Transmission - H1N1
 * Symptoms are similar to the seasonal influenza virus and include: fever, cough, headache, muscle and joint pain, fatigue and runny nose. Some people also experience diarrhea, vomiting and neurological
 * Those under 5, over 65 or pregnant are more susceptible to becoming infected as well as anyone else with a weakened immune system
 * “More than 70% of hospitalizations in the U.S. have been people with...underlying conditions" (Center for Disease Control and Prevention)
 * H1N1 has an incubation period lasting anywhere from 1 to 7 days, but most often symptoms start within the first 1-4 days after exposure
 * Those infected are considered contagious for 7 days after they start showing symptoms. If symptoms don't subside after 7 days, the infected person in considered contagious until they are no longer showing any symptoms
 * H1N1 can be deadly, however, it is less lethal and less severe in most cases than the traditional influenza virus. Those that did die during the 2009 pandemic in most cases had other underlining illnesses which impaired their immune response allowing their infection to become severe.
 * A severe case of H1N1 has different symptoms for adults than for children
 * The symptoms of a severe case of H1N1 in an adult include: difficulty in breathing/shortness of breath, chest pain, sudden dizziness, confusion, vomiting, and a low temperature.
 * The symptoms of a severe case of H1N1 in a child include: fast breathing, bluish skin color, dehydration, over sleeping, irritability, regular flu symptoms, rash, inability to eat, and a lack of tears when crying
