Background: Intestinal parasitic infections are a significant public health concern, especially among food handlers, who can transmit these infections to the public through food preparation and handling. This systematic review and meta-analysis aimed to determine the pooled prevalence and associated factors of intestinal parasitic infections among food handlers in the East African region.
Methods: A systematic review and meta-analysis on intestinal parasitic infections among food handlers involved a comprehensive search across various databases, including Scopus, PubMed, ScienceDirect, Google Scholar, and the institution's library registers.
Background: Diabetes mellitus (DM) is a metabolic abnormality affecting 537 million people worldwide. Poor glycemic control, longer duration, and poor medication adherence increased the risk of DM complications. Comprehensive evidence on the pooled prevalence of microvascular complications in DM patients in Ethiopia is not available.

- A systematic review and meta-analysis was conducted to estimate the prevalence of pulmonary tuberculosis (PTB) among key and vulnerable populations (KVPs) in hotspot regions of Ethiopia, despite a global decline in TB incidence.
- The analysis included 34 articles, with methods involving data recorded and analyzed using STATA 17.0, assessing prevalence rates by various group settings and publication years.
- The findings estimated a pooled PTB prevalence of 11.7% in hotspot settings, with specific prevalence rates for different KVPs: prison inmates (8.8%), university students (23.1%), refugees (28.4%), and others, highlighting significant vulnerability among these groups.
Article Synopsis
- - The study investigates the prevalence of carbapenem-resistant gram-negative bacteria that cause neonatal sepsis in African newborns, as this issue is a growing concern globally.
- - A total of 36 research studies were analyzed, revealing a combined prevalence rate of 30.34% for carbapenem resistance among these bacteria in Africa.
- - Specifically, A. baumannii and Pseudomonas species showed high resistance rates, with 45.9% and 43.0% prevalence, respectively, indicating a significant public health challenge.
Background: Antimicrobial-resistant (AMR) bacterial infection is a significant global threat to the healthcare systems. Pseudomonas aeruginosa, the leading infectious agent in the healthcare setting is now one of the major threats due to AMR. A comprehensive understanding of the magnitude of AMR, particularly highly public health important pathogens such as P.

Methods: Review of blood film reports from health institutions' laboratory record books using predesigned checklists was done as part of an institution-based retrospective study to assess the 5-year (2016/2017-2020/2021) trend of malaria. To display data and analyse patterns in the trend of malaria over the course of years, months and seasons, descriptive statistics were used.
Background: While rapid diagnostic tests are an alternative diagnostic tests for microscopy in the diagnosis of malaria in rural settings, their performance has been inconsistent. Performance of rapid diagnostic tests might be affected by manufacturing process, transportation and storage, parasitemia level, and skill of personnel who perform the tests. Therefore, periodic evaluation of the local field performance of rapid diagnostic tests is mandatory in order to make early corrections in case of decreased performance.

- A study in Bahir Dar Zuria district, Ethiopia, assessed malaria prevalence and community knowledge about the disease among 149 febrile patients from January to March 2020.* -
- Results showed that 14.8% of participants tested positive for malaria, with varying prevalence rates for different species and indicators of community knowledge, attitude, and practice.* -
- Significant relationships were found between knowledge and factors like age, education, and family size, with those from smaller families more likely to have negative attitudes toward malaria.*
Background: In Ethiopia, anti-malaria treatment is initiated after parasitological confirmation using blood film microscopy at health centers and hospitals, or serological rapid diagnostic tests at health posts. At health posts, the diagnosis is performed by health extension workers using rapid diagnostic tests after little training. However, there is paucity of data about the health extension workers' performance on rapid diagnostic tests.

- Anopheles mosquitoes are the main carriers of malaria, and this study focuses on their presence in the Amhara region of Ethiopia, specifically in Bahir Dar city.
- The research conducted from January to July 2020 involved setting up light traps to collect adult female mosquitoes for identification and to assess their reproductive and infection rates.
- Three species were identified, with Anopheles rhodesiensis being the most common at one site and An. gambiae complex dominating another; overall, the parous rate was 62.5% and the infection rate was 2.9%.
