The influenza virus can affect people of all ages but those with diseases of the immune system and chronic illness are at increased risk. Because of their weakened immune system, the very young and the elderly are also at risk. Uncomplicated influenza presents with fever, headache, sore throat, cough, runny nose, and a general feeling of discomfort. The illness usually resolves after several days but the discomfort and cough may last weeks. The virus may cause worsening symptoms of underlying conditions such as asthma, heart disease, or lung disorders.
Influenza can also lead to a secondary bacterial pneumonia.
Most children and young adults develop a resistance to the virus after receiving the vaccine. The vaccine provides protection to the elderly, but because of compromised immune systems, is not guaranteed to prevent influenza. Optimal time for administering the vaccine is October through mid-November. Individuals at risk should consult their physician before receiving the vaccine to check for allergy or sensitivity to the components of the vaccine. Be watching for the State employee immunization schedule in the near future.
