Interim Guidance for Clinicians &
Public Health Professionals

Clinicians

Clinicians should consider the possibility of swine influenza virus infections in patients presenting with febrile respiratory illness.

If H1N1 flu is suspected, clinicians should obtain a respiratory swab for H1N1 influenza testing and place it in a refrigerator (not a freezer). Once collected, the clinician should contact their state or local health department to facilitate transport and timely diagnosis at a state public health laboratory.

State Public Health Laboratories

Laboratories should send all unsubtypable influenza A specimens as soon as possible to the Viral Surveillance and Diagnostic Branch of the CDC’s Influenza Division for further diagnostic testing.

Public Health and Animal Health Officials

Officials should conduct thorough case and contact investigations to determine the source of the H1N1 influenza virus, extent of community illness and the need for timely control measures.

Always follow your standing/written orders or SOP's.
