PPT-Spatial Variation in Humidity and Influenza Across the US

submitted by Heidar Th Thrastarson Background amp Science Question Humidity has been shown to be a potentially important component of influenza transmission and has been used in models to predict seasonal outbreaks . While rare influenza can spread from pigs to people and from people to pigs When people get swine flu viruses its usually after contact with pigs This has happened in different settings including fairs Right now the Centers for Disease Control and P Chapters 4 and 5. 1. Class #3 July 9, 2010. Atmospheric Humidity. Chapter 4. 2. Class #3 July 9, 2010. Circulation of Water in the Atmosphere. A general definition of humidity is the amount of water vapor in the air.. ABSOLUTE HUMIDITY:. Absolute humidity (expressed as grams of water vapor per cubic meter volume of air) is a measure of the actual amount of water vapor (moisture) in the air, regardless of the air's temperature. The higher the amount (weight) of water vapor per kilogram, the higher the absolute humidity. . Trond . Reitan.

RNA enveloped viruses that make up three genera. Influenzavirus A. Influenzavirus B. Influenzavirus C. The type A viruses are the most virulent among the three, genetically diverse and infecting human, birds and animals. The influenza virus group consists of three enveloped RNA members of the family Orthomyxoviridae:. influenza A, B, and C. . Influenza A . viruses are further classified into hemagglutinin (H) and neuraminidase. Quan C, Wang Q, Zhang J, Zhao M, Dai Q, Huang T, et al.

Typically, influenza is characterized by fever, sore throat, chills and other non-specific symptoms, it is a much more severe disease. It is spread around the world in seasonal epidemics and according to World Health Organization, these annual epidemics result in about three to five million cases of severe illness, and about 250 000 to 500 000 deaths.. water vapor.  in the . air. . . Humidity. There are three main measurements of humidity: absolute, relative and specific.. Absolute humidity is the total amount of water vapour present in a given volume of air.. Vapour Pressure. , . Relative Humidity . and . Dew point temperature. .. . The partial pressure in air due to water vapour alone is called “vapour pressure”.. . It is expressed in energy units viz., millibar or millimetre of mercury..
