Estimating the number of probable new SARS-CoV-2 infections among tested subjects from the number of confirmed cases.

Objectives: In most African countries, confirmed COVID-19 case counts underestimate the number of new SARS-CoV-2 infection cases. We propose a multiplying factor to approximate the number of biologically probable new infections from the number of confirmed cases.

Methods: Each of the first thousand suspect (or alert) cases recorded in South Kivu (DRC) between 29 March and 29 November 2020 underwent a RT-PCR test and an IgM and IgG serology.

[Mauvais contrôle des facteurs de risque cardiovasculaire modifiables chez les patients congolais en phase aiguë et séquellaire d'un accident vasculaire cérébral : Une étude transversale].

Purpose: To assess the level of the control of the cardiovascular risk factors in patients with a history of stroke in the Democratic Republic of the Congo.

Methods: The level of the control of arterial hypertension, diabetes mellitus, and dyslipidemias was analyzed in two hundred and seventy-four (274) patients followed for stroke.

Results: Among 188 patients with a prior diagnosis of arterial hypertension, only 100 (53.

Prevalence and incidence of arterial hypertension and its risk factors in the 7,525 person-years Congolese adult population between 2012 and 2019 : results of the Bukavu observational study.

Background: In the Sub-Saharan African region, data on Arterial Hypertension (AHT) from longitudinal studies are scattered.This work analyzes the prevalence and incidence of AHT and its associated factors in an open cohort of Congolese adults in South Kivu.

Methods: Between 2012 and 2019, 2,633 subjects aged ≥ 15 years were monitored for at least 3 years.

Concurrent Heavy Metal Exposures and Idiopathic Dilated Cardiomyopathy: A Case-Control Study from the Katanga Mining Area of the Democratic Republic of Congo.

Blood and/or urine levels of 27 heavy metals were determined by ICPMS in 41 patients with dilated cardiomyopathy (DCM) and 29 presumably healthy subjects from the Katanga Copperbelt (KC), in the Democratic Republic of Congo (DRC). After adjusting for age, gender, education level, and renal function, DCM probability was almost maximal for blood concentrations above 0.75 and 150 µg/dL for arsenic and copper, respectively.

[Seroprevalence of SARS-CoV-2 antibodies among travellers and workers screened at the Saint Luc Clinic in Bukavu, a city in eastern Democratic Republic of the Congo, from May to August 2020].

Introduction: SARS-CoV-2 serology tests could play a crucial role in estimating the prevalence of COVID-19. The purpose of this study was to estimate the prevalence of COVID-19 among travellers and workers in Bukavu, a city in eastern Democratic Republic of the Congo.

Methods: between May and August 2020, the Cellex qSARS-CoV-2 IgG/IgM Rapid Test (Cellex, Inc.
