The Body Hiv Aids
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
HIV is hard to get: Seconds. It does not survive outside of living bodily fluids. ...Read more
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 moreSee 1 more doctor answer

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
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
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
No, HIV causes AIDS: Human immunodeficiency virus (HIV) is the virus that causes progressive destruction of the immune system, which can lead to acquired immune 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. ...Read more
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
Does hiv window period depend upon the number of virus entered in body?
More virus=early hiv detection by pcr or 4th & less virus=late hiv detection?
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
Varies: Hiv disease symptoms varies from asymptomatic to symptomatic , depends on immune status and associated opportunistic infections. Early stage there is no symptoms , later have recurrent pneumonia , pcp ( pjp) pneumonia , recurrent hsv ulcers and so many others. ...Read moreSee 1 more doctor answer
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
Human immunodeficiency virus (HIV) is a lentivirus (a member of the retrovirus family) that causes acquired immunodeficiency syndrome (aids),  a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections ...Read more
