Influenza Causes in Adults and Children
Influenza causes by virus that can be transmitted either directly or indirectly. One example of direct transmission is when we inadvertently breathe saliva in the air released by a flu patient through sneezing or coughing. Another example of direct transmission is when we shake hands with flu sufferers after their hands hold their mouth or nose.
Indirect transmission is generally mediated by objects that have been contaminated with the virus. We can become infected by the flu when it holds the surface of an object that has been affected by sprinkling of saliva. The flu virus can survive on the surface of the object for one day. Examples of objects that are often the medium of transmission of flu viruses are door handles, telephones, or computer keyboard.
