The swine flu, caused by the H1N1 virus, was declared a global pandemic in 2009 by the World Health Organization. The swine flu H1N1 virus is a Type A influenza virus, similar to the standard human flu viruses. The symptoms of swine flu are therefore also similar to normal seasonal flu symptoms. The swine flu, however, can also cause more serious illness in both children and adults, so the following signs should be closely monitored.
General Flu Symptoms
Infection with the H1N1 virus, resulting in swine flu, can cause a variety of symptoms. The most common symptoms include fever, chills, body aches, headache and fatigue. The swine flu is a respiratory virus and can therefore also cause cough, sore throat and runny nose. Some patients may also exhibit gastrointestinal symptoms including nausea, vomiting and diarrhea.
These symptoms of swine flu usually begin three to five days after exposure to the virus, according to the Mayo Clinic. The swine flu spreads very rapidly and can be spread to another person even before you exhibit signs of the illness. The symptoms last approximately eight to 10 days.
Serious Symptoms in Children
The swine flu can escalate into a serious illness. Often children will show signs of recovery with flu symptoms seeming to get better but then returning with a worse cough and higher fever. Children may have difficulty breathing or their breathing may be faster than usual. This can result in a bluish color to their skin. Children may also develop a rash with their fever and may become so irritable they refuse to be held or become inconsolable. The most alarming sign of a serious swine flu infection is when the child is unable to wake up or interact with the environment.
Serious Symptoms in Adults
Adults can also develop a serious swine flu infection. Patients may feel short of breath or have trouble breathing. This can lead to dizziness and confusion. The presence of uncontrollable vomiting is another serious symptom. This may be accompanied by pain or pressure in the chest or abdominal area.
Pneumonia
An H1N1 infection can also lead to the development of pneumonia. Pneumonia is an infection in the lungs that causes the air sacs (the alveoli) to become inflamed. As the air sacs fill with fluid, the production of phlegm increases, resulting in productive coughs. Pneumonia can cause trouble breathing and even lead to respiratory failure if treatment is not received.
