RESUMO

Common mental disorders such as depression and anxiety are prevalent globally, and rates are especially high in New York City (NYC) since the COVID-19 pandemic. Neighborhood social and physical environments have been found to influence mental health. We investigated the impact of neighborhood social cohesion and neighborhood rodent sightings (as an indicator of neighborhood cleanliness) on nonspecific serious psychological distress (NSPD) status using 2020 NYC Community Health Survey data from 8781 NYC residents. Multivariable logistic regression was used to evaluate the relationships among social cohesion, rodent sightings, and NSPD adjusted for confounders and complex sampling and weighted to the NYC population. Effect measure modification of rodent sightings on the effect of social cohesion on NSPD was evaluated on the multiplicative scale by adding the interaction term to the multivariable model and, if significant, stratifying on the effect modifier, and on the additive scale using the relative excess risk due to interaction (RERI). Social cohesion was found to decrease the odds of NSPD, and rodent sightings were found to increase the odds of NSPD. We found significant evidence of effect measure modification on the multiplicative scale. In the stratified models, there was a protective effect of social cohesion against NSPD among those not reporting rodent sightings, but no effect among those reporting rodent sightings. Our findings suggest that both neighborhood social cohesion and rodent sightings impact the mental health of New Yorkers and that rodent infestations may diminish the benefit of neighborhood social cohesion.

RESUMO

In a population-based survey of adults in New York City, we assessed positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) tests (including via exclusive at-home testing) and possible cases among untested respondents. An estimated 27.4% (95% confidence interval [CI]: 22.8%-32.0%) or 1.8 million adults (95% CI: 1.6-2.1 million) had SARS-CoV-2 infection between 1 January and 16 March 2022.

RESUMO

BACKGROUND: We estimated the prevalence of long COVID and impact on daily living among a representative sample of adults in the United States. METHODS: We conducted a population-representative survey, 30 June-2 July 2022, of a random sample of 3042 US adults aged 18 years or older and weighted to the 2020 US population. Using questions developed by the UK's Office of National Statistics, we estimated the prevalence of long COVID, by sociodemographics, adjusting for gender and age. RESULTS: An estimated 7.3% (95% confidence interval: 6.1-8.5%) of all respondents reported long COVID, corresponding to approximately 18 828 696 adults. One-quarter (25.3% [18.2-32.4%]) of respondents with long COVID reported their day-to-day activities were impacted "a lot" and 28.9% had severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection more than 12 months ago. The prevalence of long COVID was higher among respondents who were female (adjusted prevalence ratio [aPR]: 1.84 [1.40-2.42]), had comorbidities (aPR: 1.55 [1.19-2.00]), or were not (vs were) boosted (aPR: 1.67 [1.19-2.34]) or not vaccinated (vs boosted) (aPR: 1.41 [1.05-1.91]). CONCLUSIONS: We observed a high burden of long COVID, substantial variability in prevalence of SARS-CoV-2, and risk factors unique from SARS-CoV-2 risk, suggesting areas for future research. Population-based surveys are an important surveillance tool and supplement to ongoing efforts to monitor long COVID.

RESUMO

Due to changes in SARS-CoV-2 testing practices, passive case-based surveillance may be an increasingly unreliable indicator for monitoring the burden of SARS-CoV-2, especially during surges. We conducted a cross-sectional survey of a population-representative sample of 3042 U.S. adults between June 30 and July 2, 2022, during the Omicron BA.4/BA.5 surge. Respondents were asked about SARS-CoV-2 testing and outcomes, COVID-like symptoms, contact with cases, and experience with prolonged COVID-19 symptoms following prior infection. We estimated the weighted age and sex-standardized SARS-CoV-2 prevalence, during the 14-day period preceding the interview. We estimated age and gender adjusted prevalence ratios (aPR) for current SARS-CoV-2 infection using a log-binomial regression model. An estimated 17.3% (95% CI 14.9, 19.8) of respondents had SARS-CoV-2 infection during the two-week study period-equating to 44 million cases as compared to 1.8 million per the CDC during the same time period. SARS-CoV-2 prevalence was higher among those 18-24 years old (aPR 2.2, 95% CI 1.8, 2.7) and among non-Hispanic Black (aPR 1.7, 95% CI 1.4,2.2) and Hispanic adults (aPR 2.4, 95% CI 2.0, 2.9). SARS-CoV-2 prevalence was also higher among those with lower income (aPR 1.9, 95% CI 1.5, 2.3), lower education (aPR 3.7 95% CI 3.0,4.7), and those with comorbidities (aPR 1.6, 95% CI 1.4, 2.0). An estimated 21.5% (95% CI 18.2, 24.7) of respondents with a SARS-CoV-2 infection >4 weeks prior reported long COVID symptoms. The inequitable distribution of SARS-CoV-2 prevalence during the BA.4/BA.5 surge will likely drive inequities in the future burden of long COVID.

