing food in rodent-proof containers.
Zermeño’s plea to the public is simple: do the research and listen to medical professionals. “It’s not as scary as COVID-19 was,” he insists, urging people to remain vigilant but calm.

Public health agencies continue to monitor the reports linked to the cruise ship outbreak to determine the exact strain of the virus and the nature of the exposure. The next official update from the World Health Organization regarding the cruise ship cases is expected as laboratory confirmations are finalized.
