Ijara district in Kenya was one of the hotspots of Rift Valley fever (RVF) during the 2006/2007 outbreak, which led to human and animal deaths causing major economic losses. The main constraint for the control and prevention of RVF is inadequate knowledge of the risk factors for its occurrence and maintenance. This study was aimed at understanding the perceived risk factors and risk pathways of RVF in cattle in Ijara to enable the development of improved community-based disease surveillance, prediction, control and prevention. A cross-sectional study was carried out from September 2012 to June 2013. Thirty-one key informant interviews were conducted with relevant stakeholders to determine the local pastoralists’ understanding of risk factors and risk pathways of RVF in cattle in Ijara district. All the key informants perceived the presence of high numbers of mosquitoes and large numbers of cattle to be the most important risk factors contributing to the occurrence of RVF in cattle in Ijara.
Rift Valley fever (RVF) is an important neglected, emerging, mosquito-borne disease with severe negative impact on human and animal health. Mosquitoes in the Aedes genus have been considered as the reservoir, as well as vectors, since their transovarially infected eggs withstand desiccation and larvae hatch when in contact with water. However, different mosquito species serve as epizootic/epidemic vectors of RVF, creating a complex epidemiologic pattern in East Africa. The recent RVF outbreaks in Somalia (2006–2007), Kenya (2006–2007), Tanzania (2007), and Sudan (2007–2008) showed extension to districts, which were not involved before.
These outbreaks also demonstrated the changing epidemiology of the disease from being originally associated with livestock, to a seemingly highly virulent form infecting humans and causing considerably high-fatality rates. The amount of rainfall is considered to be the main factor initiating RVF outbreaks. The interaction between rainfall and local environment,
Climate change is projected to lead to warmer temperatures, especially in southern Africa, where the warming is predicted to be 2°C higher than the global increase. Given the high burden of disease already associated with environmental factors in this region, this temperature increase may lead to grave challenges for human health and quality of life. HIV/AIDS, poverty, food and water insecurity together with inequality and unemployment will further complicate the manner in which we will need to address the challenges of a changing climate.
The health impacts are direct, such as increased temperatures leading to heat exhaustion, and indirect, such as likely increases in infectious diseases from contaminated water and changes in the distribution and/or magnitude of vector-borne diseases. The most effective measures for adapting to climate change to ensure healthy populations are to implement basic public health systems and services.
The training manual has two parts. Part 1 covers ethical issues in research and surveillance, such as conflicts that might arise between the common good and individual autonomy, ethics oversight and publication ethics. Part 2 covers patient care, including triage, standards of care and the professional duties of healthcare workers in emergencies.The teaching resources are modular, comprising seven core competences and 26 learning objectives, each with a dedicated module.
The modules are based on various types of instruction and activities (e.g. case study, lecture, group discussion, role play, video) to meet the learning objective. Slide sets were prepared for the lectures under each learning objective and summary slide sets for each core competence. At the end of the manual, you will find a compilation of all of the case studies used throughout the manual.
This working paper reports on a study to identify epidemic control priorities among 15 communities in Monrovia and Montserrado County, Liberia. Data were collected in September 2014 on the following topics: prevention, surveillance, care-giving, community-based treatment and support, networking/hotlines/calling response teams and referrals, management of corpses, quarantine and isolation, orphans, memorialization, and the need for community-based training and education.
The study also reviewed issues of fear and stigma towards Ebola victims and survivors, and support for those who have been affected by Ebola. The findings provide several models that can inform international and governmental support for community-based management of the current Ebola outbreak.
Of the 46 countries in the World Health Organization (WHO) African region (AFRO), 43 are implementing Integrated Disease Surveillance and Response (IDSR) guidelines to improve their abilities to detect, confirm, and respond to high priority communicable and non-communicable diseases. IDSR provides a framework for strengthening the surveillance, response, and laboratory core capacities required by the revised International Health Regulations (IHR, 2005)]. In turn, IHR obligations can serve as a driving force to sustain national commitments to IDSR strategies.
The ability to report potential public health events of international concern according to IHR (2005) relies on early warning systems founded in national surveillance capacities. Public health events reported through IDSR to the WHO Emergency Management System in Africa illustrate the growing capacities in African countries to detect, assess, and report infectious and noninfectious threats to public health. The IHR (2005) provide an opportunity to continue strengthening national IDSR systems so they can characterise outbreaks and respond to public health events in the region.
