Hemophilia is passed down from mother to son. It is extremely
rare for a woman to have hemophilia. It is necessary, though, for
a woman to be a carrier of the disorder for her son to acquire this
disorder. Females have two X chromosomes whereas males only
have one. When a boy is born, he takes one X chromosome from
his mother and one Y chromosome from his father. Therefore, he
can only get hemophilia through his mother.
Example One:
Mother(Carrier)+Father(Non-Affected)=50% chance of their son
acquiring the disorder and 50% chance of their daughter being a
carrier.
Example Two:
Mother(Non-Affected)+Father(Hemophiliac)=All sons will be
non-affected and all daughters will be carriers.
People with hemophilia are born with it. Hemophilia is a hereditary disease - in other words, it "runs in families" (is inherited).
There is another type of hemophilia called acquired hemophilia. Acquired hemophilia results from the development of autoantibodies (mostly of the IgG1 and IgG4 subclasses) directed against clotting factors. Acquired hemophilia can be brought on by reactions to medications such as penicillin, sulfonamides, phenytoin, methyldopa, chloramphenicol, interferon alpha, and others.
Currently, there is no means of prevention for genetic hemophilia. That is to say, other than not having children at all. The best measure one can have is awareness. Knowing what conditions run in your family and can be genetically passed on is always a good idea. Even then, the spontaneous mutations make genetic hemophilia impossible to prevent in its entirety.
As for acquired hemophilia, there are ways to lower the chance of getting it. First, realized that acquired hemophilia is already rare so reducing the chance of acquiring it is probably not the priority of the masses. Since acquired hemophilia can result from extensive liver damage and certain medications, living a healthy lifestyle can actually help prevent it.
Hemophilia is most often passed down from mother to son. It is possible for hemophilia to be the result of a spontaneous mutation (approximately 1/3 of the known cases are). Hemophilia is due to a mutation on the X chromosome. Females have two X chromosomes whereas males only have one. When a boy is born, he takes one X chromosome from his mother and one Y chromosome from his father. Therefore, he
can inherit hemophilia only from his mother.
Example One:
Mother(Carrier)+Father(Non-Affected)=50% chance of their son
acquiring the disorder and 50% chance of their daughter being a
carrier.
Example Two:
Mother(Non-Affected)+Father(Hemophiliac)=All sons will be
non-affected and all daughters will be carriers.

hemophilia B is also known as Christmas disease because Stephen Christmas was the first patient with the disease, and hemophilia A is just known as classic hemophilia.
50 million ppl have hemophilia
Her father has to have hemophilia as well, and the mother is a carrier or also has hemophilia. So if we pretend that the hemophilia gene is "x", you need to have "xx" to have hemophilia. The father must have the genotype "Yx" and the mother has the have "Xx" or "xx".

You have to be born with hemophilia, it is not something people can "catch".
You can be born with it.
Approximately 1 in 5000 males born have hemophilia. Approximately 1 in 10,000 children have hemophilia.
Hemophilia is not contagious by any means, however it can be passed from parent to offspring in the way of genetics.
It is possible but extremely rare.

There is no chance that the child will have hemophilia even if the spouse has hemophilia. Any girls the couple has will be carriers if the spouse has hemophilia.
