Ebola outbreak in Guinea, 2021: Clinical care of patients with Ebola virus disease.

Background: Experience from the Zaire Ebolavirus epidemic in the eastern Democratic Republic of the Congo (2018-2020) demonstrates that early initiation of essential critical care and administration of Zaire Ebolavirus specific monoclonal antibodies may be associated with improved outcomes among patients with Ebola virus disease (EVD).

Objectives: This series describes 13 EVD patients and 276 patients with suspected EVD treated during a Zaire Ebolavirus outbreak in Guinea in 2021.

Method: Patients with confirmed or suspected EVD were treated in two Ebola treatment centres (ETC) in the region of N'zérékoré.

Ebola Virus Infection Associated with Transmission from Survivors.

Ebola virus (EBOV) can persist in immunologically protected body sites in survivors of Ebola virus disease, creating the potential to initiate new chains of transmission. From the outbreak in West Africa during 2014-2016, we identified 13 possible events of viral persistence-derived transmission of EBOV (VPDTe) and applied predefined criteria to classify transmission events based on the strength of evidence for VPDTe and source and route of transmission. For 8 events, a recipient case was identified; possible source cases were identified for 5 of these 8.

Infection prevention and control training and capacity building during the Ebola epidemic in Guinea.

Background: During the 2014-2016 Ebola epidemic in West Africa, a key epidemiological feature was disease transmission within healthcare facilities, indicating a need for infection prevention and control (IPC) training and support.

Methods: IPC training was provided to frontline healthcare workers (HCW) in healthcare facilities that were not Ebola treatment units, as well as to IPC trainers and IPC supervisors placed in healthcare facilities. Trainings included both didactic and hands-on components, and were assessed using pre-tests, post-tests and practical evaluations.

Depressive symptoms among survivors of Ebola virus disease in Conakry (Guinea): preliminary results of the PostEboGui cohort.

Background: The 2013-2016 West African Ebola outbreak infected 28,616 people and caused 11,310 deaths by 11 May 2016, across six countries. The outbreak has also resulted in the largest number of EVD survivors in history-over 17,000. Guinea was declared Ebola-free on 1 June 2016.

Characteristics of the musculoskeletal symptoms observed among survivors of Ebola virus disease in the Postebogui cohort in Guinea.

Objective: Previous studies show that arthralgia is the most common symptom experienced by Ebola virus disease (EVD) survivors. Nevertheless, specific analyses of rheumatological sequelea are still lacking.

Methods: The Postebogui study is a prospective, multicentre cohort aiming to evaluate the long-term outcomes of EVD survivors infected during the 2014-15 outbreak in Guinea.

Dynamics of Ebola RNA Persistence in Semen: A Report From the Postebogui Cohort in Guinea.

This study modeled the presence of Ebola virus RNA in the semen of male Ebola survivors participating in the Postebogui study in Guinea. The median time of reverse-transcription polymerase chain reaction negativity was 46.4 days after symptom onset (95% confidence interval, 11-82.

Multidisciplinary assessment of post-Ebola sequelae in Guinea (Postebogui): an observational cohort study.

Background: The high number of survivors from the 2013-16 west African outbreak of Ebola virus disease (EVD) has raised several new issues: long-term clinical complications, psychosocial consequences, risks of EVD reactivation, and secondary transmission due to viral persistence in body fluids. We aimed to assess long-term clinical, psychosocial, and viral outcomes in EVD survivors in Guinea.

Methods: In this multidisciplinary observational cohort study, we recruited patients aged 1 year or more in four sites in Guinea (Donka National Hospital, Conakry; Macenta Prefectoral Hospital, Macenta; N'zérékoré Regional Hospital, N'zérékoré; and Forécariah Prefectoral Hospital, Forécariah) following discharge from any Ebola treatment centre in Guinea.

Ocular Complications in Survivors of the Ebola Outbreak in Guinea.

Purpose: The Ebola outbreak of 2013-2016 severely affected West Africa and resulted in 2544 deaths and 1270 survivors in Guinea, the country where it began. This Ebola virus was the Zaire strain of the virus family Filoviridae. In this outbreak the case fatality rate was about 67%.

New Evidence of Long-lasting Persistence of Ebola Virus Genetic Material in Semen of Survivors.

Ninety-eight semen specimens were obtained for Ebola virus (EBOV) RNA screening from 68 men in Guinea during the convalescent phase of EBOV infection. Ten samples from 8 men were positive for EBOV up to 9 months after onset of the disease, with decreasing trends in the proportion of positive samples and the level of viral RNA. Safe sex practices should be observed after discharge from treatment centers.

High survival rates and associated factors among ebola virus disease patients hospitalized at donka national hospital, conakry, Guinea.

Background: Anecdotal reports suggesting that survival rates among hospitalized patients with Ebola virus disease in Guinea are higher than the 29.2% rate observed in the current epidemic in West Africa.

Methods: Survival after symptom onset was determined using Kaplan Meier survival methods among patients with confirmed Ebola virus disease treated in Conakry, Guinea from March 25, 2014, to August 5, 2014.

Clinical predictors of mortality in patients with Ebola virus disease.

In an observational cohort study including 89 Ebola patients, predictive factors of death were analyzed. The crude mortality rate was 43.8%.

Clinical presentation of patients with Ebola virus disease in Conakry, Guinea.

Background: In March 2014, the World Health Organization was notified of an outbreak of Zaire ebolavirus in a remote area of Guinea. The outbreak then spread to the capital, Conakry, and to neighboring countries and has subsequently become the largest epidemic of Ebola virus disease (EVD) to date.

Methods: From March 25 to April 26, 2014, we performed a study of all patients with laboratory-confirmed EVD in Conakry.
