Hiv (Definition)

Hiv infection is caused by a retrovirus....This retrovirus binds to CD4 cells (for the most part). You may detect the virus by several different methods. An elisa test (enzyme linked immunosorbent assay). You may also detect it by doing a test referred to as a western blot (a gel protein electrophoresis). Thirdly by pcr (polymerase chain reaction) which ...Read more

7 doctors agreed:
Are HIV and aids the same?

Subtle difference: There is a subtle difference. Human immunodeficiency virus (HIV) is the virus that causes progressive destruction of the immune system, which can lead to acquired immund deficiency syndrome (aids). As the immune system declines, a person can get one of 20+ opportunistic infections associated with aids. A person can also have aids if their cd4 or t-cell count (marker of immune function) is <200. ...Read more

Is there any statistics for HIV1/HIV2 ratio in all HIV world?i.e %80 of HIV infected people carry HIV1?

Is there any statistics for HIV1/HIV2 ratio in all HIV world?i.e %80 of HIV infected people carry HIV1?

HIV: HIV 1 is more prevalent in the US and Europe and HIV 2 are more prevalent in Africa. But there are no statistics because a big portion of the population does not even know their HIV status. HIV is now increasing in the 16 years old to 25 years old, despite education most people are having sex without protection and also there is an increase in multiple sex partners. Misconception medications cure. ...Read more

How is the HIV virus passed into the body tissues?

How is the HIV virus passed into the body tissues?

Various ways: The virus has reservoir cells where it remains inactive in tissues. These are macrophages and in the nervous system some neurons. It lives within lymphocytes (cd4 cells), and other cells which possess a receptor site to which it can attach and enter the cells. These cells then carry it into tissues. When the virus first enters the body it does so onto receptive surfaces. ...Read more

Benefit of haart in HIV aids ?

Benefit of haart in HIV aids ?

Absolutely: Highly active anti-retroviral therapy usually consists of a combination of several different classes of agents which are inhibitory to hiv. The combinations attack the virus from multiple different biological pathways, make resistance development more difficult, allow restoration of large parts of the damaged immune system, make transmission to others less likely and extends life of patients. ...Read more

How do the RNA molecules of HIV and West Nile virus (WNV) differ in number and function?

How do the RNA molecules of HIV and West Nile virus (WNV) differ in number and function?

Which ones?: There are dozens of variants of HIV and West Nile virus. I believe the genomes for all of them have been sequenced and the sequences published. There are many open-source sequence-alignment software packages available for download. Many run better under Linux than Windows. Do you have a preference? ...Read more

How much is the lifespan of the HIV virus outside the human body?

Very brief: This virus is very susceptible to physical elements, particularly drying, heat, cold, etc. It may survive slightly longer when present in warm wet material like semen or vaginal secretions, and particularly in blood. As soon as these dry the organism will die quickly. ...Read more

What is sensitivity and spesifity of the HIV / aids PCR test?

What is sensitivity and spesifity of the HIV / aids PCR test?

High: Since the test is looking for the virus itself it is very specific. There should be no false positives of titers that are significantly above the minimum of detection (of course some human error is always possible). Similarly, since it amplifies any detected viral RNA a million-fold, it is also very sensitive. ...Read more

Can hepatitis virus infection interfere the progression of HIV disease?

Can hepatitis virus infection interfere the progression of HIV disease?

Yes: Co infection with hepatitis b or hepatitis c ( that is having HIV and either of the above) is documented to generally result in further progression of both diseases. Therefore, patients with either illnesses must be screened to rule out co infection... Treatment is encouraged for both viral illnesses. New treatments are available for hepatitis c. ...Read more
