Number of reported cases At least 5 How do we calculate the number of cases


Morelos criminalises both perceived ‘exposure’ and the actual transmission of disease through its injury provisions.

Article 136 of the Penal Code criminalises anyone who knows they are living with a serious disease and who puts themselves at “risk of contagion to another” by any means with a penalty of six months to one year’s imprisonment and treatment for up to one year. The penalty is doubled in the case of incurable diseases.

This provision explicitly clarifies that this law not only penalises intentional, reckless, thoughtless or negligent behaviour that has a sexual character, but any conduct that puts another at risk of contracting any serious disease.

In June 2024, it was reported that HIV activist were seeking to have Article 136 repealed because of its impact on people living with HIV. Positivos Morelos stated that at least five people living with HIV were imprisoned under this provision due to alleged HIV transmission. An successful attempt to repeal the law was initiated in 2022.

Article 121, which criminalises the infliction of injuries, states that anyone who causes an incurable illness is liable to three to eight years’ imprisonment and three thousand days’ fine.
