The Swedish Law for Communicable Disease Control The Law was rewritten July 2004 and a summary follows:
The law states, the rights of an infected person or a person believed to be infected with Chlamydia (by himself/herself or treating physician). They have the right to have a clinical examination, testing, and treatment for free. They also have the right to receive appropriate information about the disease.
The law further states the requirements of an infected person or a person believed (by himself/herself or treating physician) to be infected with Chlamydia. Requirements are to allow a clinical examination and testing. The person is also further required to follow certain rules, such as no sexual intercourse before the treatment is completed and to give information (name, or address, or phone number) about the partners who are believed to have transmitted or acquired the infection. The required retrospective time span for partner tracing varies between 6 months and over a year depending on regional differences in medical routines.
The infected person or a person believed (by himself/herself or treating physician) to be infected with Chlamydia is personally required to take necessary precautions to not spread the infection and also inform his or her sexual partner about the infection.
