ABSTRACT
BACKGROUND: Multiple studies have described increased risk of severe coronavirus disease (COVID-19) among pregnant women compared to nonpregnant women. The risk in middle-income countries where the distributions of age groups and preexisting conditions may differ is less known. OBJECTIVES: To determine whether pregnant women with SARS-CoV-2 infection are at increased risk for severe COVID-19 compared to nonpregnant women in Colombia. METHODS: We analysed national surveillance data from Colombia, of women aged 15-44 years with laboratory-confirmed infection with SARS-CoV-2 by molecular or antigen testing, from 6 March 2020 to 12 December 2020. An enhanced follow-up of pregnant women with COVID-19 was established to monitor pregnancy and birth outcomes. RESULTS: Of 371,363 women aged 15-44 years with laboratory-confirmed SARS-CoV-2 infection, 1.5% (n = 5614) were reported as pregnant; among those, 2610 (46.5%) were considered a complete pregnancy for reporting purposes at the time of analysis. Hospitalisation (23.9%) and death (1.3%) occurred more frequently among pregnant symptomatic women compared to nonpregnant symptomatic women (2.9% and 0.3%, respectively). Compared to nonpregnant symptomatic women, pregnant symptomatic women were at increased risk of hospitalisation (adjusted risk ratio [RR] 2.19, 95% confidence interval [CI] 2.07, 2.32) and death (RR 1.82, 95% CI 1.60, 2.07), after adjusting for age, type of health insurance and presence of certain underlying medical conditions. Among complete pregnancies, 55 (2.1%) were pregnancy losses, 72 (2.8%) resulted in term low birthweight infants and 375 (14.4%) were preterm deliveries. CONCLUSIONS: Although pregnant women were infrequently reported with laboratory-confirmed SARS-CoV-2 infection, pregnant symptomatic women with COVID-19 were at increased risk for hospitalisation and death compared to nonpregnant symptomatic women. Almost all infections we reported on were third-trimester infections; ongoing follow-up is needed to determine pregnancy outcomes among women infected earlier in pregnancy. Healthcare providers should counsel pregnant women about preventive measures to protect from SARS-CoV-2 infection and when to seek care.

BACKGROUND: This prospective cohort investigation analyzed the long-term functional and neurologic outcomes of patients with Zika virus-associated Guillain-Barré syndrome (GBS) in Barranquilla, Colombia. METHODS: Thirty-four Zika virus-associated GBS cases were assessed a median of 17 months following acute GBS illness. We assessed demographics, results of Overall Disability Sum Scores (ODSS), Hughes Disability Score (HDS), Zung Depression Scale (ZDS), and Health Related Quality of Life (HRQL) questionnaires; and compared outcomes indices with a normative sample of neighborhood-selected control subjects in Barranquilla without GBS. RESULTS: Median age at time of acute neurologic onset was 49 years (range, 10-80); 17 (50%) were male. No deaths occurred. At long-term follow-up, 25 (73%) patients had a HDS 0-1, indicating complete / near complete recovery. Among the group, HDS (mean 1.4, range 0-4), ODSS (mean 1.9, range 0-9) and ZDS score (mean 34.4, range 20-56) indicated mild / moderate ongoing disability. Adjusting for age and sex, Zika virus-associated GBS cases were similar to a population comparison group (n = 368) in Barranquilla without GBS in terms of prevalence of physical or mental health complaints, though GBS patients were more likely to have an ODSS of ≥ 1 (OR 8.8, 95% CI 3.2-24.5) and to suffer from moderate / moderate-severe depression (OR 3.89, 95% CI 1.23-11.17) than the comparison group. CONCLUSIONS: Long-term outcomes of Zika virus-associated GBS are consistent with those associated with other antecedent antigenic stimuli in terms of mortality and ongoing long-term morbidity, as published in the literature. Persons with Zika virus-associated GBS more frequently reported disability and depression after approximately one year compared with those without GBS.

OBJECTIVES: To determine OPV coverage impact of the 2001 national immunization day in different geographic regions and its association with the Unsatisified Basic Needs Index (NBI), forced displacement and armed conflict. METHODS: This is an analytical ecological study of multiple groups using multilevel observation units such as region, department, province and municipality. A bivariate analysis with difference between proportions between paired samples (McNemar test), estimation of OR, lineal regression and relative risk determination (Morgenstern) was carried out. In addition, protected and susceptible populations in each observation unit were compared. RESULTS: The OPV3 coverage increase between October and December, 2001, was 15 to 19% (p<0.05) and the final coverage was 78-84%. The provincial analysis demonstrated a 25.8% of total population with OPV3 coverage greater than 95%. An increase of 4 to 7 departments and 281 to 328 cities with at least 95% coverage (p<0.05) was observed. The risk of having incomplete immunization schedules decreased in armed conflict zones, remained stable in areas with high NBI and increased in areas with a high proportion of displaced families. The booster goal of the OPV had reached a median of 61%. CONCLUSIONS: The national immunization day diminished immunization access barriers for children under 5 years. The analysis of different geographic units controls the effect of the unknown population denominators. The ecological studies improved routine data analysis.
