The SARS-CoV-2 (COVID-19) pandemic has had a tremendous impact on the functionality of health systems and world affairs. We assessed knowledge, attitudes, and practices (KAPs) of healthcare workers (HCWs) in the Democratic Republic of the Congo (DRC). This was a cross-sectional study conducted in 23 referral hospitals located in three towns of the DRC (Lubumbashi, Kamina, Mbuji-Mayi). In total, 613 HCWs were surveyed using the World Health Organization’s (WHO’s) “Exposure Risk Assessment in the Context of COVID-19” questionnaire. Participants included medical doctors (27.2%) and other categories of HCWs (72.8%). The mean age was 40.3 ± 11.7 years. Over 80% (range: 83–96%) of respondents had sufficient knowledge on each of the three domains: COVID-19 symptoms, disease transmission, and patient care approach. However, attitudes and practices scores were relatively low. Only 27.7% of HCWs were willing to receive a COVID-19 vaccine when it is available, whereas 55% of HCWs complied with good practices; 49.4% wore masks consistently and, surprisingly, only 54.9% used personal protective equipment (PPE) consistently at work and during contact with patients. Knowledge level was positively associated with the use of social media as a primary source of COVID-19-related information and the category of residence, with HCWs from towns already affected by the COVID-19 epidemic being more likely to have positive attitudes (adjusted OR, 1.64; 95%CI, 1.32–2.20) and comply with good practices (aOR, 2.79; 95%CI, 1.93-4.06). This study showed that most Congolese HCWs had sufficient knowledge on COVID-19, whereas the majority did not comply with consistent PPE use. The government of the DRC should urgently take major steps in capacity building for HCWs in outbreak preparedness and supplying hospitals with PPE.

Background and Aim. Environmental and occupational exposure to high dust levels are known to be associated with lung function impairment. We assessed the ambient air quality in the working environment and the respiratory health of female stone quarry workers in Lubumbashi, Democratic Republic of Congo (DRC) in a context of severe economic, security, and health crises. Methods. This was a case-control study conducted in three stone quarry sites. Participants were 256 dust-exposed female stone quarry workers matched to 256 unexposed female office workers and market tax collectors (N = 512). They each answered a structured respiratory health questionnaire and underwent physical examination and a lung function test with the use of a spirometer and peak flow meter. Quality of ambient air in the working environment was assessed by means of a BRAMC air quality monitor (BR-AIR-329). Results. Results showed that exposed women did not use any personal protective equipment (PPE); in quarry sites, abnormally high levels of PM2.5 (205 ± 13.2 μg/m3 vs. 31.3 ± 10.3 μg/m3 in control sites; p < 0.001) and volatile organic compounds (VOC, 2.2 ± 0.2 μg/m3 vs. 0.5 ± 0.3 μg/m3, respectively; p < 0.01) were found. Furthermore, respiratory complaints were more common among exposed women (32.4% vs. 3.5% in controls; p < 0.01), who had abnormal chest auscultation and reduced lung capacity than controls (mean PEFR: 344.8 ± 2.26 and 405 ± 67.7 L/s, respectively; p < 0.001 Conclusion. Findings from this study show that in the midst of severe crises in the DRC, women stone quarry workers are exposed to abnormally high levels of respiratory hazards, which contribute to impaired lung function. There is a need to regulate quarry work and improve the working conditions in quarry sites in the DRC.

Background An Ebola disaster, the deadliest in the history of Ebola in the Democratic Republic of Congo (DRC), is unfolding in North Kivu and Ituri provinces. An interdisciplinary research team investigated the impact of the Ebolavirus disease (EVD) outbreak on vital health services delivery under the coordination of DRC National Vaccination Program, Ministry of Health. We report on the impact of the ongoing Eastern Congo EVD outbreak on routine child immunization in the EVD-affected in North Kivu province, DRC. Methods This was a retrospective longitudinal study consisting in a time-trend analysis that was conducted in 40 public health facilities that organize routine child immunization in four of the 34 ‘Health Zones’ of the North Kivu province, namely Beni, Butembo, Katwa and Mabalako. Data were collected during two distinct 3-month periods: the “pre-Ebola period” (1 May through July 2018) and the “Ebola period” (1 August through October 2018), to compare the vaccination trends. Mean number of vaccine doses administered in pre-Ebola and Ebola periods were compared (unpaired t test). Results Compared to the “pre-Ebola period”, overall monthly mean vaccines uptake dropped during the “Ebola period”: BCG (157.1 ± 150.3 vs. 227.5 ± 138.4; p<0.0001), Oral polio (OPV: 505.1 ± 474.6 vs. 631.3 ± 353.9; p<0.001), Measles vaccine (147.6 ± 126.7 vs. 184.7 ± 102.5; p<0.001), pneumoccocal vaccine (PCV13: 445.8 ± 395.5 vs. 554.3 ± 299.8; p<0.001) and inactivated polio vaccine (IPV: 183.9 ± 141 vs. 153.9 ± 146.6; p<0.01). Furthermore, when considering the trend in child immunization in each of the four Health Zones during ‘Ebola period’, vaccine uptake shrank considerably in most health zones, whereas a complete disruption of vaccine delivery was observed in Mabalako health zone where the epicenter of this outbreak is located. Conclusion The ongoing Ebola outbreak has a negative impact on child health services, routine vaccination in particular. Supplementary immunization coupled with the strengthening of routine child vaccination services should be implemented to address gaps in immunity among children in affected provinces and reduce the risk of other infectious diseases outbreaks.
