Hemophilia is a disease that prevents the blood from clotting properly. It is hereditary and occurs in one in 10,000 births. It affects males, with women being asymptomatic carriers. There are three types: A, B and C and they have different degrees of severity. The most severe cases manifest as abnormal bleeding, which can be spontaneous. For example, bleeding into the joints, skin, muscles and nosebleeds, etc. from childhood. Diagnosis is clinical and based on the family history, and is confirmed with blood tests. Genetic tests should be performed on the family. It is important to prevent bleeding. Treatment consists of replacing the missing clotting factor.
