The 2009 H1N1 flu, commonly called swine flu, is a viral respiratory infection that usually resolves on its own but can occasionally cause severe illness and death. In 2009, the World Health Organization declared the 2009 H1N1 flu a worldwide pandemic. It is important to know the symptoms of this flu so that you can seek treatment if necessary and avoid spreading it to others.
Fever and Malaise
Most people with the H1N1 virus experience a fever, but the Centers for Disease Control (CDC) states that not all sufferers have an elevated temperature. Along with a fever, according to the Mayo Clinic, chills and muscle aches are common. People with the swine flu may feel overwhelmingly tired and fatigued, and may lack the energy to do anything.
Coughing/Runny Nose
According to the CDC, respiratory symptoms, such as coughing and a runny or stuffy nose, are common with this illness. A sore throat may also be present. People with asthma, chronic lung diseases, heart disease and diabetes are more at risk for respiratory complications. These may include pneumonia and respiratory failure.
Nausea and Vomiting
While influenza does not typically cause nausea, vomiting and diarrhea in adults, the H1N1 virus does cause digestive disturbances in some people. If you experience severe vomiting, the CDC recommends that you seek medical care promptly.
Severe Symptoms
The CDC lists symptoms that require emergency medical attention as difficulty breathing, chest pain, dizziness and confusion. Children may be at increased risk from this illness. Symptoms that require urgent care in children include bluish skin color, lethargy, extreme irritability, rapid breathing and a fever with a rash.
