Best Practices for Disinfection During Flu Season and Emerging Health Risks

Flu season and emerging health threats place added pressure on facilities to maintain safe, hygienic environments. Effective disinfection requires more than increasing cleaning frequency—it demands a targeted, evidence-based approach.

Focus on high-touch, high-risk areas. Not all surfaces carry the same level of risk. Door handles, elevator buttons, restrooms, break rooms, shared equipment, and reception areas require prioritized attention. Disinfection protocols should be adjusted to increase frequency in these areas without disrupting normal operations.

Use the right products—and use them correctly. Cleaning chemicals and disinfectants are only effective when used according to manufacturer guidelines. This includes proper dilution, dwell time, and surface compatibility. Using the wrong product—or rushing the process—can reduce effectiveness and create a false sense of security. All products and chemicals should either meet or exceed the EPA’s published guidelines or have been certified by Green Seal, EcoLogic, or the U.S. Green Building Council in order to minimize the negative impact on public health and the environment.

Balance routine cleaning with enhanced protocols. Daily cleaning removes dirt and debris, which is essential for disinfectants to work properly. During flu season, facilities should layer enhanced disinfection on top of routine cleaning rather than replacing it. This balanced approach ensures both cleanliness and pathogen reduction.

Train teams on evolving health guidance. Health risks change, and cleaning protocols must evolve with them. Ongoing training helps janitorial teams understand when and how to escalate disinfection efforts, recognize contamination risks, and follow updated safety procedures without overusing chemicals.

Communicate clearly with occupants. Visible cleaning efforts and clear communication reassure occupants that health risks are being addressed. Posting cleaning schedules or providing brief updates can improve confidence and encourage shared responsibility, such as hand hygiene and respectful use of shared spaces.

By adopting a strategic, informed approach to disinfection, facilities can protect occupants, reduce absenteeism, and maintain trust during periods of heightened health concern.
