H1N1: Facts and Figures

• On July 24, 2009 official reporting of individual cases of confirmed and probable novel H1N1 infection was discontinued.

• From April 15, 2009 to July 24, 2009, states reported a total of 43,771 confirmed and probable cases of novel influenza A (H1N1) infection. Of these cases reported, 5,011 people were hospitalized and 302 people died.

H1N1: Facts and Figures• It is estimated that more than one million people

became ill with novel H1N1 flu between April and June 2009 in the United States.

• Epidemiologic field studies in several states found a secondary attack rate in household contacts for acute-respiratory-illness (ARI) was 18 % to 19% and 8% to 12% for influenza-like-illness (ILI). ARI is defined as two or more of the following four symptoms: fever, cough, sore throat, and rhinorrhea (runny nose). ILI is defined as fever and cough or sore throat.

SHS H1N1 Influenza Plan

• Students will be encouraged to call if they have influenza-like symptoms

• Rapid Influenza Testing may be done, but this method will not be used to rule out H1N1 influenza.

• We continue as a sentinel physician site, so samples can be sent through that process for testing at the State lab.

SHS H1N1 Influenza Plan

• The “official” CDC position is that individuals with H1N1 influenza without high risk medical conditions do not need treatment.

• Treatment for H1N1 is with Tamiflu or Relenza• The Student Health Service will offer

treatment for students diagnosed with H1N1 influenza who also have medical conditions that place them at risk for complications if they acquire H1N1 influenza.

SHS H1N1 Influenza Plan

• We anticipate H1N1 influenza vaccine will be available in mid to late October. The Benson Center has been reserved for November 3rd and 4th for this.

• The seasonal influenza vaccine clinics for students are scheduled for September 23-24.

• The seasonal influenza vaccine clinics for faculty/staff are scheduled for mid-October.
