Influenza Prevention and Control, 2012-2013
  • Vaccinate everyone aged 6 months and older against influenza.

  • Vaccinate day care and school-aged children, who are key transmitters of disease, as early as possible.

  • Give inactivated vaccine to all pregnant women in any trimester.

  • Vaccinate all health care workers against influenza.

  • New health care worker vaccination reporting requirements for acute-care facilities will take effect in January 2013.


Antiviral agents are used for treatment of influenza-infected individuals and are most effective in reducing the severity of illness when administered within 48 hours after illness onset (47). Oseltamivir (Tamiflu®) capsules and oral suspension and zanamivir (Relenza®) oral inhalation are active against influenza A and B viruses. They may also be used as chemoprophylaxis for health care workers and people at higher risk for complications, if they are not vaccinated (eg, vaccine is medically contraindicated) (47). Two other antiviral agents, amantadine (Symmetrel®, Symadine®) and rimantadine (Flumadine®), are active only against influenza A viruses and are not recommended for treatment or prophylaxis of currently circulating viruses due to drug resistance (47).
