How is AIDS


How is AIDS


There are medicines that can treat symptoms but can not cure AIDS. At present there is no cure for this disease. But doctors and scientists working to discover the world. Similarly, there is medication that helps people living with HIV to have a longer and healthier life. It has new antiviral drugs, and combinations thereof are very useful in combating the HIV virus. They work by preventing it from multiplying and destroys T cells There are also new drugs used to prevent or treat infections that often develop when a person has AIDS. What makes it difficult the treatment of this disease is that HIV can mutate, meaning that transforms. When this happens, some antiviral drugs are unable to act against the virus because it changes so that the drug can not recognize and attack. However, continually develop new drugs to combat HIV and sometimes their different combinations work mejor.Aunque physicians and scientists are working on a vaccine to prevent AIDS, it is worth clarifying that development and testing of a vaccine will take years.

Prevention


Prevention


Already there have been forms of contagion, now see how to prevent - through sex: Whenever you have penetrative sex (anal, vaginal or oral) and is not known if any person is HIV seropositive or not, is should properly use a condom as a preventive method. Today, every day, 14,000 people infected with HIV worldwide, and nearly 90% of new infections are sexually transmitted via blood .-: Sharing injection equipment carries a high risk of infection. Today this practice is limited almost exclusively to people who inject illegal drugs. Prevention focuses on the use of injection equipment (syringe and needle) and use one single container, or the filter system with each new use through perinatal .-: If an HIV + woman decides to get pregnant need to take into account going to be a risk pregnancy. As must conduct a rigorous medical follow the same, knowing that there are treatments that reduce the risk of transmitting HIV to your baby.

Información y prevención


Information and prevention


HIV is the virus that, according to most experts, get AIDS. Although there is no specific vaccine to cure this disease, if there are several drugs which combine to decrease the symptoms. How is it spread and how to prevent it, is information that nobody can ignore. Forms of contagion HIV can be transmitted from an infected person to another through the following fluids: blood (including menstrual blood), semen, vaginal secretions, from mother to baby through breast milk. Blood contains the highest concentration of virus, followed by semen and fluids can be carried by vaginales.También: pre-ejaculatory fluid (pre-semen). Although not seen that this fluid transmit HIV, it can contain small amounts of sperm and white blood cells do. As you know, a secure transmission route is when the virus enters the bloodstream. This can happen in three main ways: unprotected sex, by direct contact with blood (including sharing needles for drugs that are injected, or blood transfusions), from mother to baby (before or during birth, or through the breastmilk.) HIV can enter the body through open wounds or mucous membranes directly infect. Transmission can occur in the anus or rectum, vagina and penis in the mouth (much less risky) and eyes. These body parts need protection when in contact with infected fluids. HIV can not pass through skin that is healthy, without recientes.Así cut as there are some things that infect the VHI, there are others who do not, such as feces, saliva, sweat, tears, urine, insects (this virus is not transmitted by mosquitoes, flies, fleas, bees or other insects similar). If an insect sucks blood from someone infected with HIV, the virus dies in the stomach bug (while digesting the blood). Nor is spread by sharing plates, utensils or food. In cases of blood donation, if the needles are sterilized to prevent possible infection of blood donors

CHARACTERISTIC


Features of AIDS AIDS


(Acquired Immune Deficiency Syndrome) is a disease caused by chronic and prolonged damage to the immune system (defense system) to the human body caused by a virus known as HIV (in English: Human Immunodeficiency Virus). AIDS is a condition called Syndrome, and which, on the gradual destruction of our immune system, microorganisms usually inhabit our body without causing harm or cause minimal damage, they become highly dangerous because they spread and assault our bodies to be the answer diminished our immune system, thus causing a variety of diseases (diarrhea boxes, atypical pneumonia, cancer, tuberculosis, etc.). Our immune system begins to be damaged due to virus replication of HIV, and that, when divided into one of the key cells of our immune system (among others) called T lymphocytes emigrating from the cell causes its death. On the other hand as the virus divides and destroys T cells, the amount of virus in the blood begins to increase and be available to continue and further destroying infected cells. That is why it is called Immune deficiency because a deficiency in the action of the defense system, mainly by the destruction of CD4 + T cells. The word? Acquired? comes from the fact that there are diseases in humans, not very frequent, but for various factors, some of them caused by errors in genes (where information is stored for transmission to the offspring), produce low response to situations attacks by microorganisms by our defense system similar to those produced by the HIV virus, but in this case are not acquired but are due to errors the agency itself.

DEFINITION


DEFINITION


Acquired immunodeficiency syndrome, most referred to by its acronym AIDS or AIDS is a disease that affects humans infected by HIV. They say a person has AIDS when his body due to the immunodeficiency caused by HIV, is not capable of providing an adequate immune response against infections that afflict humans. Note the difference between being infected by HIV and suffering from AIDS. A person infected with HIV is HIV positive and goes on to develop a cadre of AIDS when their level of CD4 T cells that attack the virus, falls below 200 cells per milliliter of blood. HIV is transmitted through the following body fluids: blood, semen, vaginal secretions and breast milk

Cómo se trata el SIDA




Cómo se trata el SIDA





Existen medicamentos que pueden tratar los síntomas pero no pueden curar el SIDA. En la actualidad no existe una cura para esta enfermedad. Pero médicos y científicos del mundo trabajan para descubrirla. De igual manera, existe medicación que ayuda a las personas infectadas por VIH a tener una vida más larga y saludable. Se dispone de nuevos fármacos antivirales, y las combinaciones de éstos son muy útiles a la hora de combatir el virus del VIH. Actúan evitando que éste se multiplique y destruya las células T. También existen nuevos medicamentos que se utilizan para prevenir o tratar las infecciones que a menudo se desarrollan cuando una persona tiene SIDA. Lo que hace difícil el tratamiento de esta enfermedad es que el VIH puede mutar; esto significa que se transforma. Cuando esto sucede, algunos fármacos antivirales son incapaces de actuar contra el virus, porque éste cambia de modo que el fármaco no lo pueda reconocer y atacar. Sin embargo, continuamente se desarrollan nuevos medicamentos para combatir el VIH y a veces sus distintas combinaciones funcionan mejor.Aunque médicos y científicos estén trabajando en una vacuna para prevenir el SIDA, vale aclarar que el desarrollo y ensayo de una vacuna tardará años.

Prevención


Prevención


Ya se han visto las formas de contagio, ahora veamos cómo prevenirlas:- Por vía sexual: Siempre que se tengan relaciones sexuales con penetración (anal, vaginal u oral) y se desconozca si alguna de las personas es o no seropositiva al VIH, se debe utilizar de forma adecuada el preservativo como método preventivo. Hoy, cada día, se contagian de VIH 14.000 personas en el mundo, y casi el 90 % de los contagios son por transmisión sexual.- Por vía sanguínea: Compartir material de inyección conlleva un riesgo muy alto de contagio. En la actualidad esta práctica queda circunscrita casi exclusivamente a las personas que se inyectan drogas ilegales. La prevención se centra en la utilización de material de inyección (jeringa y aguja) de un solo uso y recipiente individual, o la esterilización correcta en cada nueva utilización.- Por vía perinatal: Si una mujer VIH+ decide quedar embarazada tendrá que tener en cuenta que va a ser un embarazo de riesgo. Por lo que deberá efectuar un riguroso seguimiento médico del mismo, sabiendo además que hay tratamientos que disminuyen el riesgo de transmisión del VIH de su bebé.
