ABSTRACT

RATIONALE: Some biomarkers of host response to viral infection are associated with COVID-19 outcomes, but these biomarkers do not directly measure viral burden. The association between plasma viral antigen levels and clinical outcomes has not been previously studied. Our aim was to investigate the relationship between plasma SARS-CoV-2 viral antigen concentration and proximal clinical deterioration in hospitalized patients. METHODS: SARS-CoV-2 nucleocapsid antigen concentrations were measured using a validated microbead immunoassay (Quanterix, NIH/NIAID laboratory) in plasma collected at enrollment from 256 subjects in a prospective observational cohort of hospitalized patients with COVID-19 from 3 hospitals, admitted between March 2020 and August 2021. Relationships between viral antigen concentration and clinical status at 1 week as measured by the World Health Organization (WHO) ordinal scale as well as ICU admission were assessed. Models were adjusted for age and sex, baseline comorbidities including immunosuppression, endogenous neutralizing antibodies, baseline COVID-19 severity, smoking status, remdesivir therapy, steroid therapy, and vaccine status. Missing covariate data were imputed using multiple imputation by chained equations. RESULTS: The median viral antigen concentration for the 35 subjects who deteriorated by 1 week was 4507 (IQR 1225-9665) pg/mL compared to 494 (IQR 18-3882) pg/mL in the 212 subjects who did not (p = 0.0004 Figure a). Using ordinal regression, each doubling in viral antigen concentration was significantly associated with a worse WHO ordinal scale at 1 week (unadjusted OR 1.07, 95% CI 1.02-1.13;adjusted OR 1.10, 95% CI 1.02-1.18). Among 168 patients not in the ICU at baseline, the median viral antigen concentration for the 40 patients who progressed to the ICU was 4697 (IQR 482- 10410) pg/mL vs. 459 (IQR 15-3062) pg/mL in the 128 patients who did not progress to require ICU care (p = 0.0001 Figure b). Using logistic regression, each doubling in viral antigen concentration was significantly associated with ICU admission (unadjusted OR 1.18, 95% CI 1.06-1.32, adjusted OR 1.40, 95% CI 1.11-1.76). CONCLUSIONS: Higher plasma viral antigen concentration at hospital admission is independently associated with a significantly worse clinical status at 1 week and a higher odds of ICU admission among hospitalized patients with COVID-19. This novel finding indicates that plasma viral antigen concentration may identify hospitalized COVID-19 patients at highest risk of short-term clinical deterioration in both clinical practice and research. Results of plasma antigen tests are available within 2-3 hours and could be integrated for identifying hospitalized COVID-19 patients who might benefit from early intervention.

ABSTRACT

The Delta variant of concern of SARS-CoV-2 has spread globally causing large outbreaks and resurgences of COVID-19 cases1-3. The emergence of Delta in the UK occurred on the background of a heterogeneous landscape of immunity and relaxation of non-pharmaceutical interventions4,5. Here we analyse 52,992 Delta genomes from England in combination with 93,649 global genomes to reconstruct the emergence of Delta, and quantify its introduction to and regional dissemination across England, in the context of changing travel and social restrictions. Through analysis of human movement, contact tracing, and virus genomic data, we find that the focus of geographic expansion of Delta shifted from India to a more global pattern in early May 2021. In England, Delta lineages were introduced >1,000 times and spread nationally as non-pharmaceutical interventions were relaxed. We find that hotel quarantine for travellers from India reduced onward transmission from importations;however the transmission chains that later dominated the Delta wave in England had been already seeded before restrictions were introduced. In England, increasing inter-regional travel drove Delta's nationwide dissemination, with some cities receiving >2,000 observable lineage introductions from other regions. Subsequently, increased levels of local population mixing, not the number of importations, was associated with faster relative growth of Delta. Among US states, we find that regions that previously experienced large waves also had faster Delta growth rates, and a model including interactions between immunity and human behaviour could accurately predict the rise of Delta there. Delta's invasion dynamics depended on fine scale spatial heterogeneity in immunity and contact patterns and our findings will inform optimal spatial interventions to reduce transmission of current and future VOCs such as Omicron.

ABSTRACT

The scale of data produced during the SARS-CoV-2 pandemic has been unprecedented, with more than 5 million sequences shared publicly at the time of writing. This wealth of sequence data provides important context for interpreting local outbreaks. However, placing sequences of interest into national and international context is difficult given the size of the global dataset. Often outbreak investigations and genomic surveillance efforts require running similar analyses again and again on the latest dataset and producing reports. We developed civet (cluster investigation and virus epidemiology tool) to aid these routine analyses and facilitate virus outbreak investigation and surveillance. Civet can place sequences of interest in the local context of background diversity, resolving the query into different 'catchments' and presenting the phylogenetic results alongside metadata in an interactive, distributable report. Civet can be used on a fine scale for clinical outbreak investigation, for local surveillance and cluster discovery, and to routinely summarise the virus diversity circulating on a national level. Civet reports have helped researchers and public health bodies feedback genomic information in the appropriate context within a timeframe that is useful for public health.
