Signs of Swine Flu in Infants

Swine flu, H1N1 or influenza A, is a novel form of the flu that was first identified in April 2009, per the Centers for Disease Control and Prevention (CDC). They point out that little is known about how this virus impacts children. Based on historical evidence, children under the age of five have experienced the greatest rate of complications with seasonal influenza and other pandemics. Early intervention, prevention and vaccination can decrease the risk of infection in children and adults. According to the CDC, a test is the only way to diagnose the infection of H1N1.

Early Signs

Like a cold, the flu can begin with sneezing, coughing, nasal congestion, headache and sore throat. According to the CDC, infants and children are less likely to have a cough or fever with the flu. A sudden onset of symptoms followed by improvement and then a sudden decline in health may signify swine flu infection. Alone, these early signs may not be recognized as the flu, but as the infection progresses, it may become clearer.

Evident Signs of the Flu

A high fever, body or muscle aches, lethargy, chills or breathing difficulties are several symptoms of the flu that typically are not associated with the common cold or simple illnesses. A body temperature above 101 degrees F should be brought to your doctor's attention. Depending upon the age of the child, immediate medical attention may be necessary or a fever-reducing medication approved by the doctor. Signs of muscle pain in infants may be seen when a baby squirms when being held. An infant that fails to wake up or seems unresponsive to noise or being roused should receive medical attention immediately. Flu.gov points out that some children have experienced vomiting and diarrhea with the flu.

Special Considerations for Infants

Infants have an immature immune system that can easily be overwhelmed with an infection such as swine flu. Existing health concerns such as asthma or immune deficiency can increase the risk of complications from H1N1 infection. These infants are high on the priority list for vaccination, per the CDC. A rash, blue tint to the skin or rapid breathing are symptoms that require immediate medical attention. They are often associated with H1N1 but may indicate some other serious illness.
