The Centers for Disease Control and Prevention (CDC) has released specific recommendations for dental healthcare professionals to prevent transmission of the 2009 H1N1 Influenza virus.
Viral transmission is thought to occur through droplet exposure of mucosal surfaces; through indirect contact, usually via the hands, with respiratory secretions from an infectious patient or contaminated surface; and through inhalation of small particle aerosols in the vicinity of the infectious individual.
The US authority encourages all dental healthcare personnel to receive seasonal influenza and 2009 H1N1 influenza vaccinations. They should also continue to self-assess daily for symptoms of febrile respiratory illness (fever plus one or more of the following: nasal congestion/runny nose, sore throat, or cough), and not attend work until at least 24 hours after they are free of fever.
The CDC has also made several recommendations regarding how to deal with patients with flu-like symptoms, using an airborne infection isolation (All) room, what personnel should wear (including disposable N95 respirator if the patient has suspected or confirmed 2009 H1N1 influenza), and how to minimise spreading the virus.
Detailed information can be found in CDC's Interim Guidance on Infection Control Measures for H1N1 Influenza in Healthcare Settings, Including Protection of Healthcare Personnel.
