Now that we can see a difference in something as concrete as the viral burden, it has to give us more intellectual humility and make us realize we don't really know what the virus is doing in there."
Monitoring a person's viral burden is important because of the apparent correlation between the amount of virus in the blood and the severity of the disease: sicker patients generally have more virus than those with less advanced disease.
I think there's a good rational for saying if you can identify these people and do treatment earlier, you can decrease the viral burden and decrease the reservoirs of infected cells in the body and probably alter the long-term course.
"Those who discontinue (therapy) at this time are at increased risk of developing a higher viral burden, resulting in greater infectiousness and higher levels of drug resistance, potentially creating reservoirs of drug-resistant HIV in the general community," the scientists said.
Treatment: The development of possible immunoglobulin therapy (currently underway in Hong Kong) and information on the viral burden (whether it peaks early or late during infection).
The increasing viral titres were noticed after 7 days and after 15 days.
The means by which nef increases HIV virulence and viral titre is still a subject of much research.

Summary While studies on the effectiveness of bleach in inactivating HCV are limited, laboratory studies do demonstrate that bleach can reduce viral titres sufficiently to reduce viral infectivity.
Payan et al. reported that sodium hypochlorite at 4700ppm free chlorine (approximately 1:11 dilution bleach) reduced viral titres 1000 to 10,000-fold, although more diluted concentrations were not effective, resulting in less than 10-fold viral reduction66.
It is anticipated that a strong immune capability based on cytotoxic T lymphocyte activity will greatly reduce viral titres so that those infected by HIV will live longer and be much less infective for others.
For example, CDC recommends adding indinavir (800 mg three times a day for 4 weeks) as the third drug for percutaneous exposures that involve both a large volume of blood and a source patient with high HIV viral titre (26).
The risk increases if the viral titre is higher, i.e. the HCW is 6.4 times more likely to become infected from a source patient with high viral load (end stage AIDS or acute retroviral illness) than from a patient with a low viral load(394).
The combined administration of three antiviral drugs is recommended in cases of high risk exposure when the HCW has been exposed to a large volume of blood, a source patient with high HIV viral titre, or a patient suspected of having a multi-drug resistant HIV strain(42).

• The viral titer in a sample was measured using a plaque assay on bovine turbinate cells.
Concentration of supernatant to viral titers exceeding 10 7cfu/ml appeared to have the greatest quantitative impact on improving transduction efficiency.
We designed experiments to determine if viral titer influenced FLS transduction by concentration of retrovirus.
This observation suggests that factors in addition to viral titer may limit the maximum number of transduced FLS observed using these culture conditions.
The basis for this resistance was unclear, but could be attributable to many factors including vector design, viral titer, or biologic features inherent to FLS.
Viral titer was quantitated by expression studies in NIH 3T3 cells (Supplementary Fig.
