Stop worrying about Ebola: Protect yourself from contagious viruses you may actually encounter

Stop worrying about Ebola – In the wake of recent viral outbreaks, fears surrounding diseases like Ebola have intensified. However, experts argue that these concerns might be exaggerating the risk for everyday travelers. Dr. Thomas Moore, a clinical professor of medicine at the University of Kansas School of Medicine-Wichita, reassures that the threat posed by such viruses to the average person is minimal. “The headlines are scary, but honestly, the risk to the average traveler from these viruses is essentially nonexistent,” he says.

The Invisible Enemy: A Growing Anxiety

Despite the low risk for most people, the allure of viral threats persists. Dr. Ronald Nahass, president of the Infectious Diseases Society of America and clinical professor of medicine at Rutgers Robert Wood Johnson Medical School, notes that people are always fixated on the latest viral scare. “A virus is intangible: You can’t see it, can’t feel it until you are sick, so it’s a real concern for many people. I call it the invisible enemy,” he explains.

Compounding this fear is the lingering psychological impact of the pandemic. “Our collective PTSD about Covid has made us more susceptible to anxiety over the next potential outbreak,” Nahass adds. This mindset, he says, can lead to a misplaced focus on viruses like Ebola, which, while deadly, have distinct transmission patterns compared to other diseases.

Viral “Personality” and Transmission Dynamics

Dr. William Schaffner, a professor of infectious diseases, health policy and prevention at Vanderbilt University Medical Center, highlights that each virus has its own unique characteristics. “Think of all your cousins. They may all have the same last name, but each one is distinctive and individual,” Schaffner uses as a metaphor. While Ebola has captured global attention, it differs significantly from viruses that are more commonly encountered in daily life.

According to Schaffner, Ebola spreads through direct contact with bodily fluids such as blood, saliva, or feces. In regions like Africa, the disease often transmits via traditional burial practices where mourners touch the infected body as part of a ritual. “In addition, family members care for sick loved ones in their homes as they get progressively ill, and that’s where the transmission occurs to the caregivers,” he explains. However, the virus does not easily spread in crowded settings like airplanes, where most people remain asymptomatic.

“A person on an airplane infected with Ebola who is perfectly healthy and has no symptoms is of no risk to anybody else on that airplane,” Schaffner says. He emphasizes that the contagiousness of a virus depends on its stage of development. “Remember, it’s only when the infected person becomes seriously sick that they become hazardous to others. This is a very difficult concept for people to grasp,” he adds, noting that many overestimate the danger of catching a virus in transit.

Lesser-Known Viruses: A Hidden Risk?

While Ebola dominates headlines, other viruses like hantavirus also warrant attention. Most strains of hantavirus in North America are not contagious between humans, but the Andes strain stands out. This rare variant, found in Argentina and Chile, is capable of limited person-to-person spread. “The Andes strain was responsible for the recent hantavirus outbreak that killed three people aboard the Dutch luxury cruise ship MV Hondius,” says Schaffner.

Authorities suggest that some individuals on the cruise were already exposed to the virus before boarding. “To spread, the Andes hantavirus needs direct physical contact, prolonged time spent in close or enclosed spaces, and exposure to the sick person’s body fluids,” the CDC states on its website. Schaffner describes the situation on the cruise as an example of “cheek-by-jowl” interactions, where constant contact with fellow passengers and crew still resulted in only a small number of infections. “Although Andes is a contagious virus, it may not be very contagious,” he concludes.

The World Cup: A Perfect Storm for Contagion

As the World Cup approaches in June, bringing millions of fans to stadiums across the US, Mexico, and Canada, health officials are bracing for a potential surge in infectious disease cases. The event, with its packed crowds and shared spaces, creates an ideal environment for a “mass contamination event.” Yet, the viruses most at risk of spreading are not the exotic ones like Ebola, but rather those that are more familiar in everyday settings.

Measles, one of the most contagious viruses in existence, is a primary concern. “An unvaccinated person at the World Cup could carry measles back to a community with low vaccination rates,” says Nahass. He points out that recent drops in immunization coverage in the US, Canada, Mexico, the United Kingdom, and parts of Europe have left pockets of the population vulnerable. “Most concerning right now to those of us in infectious disease is measles, with pockets of the US undervaccinated,” he adds. The ease of containment through vaccination makes this virus a focal point for public health.

While the World Cup may amplify the risk of measles transmission, it also serves as a reminder of the broader challenges in viral disease prevention. “The same viruses that experts say you should worry about at home, work and school are the ones we need to monitor closely,” Schaffner says. This underscores the importance of understanding the specific behaviors and environments that facilitate viral spread, rather than defaulting to fear of the unfamiliar.

Grasping the Reality of Viral Risks

For many, the fear of viral outbreaks is rooted in a lack of familiarity with their transmission mechanisms. “It’s easy to overlook how certain viruses operate,” Schaffner says. “They don’t spread on their own without a specific pathway, and that’s what people often forget.” Whether it’s the direct contact required for Ebola or the airborne droplets of measles, each virus demands a tailored approach to prevention.

Health officials stress that while the World Cup may create opportunities for viral spread, it’s not a guaranteed event. “The key is to recognize that not every virus behaves the same way,” says Nahass. “Ebola may be a headline grabber, but measles is a more immediate threat for those who haven’t been vaccinated.” This distinction highlights the need for public education on viral dynamics and the importance of maintaining high immunization rates to curb outbreaks.

Ultimately, the goal is to balance awareness with perspective. “Fear of one virus shouldn’t automatically translate to fear of another,” Schaffner says. “Each has its own set of rules, and understanding those rules helps us protect ourselves more effectively.” As the World Cup draws near, this mindset will be crucial in ensuring that the event remains a celebration of sport rather than a catalyst for widespread illness.
