| Wasting Syndrome | |
The involuntary weight loss of 10 percent of baseline body weight plus either chronic diarrhea (two loose stools per day for more than 30 days) or chronic weakness and documented fever (for 30 days or more, intermittent or constant) in the absence of a concurrent illness or condition other than HIV infection that would explain the findings. | |
| Western Blot | |
A test for detecting the specific antibodies to HIV in a person's blood. It is commonly used to verify positive EIA tests. A Western Blot test is more reliable than the EIA, but it is more difficult and more costly to perform. All positive HIV antibody tests should be confirmed with a Western Blot test. | |

HIV that has not been exposed to antiviral drugs and therefore has not accumulated mutations conferring drug resistance. | |
