Use latex condoms every time you have sex. Condoms, when used correctly, may prevent pregnancy and diseases like hepatitis B, syphilis, and other sexually transmitted diseases. Stay in a relationship with one person who you know is not infected with hepatitis B and who does not inject drugs. A blood test is the only way to know for certain that a person is not infected with hepatitis B. Do not use illegal drugs. If you cannot stop using drugs, do not share needles or syringes with anyone.
Rubella is a virus that spreads from one infected person to another through respiratory secretions.
This means that a person with rubella who coughs or sneezes can spread the disease to another person. Another name for rubella is German measles. Rubella is usually a mild disease. Persons infected with rubella may have a slight fever and a rash that starts on their neck, behind their ears, or on their faces. They may also have swollen glands and feel achy.
