Three different types of flu viruses exist: types A, B & C. Most Americans who get the flu each year contract type A or type B flu. While types A & B are similar in the length and severity of symptoms, type C produces a less severe sickness. Type A flu is the only type that is capable of spreading from humans to animals. Type A flu is also responsible for most flu epidemics, because its virus is able to mutate quickly.
Symptoms of type A flu include cough, fever and chills, sore throat, congestion, headaches, and fatigue. These symptoms usually last between two to ten days. Those in high-risk groups, such as the elderly, pregnant women, and children, should notify their doctor immediately if they experience severe flu symptoms.
Patients should also seek medical attention if their flu symptoms get better but later return with a more severe cough and fever, notes the U.S. Department of Health & Human Services.
Those suffering from the flu should stay home from work, school, and social events to rest and to avoid spreading the virus to others, notes the CDC. For some, antiviral drugs can help lessen symptoms and shorten the length of the virus. While there is no cure for the flu, fever reducers such as Tylenol can help provide relief.
