Some of the most common symptoms of the H1N1 flu include development of a cough, fever, chills and a sore throat, according to WebMD. Individuals with the condition are also likely to develop a headache, body aches, nausea and vomiting. Most types of flu have similar symptoms which is why medical tests must be done to ascertain the exact strain.
The H1N1 flu is sometimes referred to as swine flu and became a pandemic in 2009, according to Flu.gov. Individuals that have visited a region with an outbreak of swine flu may be at a heightened risk of getting it, as are farmers and veterinary employees. Others with increased risk factors include individuals that are hospitalized, the elderly and infants, who may have weaker immune systems.
Individuals with the H1N1 flu can be contagious a day before any symptoms appear and remain contagious for an estimated 7 days. To prevent the condition from spreading, individuals should wash their hands frequently, avoid contact with the infected and contain coughs or sneezes. To treat this condition, doctors typically treat the symptoms associated with it, and if necessary, antiviral drugs are prescribed to contain symptoms, notes Mayo Clinic.
