Hi everyone!
So after preparing for numerous activities that happened on world aids day 2011, i realised that not many people truly understands the illness and often tend to avoid persons living with it. so for this post i will be posting some facts about HIV and AIDS.

What is HIV?
HIV stands for ‘human immunodeficiency virus’. HIV is a virus (of the type called
retrovirus) that infects cells of the human immune system (mainly CD4 positive T cells
and macrophages—key components of the cellular immune system), and destroys or
impairs their function. Infection with this virus results in the progressive deterioration of
the immune system, leading to ‘immune deficiency’.
The immune system is considered deficient when it can no longer fulfill its role of fighting
off infections and diseases. Immunodeficient people are more susceptible to a wide
range of infections, most of which are rare among people without immune deficiency.
Infections associated with severe immunodeficiency are known as ‘opportunistic
infections’, because they take advantage of a weakened immune system.

What is AIDS?
AIDS stands for ‘acquired immunodeficiency syndrome’ and is a surveillance definition
based on signs, symptoms, infections, and cancers associated with the deficiency of the
immune system that stems from infection with HIV.

What are the symptoms of HIV?
Most people infected with HIV do not know that they have become infected, because
they do not feel ill immediately after infection. However, some people at the time of
seroconversion develop “Acute retroviral syndrome” which is a glandular fever-like
illness with fever, rash, joint pains and enlarged lymph nodes.
Seroconversion refers to the development of antibodies to HIV and usually takes place
between 1 and 6 weeks after HIV infection has happened.
Whether or not HIV infection causes initial symptoms, an HIV-infected person is highly
infectious during this initial period and can transmit the virus to another person. The only
way to determine whether HIV is present in a person’s body is by testing for HIV
antibodies or for HIV itself.

After HIV has caused progressive deterioration of the immune system, increased
susceptibility to infections may lead to symptoms.

HIV is staged on the basis of certain signs, symptoms, infections, and cancers grouped
by the World Health Organization (WHO).

Interim WHO clinical staging of HIV/AIDS and HIV/AIDS case definitions for surveillance

– Primary HIV infection – may be asymptomatic or experienced as Acute retroviral
-Clinical stage 1 – asymptomatic or generalized swelling of the lymph nodes
-Clinical stage 2 – includes minor weight loss, minor mucocutaneous
manifestations, and recurrent upper respiratory tract infections
-Clinical stage 3 – includes unexplained chronic diarrhoea, unexplained persistent
fever, oral candidiasis or leukoplakia, severe bacterial infections, pulmonary
tuberculosis, and acute necrotizing inflammation in the mouth.
Some persons with clinical stage 3 have AIDS.
– Clinical stage 4 – includes 22 opportunistic infections or cancers related to HIV.
All persons with clinical stage 4 have AIDS.
Most of these conditions are opportunistic infections that can be treated easily in healthy

How quickly do people infected with HIV develop AIDS?
The length of time can vary widely between individuals. The majority of people infected
with HIV, if not treated, develop signs of HIV-related illness within 5-10 years, but the
time between infection with HIV and being diagnosed with AIDS can be 10–15 years,
sometimes longer. Antiretroviral therapy can slow down disease progression to AIDS by
decreasing the infected person’s viral load.
WHO recommends initiation of antiretroviral therapy for all HIV-infected adolescents and
adults who are at clinical stage 4 or have a CD4 positive T cell count below 200 per
mm3, and for some persons who are at clinical stage 3.

So there you have it, HIV and AIDS isnt a death wish so show these persons living with HIV and AIDS love and support.
