Pneumonia: A Challenging Health Concern with the Climate Change

Pneumonia is still a global health concern with high mortality rate, mainly among children under 5 years and adults over 65 years. In addition to pathogen virulence, immunoevasion capacity, and drug resistance ability, risk factors for the patient include aging, comorbidities, malnutrition, and all causes affecting the immune system. The extent to which environmental disorders affect the respiratory health is established for chronic diseases such as asthma, COPD, and cardiovascular diseases, but less is known about the underlying mechanisms of their impact on infectious diseases of the respiratory system. This chapter aims to recall the epidemiology, diagnosis, and treatment of pneumonia, with a focus on the impact of climate change and related risk factors on acute low tract respiratory infections

Impact of COVID-19 on admission due to diarrhea to the emergency department of the largest specialized Pediatric Hospital, Kinshasa, the Democratic Republic of the Congo: A retrospective analysis: Impact de la COVID-19 sur les admissions dues à la diarrhée aux urgences du plus grand hôpital pédiatrique spécialisé, Kinshasa, RDC : une analyse rétrospective

Context and objective. The COVID-19’s lockdown effect on pediatric healthcare utilization has been demonstrated. However, little is known about this impact on the burden of diarrheal diseases among children in sub-Saharan Africa. This study aimed at studying the impact of the COVID-19 pandemic on admissions due to diarrhea into the largest specialized Pediatric Hospital in the city of Kinshasa. Methods. A retrospective study was conducted on diarrhea cases admitted into the emergency department of the Kalembe-Lembe Pediatric Hospital between January 1st and July 31st of 2019 and 2020. Variables were compared during the pandemic’s lockdown period in 2020 to the equivalent period in 2019. Results. Overall, 422 medical records were examined. A 45% drop in diarrhea cases was observed in the pediatric emergency department between the study periods in 2019 and 2020. Daily admissions were significantly higher in 2019 than in 2020 (p < 0.001). The majority of patients were admitted with moderate dehydration in 2019 than in 2020 (p < 0.001) but an increase in proportion of patients with mild and severe dehydration was observed in 2020 than in 2019 (p < 0.001). The hospitalization rate was significantly higher in 2019 than in 2020 (p < 0.001). Conclusions; The COVID-19’s restrictions led to a substantial decrease in admissions due to diarrhea among children to the pediatric emergency department. Public health interventions are needed to promote an ambulatory healthcare system during future crises. Contexte et objectif. L’effet de confinement dû à la COVID-19 sur l’utilisation des soins pédiatriques a été démontré sous d’autres cieux. Cependant, on en sait peu concernant cet impact sur le fardeau des maladies diarrhéiques chez les enfants en Afrique subsaharienne. Cette étude visait à rechercher l’impact de la pandémie à COVID-19 sur les admissions dues à la diarrhée dans un hôpital pédiatrique. Méthodes. Etude documentaire des cas de diarrhées recensés, au service des urgences de l’hôpital pédiatrique de Kalembe-Lembe, entre les 1er janvier et 31 juillet 2019 et 2020. Les variables ont été comparées, entre la période du confinement de la pandémie en 2020 et la période équivalente en 2019. Résultats. Au total 442 dossiers médicaux ont été colligés. Une baisse de 45 % d’admissions des cas de diarrhée a été observée, aux urgences pédiatriques pendant le confinement. Les admissions quotidiennes étaient significativement plus élevées en 2019 qu'en 2020 (p <0,001). La majorité des patients ont été admis avec une déshydratation modérée en 2019 qu'en 2020 (p<0,001) mais une augmentation de la proportion de patients avec une déshydratation légère et sévère a été observée en 2020 par rapport à 2019 (p <0,001). Le taux d'hospitalisation était significativement plus élevé en 2019 qu'en 2020 (p <0,001). Conclusion. Les restrictions dues à la COVID-19 ont conduit à une diminution substantielle des admissions dues à la diarrhée chez les enfants aux urgences pédiatriques. Des interventions de santé publique sont nécessaires pour promouvoir un système de santé ambulatoire lors d'une telle crise dans un proche avenir

Modalités et voies préférentielles de propagation géographique du choléra à partir des zones endémiques de l'est de la République démocratique du Congo

