A century after its discovery, Chagas' disease still represents a major public health challenge in Latin America. Moreover, because of growing population movements, an increasing number of cases of imported Chagas'
...
disease have now been detected in non-endemic areas, such as North America and some European countries. This parasitic zoonosis, caused by Trypanosoma cruzi, is transmitted to humans by infected Triatominae insects, or occasionally by non-vectorial mechanisms, such as blood transfusion, mother to fetus, or oral ingestion of materials contaminated with parasites. Following the acute phase of the infection, untreated individuals enter a chronic phase that is initially asymptomatic or clinically unapparent. Usually, a few decades later, 40-50% of patients develop progressive cardiomyopathy and/or motility disturbances of the oesophagus and colon. In the last decades several interventions targeting primary, secondary and tertiary prevention of Chagas' disease have been attempted. While control of both vectorial and blood transfusion transmission of T cruzi (primary prevention) has been successful in many regions of Latin America, early detection and aetiological treatment of asymptomatic subjects with Chagas' disease (secondary prevention) have been largely underutilised. At the same time, in patients with established chronic disease, several pharmacological and non-pharmacological interventions are currently available and have been increasingly used with the intention of preventing or delaying complications of the disease (tertiary prevention). In this review we discuss in detail each of these issues.

ECDC Technical Report
In line with ECDC’s recommendations provided in the ’Risk Assessment of HTLV-1/2 transmission by tissue/cell transplantation’ dated 14 March 2012, this Directive replaces the term ‘incidence’ with ‘prevalence’ in the description of endemic areas of HTLV-1/2 i ... nfection. According to the new requirements ‘HTLV-1 antibody testing must be performed for donors living in, or originating from high-prevalence areas or with sexual partners originating from those areas or where the donor’s parents originate from those areas’ and this applies to both donors of non-reproductive tissues and cells and reproductive cells.
ECDC contracted experts from the Institut Pasteur in Paris to systematically review the published evidence on the distribution of HTLV-1 infection prevalence throughout the world and to identify high-prevalence countries and areas. more

Africa CDC and APHF are coordinating a continental initiative to maximize the benefits of molecular approaches and pathogen genomics for more effective
outbreak preparedness, prevention, response, and for the control and elimination of endemic diseases in Africa. One of Africa CDC’s flagship initiative is the Africa
Pathogen Genomics Initiative (Africa PGI), a partnership that aims to strengthen laboratory systems and enhance genomic surveillance by equipping the continent’s
public health institutions with the tools, training, and data infrastructure.
About the Project
In 2023, 166 outbreaks and public health events were reported in Africa. This calls for a resilient laboratory systems for timely detection and reporting of current and future outbreaks. This project aims to scale up molecular diagnostic and genomic sequencing-based detection and characterization of outbreaks.
Africa CDC is working with Member States to develop guidance, diagnostic algorithm, training and capacity building to enable outbreak detection, and reporting to inform public health response.

Infection prevention and control measures for Ebola virus disease
This document provides guidance on the application of non-pharmaceutical countermeasures to minimise the spread of the 2019 novel coronavirus (2019-nCoV) in the population. Some of the measures proposed refer specifically to certain phases of the epidemic (containment or mitigation phases), and can
...
be adapted depending on the assessed severity/impact of the infection. Other measures are valid for all phases of an epidemic.
The guidance is based on the current knowledge of the 2019-nCoV and evidence available on other viral respiratory pathogens, mainly the Severe Acute Respiratory Syndrome coronavirus (SARS-CoV), the Middle East Respiratory Syndrome-related coronavirus (MERS-CoV) and seasonal or pandemic influenza viruses.

Non-pharmaceutical interventions (NPI) are public health measures that aim to prevent and/or control SARS-CoV-2 transmission in the community. As long as there is no effective and safe vaccine to protect those at risk of severe COVID-19, NPI are the

most effective public health interventions against COVID-19. These ECDC guidelines detail available options for NPI in various epidemiologic scenarios, assess the evidence for their effectiveness and address implementation issues, including potential barriers and facilitators.

The Guideline for Disinfection and Sterilization in Healthcare Facilities, 2008, presents evidence-
based recommendations on the preferred methods for cleaning, disinfection and sterilization of patient-
care medical devices and for cleaning and disinfecting the healthcare environment. This docume
...
nt
supercedes the relevant sections contained in the 1985 Centers for Disease Control (CDC) Guideline for
Handwashing and Environmental Control. 1 Because maximum effectiveness from disinfection and
sterilization results from first cleaning and removing organic and inorganic materials, this document also
reviews cleaning methods. The chemical disinfectants discussed for patient-care equipment include
alcohols, glutaraldehyde, formaldehyde, hydrogen peroxide, iodophors, ortho-phthalaldehyde, peracetic
acid, phenolics, quaternary ammonium compounds, and chlorine. The choice of disinfectant,
concentration, and exposure time is based on the risk for infection associated with use of the equipment
and other factors discussed in this guideline. The sterilization methods discussed include steam
sterilization, ethylene oxide (ETO), hydrogen peroxide gas plasma, and liquid peracetic acid. When
properly used, these cleaning, disinfection, and sterilization processes can reduce the risk for infection
associated with use of invasive and noninvasive medical and surgical devices. However, for these
processes to be effective, health-care workers should adhere strictly to the cleaning, disinfection, and
sterilization recommendations in this document and to instructions on product labels.

ve prediabetes by taking the Prediabetes Risk Test. If your result shows you’re at high risk for type 2 diabetes, talk to your doctor about getting a simple blood sugar test to confirm it. Then, if you’re diagnosed with prediabetes, consider joining a lifestyle change program offered by the National Diabetes Prevention Program (National DPP). This program is proven to cut the risk for type 2 diabetes in half.

Crisis and Emergency Risk Communication is an approach to communicating effectively during emergencies. These principles are used by public health professionals and public information officers to provide information that helps individuals, stakeholders, and entire communities make the best possible
...
decisions for themselves and their loved ones. CERC recognizes that during emergencies, we work under impossible time constraints and must accept the imperfect nature of our choices. CERC draws from lessons learned during public health emergencies and research in the fields of public health and emergency risk communication.
The CERC program consists of 1) training, 2) resources, and 3) shared learning.
