Influenza, commonly known as the flu, is a contagious respiratory illness caused by viruses. It can cause mild to severe illness, and at times can even lead to death. Symptoms can range from mild to severe, and include fever, chills, body aches, sore throat, cough, fatigue, and headaches. Most people with the flu recover in a few days, but some can develop complications such as pneumonia, bronchitis, or sinus infections.
Swine flu, also known as the H1N1 virus, is an influenza A virus that is common in pigs and was first identified in humans in 2009. It is a highly contagious respiratory illness that can spread from person to person, through coughing or sneezing. The symptoms of swine flu are similar to those of the regular flu, including fever, chills, body aches, sore throat, and coughing. In addition, some people may experience vomiting, diarrhea, and fatigue. Complications can arise if the virus is not treated, and they can range from ear infections to pneumonia. Treatment typically includes antiviral drugs, and vaccinations are available.
Both influenza and swine flu are significant health risks that can be potentially life-threatening, and as such, it is important to take steps to protect oneself from infection. This includes avoiding contact with infected people, washing your hands regularly, and getting the flu vaccine annually.
