.-With the aim of reducing the incidence of new cases due to the Human Immunodeficiency Virus (HIV) and increasing the timely detection of this and other sexually transmitted diseases, since 2020, in the second-level hospitals of the Mexican Institute of Social Security (IMSS) HIV Pre-Exposure Prophylaxis (PrEP) is prescribed as an effective prevention method.

This prevention resource, which has been shown to reduce the risk of acquiring HIV from 44 to 67%, works with the daily taking of two drugs combined in a single tablet, which blocks the reproduction of the virus in the blood, however, It is necessary to accompany this method with regular condom use to prevent other sexually transmitted infections such as syphilis, gonorrhea or chlamydia.

PrEP is indicated for people at high risk of acquiring the Human Immunodeficiency Virus and since its prescription to date, around 400 applications have been received to join this prevention initiative, of which 258 people are already linked to this mechanism .

Clinical studies have shown that PrEP is highly safe to prevent this virus and the possibility of adverse effects is very low; However, the only contraindication for use is that the person has deterioration in renal function or allergy to the components of the treatment, therefore, prior to this treatment, it is necessary to carry out a comprehensive evaluation to rule out HIV, hepatitis B or C, in If these conditions are detected, prompt treatment will be provided.

To access HIV Pre-Exposure Prophylaxis, it is necessary to register by mail at [email protected], where in a period of no more than 10 days the user is contacted by the IMSS team under the framework of confidentiality and the appointment is managed directly in the medical unit where internists and infectious disease specialists will evaluate the person and determine if it is candidate or not for this prophylaxis.

Once the patient starts this therapy, it is accompanied by counseling as a primary part of the treatment, as well as their adherence to it, and in this sense, close surveillance is maintained in order to verify the efficacy of PrEP. HIV tests are done every four to six months, and hepatitis B and C tests are done annually, as well as kidney function tests.

With these actions, the IMSS realizes its commitment to promoting safe sexual practices, in this sense, this places Social Security as the first institution to approach and treat these people under this prevention initiative.