RESUMO

Objectives. To measure vaccine uptake and intentions among New York City (NYC) parents of children aged 5 to 11 years following emergency use authorization. Methods. We conducted a survey of 2506 NYC parents of children aged 5 to 11 years. We used survey weights to generate prevalence estimates of vaccine uptake and intentions. Multivariable Poisson regression models generated adjusted prevalence ratios (APRs) of vaccine hesitancy, defined as parents who reported being not very likely or not at all likely to vaccinate their children, or unsure about whether to do so. Results. Overall, 11.9% of NYC parents reported that their child was vaccinated; 51.0% were very or somewhat likely to vaccinate; 8.0% were not sure; 29.1% were not very likely or not at all likely to vaccinate their child. Among vaccine-hesitant parents, 89.9% reported safety concerns and 77.8% had concerns about effectiveness. In multivariable models, more vaccine hesitancy was expressed by non-Hispanic Black parents than by non-Hispanic White parents (APR = 1.41; 95% confidence interval [CI] = 1.17, 1.72) and by parents who were not themselves vaccinated than by parents who were vaccinated (APR = 1.53; 95% CI = 1.32, 1.77). Conclusions. In a survey conducted after authorization of COVID-19 vaccines for children aged 5 to 11 years, significant hesitancy among parents was observed.

RESUMO

The COVID-19 pandemic has decreased uptake of pediatric preventive care, including immunizations. We estimate the prevalence of missed pediatric routine medical visits and vaccinations over the first year of the COVID-19 pandemic. We conducted a cross-sectional online survey of 2074 US parents of children ≤12 years in March 2021 to measure the proportion of children who missed pediatric care and vaccinations over the first 12 months of the COVID-19 pandemic. Poisson regression models were fitted to estimate adjusted prevalence ratios (aPR). All analyses were weighted to represent the target population. Overall, 41.3% (95%CI 38.3-43.8) of parents reported their youngest child missed a routine medical visit due to the COVID-19 pandemic. Missed care was more common among children ≥2 years compared to <2 years (aPR 1.82; 95%CI 1.47-2.26) and Hispanics compared to non-Hispanic Whites (aPR 1.31; 95%CI 1.14-1.51). A third of parents (33.1%; 95%CI 30.7-35.5) reported their child had missed a vaccination. Compared to the 2019-20 flu season, pediatric influenza vaccination decreased in 2020-21 (51.3% vs. 62.2%; p < 0.0001). A high proportion of US children ≤12 years missed routine pediatric care during the COVID-19 pandemic. Catch-up efforts are needed to ensure continuity of preventive care for all children.

RESUMO

BACKGROUND: Pregnant and breastfeeding adolescents and young women living with HIV (AYWLH) have lower retention in prevention of mother-to-child transmission (PMTCT) services compared to older women. METHODS: We evaluated a differentiated service model for pregnant and postnatal AYWLH at seven health facilities in western Kenya aimed at improving retention in antiretroviral treatment (ART) services. All pregnant AYWLH < 25 years presenting for antenatal care (ANC) were invited to participate in group ANC visits including self-care and peer-led support sessions conducted by health facility nurses per national guidelines. ART register data were used to assess loss to follow-up (LTFU) among newly-enrolled pregnant adolescent (< 20 years) and young women (20-24 years) living with HIV starting ART in the pre-period (January-December 2016) and post-period (during implementation; December 2017-January 2019). Poisson regression models compared LTFU incidence rate ratios (IRR) in the first six months after PMTCT enrollment and risk ratios compared uptake of six week testing for HIV-exposed infants (HEI) between the pre- and post-periods. RESULTS: In the pre-period, 223 (63.2%) of 353 pregnant AYWLH newly enrolled in ANC had ART data, while 320 (71.1%) of 450 in the post-period had ART data (p = 0.02). A higher proportion of women in the post-period (62.8%) had known HIV-positive status at first ANC visit compared to 49.3% in the pre-period (p < 0.001). Among pregnant AYWLH < 20 years, the incidence rate of LTFU in the first six months after enrollment in ANC services declined from 2.36 per 100 person months (95%CI 1.06-5.25) in the pre-period to 1.41 per 100 person months (95%CI 0.53-3.77) in the post-period. In both univariable and multivariable analysis, AYWLH < 20 years in the post-period were almost 40% less likely to be LTFU compared to the pre-period, although this finding did not meet the threshold for statistical significance (adjusted incidence rate ratio 0.62, 95%CI 0.38-1.01, p = 0.057). Testing for HEI was 10% higher overall in the post-period (adjusted risk ratio 1.10, 95%CI 1.01-1.21, p = 0.04). CONCLUSIONS: Interventions are urgently needed to improve outcomes among pregnant and postnatal AYWLH. We observed a trend towards increased retention among pregnant adolescents during our intervention and a statistically significant increase in uptake of six week HEI testing.

