In AIDS patients receiving effective antiviral therapy, if the treatment is successful, the level of plasma virus will drop rapidly until the range that our existing detection reagents can not detect.
we call it “below the detection limit”. It can reach the virus level below the detection limit within a certain period of time after treatment, which is a sign of successful antiviral treatment.
at this time, the infectivity of patients will be greatly reduced. A large number of studies have shown that the risk of HIV transmission is very low if the viral load in plasma is maintained at an undetectable level for more than six months.
on the one hand, even if the medication compliance is very good, 15% – 25% of patients may have a transient increase of viral load in plasma once or several times after virus control. This increase lasts for a short time and can be alleviated by itself, but the underlying mechanism is not very clear.
although scientists and doctors currently believe that this phenomenon does not affect the long-term treatment effect, after all, it is impossible to monitor the virus level in real time, and there is no way to predict when there will be a transient virus fluctuation. Therefore, it is still the best choice to adhere to protective measures.
after antiviral treatment, if the viral load control is not satisfied and no protective measures are taken, the risk of further transmission of the virus is greater. After taking X-ray to discover pregnancy, can the child still want it? The doctor told you so
