The development of infrastructure, a rapidly increasing population, and urbanization has resulted in increasing air pollution levels in the African city of Addis Ababa. Prior investigations into air pollution have not yet sufficiently addressed the sources of atmospheric particulate matter. This study aims to identify the major sources of fine particulate matter (PM) and its seasonal contribution in Addis Ababa, Ethiopia.

Unlabelled: Real-time monitoring of fine particulate matter (PM) concentrations and assessing the health impact are limited in Ethiopia. The objective of this study is to describe current levels of PM air pollution in Addis Ababa and examine temporal patterns and to consider the health impact of current PM exposure levels.

Methods: PM concentrations were measured using a centrally-located Beta Attenuator Monitor (BAM-1022) for 3 years (1 April 2017 to 31 March 2020), with data downloaded biweekly.

Background: Computer vision syndrome (CVS) is an amalgam of visual symptoms caused by continued use of computers. Worldwide, up to 70 million workers are at risk for computer vision syndrome resulting in reduced productivity at work and reduced quality of life. Bank employees are among the risky workers with unknown magnitude of the syndrome.

Ambient air pollution is a growing public health concern in major African cities, including Addis Ababa (Ethiopia), where little information is available on fine particulate matter (PM, with aerodynamic diameter <2.5 µm) pollution. This paper aims to characterize annual PM, including bulk composition and seasonal patterns, in Addis Ababa.

Background: The incidence of newborn and young infant health danger signs is unknown in Ethiopia. Neverthe- less, experience shows that care-seeking is far lower than conservative morbidity estimates would project.

Objectives: To examine illness recognition, home care, decision-making, and care-seeking for sick infants less than two months of age in Shebedino District, Southern Nations, Nationalities and Peoples Region in 2011.

Background: Use and coverage of curative interventions for childhood pneumonia, diarrhea, and malaria were low in Ethiopia before integrated community-based case management (iCCM).

Objectives: To examine factors accounting for low use of iCCMin Shebedino District applying a "Pathway to Sur- vival" approach to assess illness recognition; home care; labeling and decision-making; patterns of care-seeking; access, availability and quality of care; and referral.

Methods: Shortly after introduction of iCCM, we conducted five studies in Shebedino District in May 2011: a population-based household survey; focus group discussions of mothers of recently ill children; key informant in- terviews, including knowledge assessment, with Health Extension Workers at health posts and with health workers at health centers; and an inventory of drugs, supplies, and job aids at health posts and health centers.

Background: Collection of household waste is a job which requires repeated heavy physical activities such as lifting, carrying, pulling, and pushing. Like many developing countries, in Ethiopia municipal solid waste is collected manually. Therefore, this study is aimed to assess the extent of occupational injuries and associated factors among solid waste collectors in Addis Ababa City.

The unique Ethiopian cultural tradition of the coffee ceremony increases inhalation exposures to combustion byproducts. This pilot study evaluated exposures to particulate matter and carbon monoxide in ten Addis Ababa homes during coffee ceremonies. For coffee preparers the geometric mean (57 μg/m³) and median (72 μg/m³) contributions to an increase in a 24-hour time-weighted average exposure were above World Health Organization (WHO) guidelines.
