Introduction
Aids is a syndrome caused by a virus called HIV. HIV is found throughout all the tissues of the body but is transmitted through the body fluids of an infected person like semen, blood, vaginal fluids, and breast milk.
The disease alters the immune system, making people much more vulnerable to infection and diseases. This susceptibility worsens if the syndrome progresses.
Overview
AIDS is the syndrome which may or may not appear in the advanced stage of HIV infection. Hiv is a virus that immune cells called CD-4 cells, which are a subset of T cell. HIV is a virus.
Aids is a medical condition
Without any treatment, HIV can progress and eventually, it will develop into AIDS in the vast majority of causes. HIV infection can cause AIDS to develop. However, it is possible to contract HIV without developing AIDS.
Causes
HIV can be passed from one person to another through blood-to-blood and sexual contact. HIV is a retrovirus that infects the vital organs and cell of the human immune system.
The rate of virus progression varies widely between individuals and depends on many factors. The virus progresses in the absence of antiretroviral therapy (ART) a drug therapy that slows or prevents the virus from developing.
The factors include the age of the individual, the body’s ability to defend against HIV, access to healthcare, the presence of other infections, the individual’s genetic inheritance, resistance to certain strains of HIV and more.
Signs and symptoms
Many individuals develop an influenza-like illness or a mononucleosis-like illness 2-4 weeks post exposure while others have no significant symptoms.
The initial period following the contraction of HIV is called acute HIV, primary HIV or acute retroviral syndrome. Symptoms occur in 40-90% of the cases and most commonly include fever, large tender lymph nodes, and throat inflammation, a rash, headache, and/or sores of the mouth and genitals. The rash, which occurs in 20-50% of cases, presents itself on the trunk and is classically maculopapular.
Prevention of AIDS
Sexual contact
When one partner of a couple is infected, consistent protection use results in a rate of HIV infection for the uninfected person of
Below 1% per year. There is some evidence to suggest that female protection may provide an equivalent level of protection. Consistent protection use reduces the risk of
HIV transmission by approximately 80% over the long term.
Mother-to-child
This primarily involves the use of a combination of antivirals during pregnancy and after birth in the infant but also potentially includes bottle feeding rather than breastfeeding. Programs to prevent the transmission of HIV from mothers to children can reduce rates of transmission by 92-99%.
Vaccination
A single trial of the vaccine RV 144 published in 2009 found a partial reduction in the risk of transmission of roughly 30%, stimulating some hope in the research community of developing a truly effective vaccine. As of 2012, there is no effective vaccine for HIV or AIDS. Further trials of the RV 144 vaccine are on-going.
Conclusion
The small matter of proving that the virus caused the disease still remains, and it remains very good reasons. There is no valid evidence that the virus causes AIDS. There is an enormous weight of evidence to show that it does not.
