Swine influenza, known as H1N1, made headlines in the Spring of 2009. Normally a respiratory infection found in pigs, this influenza virus strain passed to humans and created a worldwide scare.
History
The swine flu first emerged among pigs during the human influenza pandemic of 1918. Pigs acquired human influenza and displayed their own flu-like symptoms, thus creating a new strain of influenza, informally called swine flu. In 1979, the swine flu was found in humans among soldiers at Fort Dix, New Jersey.
Symptoms
According to MayoClinic.com, swine flu symptoms include fever, cough, headache, fatigue, chills, body aches vomiting or diarrhea.
Cause
Influenza has many strains that mutate over time. Human, pig and avian strains are unique to these species, but when a virus mutates, it can then cross species and create worldwide havoc.
Modes of Transmission
Swine influenza is contagious. It is passed through H1N1 virus-infected respiratory droplets of saliva and nasal secretions. Coughing, sneezing and touching infected surfaces are ways in which the virus spreads.
Treatment
According to MayoClinic.com, Tamiflu and Relenza are antiviral medications that can treat swine influenza.
Prevention/Solution
Wash your hands and stay home if you are sick. A vaccine is also available and is recommended for pregnant women, children, young adults, people with severe illnesses and healthcare workers.
