Midieron anticuerpos contra cuatro filovirus, incluido el de Bundibugyo, que causa el brote actual. Buscaban ver dónde hubo contacto histórico con estos virus.","fuente":"medrxiv","fuenteNombre":"medRxiv · preprints","color":"#1f7a4d","autor":"Merritt, S., Kompany, J.

While the DRC has recorded 18 filovirus disease outbreaks, the historical frequency and geographic distribution of human filovirus exposures remain poorly understood. Using a multiplexed multi-filovirus immunoassay, we assessed antibody reactivity against antigens of filoviruses linked to human disease, Bundibugyo virus (BDBV), Ebola virus (EBOV), Marburg virus (MARV), and Sudan virus (SUDV), among eleven cohorts from seven provinces between 2015-2023 (n=5,852).
