This threat assessment addresses the implications of the ongoing Marburg virus disease (MVD) outbreak in
Rwanda for the European Union/European Economic Area (EU/EEA). MVD is a severe disease in humans and,
although uncommon, it has the potential to cause epidemics with significant
...
case fatality. All recorded MVD
outbreaks to date have originated in Africa. MVD is not an airborne disease and is considered not to be
contagious before symptoms appear. Direct contact with the blood and other body fluids of infected people
and animals or indirect contact with contaminated surfaces and materials like clothing, bedding and medical
equipment is required for transmission. The risk of infection is minimised when proper infection prevention and
control precautions are strictly followed. There is no approved treatment or vaccine for MVD; however, several
pharmaceuticals and candidate MVD vaccines are under investigation.

WHO guideline on contact tracing
recommended
This practical guideline establishes definitions for “contact”, “contact person”, “contact tracing” and other associated concepts. It allows for improvement of contact tracing strategies and provides recommendations attempting to answer some, though not all, questions that arose during t
...
he 2019 coronavirus pandemic and other outbreaks. The use of this guideline begins once people have been diagnosed and the potential for transmission exists. It is not, however, intended to assist with case investigation. The guideline empowers health workers, governments, and public health officials with the tools to implement effective contact tracing strategies.

The document “Public Health Surveillance for Cholera – Guidance Document (2024)” provides practical recommendations for countries on how to design, implement, and strengthen cholera surveillance systems. Developed by the Global Task Force on Cholera Control (GTFCC), it outlines the minimum req

uirements for detecting, confirming, reporting, and monitoring cholera cases and outbreaks.
The guidance explains the core functions of cholera surveillance, including case detection, laboratory testing (such as RDTs, culture, and PCR), routine data collection, outbreak notification, case and field investigation, data analysis, and performance monitoring. It also describes how surveillance strategies should be adapted depending on whether a country is experiencing no outbreak, clustered transmission, or community transmission.
Overall, the document aims to help countries establish adaptive, fit-for-purpose surveillance systems that enable early outbreak detection, guide timely response measures, and support long-term cholera control and elimination efforts.

eedback mechanisms to improve the performance and quality of Integrated Disease Surveillance and Response (IDSR) systems. The text outlines key surveillance core functions—such as case detection, reporting, data analysis, outbreak investigation, preparedness, response, and feedback—and introduces indicators to measure system effectiveness, including timeliness, completeness, and data quality. Additionally, it discusses the implementation of electronic IDSR (eIDSR) to enhance real-time reporting and outbreak management. Overall, the booklet aims to strengthen early detection, rapid response, and health security capacity across all levels of the health system.

Child Friendly Spaces (CFSs) are used by humanitarian agencies as a means to promote protection and psychosocial wellbeing for children in emergency settings. World Vision International together with Columbia University is conducting a series of studies to investigate the effectiveness of CFSs in va

rious humanitarian contexts in order to document evidence of the positive effects they have in relation to child wellbeing and protection, to identify good practice in their design and implementation and to develop improved monitoring and evaluation approaches for CFSs. The case studies have so far all been focused on refugee settings and while internally displaced populations (IDPs) share many of the circumstances and challenges of refugees it was decided that CFSs operating in IDP settings warrant a particular investigation in order to assess their relevance and effectiveness in promoting child protection and psychosocial wellbeing. This report thus presents the findings from an IDP focused study on CFS effectiveness in three camps near Goma, eastern Democratic Republic of Congo (DRC).

racterize and assess the risk factors for SARS-CoV-2 infection in health workers exposed to COVID-19 patients.
Health workers with confirmed COVID-19 will be recruited as cases and other health workers in the same health care setting without infection will be recruited as controls (incidence density sampling).
Secondary objectives are similar to the cohort study.

Outbreak Investigation, Response and Control – Module 8. Integrated Disease Surveillance Project: Training Manual for State & District Surveillance Officers
Integrated Disease Surveillance Project (IDSP)
Ministry of Health and Family Welfare, Government of India
(2005)
C2
The document “Outbreak Investigation, Response and Control – Module 8” is a training module from the Integrated Disease Surveillance Project (IDSP) designed to guide health officials in investigating and managing disease outbreaks. It explains
...
the basic principles and steps of outbreak investigation, including detecting unusual increases in disease cases, confirming diagnoses, collecting and analyzing epidemiological data, and identifying the source and mode of transmission. The module also describes appropriate control and prevention measures, emphasizes timely reporting and coordination within the surveillance system, and aims to strengthen the capacity of public health workers to effectively respond to infectious disease outbreaks at the district and state levels.

a disease outbreak. It is mainly intended for epidemiologists and public health professionals, particularly participants in the ECDC Fellowship Programme. The guide explains the purpose of outbreak investigation reports and describes the recommended structure and content of such reports, including sections such as background, objectives, methods, results, and conclusions. It also outlines how to present epidemiological, laboratory, and environmental findings, interpret the results, and formulate public health recommendations. Overall, the document aims to standardize outbreak reporting, improve the quality and clarity of reports, and ensure that investigation findings can effectively support public health decision-making and future outbreak prevention.
