Hospital Infection Control in Hungary
Part of a Series: Read New technology boosts hospital infection control in Hungary – Part 1.
Traditional surface cleaning and hand hygiene protocols face major operational limitations in hospital settings. With bacterial pathogens recontaminating surfaces within hours and roughly one-third of healthcare-associated infections involving airborne transmission, facilities across Europe are expanding their strategy. Hospital networks in Hungary are adopting continuous air disinfection technologies to bridge the critical gap between routine surface wipes and indoor air safety.
The Limits of Hospital Surface Cleaning
Infection outbreaks are routinely traced to high-touch hospital surfaces: sinks, computer keyboards, supply carts, stretchers, IV poles, telephone handles, stethoscopes, blood pressure cuffs, ultrasound machines, ECG leads, and ventilators.
Expecting cleaning crews to continuously disinfect every surface across a facility is unrealistic. Staff face time constraints, varying training levels, and product limitations. Even under optimal protocols, surfaces rapidly recontaminate because airborne and human-borne pathogens return within hours.
An American study demonstrated that within 3 hours of disinfection, bacteria on hospital bed rails rebounded to unacceptable levels. Researchers noted that maintaining target non-detectable pathogen levels would require full disinfection approximately every two hours.
Bed Rail Transmission & Pathogen Persistence:
- Rapid Transfer: Studies show VRE bacteria transferred to gloved hands nearly half the time after contacting bed rails. Just 5 seconds of contact led to positive VRE handprint cultures 46% of the time.
- VRE Survival: Can survive up to 58 days on hospital countertops.
- C. difficile Spores: Can persist for 5 months on hospital floors, requiring only a few spores to infect vulnerable patients.
- Multi-Drug Resistant Organisms: MRSA, E. coli, Acinetobacter, and Klebsiella can remain viable on surfaces for over 300 days.
- Prior-Occupant Risk: Patients have a 40% elevated risk of contracting an MRSA infection when placed in a room previously occupied by an MRSA-positive patient.
As Scottish microbiologist Stephanie Dancer, M.D., noted in a review of surface cleaning strategies: “There is no easy way to clean a hospital or to keep it clean.”
Airborne Transmission: A Major Healthcare Challenge
Surface cleaning and hand hygiene address only part of the transmission equation. Research indicates that approximately one-third of all hospital-acquired infections involve airborne transmission — including MRSA, Acinetobacter, Clostridium difficile, influenza, and norovirus.
Routine activities such as coughing, sneezing, talking, breathing, and vomiting release infectious aerosols that hover in ambient air for hours before settling onto equipment or being directly inhaled.
- Aerosol Generation: A single vomiting episode can release at least 13,000 viral particles into the air, whereas as few as 20 particles can cause infection.
- Proximity Risk: Medical providers within 6 feet of influenza-infected patients face direct exposure to infectious viral doses through routine speech and breathing.
- Routine Care Aerosolization: Standard nursing actions like bed making and drawing privacy curtains launch C. difficile spores airborne.
Continuous Air Disinfection in Hungarian Hospitals
To mitigate airborne transmission, hospitals in Hungary and throughout Europe are installing Novaerus NanoStrike™ technology in patient wards, corridors, and high-risk surgical suites.
Unlike standard HEPA filtration — which traps but does not inactivate pathogens, posing exposure risks during filter replacements — NanoStrike technology inactivates airborne microbes directly. Operating continuously 24 hours a day, these units work independently of manual staff compliance and are certified safe for continuous exposure around vulnerable patients.
“This is the most effective and efficient technology, and we have the lab results to prove it,” states Gergely Szíjjártó.
Secondary Benefits: Odor Control and Indoor Environmental Quality
In addition to pathogen control, healthcare facilities report significant improvements in ward comfort and air quality.
“About 80% of hospital patients are in beds where there is no ventilation system (HVAC) installed in the ward and there is some kind of odor issue,” explains Szíjjártó. “The reduced odor is something doctors and nurses mention all the time — they love it.”
These systems also reduce airborne allergens and volatile organic compounds (VOCs). In basement pathology labs with restricted ventilation, continuous air disinfections lower ambient concentrations of formaldehyde, laboratory alcohols, and chemical reagents.
