Guidelines & Recommendations

This joint document serves to update the California Department of Public Health (CDPHⁱ) recommendations of August 20, 2009, for infection control for 2009 H1N1 influenza in health care settings based on the revised Centers for Disease Control and Prevention (CDC) “Interim Guidance on Infection Control Measures for 2009 H1N1 Influenza in Healthcare Settings, Including Protection of Healthcare Personnel,” issued October 14, 2009.

CDPHⁱ is revising the 2009 H1N1 influenza infection control suspect case definition. This revision reflects the current decreased prevalence of 2009 H1N1 influenza relative to other respiratory pathogens that produce a clinical illness similar to that of both 2009 H1N1 and seasonal influenza

Provides guidance for hospitals and other health care facilities and local health departments on regulatory requirements from the State Fire Marshal and the Office of Statewide Health Planning and Development (OSHPD) for tents used to accommodate a surge in demand for health care.

Example of steps to take for safe redonning (reuse) of N95 respirators. N95s may be reused until crushed, soiled, wet or difficult to breathe through.

This set of Questions and Answers was initially issued by FDA in July 2009. Due to the evolving nature of the 2009 H1N1 public health emergency, FDA has amended the original Emergency Use Authorizations (EUAs) for both Tamiflu and Relenza. The Updated Questions and Answers reflect the information in the amended EUAs.

CDPHⁱ Issued an H1N1 Health Alert with information on the following issues:

1. Access to IV Peramivir under Emergency Use Authorization
2. 2009 H1N1 influenza infection among pregnant women
3. Reporting of adverse events temporally associated with influenza vaccine
4. Testing of severely ill or fatal cases of suspect 2009 H1N1 influenza
5. Referral of specimens to VRDL for influenza testing
