What is HIV/AIDS

HIV or Human Immunodeficiency Virus is a sexually transmitted or blood transmitted virus which is the instigator for AIDS. The virus works by infecting cells in the human immune system such as the T-cells. The HIV infection is considered a global pandemic by the WHO (world health organization). HIV infects about 0.6% of the worlds total populace, many of these infections occur in africa alone.

Those with the HIV infection who are left untreated eventually develop AIDS. AIDS or Acquired Immunodeficiency Syndrome is a disease of the immune system in humans. The disease kills off immune system cells, weakening it and leaving it susceptible to many other illnesses. Its grants access  to many different types of viral and bacterial infections and also harmful conditions such as tumours which would not appear in a person with a healthy immune system. As the body no longer has a way to fight such diseases even viruses like the common cold may become extremely serious. The WHO estimates that as much as 34 million people are living  AIDS right now with 2.7 million infections annually. Of these infections there will be 2 million deaths annually with 76% in africa alone.

HIV is not only a transmitted disease but also an inherited one as one generation can receive the infection from the last. This makes the disease even more deadly as many of those infected do not have access to AIDS medication and in children the disease may not even be noticeable until its too late. This trait of the virus gives it the potential to wipe out entire generations and decimate populations.

There is no known cure for HIV/AIDS although virologists are working everyday to find a cost effective remedy. So far technology has only allowed us to slow down the spread o the disease and increase the amount of time that infected persons have to live with the disease.
