Investigating antibody cross-reactivity and transmission dynamics of alphaviruses and flaviviruses using a multiplex serological assay - Nature Communications Arboviruses often co-circulate, but cross-reactivity hampers serological diagnostics. Here, the authors paired multiplex serology with competitive immunoassays and Bayesian modelling to quantify antib...

Excited to share our new paper out today in @natcomms.nature.com
Combining multiplex serology, mathematical modelling, and experimental validation reveals arbovirus transmission dynamics despite cross-reactivity. (1/2)

In Apr-Jun, transmissions concentrated around Paris, mostly with short-range events. In Jul-Sep, long-range transmissions drove the spread to the north, where local hubs formed. Mean transmission distance declined in Oct. We estimate cholera was introduced in 10 major ports from outside France.

Spread was well captured by a gravity model, highlighting human mobility's role. Transmission rose by 2.5-fold in Aug., compensated by a drop in duration of infectivity of municipalities, likely due to interventions. Commercial ports played a key role both as points of introduction/local hubs.

The epidemic started in April in Paris area and expanded mostly to the North of France, with a peak in September. Infected municipalities clustered around major commercial ports.

The report provides a linelist of >4000 cholera deaths that occurred across France, along with detailed descriptions of control measures and maps documenting local outbreaks.

Modeling the spatio-temporal spread of cholera in France in 1892 From an historical perspective, it is important to understand how past epidemics spread; but such a task is complicated by limited data availability. …

Few years ago, an intern in the team explored historical archives and identified a fascinating report describing with great detail the large French cholera epidemic of 1892. The modelling analysis of these data has now been published in Epidemics.
