Article Synopsis
- Echovirus 11 is causing increasing cases of neonatal sepsis in Europe and limited reports in West Africa, highlighting a significant public health issue.
- A study analyzed 23 E11 strains from West Africa using high-throughput sequencing, marking the first molecular characterization of the virus in the region and revealing a new recombinant strain.
- The research indicates that E11 has evolved into four distinct clades since the 1970s, with instances of the virus spreading from West Africa to Europe, underscoring the need for enhanced surveillance of enteroviruses in Africa.
Objectives: Several factors can cause acute flaccid paralysis cases including non-polio enteroviruses. In Senegal, few studies on non-polio enteroviruses (NPEV) have been performed.
Methods: Our study assess the molecular epidemiology of non-polio enteroviruses in Senegal from 2013 to 2021 through the previously existing programs for surveillance of polioviruses.
We explored the between-group and temporal variations in the intestinal populations of broilers under experimental conditions, taking both antimicrobial resistance and virulence into consideration. Four replicates of 45 commercial chicks were reared in four animal facilities. On their first day of life (Day 0), they were orally inoculated with two extended-spectrum-cephalosporin-resistant (ESCR) (2.

Following the 2014 outbreak, active surveillance of the EV-D68 has been implemented in many countries worldwide. Despite subsequent EV-D68 outbreaks (2014 and 2016) reported in many areas, EV-D68 circulation remains largely unexplored in Africa except in Senegal, where low levels of EV-D68 circulation were first noted during the 2014 outbreak. Here we investigate subsequent epidemiology of EV-D68 in Senegal from June to September 2016 by screening respiratory specimens from ILI and stool from AFP surveillance.

Background: To analyze the impact of the International Nosocomial Infection Control Consortium (INICC) Multidimensional Approach (IMA) and use of INICC Surveillance Online System (ISOS) on ventilator-associated pneumonia (VAP) rates in Saudi Arabia from September 2013 to February 2017.
Methods: A multicenter, prospective, before-after surveillance study on 14,961 patients in 37 intensive care units (ICUs) of 22 hospitals. During baseline, we performed outcome surveillance of VAP applying the definitions of the CDC/NHSN.
