Emergency response to a cluster of suspected foodborne botulism in Abuja, Nigeria: challenges with diagnosis and treatment in a resource-poor setting
Food-borne botulism is a rare, acute and potentiallyfatal neurologic disorder that results from ingestionof food contaminated by botulinum toxin releasedfrom the anaerobic, spore-forming, gram-positivebacterium Clostridium botulinum. We reported anunusual cluster of botulism outbreak with high casefatality affecting a family following ingestion ofhome-made fish. A suspected outbreak of botulismaffecting three patients in a family of six wasreported to the Nigeria Centre for Disease Control.A rapid response team investigated by line-listing allthe family members, interviewed extended familymembers, caregivers, clinicians, and nurses tocollect socio-demographic and clinicoepidemiological information using a semistructured questionnaires. We collected blood frompatients and food samples and locally made drinkfrom the family home for laboratory testing. Allfamily members ingested the same home-madefood within the 48hrs before onset of symptoms inthe index case. The clinical presentation of the threeaffected cases (AR=50.0%) was consistent withbotulinum poisoning. Two of the affected cases died(CFR=66.7%) within 48hrs of admission, beforeantitoxin was made available. The third case had amilder presentation and survived, afteradministration of appropriate antitoxin. Theremaining three children developed no symptoms.None of the samples cultured Clostridiumbotulinum. The blood samples were negative formouse lethality test. Our report describes thechallenges of diagnosis and management of rareemerging infectious disease outbreaks in resourceconstrained settings
Severe Acute Respiratory Syndrome Coronavirus 2 Infection and Pregnancy in Sub-Saharan Africa: A 6-Country Retrospective Cohort Analysis
BACKGROUND: Few data are available on COVID-19 outcomes among pregnant women in sub-Saharan Africa (SSA), where high-risk comorbidities are prevalent. We investigated the impact of pregnancy on SARS-CoV-2 infection and of SARS-CoV-2 infection on pregnancy to generate evidence for health policy and clinical practice. METHODS: We conducted a 6-country retrospective cohort study among hospitalized women of childbearing age between 1 March 2020 and 31 March 2021. Exposures were (1) pregnancy and (2) a positive SARS-CoV-2 RT-PCR test. The primary outcome for both analyses was intensive care unit (ICU) admission. Secondary outcomes included supplemental oxygen requirement, mechanical ventilation, adverse birth outcomes, and in-hospital mortality. We used log-binomial regression to estimate the effect between pregnancy and SARS-CoV-2 infection. Factors associated with mortality were evaluated using competing-risk proportional subdistribution hazards models. RESULTS: Our analyses included 1315 hospitalized women: 510 pregnant women with SARS-CoV-2, 403 nonpregnant women with SARS-CoV-2, and 402 pregnant women without SARS-CoV-2 infection. Among women with SARS-CoV-2 infection, pregnancy was associated with increased risk for ICU admission (adjusted risk ratio [aRR]: 2.38; 95% CI: 1.42-4.01), oxygen supplementation (aRR: 1.86; 95% CI: 1.44-2.42), and hazard of in-hospital death (adjusted sub-hazard ratio [aSHR]: 2.00; 95% CI: 1.08-3.70). Among pregnant women, SARS-CoV-2 infection increased the risk of ICU admission (aRR: 2.0; 95% CI: 1.20-3.35), oxygen supplementation (aRR: 1.57; 95% CI: 1.17-2.11), and hazard of in-hospital death (aSHR: 5.03; 95% CI: 1.79-14.13). CONCLUSIONS: Among hospitalized women in SSA, both SARS-CoV-2 infection and pregnancy independently increased risks of ICU admission, oxygen supplementation, and death. These data support international recommendations to prioritize COVID-19 vaccination among pregnant women
