AIDS has now spread across the modern world and AIDS infections patients are able to live normal, productive lives because of great improvements in diagnosis and medical care. Previously in the 1980s and early 1990s there was nothing to be done against AIDS and many patients died because of the disease. Now that we know more about the disease, AIDS infection rate has declined and many people are getting treatment for their disease, which improves patients’ quality of life and prevents spreading of the deadly virus to other people around the world.
AIDS is caused by the Human Immunodeficiency Virus, or HIV. This virus exists in the blood and bodily fluids of patients who are infected and can be transferred to others in several ways. The usual mode of transmission is through sexual contact. During intercourse, fluids are exchanged and so is the virus. Any other infections can be transmitted as well and these will increase the probability of getting the virus that causes AIDS, HIV.
HIV infects a very specific type of cell, an immune cell that fights infection. This immune cell is called the CD4 cell, or helper T-cell. This cell floats around your body in your blood stream and exists to fight infection. If an infection is found, the CD4 cell becomes active and fights the infection. The CD4 cell is like the general, it directs other cells to do their jobs. That is why the HIV virus is so deadly, because it takes out the highest level of the immune system, preventing the body from mounting any type of attack.
If the HIV virus is not treated and left to grow, CD4 cells no longer function and that impairs the immune system. As a result, patient acquire several different types of diseases. Aids infections symptoms are a result of this impaired immune system. Normal bacteria that would not cause a normal person any harm can now be very deadly to an AIDS patient. Patients can be very sick with high fevers and pneumonia from an organism pneumocystis carninii. Another sign of an aids infection is kaposi’s sarcoma, which is a type of cancer that can develop in the skin. This cancer tends to cause dark patches that are slightly raised. There are few good treatments for kaposi’s sarcoma, the best is to treat the HIV infection.
Currently, there are many good treatments for HIV and AIDS infection. These include drugs that suppress the virus and cause it to become dormant. Drugs do not get rid of the virus; they just prevent it from growing and spreading throughout the body. These medicines need to be taken every day to be effective and are known to have many side effects. The best way to avoid AIDS is to prevent getting the HIV virus in the first place, by protecting yourself during sexual encounters and using infected needles. With proper treatment and prevention, the number of AIDS infections patients can be reduced world-wide and improve the health of the world by cutting out the virus.
