The Penal Code of Sonora criminalises perceived ‘exposure’ as well as actual transmission of diseases. The law also penalises parents and guardians who allow their children who are living with a disease to be breastfed.

Article 249 states that anyone who, knowing they are living with a venereal or serious and transmissible disease, has sexual relations, breastfeeds, or in any other direct way puts another “at risk of contagion” is liable to a fine of forty to three hundred units and mandatory confinement in a suitable establishment until they have recovered from the disease. In the case of incurable diseases, the penalty is six months to five years’ imprisonment and a fine of ten to two thousand units.

In the case of partners individual complaint is required.

Article 250 penalises parents or guardians who know that their children are suffering from an illness outlined in Article 249 and who allow them to be breastfed by a wet nurse. The penalty for this offence is a fine of twenty to two hundred units, except in the case of incurable diseases in which the penalty is six months to five years’ imprisonment and a fine of ten to two thousand units.

Article 251 states that where transmission takes place, the accused will be liable for punishment under the injury and homicide provisions.

Under Article 259, injury and homicide are considered qualified and subject to higher penalties when premeditated, which explicitly includes intentional contagion of a venereal or other serious and transmissible disease.

The 2017 report by the Mexican Network Against the Criminalisation of HIV suggested that there had been nine HIV criminal cases in Sonora.
