What Is Influenza A?
Pretty much everybody will have had the flu at least once in their lives. Many people are even likely to have it at least once every year. The symptoms of the flu tend to be more uncomfortable than those of the common cold, but they should still not cause serious problems for us.
Most cases of the flu will clear up with help from our immune system, and the patient will often only need a few days of work or school. It can be serious in a small percentage of cases, however, so it should not be treated with complacency.
