In nursing home residents with asymptomatic COVID-19 diagnosed through twice-weekly surveillance testing, single-dose BNT162b2 vaccination (Pfizer-BioNTech) was associated with -2.4 mean log10 lower nasopharyngeal viral load than detected in absence of vaccination (P = .004). Since viral load is linked to transmission, single-dose mRNA SARS-CoV-2 vaccination may help control outbreaks.

Human Immunodeficiency Virus Type 1 (HIV) set-point viral load is a strong predictor of disease progression and transmission risk. A recent genome-wide association study in individuals of African ancestries identified a region on chromosome 1 significantly associated with decreased HIV set-point viral load. Knockout of the closest gene, CHD1L, enhanced HIV replication in vitro in myeloid cells.

Trust in healthcare providers plays a significant role in adhering to ART and is likely lower among Black WLHIV compared to their White counterparts. This study examined the relationship between experienced stigma in healthcare settings and ART adherence and viral suppression through anticipated stigma in healthcare settings, internalized stigma, and medical mistrust.

The pathogenic potential of airborne particles carrying the SARS-CoV-2 viral genome was examined by considering the size distribution of airborne particles at given distances from the respiratory zone of an infected patient after coughing or sneezing with a focus on time, temperature, and relative humidity. The results show an association between the size distribution of airborne particles, particularly PM and PM, and the presence of viral genome in different stations affected by the distance from the respiratory zone and the passage of time. The correlation with time was strong with all the dependent factors except PM.

This study compared the dynamics of SARS-CoV-2 viral shedding in saliva between wild-type virus-infected and Omicron-infected household cohorts. Pre-existing immunity in participants likely shortens the viral RNA shedding duration and lowers viral load peaks. Frequent saliva sampling can be a convenient tool to study viral load dynamics.

Neutrophils play key protective roles in influenza infections, yet excessive neutrophilic inflammation is a hallmark of acute lung injury during severe infections. Phenotypic heterogeneity is increasingly recognized in neutrophil populations; however, how functional variation in neutrophils between individuals determine the diverse outcomes of influenza remains unclear. To examine immunologic responses that may drive varying outcomes in influenza, we infected C57BL/6 (B6) and A/J mice with mouse-adapted influenza A virus A/PR/8/34 H1N1.
