Promoting Awareness of Data Confidentiality and Security During the COVID-19 Pandemic in a Low-Income Country-Sierra Leone.

Objectives: World Health Organization issued Joint Statement on Data Protection and Privacy in the COVID-19 Response stating that collection of vast amounts of personal data may potentially lead to the infringement of fundamental human rights and freedoms. The Organization for Economic Cooperation and Development called on national governments to adhere to the international principles for data security and confidentiality. This paper describes the methods used to assist the Ministry of Health in bringing awareness of the data ownership, confidentiality and security principles to COVID-19 responders.

Improvement in Infection Prevention and Control Compliance at the Three Tertiary Hospitals of Sierra Leone following an Operational Research Study.

Implementing infection prevention and control (IPC) programmes in line with the World Health Organization's (WHO) eight core components has been challenging in Sierra Leone. In 2021, a baseline study found that IPC compliance in three tertiary hospitals was sub-optimal. We aimed to measure the change in IPC compliance and describe recommended actions at these hospitals in 2023.

Progress Toward Poliovirus Containment Implementation - Worldwide, 2019-2020.

Since 1988, when World Health Organization (WHO) Member States and partners launched the Global Polio Eradication Initiative, the number of wild poliovirus (WPV) cases has declined from 350,000 in 125 countries to 176 in only two countries in 2019 (1). The Global Commission for the Certification of Poliomyelitis Eradication (GCC) declared two of the three WPV types, type 2 (WPV2) and type 3 (WPV3), eradicated globally in 2015 and 2019, respectively (1). Wild poliovirus type 1 (WPV1) remains endemic in Afghanistan and Pakistan (1).

Progress Toward Poliovirus Containment Implementation - Worldwide, 2018-2019.

Among the three wild poliovirus (WPV) types, type 2 (WPV2) was declared eradicated globally by the Global Commission for the Certification of Poliomyelitis Eradication (GCC) in 2015. Subsequently, in 2016, a global withdrawal of Sabin type 2 oral poliovirus vaccine (OPV2) from routine use, through a synchronized switch from the trivalent formulation of oral poliovirus vaccine (tOPV, containing vaccine virus types 1, 2, and 3) to the bivalent form (bOPV, containing types 1 and 3), was implemented. WPV type 3 (WPV3), last detected in 2012 (1), will possibly be declared eradicated in late 2019.

Applying a New Framework for Public Health Systems Recovery following Emergencies and Disasters: The Example of Haiti following a Major Earthquake and Cholera Outbreak.

Emergencies can often directly impact health systems of an affected region or country, especially in resource-constrained areas. Health system recovery following an emergency is a complex and dynamic process. Health system recovery efforts have often been structured around the World Health Organization's health systems building blocks as demonstrated by the Post-Disaster Needs Assessment.

Formaldehyde Levels in Traditional and Portable Classrooms: A Pilot Investigation.

The pilot study discussed in this article assessed formaldehyde levels in portable classrooms (PCs) and traditional classrooms the authors evaluated formaldehyde levels in day and overnight indoor air (TCs) and explored factors influencing indoor air quality (e.g., carbon dioxide, temperature, and relative humidity).

Epidemic cholera in a crowded urban environment, Port-au-Prince, Haiti.

We conducted a case-control study to investigate factors associated with epidemic cholera. Water treatment and handwashing may have been protective, highlighting the need for personal hygiene for cholera prevention in contaminated urban environments. We also found a diverse diet, a possible proxy for improved nutrition, was protective against cholera.

Evaluating and regulating lead in synthetic turf.

Background: In 2007, a synthetic turf recreational field in Newark, New Jersey, was closed because lead was found in synthetic turf fibers and in surface dust at concentrations exceeding hazard criteria. Consequently, public health professionals across the country began testing synthetic turf to determine whether it represented a lead hazard. Currently, no standardized methods exist to test for lead in synthetic turf or to assess lead hazards.

Framing the problem: injuries and public health.

Objectives: To introduce the field of injury control and public health approaches to injury prevention.

Methods: A review of injury epidemiology, definitions, intervention approaches, and the importance of injury as a public health problem.

Results: Injuries are a large national and international problem affecting families and communities.

CDC's research portfolio in older adult fall prevention: a review of progress, 1985-2005, and future research directions.

Problem: Falls are a leading cause of mortality and morbidity among adults age 65 and older. Population models predict steep increases in the 65 and older population bands in the next 10-15 years and in turn, public health is bracing for increased fall rates and the strain they place on health care systems and society. To assess progress in fall prevention, the Centers for Disease Control and Prevention conducted a research portfolio review to examine the quality, relevance, outcomes and successes of the CDC fall prevention program and its impact on public health.

ATSDR evaluation of health effects of tungsten and relevance to public health.

The Agency for Toxic Substances and Disease Registry prepares toxicological profiles, as part of its mandate, on hazardous chemicals found at Comprehensive Environmental Response, Compensation, and Liability Act National Priorities List sites that have the greatest public health impact. These profiles comprehensively summarize toxicological and environmental information. This article constitutes the release of portions of the Toxicological Profile for tungsten.

Lead and delta-aminolevulinic acid dehydratase polymorphism: where does it lead? A meta-analysis.

Background: Lead poisoning affects many organs in the body. Lead inhibits delta-aminolevulinic acid dehydratase (ALAD), an enzyme with two co-dominantly expressed alleles, ALAD1 and ALAD2.

Objective: Our meta-analysis studied the effects of the ALAD polymorphism on a) blood and bone lead levels and b) indicators of target organ toxicity.
