Período Prepatogénico del VIH/SIDA

Imagínate que una enfermedad es como una receta que necesita tres ingredientes principales para "cocinarse". En el caso del VIH/SIDA, estos tres elementos deben estar presentes antes de que la enfermedad se desarrolle.

El agente es el villano de la historia: el Virus de Inmunodeficiencia Humana (VIH). Este virus pertenece a la familia de los retrovirus y es el responsable directo de causar la enfermedad. Sin este virus, simplemente no hay VIH/SIDA.

El huésped somos nosotros, los seres humanos, pero algunos grupos tienen mayor riesgo. Entre estos están las personas que usan drogas intravenosas, quienes tienen múltiples parejas sexuales (tanto homosexuales como heterosexuales), trabajadoras sexuales, bebés de madres VIH positivas, y personas que reciben transfusiones de sangre u órganos.

Recuerda: El período prepatogénico es como el "antes" de la enfermedad - cuando todos los factores están presentes pero aún no hay síntomas visibles.

El medio ambiente incluye todo lo que nos rodea: nuestra población, los factores culturales de nuestra comunidad, si trabajamos en el sector salud, y dónde vivimos. Estos factores pueden aumentar o disminuir nuestro riesgo de exposición al virus.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
