Abstract Background Somali Red Crescent Society (SRCS), supported by Norwegian Red Cross, has implemented community-based surveillance (CBS) in Somaliland. This methodology aims to reduce the high risk of epidemics by strengthening early warning and response from and at community level, particularly where there is a weak public health surveillance system. CBS is implemented through SRCS community volunteers, who report signals from the community via SMS to the software platform Nyss. This paper presents key findings from the CBS programme evaluation. Methods A retrospective observational mixed-methods approach to evaluate the CBS programme was conducted, using routine CBS data from 2021 for Awdal and Togdheer regions and qualitative interviews with stakeholders’ representatives. Results The usefulness of the CBS programme in preventing, detecting, and responding to disease outbreaks was acknowledged by the stakeholders’ representatives. 83% of the signals in Awdal region matched a Community Case Definition (CCD) and were escalated to the Ministry of Health and Development (MoHD)). For Togdheer region, 97% were escalated. Verification of signals by supervisors and escalation to the authorities was done timely.Alert outcome and response action was not well recorded, therefore there is limited evidence on sensitivity. The programme was shown to be simple and can be flexibly adjusted for new diseases and changing CCDs.Stakeholders appreciated being engaged, the good collaboration, their participation throughout the implementation and expressed high acceptance of the programme. Conclusion CBS can support early warning and response for a variety of public health risks. Improved documentation for alert outcomes could help to better evaluate the sensitivity of CBS. A participatory approach is vital to achieve successful community volunteer engagement. Software tools, such as the Nyss platform, can be useful to support effective and efficient CBS implementation.

Epidemic preparedness, the ability to prevent, respond and control epidemic outbreaks, has remained a neglected concept and policy practice for many years, detached from health policy and health systems planning. The cornerstone of epidemic preparedness is the preparedness of public health services, which consists of effective early warning systems and control of cross-border spread of communicable diseases, the ability to design and implement focused and proportional non pharmaceutical interventions, the effective epidemiological surveillance and transparent management of epidemiological data, the scientific consistency and accountability of public health authorities. The COVID-19 pandemic has revealed, both on a national and international level, the significant gaps and structural deficiencies of all the above mentioned elements of public health (services') preparedness. Current and expected future public health threats leave no room for complacency; public health services need to be urgently reorganized through integration into comprehensive public primary healthcare systems and strengthened through increased public investment in financial resources, infrastructure and healthcare workers.

Mpox (formerly known as monkeypox) was declared a Public Health Emergency of International Concern (PHEIC) by the World Health Organization on 23rd July 2022, however cases of the disease have been detected in Nigeria since the 1970s and more recently since it began spreading in more urban areas of the country from 2017 onward. Nigeria has a strong track record of epidemic preparedness and response, spearheaded by the Nigeria Centre for Disease Control. Despite being somewhat separate architectures on paper, epidemic response (in particular, integrated disease surveillance and response) relies on a foundation of primary health care, which is inadequately funded not only in Nigeria, but globally. Situating mpox response within this wider landscape, we draw on ethnographic research from September 2022–March 2023 in southwestern Nigeria on lived experiences of mpox and mpox response, focusing on the perspectives of frontline health workers and community-based suspected or confirmed mpox cases. We aimed to understand how prioritization and resource constraints shape mpox response at a local level, including effects on the everyday work of frontline health workers in public health and clinical care who are left to "make do." We analyze their experiences interfacing with two intersecting infrastructures, community-based surveillance and primary health care. Health workers' improvisation and "repair work," which we detail, enables the surveillance system to function in some capacity. However, health workers must regularly contend with competing priorities and routine care that may be sidelined during an outbreak or epidemic. We argue that this reveals the limitations of a global health security agenda as it materializes at a local level and the need for strengthening primary health care for longer-term sustainability. • This ethnographic study examined mpox response in southwestern Nigeria. • Epidemic response infrastructure depends on a strong primary health care system. • Primary health care is underfunded in Nigeria. • Frontline health workers engage in repair and improvisation. • This is unsustainable without further primary health system strengthening.

Epidemic prone diseases threaten public health security. These include diseases such as cholera, meningitis, and hemorrhagic fevers, especially Lassa fever for which Nigeria reports considerable morbidity and mortality annually. Interestingly, where emergency epidemic preparedness plans are in place, timely detection of outbreaks is followed by a prompt and appropriate response. Furthermore, due to the nature of spread of Lassa fever in an outbreak setting, there is the need for health-care workers to be familiar with the emerging epidemic management framework that has worked in other settings for effective preparedness and response. This paper, therefore, discussed the principles of epidemic management using an emergency operating center model, review the epidemiology of Lassa fever in Nigeria, and provide guidance on what is expected to be done in preparing for epidemic of the disease at the health facilities, local and state government levels in line with the Integrated Disease Surveillance and Response strategy.

Background: The continuing circulation of MERS in the Middle East makes the international dissemination of the disease a permanent threat. To inform risk assessment, we investigated the spatiotemporal pattern of MERS global dissemination and looked for factors explaining the heterogeneity observed in transmission events following importation.Methods: We reviewed imported MERS cases worldwide up to July 2015. We modelled importations in time based on air travel combined with incidence in Middle East. We used the detailed history of MERS case management after importation (time to hospitalization and isolation, number of hospitals visited,…) in logistic regression to identify risk factors for secondary transmission. We assessed changes in time to hospitalization and isolation in relation to collective and public health attention to the epidemic, measured by three indicators (Google Trends, ProMED-mail, Disease Outbreak News).Results: Modelled importation events were found to reproduce both the temporal and geographical structure of those observed - the Pearson correlation coefficient between predicted and observed monthly time series was large (r = 0.78, p < 10(-4)). The risk of secondary transmission following importation increased with the time to case isolation or death (OR = 1.7 p = 0.04) and more precisely with the duration of hospitalization (OR = 1.7, p = 0.02). The average daily number of secondary cases was 0.02 [0.0,0.12] in the community and 0.20 [0.03,9.0] in the hospital. Time from hospitalisation to isolation decreased in periods of high public health attention (2.33 ± 0.34 vs. 6.44 ± 0.97 days during baseline attention).Conclusions: Countries at risk of importation should focus their resources on strict infection control measures for the management of potential cases in healthcare settings and on prompt MERS cases identification. Individual and collective awareness are key to substantially improve such preparedness. [ABSTRACT FROM AUTHOR]
