A tiny proportion of HIV-positive people--called elite controllers--maintains an undetectable viral load
without taking antiretroviral therapy.
The viral load
is tested every few months, enabling drugs to be switched as soon as they stop suppressing the virus.
South Africa was considered separately because of its relatively better health system than other countries in the area; there, the average viral load
was about 50% or 1.
Genital tract HIV-1 RNA shedding among women with below detectable plasma viral load
They compared viral load
measurements by using the current standard of frozen plasma and the alternative method of dried blood spots (DBS).
for up to 5 years, looking at changes in their vaginal bacteria as well as changes in the vaginal viral load
and their plasma viral load
Unfortunately, because the only commercially available tools for assessing HIV viral load
are those that look at RNA shedding in plasma, we use plasma viral load
as a surrogate for how infectious a given patient is, yet this may not always reflect what is happening in the genital tract.
The socalled baseline viral load
was the premalaria value measured 1 month before the first observation in the analysis.
To insure there is broad access to viral load
testing throughout the developing world it was logical to align our service testing menu with the market leader in viral load
The trial was stopped because some of these volunteers had a poor antiviral response to TMC125; those in the control group, who were treated with protease inhibitors instead, did better in reducing viral load
1 log drop in viral load
in the subset of patients not using 3TC or FTC in their background treatment regimen.
Study of Videx (didanosine, ddI) and hydroxyurea shows decreased viral load
in patients with HIV
