Background: The 1994 Genocide against the Tutsi was a major traumatic event affecting nearly all Rwandans. Significant psychological sequels continue to occur in the population 25 years after, with a high prevalence of posttraumatic stress disorder (PTSD) found in women. Three groups are typically designated with regard to the Genocide against the Tutsi: those who were targeted and categorized as genocide “survivors,” those who were in the country during the genocide and were the “non-targeted” group, and those who were outside of the country, referred to as the “1959 returnees.” Each group experienced various traumatic events during and in the aftermath of the genocide. Offspring of the designated groups, currently exhibit symptoms of PTSD disregarding of being born in the years following the genocide. A number of studies have described the prevalence of PTSD in the general adult population. There is a lack of research comparing the prevalence of PTSD in women and their offspring among these three target groups, therefore, this study aimed to bridge the gap. Methods: We conducted a comparative cross-sectional study with a sample of 432 mothers and 432 children in three categories: genocide survivors, in country non-targeted and 1959 returnees. Participant ages for children were between 14 to 22 years and for mothers, between the ages of 32 to 87 years. The UCLA-PTSD DSM-5, PTSD Check list-5 and Life events Checklist-5 were translated from English to Kinyarwanda and were used to assess exposure to trauma and the prevalence of PTSD symptoms in Rwandan mothers and their offspring. Results: Key Results yield a PTSD rate of 18.8, 6.2, 5.2% within survivors, in country non-targeted, and returnees respectively with an average PTSD rate of 43.8% for parents, and 16.5% for offspring. Conclusion: PTSD among the mothers’ groups and their offspring have been found, specifically in the offspring of genocide survivors. Considering these adolescents were not born at the time of the 1994 Genocide against the Tutsi, the results suggest future studies should explore the precipitating factors contributing to the PTSD symptoms within this specific group.

The African region was predicted to have worse COVID-19 infection and death rates due to challenging health systems and social determinants of health. However, in the 10 months after its first case, Rwanda recorded 10316 cases and 133 COVID-19-related deaths translating to a case fatality rate (CFR) of 1.3%, which raised the question: why does Rwanda have a low COVID-19 CFR? Here we analysed COVID-19 data and explored possible explanations to better understand the disease burden in the context of Rwanda’s infection control strategies.We investigated whether the age distribution plays a role in the observed low CFR in Rwanda by comparing the expected number of deaths for 10-year age bands based on the CFR reported in other countries with the observed number of deaths for each age group. We found that the age-specific CFRs in Rwanda are similar to or, in some older age groups, slightly higher than those in other countries, suggesting that the lower population level CFR reflects the younger age structure in Rwanda, rather than a lower risk of death conditional on age. We also accounted for Rwanda’s comprehensive SARS-CoV-2 testing strategies and reliable documentation of COVID-19-related deaths and deduced that these measures may have allowed them to likely identify more asymptomatic or mild cases than other countries and reduced their reported CFR.Overall, the observed low COVID-19 deaths in Rwanda is likely influenced by the combination of effective infection control strategies, reliable identification of cases and reporting of deaths, and the population’s young age structure.

Introduction: Precision medicine (PM) or personalized medicine is an innovative approach that aims to tailor disease prevention and treatment to consider the differences in people’s genes, environments, and lifestyles. Although many efforts have been made to accelerate the universal adoption of PM, several challenges need to be addressed in order to advance PM in Africa. Therefore, our study aimed to establish baseline data on the knowledge and perceptions of the implementation of PM in the Rwandan healthcare setting. Method: A descriptive qualitative study was conducted in five hospitals offering diagnostics and oncology services to cancer patients in Rwanda. To understand the existing policies regarding PM implementation in the country, two additional institutions were surveyed: the Ministry of Health (MOH), which creates and sets policies for the overall vision of the health sector, and the Rwanda Biomedical Center (RBC), which coordinates the implementation of health sector policies in the country. The researchers conducted 32 key informant interviews and assessed the functionality of available PM equipment in the 5 selected health facilities. The data were thematically categorized and analyzed. Results: The study revealed that PM is perceived as a complex and expensive program by most health managers and health providers. The most cited challenges to implementing PM included the following: the lack of policies and guidelines; the lack of supportive infrastructures and limited suppliers of required equipment and laboratory consumables; financial constraints; cultural, behavioral, and religious beliefs; and limited trained, motivated, and specialized healthcare providers. Regarding access to health services for cancer treatment, patients with health insurance pay 10% of their medical costs, which is still too expensive for Rwandans. Conclusion: The study participants highlighted the importance of PM to enhance healthcare delivery if the identified barriers are addressed. For instance, Rwandan health sector leadership might consider the creation of specialized oncology centers in all or some referral hospitals with all the necessary genomic equipment and trained staff to serve the needs of the country and implement a PM program.

The ongoing outbreak of Marburg virus disease (MVD) in Rwanda marks the third largest historically, though it has exhibited the lowest fatality rate. Genomic analysis has identified a lineage with limited internal diversity most closely related to a genome sequence from a sporadic case sampled in 2014 in Uganda, though the lineages have diverged from a common ancestor that was circulating for decades in the animal reservoir. Notably, the data also provide evidence that the outbreak resulted from a single zoonotic transmission event with limited human-to-human transmission, rather than multiple independent zoonotic transmission events. The Rwandan MVD outbreak prompted a thorough investigation that included contact tracing, clinical assessment, travel history, sequencing, and serology testing, to trace the virus’s origin. Results of investigations linked the index case to a mining cave inhabited by Rousettus aegyptiacus (the Egyptian fruit bat), where three individuals tested seropositive for IgG and IgM, further supporting the zoonotic origin of the outbreak through human-animal interactions.
