V: Virus, es un organismo muy pequeño, que no tiene la capacidad de reproducirse por sí solo. Este virus en particular se reproduce solamente al invadir células humanas, no afecta a los animales. El VIH es un virus frágil que no puede sobrevivir fuera del cuerpo.

I: Inmunodeficiencia, porque el efecto de este virus es crear una deficiencia al correcto funcionamiento del sistema inmunológico del cuerpo. Infecta y destruye las células inmunológicas, llamadas T4, para crecer y reproducirse. Provoca que el organismo quede indefenso, esta situación es aprovechada por diversas infecciones y cánceres para atacar al organismo y causar su muerte. A estas enfermedades se las denomina "oportunistas", pues aprovechan la debilidad del sistema inmune para atacar. Con el tiempo el virus debilita las defensas de la persona contra la enfermedad, dejándolo vulnerable a muchas infecciones y formas de cáncer que no se desarrollarían en personas saludables.

H: Humana, porque el virus solo puede ser contraído por seres humanos. En el reino animal existen virus con características similares en simios y felinos. Se cree que proviene de un tipo específico de mono africano.

El VIH pertenece a los retrovirus. El VIH sólo puede replicarse en el interior de las células, ordenando la reproducción a la maquinaria de la célula. Pertenece a la familia de los retrovirus, lo cual significa que es capaz de invertir la dirección de la información que normalmente fluye del ADN al ARN, pero que en este caso lo hace en sentido inverso gracias a la transcriptasa inversa, introduciendo de esta manera su código genético y por medio de la integrasa lo "integra" al código de la célula CD4 infectada, lo que permite que ésta en lugar de multiplicarse, lo que hace es producir nuevos virus, llamados viriones.

El VIH es un lentivirus. El VIH pertenece a un subgrupo de retrovirus denominados lentivirus, o virus "lentos". El curso de la infección por estos virus se caracteriza por un período prolongado entre la infección inicial y la aparición de síntomas graves. Se sabe que desde el momento de la infección inicial se reproduce constantemente, principalmente en el sistema linfático.

La fiebre tifoidea es una infección bacteriana que afecta el intestino y ocasionalmente el torrente sanguíneo. El germen que causa la tifoidea es una variedad de la salmonella, llamada Salmonella typhi. La enfermedad puede ser contraída por cualquier persona, pero el mayor riesgo lo corren las personas que visitan países donde la enfermedad es común.

English Translation:

V: Virus, is a very small organism, which does not have the capacity to reproduce itself. This particular virus reproduces only by invading human cells, it does not affect animals. HIV is a fragile virus that cannot survive outside the body.

I: Immunodeficiency, because the effect of this virus is to create a deficiency in the proper functioning of the body's immune system. It infects and destroys immune cells, called T4, to grow and reproduce. It causes the organism to be defenseless, this situation is used by various infections and cancers to attack the organism and cause its death. These diseases are called "opportunists," because they take advantage of the weakness of the immune system to attack. Over time the virus weakens the person's defenses against the disease, leaving him vulnerable to many infections and forms of cancer that would not develop in healthy people.

H: Human, because the virus can only be contracted by humans. In the animal kingdom there are viruses with similar characteristics in apes and felines. It is believed to come from a specific type of African monkey.

HIV belongs to retroviruses. HIV can only replicate inside the cells, ordering the reproduction to the machinery of the cell. It belongs to the family of retroviruses, which means that it is able to reverse the direction of the information that normally flows from DNA to RNA, but in this case it does it in the opposite direction thanks to the reverse transcriptase, thus introducing its genetic code and through the integrase it "integrates" the code of the infected CD4 cell, which allows it instead of multiplying, what it does is produce new viruses, called virions.

HIV is a lentivirus. HIV belongs to a subset of retroviruses called lentiviruses, or "slow" viruses. The course of infection by these viruses is characterized by a prolonged period between the initial infection and the appearance of severe symptoms. It is known that from the moment of the initial infection it reproduces constantly, mainly in the lymphatic system.

Typhoid fever is a bacterial infection that affects the intestine and occasionally the bloodstream. The germ that causes typhoid is a variety of salmonella, called Salmonella typhi. The disease can be contracted by anyone, but the greatest risk is that of people who visit countries where the disease is common.
