Understanding HIV Viral Load [PDF]

Canadian Journal of Public Health, 2008
This paper provides an overview of HIV viral loads in blood and genital fluids and how these relate to HIV transmission during sexual activity. Current knowledge around HIV viral loads and transmission are then discussed in relation to HIV disclosure laws in Canada.

Saliva viral load is a dynamic unifying correlate of COVID-19 severity and mortality

medRxiv, 2021
While several clinical and immunological parameters correlate with disease severity and mortality in SARS-CoV-2 infection, work remains in identifying unifying correlates of coronavirus disease 2019 (COVID-19) that can be used to guide clinical practice.

Association between upper respiratory tract viral load, comorbidities, disease severity and outcome of patients with SARS-CoV-2 infection

Journal of Infectious Diseases, 2021
Background There is limited information on the association between upper respiratory tract (URT) viral loads, host factors, and disease severity in SARS-CoV-2 infected patients. Methods We studied 1,122 patients (mean age: 46 years) diagnosed by PCR. URT

Impact of Severe Acute Respiratory Syndrome Coronavirus 2 Viral Load on Risk of Intubation and Mortality Among Hospitalized Patients With Coronavirus Disease 2019

Clinical Infectious Diseases, 2020
Background Patients hospitalized with coronavirus disease 2019 (COVID-19) frequently require mechanical ventilation and have high mortality rates. However, the impact of viral burden on these outcomes is unknown.

SARS-CoV-2 viral RNA levels are not 'viral load' [PDF]

Trends in Microbiology, 2021
Ct values are commonly used as proxy of SARS-CoV-2 “viral load”. Because of the (+)ssRNA nature of coronaviruses, current RT-qPCR target amplification does not distinguish replicative from transcriptional RNA. Although Ct values analyses through time, space and biological backgrounds remain informative, equating Ct with viral load may generate ...

Decreased SARS-CoV-2 viral load following vaccination

medRxiv, 2021
Beyond their substantial protection of individual vaccinees, it is hoped that the COVID-19 vaccines would reduce viral load in breakthrough infections thereby further suppress onward transmission.

Analysis of influencing factors of viral load in patients with high-risk human papillomavirus

Virology Journal, 2021
Background High-risk human papillomavirus (HR-HPV) load is thought to be influenced by many factors, and the relationship between viral load and the degree of cervical lesion is controversial.

Viral load and clinical features in children infected with seasonal influenza B in 2006/2007

Journal of the Formosan Medical Association, 2012
In influenza B infection, viral load is believed to be related to the severity of clinical illness. The correlation between viral load and symptoms is not known.
