Most people experience several bouts of influenza throughout their lifetime. According to the Centers for Disease Control and Prevention (CDC), even otherwise healthy people can get sick enough to require hospitalization from the flu.
The flu is an infection of the respiratory tract that is caused by the influenza virus. It is spread mainly through airborne transmission, when an infected person sneezes, coughs or speaks. A person can infect others one day before having flu symptoms and up to five days after becoming ill.
Influenza is most often associated with the sudden onset of fever, headache, fatigue, muscle aches, congestion, cough and sore throat. Most people recover within a few days to less than two weeks. Occasionally, complications such as pneumonia, bronchitis or other infections can occur.
The flu vaccine is your best chance of preventing the illness. Currently, the CDC recommends that anyone over 6 months of age receive an annual flu shot. Nasal sprays and egg-free vaccines are also available. While there are many different types of flu virus, the shot protects you against the viruses that experts believe will be most common that year.
Doctors highly recommend that those at high risk for flu complications—young children, pregnant women, people with certain chronic conditions (asthma, diabetes, etc.) and those 65 years or older—should get the vaccine each year.
