Human Immunodeficiency Virus or HIV, is the causal agent behind the most dreaded disease in human history, AIDS. AIDS has taken the maximum number of lives in the recent past. When compared to other epidemics, it can be seen that the toll taken on human life by AIDS has reached about 25 million. The fact that no permanent cure for AIDS could yet been devised has made it even more dangerous. AIDS occurs, when an individual gets infected by the retrovirus, HIV. HIV or Human Immunodeficiency Virus attacks the immune system of human beings, thus making them vulnerable to the most insignificant of diseases. In the recent past several HIV/AIDS Drugs have been invented, which helps a person to live a healthy life even after being infected by the HIV. But at times, the HIV can change itself or mutate. This makes the virus escape the effects of the anti-retroviral drugs. This condition is known as HIV drugs resistance. It is very important to stick to regular medication, if an infected individual wants to lead a healthy life. This sticking to a strict regimen is called adherence to a drug. HIV Drug Resistance and Adherence, is a major topic of research and debate among medical practitioners.

The HIV infects a CD4 cell, from which it starts replicating. The replicated viruses goes on to infect the other cells. During the process of replication, it is common for the HIV to mutate itself. This helps the viruses to replicate even in the presence of anti-retroviral drugs. Thus developing HIV Drug Resistance. This is why it is very important to block the process of replication by the virus. Once the process of replication is stopped, the virus can not mutate any more. This in turn means that the virus can not become drug resistant. Thus adherence to drugs is probably the most important thing to do, while undergoing treatment for HIV. The theory of HIV Drug Resistance and Adherence has led to the development of several anti-retroviral drugs which are helping infected people live a healthy life.
