Is HIV eradicated?
In particular, the complete elimination, or "eradication," of HIV from an infected individual has never been achieved, and perhaps may never be achieved because HIV has the capacity to remain dormant in certain cells and also to infect difficult-to-reach cells in the central nervous system and other parts of the body.
What is combination therapy for HIV?
The introduction of antiviral medications used in combination is among the most important advances in the history of HIV/AIDS treatment. By using more than one drug at a time, combination therapy is able to "pin down" HIV from more than one angle, so that even if one drug fails, another can continue to suppress viral replication. But this advance was a long time in the making, following a historical course from "no therapy" to "monotherapy" and now to "combination therapy." This book excerpt provides a historical overview of advances in the monitoring of treatment progress and the emergence of combination therapy.

What is ZDV used for?

What is the purpose of Zidovudine?
Food and Drug Administration (FDA) approved the first antiviral drug zidovudine (ZDV; AZT) for use in preventing HIV replication by inhibiting the activity of the reverse transcriptase enzyme. AZT is part of a class of drugs formally known as nucleoside analog reverse transcriptase inhibitors. After 1991, several other nucleoside analogs were added to the anti-HIV arsenal, as were a new class of anti-HIV drugs called the non-nucleoside analog reverse transcriptase inhibitors which work in similar ways to the nucleoside analogs but which are more quickly activated once inside the bloodstream. Next to be developed were the class of antiviral drugs known as protease inhibitors, which were distinctly different from the reverse transcriptase inhibitors in that they do not seek to prevent infection of a host cell, but rather to prevent an already infected cell from producing more copies of HIV.
How does drug resistance affect treatment?
Drug resistance can seriously complicate treatment by rendering drugs less effective or even completely ineffective. Further, once an organism has developed resistance to one drug, it can also become resistant to other drugs in the same class (cross-resistance) or to a number of different drugs (multidrug resistance).
Why did HIV emerge?

What caused the pneumocystis epidemic?
The epidemics spread likely due to infected glass syringes and needles. Malnutrition was not considered a cause, especially because the epidemics were at their height in the 1950s. At that time war torn Europe had already recovered from devastation. Researchers state that the most likely cause was a retrovirus closely related to HIV (or a mild version of HIV) brought to Europe and originating from Cameroon, a former German colony. The epidemic started in the Free City of Danzig in 1939 and then spread to nearby countries in the 1940s and 1950s, like Switzerland and The Netherlands.