Cholera is endemic along the Great Lakes Region, in eastern Democratic Republic of the Congo (DRC). From these endemic areas, also under perpetual conflicts, outbreaks spread to other areas. However, the main routes of propagation remain unclear. This research aimed to explore the modalities and likely main routes of geographic spread of cholera from endemic areas in eastern DRC. We used historical reconstruction of major outbreak expansions of cholera since its introduction in eastern DRC, maps of distribution and spatiotemporal cluster detection analyses of cholera data from passive surveillance (2000-2017) to describe the spread dynamics of cholera from eastern DRC. Four modalities of geographic spread and their likely main routes from the source areas of epidemics to other areas were identified: in endemic eastern provinces, and in non-endemic provinces of eastern, central and western DRC. Using non-parametric statistics, we found that the higher the number of conflict events reported in eastern DRC, the greater the geographic spread of cholera across the country. The present study revealed that the dynamics of the spread of cholera follow a fairly well-defined spatial logic and can therefore be predicted

Gestion du coronavirus par la Chine : "Il y a transparence et transparence"

À l'heure où le nombre de décès dus au coronavirus a dépassé le cap des 250, "il apparaît dès maintenant que la gestion interne s'est faite avec une légèreté peu admissible dans ce type de crise où chaque instant compte", écrivent trois scientifiques.

Vaccination dropout rates among children aged 12-23 months in Democratic Republic of the Congo: a cross-sectional study.

[en] BACKGROUND: Overall, 1.8 million children fail to receive the 3-dose series for diphtheria, tetanus and pertussis each year in the Democratic Republic of the Congo (DRC). Currently, an emergency plan targeting 9 provinces including Kinshasa, the capital of the DRC, is launched to reinforce routine immunization. Mont Ngafula II was the only health district that experienced high vaccination dropout rates for nearly five consecutive years. This study aimed to identify factors predicting high immunization dropout rates among children aged 12-23 months in the Mont Ngafula II health district. METHODS: A cross-sectional household survey was conducted among 418 children in June-July 2019 using a two-stage sampling design. Socio-demographic and perception data were collected through a structured interviewer-administered questionnaire. The distribution of 2017-2018 immunization coverage and dropout rate was extracted from the local health district authority and mapped. Logistic random effects regression models were used to identify predictors of high vaccination dropout rates. RESULTS: Of the 14 health areas in the Mont Ngafula II health district, four reported high vaccine coverage, only one recorded low vaccine coverage, and three reported both low vaccine coverage and high dropout rate. In the final multivariate logistic random effects regression model, the predictors of immunization dropout among children aged 12-23 months were: living in rural areas, unavailability of seats, non-compliance with the order of arrival during vaccination in health facilities, and lack of a reminder system on days before the scheduled vaccination. CONCLUSIONS: Our results advocate for prioritizing targeted interventions and programs to strengthen interpersonal communication between immunization service providers and users during vaccination in health facilities and to implement an SMS reminder system on days before the scheduled vaccination

La propagation du choléra dans l'ouest de la République démocratique du Congo n'est pas unidirectionnelle d'Est en Ouest : une analyse spatio-temporelle, 1973-2018

Background: Cholera outbreaks in western Democratic Republic of the Congo (DRC) are thought to be primarily the result of westward spread of cases from the Great Lakes Region. However, other patterns of spatial spread in this part of the country should not be excluded. The aim of this study was to explore alternative routes of spatial spread in western DRC. Methods: A literature review was conducted to reconstruct major outbreak expansions of cholera in western DRC since its introduction in 1973. We also collected data on cholera cases reported at the health zone (HZ) scale by the national surveillance system during 2000-2018. Based on data from routine disease surveillance, we identified two subperiods (week 45, 2012 – week 42, 2013 and week 40, 2017 – week 52, 2018) for which the retrospective space-time permutation scan statistic was implemented to detect spatiotemporal clusters of cholera cases and then to infer the spread patterns in western DRC other than that described in the literature. Results: Beyond westward and cross-border spread in the West Congo Basin from the Great Lakes Region, other dynamics of cholera epidemic propagation were observed from neighboring countries, such as Angola, to non-endemic provinces of southwestern DRC. Space-time clustering analyses sequentially detected clusters of cholera cases from southwestern DRC to the northern provinces, demonstrating a downstream-to-upstream spread along the Congo River. Conclusions: The spread of cholera in western DRC is not one-sided. There are other patterns of spatial spread, including a propagation from downstream to upstream areas along the Congo River, to be considered as preferential trajectories of cholera in western DRC
