Revisión del 13:17 12 mar 2011

High-risk groups

Pregnant- incr rates of SAB, preterm labor
Chronic lung disease
Immunosuppressed
Cardiac
DM

Screening

Individuals with an acute febrile respiratory illness (a measured temperature of 100ºF or higher and recent onset of at least one of the following: rhinorrhea, nasal congestion, sore throat, or cough) or sepsis-like syndrome- HIGH PRIORITY for hospitalized patients and those at high-risk for severe disease.

Diagnosis

Rapid Flu nasal swab 60-80% sensitive in detecting influenza A
If patient is negative, severely ill and will be hospitalized, send viral culture
PCR is the recommended confirmatory test

Treatment

All hospitalized patients with confirmed, probable or suspected novel influenza (H1N1)
Patients who are at higher risk for seasonal influenza complications

Most effective when started within 48 hours of illness onset.

Adult: 75-mg capsule twice per day for 5 days

Post-exposure chemoprophylaxis

Tamiflu 75mg po daily x 10 days (10 days after the last known exposure to novel (H1N1) influenza.)

If the contact occurred with a patient after 7 days of symtpom onset, then chemoprophylaxis is not necessary. This is the presumed post-infectious period.

--June 11, 2009, WHO raised its pandemic alert level to the highest level, phase 6, indicating widespread community transmission on at least two continents.

-Post-exposure antiviral chemoprophylaxis is recommended for those with close contacts:
-Tamiflu 75mg po daily x 10 days (10 days after the last known exposure to novel (H1N1) influenza.)
 If the contact occurred with a patient after 7 days of symtpom onset, then chemoprophylaxis is not necessary. This is the presumed post-infectious period.
