Therapeutic approaches of clinicians to influenza pandemic.

In the event of influenza pandemic, clinicians have to be sure that vaccination has been correctly performed in all patients in whom it is usually recommended. Pregnant women should probably be vaccinated. Vaccination of health personnel is recommended to limit transmission of nosocomial influenza to high-risk persons, and to decrease the risk of absenteeism related to influenza. Chemoprophylaxis is effective in preventing influenza A, and is indicated in high-risk persons with major contraindication or impaired response to vaccination or who have not yet been vaccinated.
