Baseline knowledge and attitudes on COVID-19 among hotels' staff: A cross-sectional study in Kigali, Rwanda.

BACKGROUND: The World Health Organization declared coronavirus disease 2019 (COVID-19) as a global pandemic on the 11th of March, 2020. Hotels and other public establishments have been associated with higher transmission rates. Sensitisation of staff and strengthening of Infection Prevention and Control (IPC) practices in such settings are important interventions. This study assessed the baseline knowledge and attitudes on COVID-19 among hotels' representatives in Kigali, Rwanda. METHODS: A cross-sectional study was conducted among hotels' staff in Kigali in July 2020. A structured questionnaire was self-administered to 104 participants. Baseline knowledge and attitudes were assessed using a number of pre-test questions and mean scores were used to dichotomise the participants' responses as satisfactory or unsatisfactory. RESULTS: All of the 104 hotels' staff completed the self-administered questionnaires. Sixty-seven percent (n = 70) were male and 58% (n = 60) were aged between 30 and 44 years. The satisfactory rate of correct answers was 63%±2.4 (n = 66) on knowledge and 68%±1.7 (n = 71) on attitudes evaluation. Participants with University education were more likely to have satisfactory knowledge (AOR: 2.6, 95% C.I: 1.07-6.58) than those with secondary education or less. The staff working in the front-office (AOR: 0.05; 95% CI 0.01-0.54) and housekeeping (AOR: 0.09; 95% C.I: 0.01-0.87) were less likely to have satisfactory attitudes than those working in the administration. CONCLUSIONS: Hotels' staff based in the capital of Rwanda have shown satisfactory knowledge and attitudes regarding appropriate IPC practices for preventing the COVID-19 transmission. Educational interventions are needed to improve their knowledge and attitudes for better prevention in this setting.

Case Definitions Used During the First 6 Months of the 10th Ebola Virus Disease Outbreak in the Democratic Republic of the Congo - Four Neighboring Countries, August 2018-February 2019.

On August 1, 2018, the Democratic Republic of the Congo (DRC) declared its 10th Ebola virus disease (Ebola) outbreak in an area with a high volume of cross-border population movement to and from neighboring countries. The World Health Organization (WHO) designated Rwanda, South Sudan, and Uganda as the highest priority countries for Ebola preparedness because of the high risk for cross-border spread from DRC (1). Countries might base their disease case definitions on global standards; however, historical context and perceived risk often affect why countries modify and adapt definitions over time, moving toward or away from regional harmonization. Discordance in case definitions among countries might reduce the effectiveness of cross-border initiatives during outbreaks with high risk for regional spread. CDC worked with the ministries of health (MOHs) in DRC, Rwanda, South Sudan, and Uganda to collect MOH-approved Ebola case definitions used during the first 6 months of the outbreak to assess concordance (i.e., commonality in category case definitions) among countries. Changes in MOH-approved Ebola case definitions were analyzed, referencing the WHO standard case definition, and concordance among the four countries for Ebola case categories (i.e., community alert, suspected, probable, confirmed, and case contact) was assessed at three dates (2). The number of country-level revisions ranged from two to four, with all countries revising Ebola definitions by February 2019 after a December 2018 peak in incidence in DRC. Case definition complexity increased over time; all countries included more criteria per category than the WHO standard definition did, except for the "case contact" and "confirmed" categories. Low case definition concordance and lack of awareness of regional differences by national-level health officials could reduce effectiveness of cross-border communication and collaboration. Working toward regional harmonization or considering systematic approaches to addressing country-level differences might increase efficiency in cross-border information sharing.

Hepatitis B virus and HIV co-infection among pregnant women in Rwanda.

