Tamaulipas is one of two states that makes explicit reference to HIV/AIDS in its Penal Code.
Article 203 states that anyone who knows they suffer from a venereal disease or AIDS (sic), and who puts another in “danger of contagion” through sexual relations is liable to imprisonment for six months to three years and a fine of fifteen to fifty days.
In the case of partners and spouses, an individual complaint is required.
Under Article 341, injuries are presumed to have been inflicted with premeditation where they are caused by venereal contagion, which may result in enhanced sentencing for these offences.
