- Angola reported its first poliomyelitis case in six years, involving circulating vaccine-derived poliovirus type 2 (cVDPV2), with a total of 141 cases across the country from 2019 to 2020, particularly in Luanda, Cuanza Sul, and Huambo.
- The spread of cVDPV2 followed five distinct genetic emergence groups linked to earlier cases in the Democratic Republic of Congo, with a peak of 15 cases occurring in October 2019.
- Despite challenges in surveillance due to the COVID-19 pandemic, by May 2021, evidence indicated that Angola had successfully interrupted cVDPV2 transmission, but improvements in surveillance and response measures were needed for any future outbreaks.
Background: The aim of the present study was to investigate how the organisation of healthcare activity during the first wave of the SARS-CoV-2 pandemic affected the timing of diagnosis of oral carcinoma in the Functional Head and Neck Department of Padua (Italy). This study gives an effective temporal dimension of the diagnostic delay that occurred during the pandemic, compared with data from the literature.
Methods: A retrospective analysis of the diagnostic path of a patient affected by oral cancer during COVID-19 pandemic was performed.
Food animals may be reservoirs of antimicrobial resistance (AMR) passing through the food chain, but little is known about AMR prevalence in bacteria when selective pressure from antimicrobials is low or absent. We monitored antimicrobial-resistant over 1 year in a UK outdoor pig farm with low antimicrobial usage (AMU) compared to conventional pig farms in the United Kingdom. Short and selected long-read whole-genome sequencing (WGS) was performed to identify AMR genes, phylogeny and mobile elements in 385 isolates purified mainly from pig and some seagull faeces.

Antimicrobial-resistant is becoming an extremely important global health problem. A cross-sectional study was conducted from December 2019 to May 2020 to assess the occurrence of and its antimicrobial susceptibility profiles in milk and traditionally processed dairy products in selected subcities of Addis Ababa.