BACKGROUND: Hepatitis B virus (HBV) affects people worldwide but the local burden especially in pregnant women and their new born babies is unknown. In Rwanda HIV-infected individuals who are also infected with HBV are supposed to be initiated on ART immediately. HBV is easily transmitted from mother to child during delivery. We sought to estimate the prevalence of chronic HBV infection among pregnant women attending ante-natal clinic (ANC) in Rwanda and to determine factors associated with HBV and HIV co-infection. METHODS: This study used a cross-sectional survey, targeting pregnant women in sentinel sites. Pregnant women were tested for hepatitis B surface antigen (HBsAg) and HIV infection. A series of tests were done to ensure high sensitivity. Multivariable logistic regression was used to identify independent predictors of HBV-HIV co-infection among those collected during ANC sentinel surveillance, these included: age, marital status, education level, occupation, residence, pregnancy and syphilis infection. RESULTS: The prevalence of HBsAg among 13,121 pregnant women was 3.7% (95% CI: 3.4-4.0%) and was similar among different socio-demographic characteristics that were assessed. The proportion of HIV-infection among HBsAg-positive pregnant women was 4.1% [95% CI: 2.5-6.3%]. The prevalence of HBV-HIV co-infection was higher among women aged 15-24 years compared to those women aged 25-49 years [aOR = 6.9 (95% CI: 1.8-27.0)]. Women residing in urban areas seemed having HBV-HIV co-infection compared with women residing in rural areas [aOR = 4.3 (95% CI: 1.2-16.4)]. Women with more than two pregnancies were potentially having the co-infection compared to those with two or less (aOR = 6.9 (95% CI: 1.7-27.8). Women with RPR-positive test were seemed associated with HBV-HIV co-infection (aOR = 24.9 (95% CI: 5.0-122.9). CONCLUSION: Chronic HBV infection is a public health problem among pregnant women in Rwanda. Understanding that HBV-HIV co-infection may be more prominent in younger women from urban residences will help inform and strengthen HBV prevention and treatment programmes among HIV-infected pregnant women, which is crucial to this population.

Hepatitis C virus and HIV co-infection among pregnant women in Rwanda.

BACKGROUND: Hepatitis C virus (HCV) infection is a pandemic causing disease; more than 185 million people are infected worldwide. An HCV antibody (Ab) prevalence of 6.0% was estimated in Central African countries. The study aimed at providing HCV prevalence estimates among pregnant women in Rwanda. METHODS: HCV surveillance through antibody screening test among pregnant women attending antenatal clinics was performed in 30 HIV sentinel surveillance sites in Rwanda. RESULTS: Among 12,903 pregnant women tested at antenatal clinics, 335 (2.6% [95% Confidence Interval 2.32-2.87]) tested positive for HCV Ab. The prevalence of HCV Ab in women aged 25-49 years was 2.8% compared to 2.4% in women aged 15-24 years (aOR = 1.3; [1.05-1.59]); This proportion was 2.7% [2.37-2.94] in pregnant women in engaged in non-salaried employment compared to 1.2% [0.24-2.14] in those engaged in salaried employment (aOR = 3.2; [1.60-6.58]). The proportion of HCV Ab-positive co-infected with HIV was estimated at 3.9% (13 cases). Women in urban residence were more likely to be associated with HCV-infection (OR = 1.3; 95%CI [1.0-1.6]) compared to those living in rural setting. CONCLUSION: HCV is a public health problem in pregnant women in Rwanda. Few pregnant women were co-infected with HCV and HIV. Living in urban setting was more likely to associate pregnant women with HCV infection.

Ten-year trends of syphilis in sero-surveillance of pregnant women in Rwanda and correlates of syphilis-HIV co-infection.

Syphilis can be transmitted by pregnant women to their children and is a public health problem in Africa. A cross-sectional survey was conducted in 24 antenatal clinics from 2002 to 2003 and increased to 30 sites from 2005 to 2011. Participants were tested for syphilis and HIV. Multi-variate logistic regression was performed to identify risks associated with syphilis and its co-infection with HIV. Results showed that syphilis decreased from 3.8% in 2002 to 2.0% in 2011. Syphilis in the HIV-infected participants increased from 6.0% in 2002 to 10.8% in 2011, but decreased from 3.7% to 1.7% in the HIV-negative participants. In 2011, syphilis in urban participants was 2.7% and 1.4% in rural ones. HIV-infected participants screened positive for syphilis more frequently in both rural (aOR = 3.64 [95% CI: 1.56%-8.51%]) and urban areas (aOR = 7.26 [95% CI: 5.04%-10.46%]). Older participants (25-49 years) residing in urban areas (aOR = 0.43[95% CI: 0.32%-0.58%]) and women with secondary or high education (aOR = 0.35[95% CI: 0.20%-0.62%]) were less likely to screen positive for syphilis. HIV-syphilis co-infection was more likely in women residing in urban areas (aOR = 8.32[95% CI: 3.54%-19.56%]), but less likely in women with secondary/high education (aOR = 0.11[95% CI: 0.01%-0.77%]). In conclusion, syphilis increased in HIV-positive pregnant women, but decreased in HIV-negative women. Positive HIV status and young age were associated risks for syphilis. HIV-syphilis co-infection was associated with a lower level of education and urban residence.

