CDC HAN: Health Update Regarding Treatment of Patients with Influenza with Antiviral Medications1/9/2015
Date Sent: 01/09/2015 04:32 PM EST Sender: Michigan Health Alert Network Subject: CDC HAN: Health Update Regarding Treatment of Patients with Influenza with Antiviral Medications Message:
Widespread influenza activity is being reported in most U.S. states, with influenza A (H3N2) viruses most common. H3N2-predominant flu seasons have been associated with more hospitalizations and deaths in older people and young children in the past. In addition, approximately two-thirds of H3N2 viruses that have been tested at CDC are antigenically or genetically different from the H3N2 vaccine virus. This difference suggests that vaccine effectiveness may be reduced this season. High hospitalization rates are being observed, similar to what was seen during the 2012-2013 influenza season. Hospitalization rates are especially high among people 65 years and older. In this context, the use of influenza antiviral drugs as an adjunct to vaccination becomes even more important than usual in protecting people from influenza. Antiviral medications are effective in treating influenza and reducing complications. Antivirals are available and recommended, but evidence from the current and previous influenza seasons suggests that they are severely underutilized. This CDC Health Update is being issued to: 1) Remind clinicians that influenza should be high on their list of possible diagnoses for ill patients, because influenza activity is elevated nationwide, and 2) Advise clinicians that all hospitalized patients and all high-risk patients (either hospitalized or outpatient) with suspected influenza should be treated as soon as possible with one of three available influenza antiviral medications. This should be done without waiting for confirmatory influenza testing. While antiviral drugs work best when given early, therapeutic benefit has been observed even when treatment is initiated later. Please refer to CDC HAN: 375 attached to this alert for more information. ## This message is being sent to the following statewide roles: Communicable Disease / Infection Prevention | Emergency Preparedness | Epidemiology | Healthcare | Physician / Medical Director ## Attachments: Comments are closed.
