Abstract
BACKGROUND In 2021, an Ebola virus disease (EVD) outbreak was declared in Guinea, linked to persistent virus from the 2014-2016 West Africa Epidemic. This paper analyzes factors associated with contact tracing reliability (defined as completion of a 21-day daily follow-up) during the 2021 outbreak, and transitively, provides recommendations for enhancing contact tracing reliability in future. METHODS We conducted a descriptive and analytical cross-sectional study using multivariate regression analysis of contact tracing data from 1071 EVD contacts of 23 EVD cases (16 confirmed and 7 probable). RESULTS Findings revealed statistically significant factors affecting contact tracing reliability. Unmarried contacts were 12.76× more likely to miss follow-up than those married (OR = 12.76; 95% CI [3.39-48.05]; p < 0.001). Rural-dwelling contacts had 99% lower odds of being missed during the 21-day follow-up, compared to those living in urban areas (OR = 0.01; 95% CI [0.00-0.02]; p < 0.01). Contacts who did not receive food donations were 3× more likely to be missed (OR = 3.09; 95% CI [1.68-5.65]; p < 0.001) compared to those who received them. Contacts in health areas with a single team were 8× more likely to be missed (OR = 8.16; 95% CI [5.57-11.96]; p < 0.01) than those in health areas with two or more teams (OR = 1.00; 95% CI [1.68-5.65]; p < 0.001). Unvaccinated contacts were 30.1× more likely to be missed compared to vaccinated contacts (OR = 30.1; 95% CI [5.12-176.83]; p < 0.001). CONCLUSION Findings suggest that contact tracing reliability can be significantly influenced by various demographic and organizational factors. Considering and understanding these factors-and where possible addressing them-may be crucial when designing and implementing contact tracing strategies during future outbreaks in low-resource settings.

Abstract
BACKGROUND Strategy to mitigate various Ebola virus disease (EVD) outbreaks are focusing on Infection Prevention and Control (IPC) capacity building, supportive supervision and IPC supply donation. This study was conducted to assess the impact of a Pay for Performance Strategy (PPS) in improving IPC performance in healthcare facilities (HF) in context of the 2018-2019 Nord Kivu/ Democratic Republic of the Congo EVD outbreak. METHODS A quasi-experimental study was conducted analysing the impact of a PPS on the IPC performance. HF were selected following the inclusion criteria upon informed consent from the facility manager and the National Department of Health. Initial and process assessment of IPC performance was conducted by integrating response teams using a validated IPC assessment tool for HF. A bundle of interventions was then implemented in the different HF including training of health workers, donation of IPC kits, supportive supervision during the implementation of IPC activities, and monetary reward. IPC practices in HF were assessment every two weeks during the intervention period to measure the impact. The IPC assessment tool had 34 questions aggregated in 8 different thematic areas: triage and isolation capacity, IPC committee in HF, hand hygiene, PPE, decontamination and sterilization, linen management, hospital environment and Waste management. Data were analysed using descriptive statistics and analytical approaches according to assumptions. R software (version 4.0.3) was used for all the analyses and a p-value of 0.05 was considered as the threshold for statistically significant results. RESULTS Among 69 HF involved in this study, 48 were private facilities and 21 state facilities. The median baseline IPC score was 44% (IQR: 21-65%); this IPC median score reached respectively after 2, 4, 6 and 8 weeks 68% (IQR: 59-76%), 79% (71-84%), 76% (68-85%) and 79% (74-85%). The improvement of IPC score was statistically significative. Spearman's rank-order correlation revealed the associated between proportion of trained HW and IPC score performance after 8 weeks of interventions (rs = .280, p-value = 0.02). CONCLUSION Pay for Performance Strategy was proved effective in improving healthcare facilities capacity in infection prevention and control practice in context of 2018 EVD outbreak in Nord Kivu. However, the strategy for long-term sustainability of IPC needs further provision. More studies are warranted on the HW and patients' perceptions toward IPC program implementation in context of Nord Kivu Province.

Abstract
In this case report, we describe a clinical presentation and therapeutic history of a unique case diagnosed with Lassa fever and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a 23-year-old man from Yomou prefecture in southeast Guinea identified with suspected Ebola Virus Disease (EVD) in the midst of an ongoing outbreak of that disease in the same region. On May 3, 2021, he was admitted to the Nzérékoré Epidemic disease treatment center where his clinical condition deteriorated significantly. Laboratory testing performed on the same day reveals a negative EVD polymerase chain reaction (PCR). Three days later, the patient was tested positive for SARS-CoV-2 and Lassa fever by reverse transcriptase PCR (RT-PCR) assays. Laboratory examination also indicated severe hematological and biochemical deteriorations in the patient. This case substantiates the need for systematic differential diagnosis during epidemic-prone disease outbreaks to better manage severely unwell patients.

Abstract
The new coronavirus pandemic (COVID-19) is the main global health crisis of our time and the greatest threat we have faced in this century. According to the National Health Security Agency (ANSS), which is the national body responsible for managing epidemics and pandemics, 1927 cases of COVID-19 were confirmed, 11 deaths with more than 4000 contact subjects. The objective of this study was to assess the impact of the COVID-19 pandemic on the activities of the cardiology department of the Ignace Deen National Hospital at the Conakry University Hospital. This was a descriptive retrospective study from January 2020 to April 2020, focusing on consultation and hospitalisation activities in the cardiology department of Ignace Deen National Hospital at Conakry University Hospital. The study consisted of assessing the impact of the pandemic on patient use of the service during the first weeks of the pandemic. We recorded the frequency of consultations and hospitalisations from March to April 2020, which we compared to the frequency of consultations and hospitalisations in January and February 2020. During this study from March to April 2020, we identified 130 patients in consultation against 450 patients for the two months preceding the official declaration of the pandemic in Guinea, a drop of 71.1% (320 patients). The same remark was made in hospitalisation with a drop of 75% (35 patients against 140 for the two months preceding the pandemic). At the start of the COVID-19 pandemic in Guinea, it is clear that there has been a rapid and significant drop in the effective use of the cardiology service.

Abstract
During public health crises such as the recent outbreaks of Ebola virus disease in West Africa, breakdowns in public health systems can lead to epidemics of vaccine-preventable diseases. We report here on an outbreak of measles in the prefecture of Lola, Guinea, which started in January 2015.
