Outbreaks Of Influenza Linked To Changes Of Ab

  1. 1. Outbreaks of Influenza Linked to Changes of Absolute Humidity Emma Gillam and Angelique Ogilvie
  2. 2. Influenza <ul><ul><li>Influenza is a highly contagious airborne disease.  </li></ul></ul><ul><ul><li>It is a result of an infection from one of the three basic types of influenza- A, B, or C.  </li></ul></ul><ul><ul><li>The cause of influenza is single stranded RNA viruses that infect the respiratory tract.  </li></ul></ul>
  3. 3. Symptoms <ul><ul><li>Patients with influenza frequently show symptoms shared by many other viral diseases. </li></ul></ul><ul><ul><li>Influenza onset is usually very abrupt and acute. </li></ul></ul><ul><ul><li>The symptoms of influenza include </li></ul></ul><ul><ul><ul><li>fevers ranging from 100-104 degrees Fahrenheit </li></ul></ul></ul><ul><ul><ul><li>sore throat </li></ul></ul></ul><ul><ul><ul><li>cough and other respiratory symptoms </li></ul></ul></ul><ul><ul><ul><li>muscle pains </li></ul></ul></ul><ul><ul><ul><li>severe headaches </li></ul></ul></ul><ul><ul><ul><li>weakness and fatigue </li></ul></ul></ul>
  4. 4. Outbreaks of Influenza <ul><ul><li>Every year the peak of influenza outbreaks is during the winter. </li></ul></ul><ul><ul><li>The seasonal increase of influenza that has baffled scientists because they could not discover the cause of the increase in outbreaks. </li></ul></ul><ul><ul><li>A new study has found that the wintertime peak of outbreaks of influenza is caused by seasonal changes of absolute humidity. </li></ul></ul>
  5. 5.               Outbreaks On Influenza <ul><ul><li>  Absolute humidity quantifies the actual amount of water in the air, regardless of the temperature. </li></ul></ul><ul><ul><li>It is higher in the summer and lower in the winter- a typical summer day can have 4 times as much water in the air than a typical winter day. </li></ul></ul><ul><ul><li>Drier weather helps the influenza virus survive in the air. </li></ul></ul><ul><ul><li>The outbreaks are encouraged by anomalously dry weather conditions; many outbreaks of influenza were preceded by a period of weather that was drier than usual. </li></ul></ul>
  6. 6.                         Significance <ul><ul><li>This information does not predict were influenza will strike because that also depends on other variables, such as population and person-to-person interactions. </li></ul></ul><ul><ul><li>However, scientist believe that this information can be used to help plan strategies of how to stop influenza before outbreaks appear. </li></ul></ul><ul><ul><li>This data will be useful in containing outbreaks of influenza and it the future it could lead to preventing the outbreaks before they happen. </li></ul></ul>
  7. 7.                        Works Cited <ul><li>Sources: </li></ul><ul><li>http://www.sciencedaily.com/releases/2010/02/100222200847.htm?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+sciencedaily+(ScienceDaily%3A+Latest+Science+News)&utm_content=Netvibes http://emedicine.medscape.com/article/219557-overview http://www.medicinenet.com/influenza/article.htm </li></ul><ul><li>Images/Video: http://www.youtube.com/watch?v=01qwLckBLSM&feature=related http://www.ehs.ucr.edu/environmentalhealth/images/influenza.jpg http://risk.comm.cornell.edu/flu_vaccine.jpg http://bryanking.net/wp-content/uploads/2008/08/cold.jpg http://lib.store.yahoo.net/lib/allergybegone/humidity-lungs.gif </li></ul>
