Influenza The Past, Present, and Future Flu
-Last 1-2 weeks
-Contagious for one day prior to appearance of symptoms
-Contagious 5-7 days after appearance of symptoms Cold
-Lasts around one week
-Contagious for first 3 days How Contagious Is It? Flu
Severe body aches
Dry cough
Extreme exhaustion
Chills Cold
Runny nose
Runny eyes
Mucus-producing cough
Sore throat Present Chris Costin, Jamie Luster, Jauna Gordon,
Laura Wilson, Poornima Venigalla, Sarah McBane, Sarah Swager, Stephanie Johnson How Is It Spread? Spread through the air via droplets
Sneezing, coughing and talking
Six feet range
Less commonly spread by touching doorknobs, pencils, keyboards, etc.
*Card Demonstration* Preventative Measures •Wash hands
•Use proper technique when sneezing and
•Don’t reuse Kleenex
•Get plenty of rest •Reduce sugar intake
•Wheatgrass •Drink more water
•Dark leafy greens
•Chicken soup
•Hot tea
•Bananas Natural Remedies Future Quadrivalent Vaccine Previous vaccines=Trivalent Cold vs. Flu Who Is At Risk? 200,000 hospitalized
10% are children
In Ohio, 15.4 people out of every 100,000 die from influenza
100,000 people visit Ohio State daily
90% of flu-related deaths are people 65+ years.
100 kids die of flu each year in U.S. 2012-13 Flu Season and Vaccine -Flu seasons are unpredictable in length and severity.
-Started 5 weeks early this year
-Usual peak season is between November and March.
-The CDC identifies when, where, and what strain.
-Three different types of flu virus:
H3N2, Influenza B, H1N1
H3N2 is the most severe and is the common strain this year. New vaccine available for the 2013-2014 flu season= Quadrivalent
Guards against two A strains and two B strains
In 6 of the last 11 flu seasons, experts predicted the wrong B strain .
Victoria lineage or Yamagata lineage. SOLUTION: vaccinate both. Who Should
Be Vaccinated? 6 months and older
Pregnant women
Adults over 50
American Indians and Alaskan Natives
Seem to be at higher risk of flu complications
People with chronic medical conditions Universal Vaccine A Universal vaccine effective against nearly all flu strains is in the works. Targets the surface protein hemagglutinin A
Highly conserved protein across many flu strains
High efficacy in mice and rabbit trials
Human trials in the future Influenza will always be lurking. . . Influenza has an unstable exterior and changes erratically.
Changes lead to poor human immune responses
Vaccines predicted and made by CDC nine months before the flu season starts are often ineffective.
Pandemics may occur when novel flu virus appears - novel coat
If a new flu such as a virulent H5Nx (bird flu) or a novel HXNX flu materialized, we could see a huge pandemic.

Virus was first isolated in the lab in 1932. Since then they've been able to track the history of the infection. History of Outbreaks Pandemic vs. Epidemic Influenza was not recognized in North America until Europeans first visited.
