TasP (Treatment as Prevention) – a term to emphasise the impact that HIV drugs (ART) has on dramatically reducing the chance of HIV transmission.
ART is firstly for the health of the HIV positive person. But having an undetectable viral load on ART makes it so difficult to transmit HIV that the risk gets so close to zero that it is effectively zero.
For example, in the PARTNER study, nearly 900 couples had sex more than 58,000 times without condoms, without any transmissions. Each couple included one person who was HIV positive with an undetectable viral load on ART and one person who was HIV negative. ZERO transmissions.
diagnosis – identifying the cause of an illness.
partially active – the HIV treatment in question will work against this virus but this is reduced compared to wild-type HIV. This is the same as partial resistance, or intermediate resistance etc.
compensatory mutation – this refer to an additional mutation, usually in the context of the fitness of a virus. For example, the mutations that stop a drug form working often stop the virus from reproducing as well. Additional mutations that return the virus to it’s former fitness are called compensatory mutations. They compensate for the reduced viral fitness. See revertant mutation.
QD (or qd) – a short hand term for medication dosing that means ‘once-daily’.
