Seven years after the declaration of the first epidemic of Ebola virus disease in Guinea, the country faced a new outbreak-between 14 February and 19 June 2021-near the epicentre of the previous epidemic 1,2 . Here we use next-generation sequencing to generate complete or near-complete genomes of Zaire ebolavirus from samples obtained from 12 different patients. These genomes form a well-supported phylogenetic cluster with genomes from the previous outbreak, which indicates that the new outbreak was not the result of a new spillover event from an animal reservoir. The 2021 lineage shows considerably lower divergence than would be expected during sustained human-to-human transmission, which suggests a persistent infection with reduced replication or a period of latency. The resurgence of Zaire ebolavirus from humans five years after the end of the previous outbreak of Ebola virus disease reinforces the need for long-term medical and social care for patients who survive the disease, to reduce the risk of re-emergence and to prevent further stigmatization.At least 30 outbreaks of Ebola virus disease (EVD) have been identified since the late 1970s, the most severe of which affected Guinea, Sierra Leone and Liberia from December 2013 to June 2016 1,2 . Guinea experienced a new outbreak of EVD in 2021, which started in Gouéké-a town about 200 km away from the epicentre of the 2013-2016 outbreak. The probable index case was a 51-year-old nurse, an assistant of the hospital midwife in Gouéké. On 21 January 2021, she was admitted to hospital in Gouéké suffering from headache, asthenia, nausea, anorexia, vertigo and abdominal pain. She was diagnosed with malaria and salmonellosis and was released two days later. Feeling ill again once at home, she attended a private clinic in Nzérékoré (40 km away) and visited a traditional healer, but died three days later. In the week after her death, her husband-as well as other family members who attended her funeral-fell ill, and four of them died. They were reported as the first suspect cases by the national epidemic alert system on 11 February. On 12 February, blood was taken from two suspect cases admitted to

Anxiety and depression continue to be significant comorbidities for people with human immunodeficiency virus (HIV) infection. The aim of this study was to determine the prevalence of anxiety and depression disorder among HIV patients at Conakry, Guinea. In this cross-sectional study, we described socio-demographic, clinical and psychosocial data related to anxiety and depression in 160 HIV patients of the University Teaching Hospital, Conakry, Guinea. The Hospital Anxiety and Depression Scale (HADS) was used for measuring depression and anxiety in the prior month. The HADS score of ⩾8 was used to identify possible cases of depression and anxiety. Multivariate logistic regression analyses were performed to identify factors associated with symptoms of anxiety and depression. The prevalence of comorbid depression and anxiety among HIV patients was 8.1% and the prevalence of anxiety and depressive symptoms among HIV-infected patients was 13.8% and 16.9%, respectively. Multivariate analysis showed that individuals having BMI ⩽ 18 (AOR = 3.62, 95% confidence interval (CI) 1.37–9.57) and who did not receive antiretroviral treatment (AOR = 18.93, 95% CI 1.88–188.81) were significantly more likely to have depressive symptoms. Similarly, having age <40 years (AOR = 2.81, 95% CI 1.04–7.58) was also significantly associated with anxiety. Prevalence of symptoms of anxiety and depression was high in these HIV patients. This suggests a need for training on the screening and management of anxiety and depression among HIV patients.

In the current Ebola virus disease (EVD) outbreak, health care workers (HCWs) are on the frontline of the response. The study aimed to report on the knowledge, attitudes and practices of Conakry HCWs. A cross-sectional survey was done among HCWs from the two national hospitals and at the communal hospitals in Conakry, using a standardized questionnaire. Demographic, knowledge, attitudes and practices data of the respondents were recorded and analyzed. Respondents (n = 525) were mainly physicians (43.0%) or nurses (36.8%). Over 90% of HCWs cited the three major clinical signs of EVD. Only 68% knew the correct concentration of Javel water that is advised for hand washing. This was known by 69.4% of nurses, 59.0% of residents, 69.5% of physicians, 100% of pharmacists and 60.9% of midwifes (P = 0.35). The EVD transmission risk in the ward was estimated as probable for 70.6% and very probable for 24.0% of HCWs. Eighty-four percent of all respondents estimated their knowledge on EVD insufficient and 97.1% reported that they either need specific training on EVD or enhance their knowledge. This study underlines the low level of knowledge, attitude and perceptions regarding EVD prevention despite the high incidence and mortality of this disease.
