The CDC has consolidated its respiratory virus guidance for healthcare workers into a single document covering SARS-CoV-2, influenza, and RSV — but dental practices are explicitly excluded from the update. Here is what Ontario dental practices should review in their own infection prevention protocols as 2026 draws to a close.
As of September 2026, the Centers for Disease Control and Prevention (CDC) released an updated section within its Infection Control in Healthcare Personnel: Epidemiology and Control of Selected Infections Transmitted Among Healthcare Personnel and Patients document. The new viral respiratory infections section brings SARS-CoV-2, seasonal influenza, and respiratory syncytial virus (RSV) recommendations under one roof, replacing the previous pathogen-by-pathogen approach that had developed over multiple pandemic-era updates.
For dental professionals in Ontario and across Canada, the headline is straightforward: this update introduces no new infection control requirements for dental settings. The CDC maintains a separate guidance pathway for dentistry, and the consolidated respiratory virus document explicitly excludes dental practitioners from its scope.
That said, the ADA recommends treating this moment as a prompt to audit your own protocols — particularly employee health policies, vaccination documentation, and return-to-work procedures.
What the CDC Actually Changed
According to reporting by ADA News on September 25, 2026, the CDC added a new viral respiratory infections section to its healthcare personnel infection control resource. The update supersedes previous return-to-work recommendations that had been issued separately for SARS-CoV-2 and seasonal influenza. By folding these into a single unified framework, the CDC aims to simplify compliance for general healthcare settings.
The three respiratory viruses now covered under this consolidated guidance are:
- SARS-CoV-2 — the virus responsible for COVID-19
- Influenza — seasonal flu strains
- RSV (Respiratory Syncytial Virus)
The consolidation reflects a broader CDC strategy of moving away from emergency-era, pathogen-specific directives toward standing operational guidance that healthcare facilities can maintain year-round.
Why Dental Practices Are Excluded — and What That Means
Dental settings have their own CDC infection prevention framework: the Summary of Infection Prevention Practices in Dental Settings: Basic Expectations for Safe Care. This document, maintained separately by the CDC, covers the unique aerosol-generating procedures, instrument reprocessing requirements, and patient-contact patterns specific to dentistry.
The exclusion of dental practices from the updated respiratory guidance does not mean respiratory viruses are irrelevant to your clinic. It means the CDC considers dental-specific protocols — which already incorporate Standard Precautions, PPE selection for aerosol-generating procedures, and environmental cleaning standards — to be the appropriate framework for managing these risks in dental settings.
What the ADA Recommends Dental Employers Do Now
While no new regulatory requirements apply to dental practices, the ADA suggests this is a practical moment for dental employers to:
- Update employee health policies — ensure your written occupational health protocols reflect current best practices, not pandemic-era emergency rules that may no longer apply
- Review vaccination and immunity documentation — confirm that immunization records are current for all clinical staff
- Establish or refresh exposure response and illness reporting protocols — define clear steps for when a team member reports respiratory symptoms or a known exposure
- Create return-to-work procedures — document criteria for when staff who have been ill with a respiratory infection can safely return to patient care
- Align practices with dental-specific CDC recommendations — use the Summary of Infection Prevention Practices in Dental Settings as your primary reference point
- Educate team members about policy changes — ensure front-desk, clinical, and sterilization staff all understand updated protocols
Pro Tip: Schedule a 30-minute team meeting before year-end specifically to walk through your updated employee health policy. Assign one team member to verify that every clinical staff member's vaccination records are current and filed. This single action addresses the ADA's top recommendations and creates a documented compliance record for your practice.
Implications for Ontario and Canadian Dental Practices
Canadian dental practices operate under provincial regulatory bodies. In Ontario, the Royal College of Dental Surgeons of Ontario (RCDSO) sets infection prevention and control (IPAC) standards. While the CDC update does not directly apply to Canadian practices, many Canadian dental professionals and regulators reference CDC guidance as part of their own evidence-based approach to infection prevention.
Ontario dental practices should focus on these areas as the year closes:
- IPAC program annual review — the RCDSO expects practices to maintain a comprehensive IPAC program. This is a natural time to verify your sterilization monitoring logs, biological indicator (spore test) results, and instrument reprocessing documentation are complete and accessible.
- Staff immunization records — verify that all clinical staff vaccination and immunity documentation is current and properly filed
- Sterilizer monitoring — the CDC recommends biological indicators at least weekly. Confirm your practice meets this standard and that results are properly logged. Dental handpieces should always be heat sterilized between patients — this is a non-negotiable baseline.
- Instrument classification compliance — verify your reprocessing protocols correctly distinguish between critical instruments (those that penetrate soft tissue or bone, requiring heat sterilization), semicritical instruments (contacting mucous membranes, also requiring heat sterilization), and noncritical items (contacting intact skin only, requiring cleaning and EPA-registered disinfection)
Pro Tip: Build a one-page year-end IPAC audit checklist that your designated IPAC coordinator can complete in under an hour. Include: spore test log completeness, chemical indicator supply levels, handpiece sterilization protocol confirmation, and staff vaccination record status. File the completed checklist with your annual IPAC documentation.
The Broader Context: September Is Dental Infection Control Awareness Month
This CDC update arrives during Dental Infection Control Awareness Month, observed every September. The Association for Dental Safety's 2026 theme is "Safety Starts with Every Step," reinforcing that infection prevention is a continuous, process-driven discipline rather than a set of one-time compliance checkboxes.
The timing makes this an opportune moment to review not just employee health policies but the full spectrum of infection prevention practices — from instrument reprocessing and environmental surface disinfection to waterline management and sharps safety.
What This Means Going Forward
The CDC's move toward consolidated, standing guidance signals a permanent shift away from the emergency-response posture of the pandemic years. For dental practices, this reinforces a message that has been consistent since the CDC first published its dental-specific infection prevention summary: dentistry's infection control framework is mature, well-defined, and maintained on its own track.
The practical takeaway for Ontario dental practice owners and IPAC coordinators: use the final quarter of 2026 to confirm your protocols are current, your documentation is complete, and your team is trained. No new rules apply — but the standards that already exist deserve a fresh look before the year turns.
EBIKO Dental will continue monitoring CDC, ADA, and RCDSO infection prevention updates as they develop.

Frequently Asked Questions
Q: Does the September 2026 CDC respiratory virus guidance update change infection control requirements for dental practices?
No. The CDC's updated respiratory virus section within Infection Control in Healthcare Personnel explicitly excludes dental settings. Dental practices continue to follow the CDC's separate Summary of Infection Prevention Practices in Dental Settings. No new regulatory requirements were introduced for dental practices as part of this update.
Q: What should Ontario dental practices do in response to this CDC update?
While no new rules apply, the ADA recommends dental employers use this as a prompt to update employee health policies, verify staff vaccination records, establish or refresh exposure response protocols, and create documented return-to-work procedures for team members recovering from respiratory infections. Ontario practices should also verify their RCDSO IPAC compliance documentation is current.
Q: How often should dental practices run biological indicator (spore) tests on their sterilizers?
According to the CDC's dental-specific infection prevention guidance, biological indicators should be used at least weekly to monitor sterilization equipment. Many provincial regulatory bodies and dental associations recommend the same minimum frequency. Results should be logged and retained as part of your practice's IPAC documentation.
