Medicine and health 2In 1985 scientist discovered the human immunodeficiency virus better known as HIV, this wasthe virus responsible for AIDS, acquired immune deficiency syndrome. The virus is transmitted from oneperson to another through the exchange of bodily fluids such as blood, semen, breast milk and virginalsecretions. Sexual contact is the most common way in which this virus spreads among people but it canalso be transmitted by sharing needles when using drugs or during breast feeding young ones by amother. As the HIV virus spreads and damages the body?s immune system, the body becomessusceptible to illness and infection. The advanced state of HIV infection is called AIDS and this conditionis caused by significant loss of the white blood cells, this may result to body cancer or any otherinfection that may cause the immune system to be damaged. The disease has no cure and scientist havebeen trying out various methods to try cure the disease to no avail but some breakthrough have beenmade in the field of preventive and control of the disease. Being diagnosed with the disease can be anoverwhelming experience filled with worry about the future, concern for loved ones and fear of dyingA variety of drugs have been found to be useful in the control of the virus when used in givencombination this drugs are divided into different classes and each class blocks the virus in differentways. The best way to avoid a particular strain from developing resistance to the drug through mutationis by combining at least three drugs from different classes. These drugs include integrase inhibitors, thisdrug works by disabling integrase which is a protein that HIV uses to insert its genetic material into theCD4 cells. The other class is called fusion inhibitors; these drugs block HIV?s entry into the CD4 cells. Theprotein inhibitors otherwise known as the PI?s disable protease, this are the protein that the virus needsto make copies of its self. Nucleoside reverse transcriptase inhibitor s are another class of drugsdesigned to bond with the virus in its replication process, the trick is that this are faulty blocks henceinhibiting the cells replication.Experts atmidcoursecan help you with this and more.
