Transcript

  • 1. Outbreaks of Influenza Linked to Changes of Absolute Humidity Emma Gillam and Angelique Ogilvie
  • 2. Influenza
      • Influenza is a highly contagious airborne disease. 
      • It is a result of an infection from one of the three basic types of influenza- A, B, or C. 
      • The cause of influenza is single stranded RNA viruses that infect the respiratory tract. 
  • 3. Symptoms
      • Patients with influenza frequently show symptoms shared by many other viral diseases.
      • Influenza onset is usually very abrupt and acute.
      • The symptoms of influenza include
        • fevers ranging from 100-104 degrees Fahrenheit
        • sore throat
        • cough and other respiratory symptoms
        • muscle pains
        • severe headaches
        • weakness and fatigue
  • 4. Outbreaks of Influenza
      • Every year the peak of influenza outbreaks is during the winter.
      • The seasonal increase of influenza that has baffled scientists because they could not discover the cause of the increase in outbreaks.
      • A new study has found that the wintertime peak of outbreaks of influenza is caused by seasonal changes of absolute humidity.
  • 5.               Outbreaks On Influenza
      •   Absolute humidity quantifies the actual amount of water in the air, regardless of the temperature.
      • 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.
      • Drier weather helps the influenza virus survive in the air.
      • 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.
  • 6.                         Significance
      • This information does not predict were influenza will strike because that also depends on other variables, such as population and person-to-person interactions.
      • However, scientist believe that this information can be used to help plan strategies of how to stop influenza before outbreaks appear.
      • This data will be useful in containing outbreaks of influenza and it the future it could lead to preventing the outbreaks before they happen.
