New sequences from Eastern and Southern Africa alter our understanding of regional cholera transmission.

Despite ongoing containment and vaccination efforts, cholera remains prevalent in many countries in sub-Saharan Africa. Part of the difficulty in containing cholera comes from our lack of understanding of how it circulates throughout the region. To better characterize regional transmission, we generated and analyzed 118 genomes collected between 2007-2019 from five different countries in Southern and Eastern Africa.

Omicron B.1.1.529 variant infections associated with severe disease are uncommon in a COVID-19 under-vaccinated, high SARS-CoV-2 seroprevalence population in Malawi.

Background: The B.1.1.

Global Antimicrobial Resistance and Use Surveillance System on the African continent: Early implementation 2017-2019.

Background: Antimicrobial resistance (AMR) is becoming a critical public health issue globally. The World Health Organization launched the Global Antimicrobial Resistance and Use Surveillance System (GLASS) to support the strengthening of the AMR evidence base.

Objective: The article describes the evolution of national AMR surveillance systems and AMR data reporting of countries in the African continent between 2017 and 2019, and the constraints, perceived impact and value of the participation in GLASS.

National action plan on antimicrobial resistance: An evaluation of implementation in the World Health Organization Africa region.

In line with global instruments, within the last five years, two-thirds of all countries in the WHO Africa Region (WHO AFR) have developed a National Action Plan (NAP) on Antimicrobial Resistance (AMR). We sought to evaluate progress made across the countries implementing NAP for effective response to AMR. A semi-structured survey tool was administered to obtain information from national focal persons on the implementation of strategic elements of NAP on AMR.

A multidrug-resistant clinical isolate from Kamuzu Central Hospital, Malawi.

Background: is a significant opportunistic pathogen that is associated with high mortality in immunocompromised individuals. In this study, we describe a multidrug-resistant (MDR) clinical isolate from Kamuzu Central Hospital (KCH), Lilongwe, Malawi.

Methods: A ceftriaxone and meropenem nonsusceptible isolate (Sm-MW08), recovered in December 2017 at KCH, was referred to the National Microbiology Reference Laboratory for identification.

Field Evaluation of Cholkit Rapid Diagnostic Test for During a Cholera Outbreak in Malawi, 2018.

Rapid diagnostic tests (RDTs) for cholera are an important emerging tool for surveillance, yet the currently available tests have several limitations. We assess the performance of a new RDT, Cholkit, during a cholera outbreak in Malawi compared with culture and find a sensitivity of 93.0% (95% CI, 83.

Feasibility Study of the World Health Organization Health Care Facility-Based Antimicrobial Stewardship Toolkit for Low- and Middle-Income Countries.

Antimicrobial stewardship (AMS) has emerged as a systematic approach to optimize antimicrobial use and reduce antimicrobial resistance. To support the implementation of AMS programs, the World Health Organization developed a draft toolkit for health care facility AMS programs in low- and middle-income countries. A feasibility study was conducted in Bhutan, the Federated States of Micronesia, Malawi, and Nepal to obtain local input on toolkit content and implementation of AMS programs.

First Identification and genomic characterization of multidrug-resistant carbapenemase-producing clinical isolates in Malawi, Africa.

. Carbapenemase-producing (CPE) have become a global concern and a serious threat to human health due to their resistance to multiple antibiotics. In this study, we identified and characterized CPE for the first time in Malawi, southeastern Africa.

Whole genome sequence of Vibrio cholerae directly from dried spotted filter paper.

Background: Global estimates for cholera annually approximate 4 million cases worldwide with 95,000 deaths. Recent outbreaks, including Haiti and Yemen, are reminders that cholera is still a global health concern. Cholera outbreaks can rapidly induce high death tolls by overwhelming the capacity of health facilities, especially in remote areas or areas of civil unrest.

Effectiveness of oral cholera vaccine in preventing cholera among fishermen in Lake Chilwa, Malawi: A case-control study.

Background: In response to a cholera outbreak among mobile, difficult-to-reach fishermen on Lake Chilwa, Malawi in 2016, a novel vaccine distribution strategy exploited the proven vaccine thermostability. Fishermen, while taking the first vaccine dose under supervision, received the second dose in a sealed bag, and were told to drink it two weeks later. This study assessed short-term vaccine protection of this strategy.
