HIV or human immunodeficiency virus infection goes through several stages or stages before becoming fully AIDS symptoms.The stages of infection described in 1993 by the Centers for Disease Control and Prevention (CDC) are:
- Seroconversion illness
- Asymptomatic infection
- Persistent generalised lymphadenopathy (PGL)
- Symptomatic infection
It occurs 1 to 6 weeks after receiving the infection. About 20 to 60% of patients may have symptoms. Common symptoms are:
- fever with swollen lymph nodes
- feeling unwell
- body ache
- sore throat
- nerve damage or pain
Acute infection may be asymptomatic. The feeling is similar to a bout of flu.
After seroconversion, the virus level decreases and replication continues slowly. CD4 and CD8 lymphocyte levels are normal. There are no symptoms at this stage and it can last for years.
Persistent generalized lymphadenopathy (PGL)
In this stage, there is expanding of the lymph a hub more than 1 cm in measurement in something like two places an other than the pipe.Lymph nodes are swollen for three months or more and do not occur for any other reason.
This stage is accompanied by symptoms such as fever, night sweats, diarrhea and weight loss.In addition, there may be infections with organisms that usually cause mild or mild illness. These are include fungal infections such as oral candidiasis, vaginal or penile candida infections, facial hair leukoplakia, seborrheic dermatitis, tenia infections and viral infections such as herpes zoster, recurrent herpes simplex.
This combination of signs and symptoms is called AIDS-related complex (ARC) and is considered a precursor or precursor to AIDS.
Symptoms of life-threatening infections and abnormal tumors. Symptoms include:
- persistent tiredness
- night sweats
- weight loss
- persistent diarrhoea
- blurred vision
- white spots on the tongue or mouth (leukoplakia)
- dry cough
- shortness of breath
- fever of above 37C (100F) that lasts a number of weeks
- Swollen is glands that last for more than three months
Other infections like tuberculosis and pneumonia may occur at this stage. This stage is characterized by a CD4 T-cell count below 200 cells/mm3.
There is a little gathering of patients who is fostering AIDS gradually or is never. These are patients are is called non-progressive, and many have genetic differences that prevent the virus from significantly damaging their immune system.
Time taken for AIDS to develop
AIDS indicates advanced HIV disease and has no cure and is considered fatal. This is time from HIV infection to death is however depends on the management and with anti-HIV medications instituted on time and continued over long term is.The time period usually ranges from 6 months (rarely) to 15+ years. In the United Kingdom the average time is around 12 years.
