Post-doc position a Institute Pasteur modeling COVID. I can't think of a better place to work!

Progress towards better serological SARS-CoV-2 tests . New data from our multiplex assay: 98.8% sensitivity (CI: 96.5%, 99.6%) & 99.3% specificity (CI: 97.6%, 99.8%) validated on 594 samples.

Yes, important point. This was primary-school children. Similar study in highschool nearby found high (38%) and comparable levels with teachers (43%) and lower in parents (11%) - unfortunately not broken down by status of child. Seems reduced infectivity in younger children only

Key schoolkid serostudy w sensitive assay. 9% infected-most(61%) positives had positive parents (other parents:7%, teachers:3%). Points to adults as infectors, reduced child infectivity, limited school transmission. Lower child susceptibility still unclear

COVID contact tracing results from Italy. Of particular interest is that proportion of contacts <20y testing positive is similar to 20-60y, suggesting similar susceptiblility. Would be useful to have more detailed age breakdown.

Important data showing short duration of antibody-mediated immunity to seasonal coronaviruses. Large reductions in Ab levels in 12 months and frequent re-infection.

What did we learn from weekly SARS-CoV-2 serosurveys in Geneva? First, like most places with serosurvey results, the vast majority of the population does not seem to have IgG antibodies. (1/n)

If you consider that nursing home deaths represent ~0% of all deaths in some countries (S Korea) and >70% in others (Canada), I’d advocate stripping out nursing homes from numerator and denominator when presenting headline IFR figure to help comparisons.

Results show chikungunya circulated briefly, infecting 20% of the population whereas mayaro spills over yearly with ~200 human infections/y. Data is from fantastic nationally representative serostudy conducted by and Dominique Rousset at InstitutPasteur Guiana

Using Mayaro and chikungunya viruses in French Guiana as an example, we show analyzing serological data from related viruses simultaneously allows us to better characterize spread than when pathogens are considered separately.

Are SARS-CoV-2 seroprevalence estimates biased? Pre-print with and . Short answer: We need data on the sensitivity of serological assays to detect asymptomatic and mild infections! Thread 1/10

This is a very nice idea. I’ve always battled with how to present uncertainty in maps - this seems like a good solution.

A good summary of potential reasons for the small no. of detected cases in children. I would add that study design/analyses to explore this should allow for potentially shorter PCR windows and lower (later?) Ab responses - It seems potentially easy to miss infections in kids

Early serology results based on antibody testing: 5% for UK, 17% for London. From Matt Hancock, Health Secretary in today's briefing. In line with what other countries have reported on their seroprevalence.

As Nipah virus disease severity increases, so do the number of daily contacts. This has implications for transmission as viral loads potentially greatest in these late stages.
