Querétaro penalises both perceived ‘exposure’ and actual transmission of disease.

Article 127 criminalises anyone who causes “damage to another’s health” which results in an incurable illness, with a penalty of two to five years’ imprisonment.

Article 127bis-1 criminalises anyone who knows they are living with a serious illness which they don’t disclose, and who puts another in “danger of contagion” through sexual or other means. The penalties are those outlined under Article 127.

In the case of partners individual complaint is required.
