Although haart therapy only kills free floating HIV virus, won't the dormant reservoirs eventually die off leaving the person free of hiv?

Although haart therapy only kills free floating HIV virus, won't the dormant reservoirs eventually die off leaving the person free of hiv?

Dormant HIV: Unfortunately, some of the cells the virus infects can lie 'dormant' for >13 years. Our hope was that treating the virus would rid our patients of the infection in time but we need to make those latent cells infected w/virus 'apoptose' or die ; prevent new immature cells from being infected. It has been more difficult than we anticipated but work is actively being done. We have hope! ...Read more

After infected by Rabies, during incubation period but prior to brain being infected, having rabies vaccine can help the patient survive?

After infected by Rabies, during incubation period but prior to brain being
 infected, having rabies vaccine can help the patient survive?

Yes: A person infected with rabies will not show ill signs at first. If he doesn't get rabies shots, the virus will travel to his brain. The incubation period from the time of infection until the signs and symptoms show up, is variable (about 3 weeks to 3 months). The last chance to get rabies shots and not die, is uncertain but is some time before any symptoms appear. ...Read more
