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.

1. Type A Influenza

Influenza, more commonly known as the flu, is one of the most common illnesses that people are likely to have. There are also 4 different types of influenza virus, known as A, B, C and D. Type A influenza is the most common of the influenza viruses, and it is also often the most severe.

Although the type A influenza virus is the most severe, it is still not usually a danger and the vast majority of people with the disease will have only mild symptoms. It can be a lot more dangerous in vulnerable people, however, and those that are at risk should be extra careful to keep themselves safe from the disease.
