1. Cases in the United States have presented clinically like regular ol' influenza with fever and respiratory tract illness (cough, sore throat, runny nose).
2. You have a probable case on your hands if the patient's rapid influenza test is positive for influenza A and the patient has been in contact with a confirmed (by PCR at public health lab) case within the previous 7 days or has traveled or lives in an area where there have been confirmed cases. However, given that the rapid influenza test is not 100% sensitive, even if it is negative for influenza A, the patient may still have swine flu particularly if s/he has been in contact with potential source patients. These patients are considered suspected cases.
3. Confirm probable and suspected cases by sending nasopharyngeal swab/aspirate or nasal wash/aspirate to public health lab.
4. Treat probable and suspected cases with oseltamivir or zanamivir. Dosing same as for regular flu.
5. Infection control procedures are essentially equivalent to those for regular ol' flu: contact and droplet precautions for 7 days following illness onset. Wash hands. Cover sneezes and coughs. Put face mask on patient and/or yourself. No need for special respirator mask unless in super long, super close contact with patient.
6. For the latest information on swine flu, chemoprophylaxis and more, check out the CDCs website.