HIV surveillance in Rwanda: readiness assessment to transition from antenatal care-based to prevention of mother-to-child transmission program-based HIV surveillance.

BACKGROUND: In 2013, the World Health Organization (WHO) recommended that for efficiency and ethical considerations, transitioning from antenatal clinic-based surveillance to prevention of mother-to-child transmission (PMTCT)-based routine data should be investigated. An assessment of the readiness for this transition was carried out in Rwanda in 2011 and 2013. METHODS: This assessment applied the WHO recommended method. Individual HIV rapid testing at site was compared to antenatal surveillance results at all existing 30 sites, involving 13 292 women. In addition, PMTCT HIV testing quality assurance and PMTCT routine data quality were assessed at 27 out of the 30 sites. RESULTS: All sentinel sites provided PMTCT services and had a high uptake of HIV testing (more than 90%). At all sites, PMTCT data were recorded in longitudinal and standardized antenatal clinic registers. Twenty-six out of 27 sites had HIV result completeness above 90%. A positive percentage agreement of 97.5% and negative percentage agreement of 99.9% were observed between routine PMTCT and sero-surveillance HIV test results. Of 27 sites, 25 scored more than 80% in all phases of HIV testing quality assurance. CONCLUSIONS: According to WHO standards, Rwanda antenatal care HIV sero-surveillance is ready to transition to PMTCT-based sero-surveillance.

Estimation of the size of the female sex worker population in Rwanda using three different methods.

HIV prevalence is disproportionately high among female sex workers compared to the general population. Many African countries lack useful data on the size of female sex worker populations to inform national HIV programmes. A female sex worker size estimation exercise using three different venue-based methodologies was conducted among female sex workers in all provinces of Rwanda in August 2010. The female sex worker national population size was estimated using capture-recapture and enumeration methods, and the multiplier method was used to estimate the size of the female sex worker population in Kigali. A structured questionnaire was also used to supplement the data. The estimated number of female sex workers by the capture-recapture method was 3205 (95% confidence interval: 2998-3412). The female sex worker size was estimated at 3348 using the enumeration method. In Kigali, the female sex worker size was estimated at 2253 (95% confidence interval: 1916-2524) using the multiplier method. Nearly 80% of all female sex workers in Rwanda were found to be based in the capital, Kigali. This study provided a first-time estimate of the female sex worker population size in Rwanda using capture-recapture, enumeration, and multiplier methods. The capture-recapture and enumeration methods provided similar estimates of female sex worker in Rwanda. Combination of such size estimation methods is feasible and productive in low-resource settings and should be considered vital to inform national HIV programmes.

Bridging the accountability divide: male circumcision planning in Rwanda as a case study in how to merge divergent operational planning approaches.

When voluntary medical male circumcision (MC) was confirmed as an effective tool for HIV prevention in sub-Saharan Africa in 2007, many public health policy makers and practitioners were eager to implement the intervention. How to roll out the tool as part of comprehensive strategy however was less clear. At the time, very little was known about the capacity of health systems to scale delivery of the new intervention. Today, nearly all countries prioritized for the intervention are far behind their targets. To contribute to the discourse on why this is, we develop a historical analysis of medical MC planning in sub-Saharan Africa using our own experience of this process in Rwanda. We compare our previously unpublished feasibility analysis from 2008 with international research published in 2009, which suggested how Rwanda could reduce HIV incidence through a rapid MC intervention, and Rwanda's eventual 2010 official operational plan. We trace how, in the face of uncertainty, operational plans avoided discussing the details of feasibility and focused instead on defining optimal circumcision capacity needed to achieve country level target reductions in HIV incidence. We show a distinct gap between the targets set in the official operational plan and what we determined was feasible in 2008. With actual data from the ground now available, we show our old feasibility models more closely approximate circumcision delivery rates to date. With an eye toward the future of long-term policy planning, we discuss the mechanics of how accountability gaps like this occur in global health policy making and how practitioners can better create achievable operational targets.
