Monkeypox: Early Estimation of Basic Reproduction Number R0 in Europe

alexandrossfakianakis shared this article with you from Inoreader Monkeypox: Early Estimation of Basic Reproduction Number R0 in Europe via Journal of Medical Virology Abstract This world outbreak of Monkeypox-MPX infections outside Africa emerged on May 2022 in Europe and spread worldwide with unique characteristics: inter-human contagion and infection in men without specific previous immunization, prevalently men-having-sex-with-men MSM. Phylogenetic analysis confirmed a unique clade, the West African clade, subclade IIb. On August 30, WHO stated 48,895 laboratory confirmed cases from 101 different countries, of which 28,050 were in Europe. It has therefore become important to define new epidemiological indices. Starting from our new surveillance system EpiMPX open data, we defined an early R0 measure, using European ECDC confirmed cases from the epidemic start to the end of August 2022; our early R0 pooled median is 2.44, with high variability between countries. We observed the higher R0 in Portugal and Germany, followed by Italy, Spain and France. Anyway, these high estimates refer to the MSM gr oup rather than to the general population. Early estimation of R0 can be used to support the epidemiological understanding of transmission dynamics and contain MPX from spreading in naive populations and core groups with risk factors. MPX is in an evolving situation with much to learn and to do to combat the current epidemic outbreak. This article is protected by copyright. All rights reserved. View on Web
