Protect yourself from contagious viruses with these expert tips

Headlines regarding rare, high-profile viruses often trigger anxiety, yet infectious disease experts emphasize that the risk to the average traveler remains essentially nonexistent. While these pathogens are often perceived as an “invisible enemy,” medical professionals warn that collective stress following the COVID-19 pandemic may be fueling unnecessary alarmist reactions to international health reports.

Dr. Thomas Moore of the University of Kansas School of Medicine-Wichita notes that fear should not be applied universally across different viral threats. Each virus possesses a unique “personality,” and concerns regarding one outbreak do not necessarily translate to risks from another.

Understanding Real Risks vs. Media Headlines

Ebola, for instance, requires direct contact with infected blood or bodily fluids to spread. In regions where it occurs, transmission is frequently linked to specific local burial customs or direct care for the sick, rather than casual contact in public settings like airplanes. Experts clarify that an infected person who is not yet symptomatic poses no risk to fellow travelers.

Similarly, hantavirus is primarily contracted by inhaling particles from the urine, feces, or saliva of infected rodents. While a rare strain known as Andes has demonstrated limited human-to-human transmission, it requires prolonged close contact in enclosed spaces. Even in instances like the cruise ship outbreak on the MV Hondius, the number of confirmed cases remained low despite the close living quarters of passengers.

Did You Know? Over a 30-year period ending in 2023, only 890 cases of common hantavirus were reported in the United States, according to the centres for Disease Control, and Prevention.

Prioritizing Public Health Vigilance

As the upcoming World Cup approaches, health officials are shifting their focus from rare, exotic threats to more common, highly transmissible viruses. Large-scale gatherings in crowded stadiums present a potential environment for the spread of respiratory viruses, including influenza, COVID-19, and RSV, as well as childhood illnesses like measles.

Measles, in particular, remains a significant concern due to declining vaccination rates in the U.S., Canada, Mexico, the U.K., and parts of Europe. Infectious disease specialists suggest that an unvaccinated individual could potentially trigger local outbreaks by introducing the virus to undervaccinated communities. Pediatric vaccination rates for influenza have seen a decline of approximately 10% since 2019, contributing to higher mortality rates among children.

Expert Insight: The distinction between global headlines and daily health risks is critical. While exotic viruses dominate the news cycle, the actual public health burden is driven by preventable diseases. Prioritizing routine vaccinations and hygiene practices remains the most effective strategy for individual safety, especially as large-scale events like the World Cup could facilitate the spread of more common, yet impactful, pathogens.

Protective Strategies

Experts recommend a back-to-basics approach to personal safety. Consistent handwashing with soap and water remains the primary defense against viral and bacterial transmission. Using sanitizer on high-touch surfaces like grocery cart handles and avoiding touching one’s face can significantly reduce exposure risk.

For those at higher risk—including the immunocompromised, the elderly, pregnant individuals, and young children—wearing an N-95 mask in crowded settings during peak viral seasons is advised. When travelling internationally, maintaining caution regarding food and water consumption—specifically adhering to the rule of cooking, peeling, or boiling—can help prevent diarrheal diseases.

Frequently Asked Questions

Should I be worried about catching Ebola while travelling?
No. Ebola is not spread through casual contact and requires direct exposure to the bodily fluids of a symptomatic, seriously ill person. Asymptomatic individuals on planes pose no risk to others.

What is the most effective way to prevent the spread of common viruses?
Experts highlight that staying up to date on all recommended vaccinations, practicing frequent handwashing, and using N-95 masks in crowded, enclosed spaces are the most effective ways to protect yourself.

Why are experts concerned about the upcoming World Cup?
Large, crowded events in confined spaces can create “mass contamination” scenarios for common respiratory and intestinal viruses. The risk is compounded by declining vaccination rates for diseases like measles and influenza, which could be inadvertently spread by attendees.
