Why is a person with an HIV infection unable to get rid of this infection the way a person can get rid of...?

A person who becomes infected with the HIV virus is unable to get rid of it. With highly effective modern medical treatment, a person may survive a long time with an HIV infection, but an untreated HIV-infected individual is very likely to develop AIDS and die. Why is a person with an HIV infection unable to get rid of this infection the way a person can get rid of an infection the way a person can get rid of an infection with a cold or flu virus?

Ok, firstly for a virus to infect someone, it must enter a cell type. cold viruses enter your nasal, oral or respiratory epithelium. (top layer) this is where the interaction of the virus and host (you) causes inflammation and your body's response is the symptoms of a cold.

HIV enters a specific cell called a T helper cell (also marked, and know as CD4) this cell is crucial to your immune system. HIV is called a retrovirus as basically it converts it Genome into a length of DNA that incorporates it's self into the human T-cells DNA. So if, in theory you removed all the HIV virus from your body, the virus can come back, as you immune system would make it!

sound strange but one of the reasons its such a nast bug. While in the T cell it multiplies and spreads to other cells, then destroyes the T cells it's in.
HIV can be monitored by two methods: virus count, and T cell count. Ideally you want virus count of 0 and a high T cell count.

HIV can be combated using drugs, including a group called "reverse transriptase inhibitors" these slow down the rate that the HIV virus can multiply andincorpotate it'sself into you body. So if have HIV, get a cocktail of antiHIV drugs, you can life almost as long as you would without the virus.

The main problem with HIV is as it attacks your immune system, it makes you vulnerable to all sorts of other diseases.

The human body isn't able to get rid of a lot of viruses. Even though you will get some immune response, the response isn't always able to completely clear the virus. It turns out that some viruses are simply very good at evading your immune system.

For example, if you have ever had chicken pox (varicella zoster virus), you still have some of the virus living in some of your nerve cells. Your immune system can keep the virus in check, but it isn't able to completely kill it either. Sometimes this virus becomes active again, which is what causes shingles.

well firstly HIV is a virus and most medicines n drugs are unaffective on viruses plus the HIV virus changes its RNA n DNA structure very often

HIV is a very special type of virus because it directly attachk your defense mechanism. Imagine, if your country defense mechanism is directly being attack by its enemies, it is difficult to get rid of the resistance.

HIV virus attack the specific cell type in your immune system, called CD4 cells. CD4 cells is a type of T cells and its function is not aimed for direct attack but to communicate with other cell type to make "weapons", the effective antibodies. However, this chain of commands lost with the infection.

Even when the body make antibodies, it is not effective against the virus. therefore, the body since cant not fight the virus and your defense mechanism is damaged. HIV will not kill you, but lost of defense, you are fully exposed and other infectious agents can kill the patient.