RESUMO

BACKGROUND: We describe tuberculosis (TB) disease among antiretroviral treatment (ART) eligible children living with HIV (CLHIV) in South Africa to highlight TB prevention opportunities. METHODS: In our secondary analysis among 0- to 12-year-old ART-eligible CLHIV in five Eastern Cape Province health facilities from 2012 to 2015, prevalent TB occurred 90 days before or after enrollment; incident TB occurred >90 days after enrollment. Characteristics associated with TB were assessed using logistic and Cox proportional hazards regression with generalized estimating equations. RESULTS: Of 397 enrolled children, 114 (28.7%) had prevalent TB. Higher-income proxy [adjusted odds ratio (aOR) 1.8 [95% confidence interval (CI) 1.3-2.6] for the highest, 1.6 (95% CI 1.6-1.7) for intermediate]; CD4+ cell count <350 cells/µl [aOR 1.6 (95% CI 1.1-2.2)]; and malnutrition [aOR 1.6 (95% CI 1.1-2.6)] were associated with prevalent TB. Incident TB was 5.2 per 100 person-years and was associated with delayed ART initiation [hazard ratio (HR) 4.7 (95% CI 2.3-9.4)], malnutrition [HR 1.8 (95% CI 1.1-2.7)] and absence of cotrimoxazole [HR 2.3 (95% CI 1.0-4.9)]. Among 362 children with data, 8.6% received TB preventive treatment. CONCLUSIONS: Among these CLHIV, prevalent and incident TB were common. Early ART, cotrimoxazole and addressing malnutrition may prevent TB in these children.


BACKGROUND: We describe tuberculosis (TB) in children living with HIV (CLHIV) eligible for HIV treatment in South Africa to highlight opportunities to prevent TB. METHODS: We analyzed additional data from our original study of CLHIV who were 0­12 years old and due to start HIV treatment in five health facilities in Eastern Cape Province from 2012 to 2015 and assessed characteristics associated with existing and new TB. RESULTS: Of 397 enrolled children, 114 (28.7%) had existing TB. Children with a higher measure of household income had higher odds of existing TB. CD4+ cell count <350 cells/µl and malnutrition were also associated with existing TB. There were 5.2 new cases of TB for every 100 child-years. New TB was 4.7 times more likely for children with delayed HIV treatment start, 1.8 times more likely for children with malnutrition and 2.3 times more likely for children who did not get cotrimoxazole. Among 362 children with data, 8.6% received treatment to prevent TB. CONCLUSIONS: Among these CLHIV, existing and new TB were common. Early HIV treatment, cotrimoxazole and addressing malnutrition may prevent TB in these children.

RESUMO

BACKGROUND: Children living with human immunodeficiency virus (HIV) (CLHIV) receiving antiretroviral therapy (ART) in resource-limited settings are susceptible to high rates of acquired HIV drug resistance (HIVDR), but few studies include children initiating age-appropriate World Health Organization (WHO)-recommended first-line regimens. We report data from a cohort of ART-naive South African children who initiated first-line ART. METHODS: ART-eligible CLHIV aged 0-12 years were enrolled from 2012 to 2014 at 5 public South African facilities and were followed for up to 24 months. Enrolled CLHIV received standard-of-care WHO-recommended first-line ART. At the final study visit, a dried blood spot sample was obtained for viral load and genotypic resistance testing. RESULTS: Among 72 successfully genotyped CLHIV, 49 (68.1%) received ABC/3TC/LPV/r, and 23 (31.9%) received ABC/3TC/EFV. All but 2 children on ABC/3TC/LPV/r were <3 years, and all CLHIV on ABC/3TC/EFV were ≥3 years. Overall, 80.6% (58/72) had at least one drug resistance mutation (DRM). DRMs to nonnucleoside reverse transcriptase inhibitors (NNRTIs) and nucleoside reverse transcriptase inhibitors (NRTIs) were found among 65% and 51% of all CLHIV, respectively, with no statistical difference by ART regimen. More CLHIV on ABC/3TC/EFV, 47.8% (11/23), were found to have 0 or only 1 effective antiretroviral drug remaining in their current regimen compared to 8.2% (4/49) on ABC/3TC/LPV/r. CONCLUSIONS: High levels of NNRTI and NRTI DRMs among CLHIV receiving ABC/3TC/LPV/r suggests a lasting impact of failed mother-to-child transmission interventions on DRMs. However, drug susceptibility analysis reveals that CLHIV with detectable viremia on ABC/3TC/LPV/r are more likely to have maintained at least 2 effective agents on their current HIV regimen than those on ABC/3TC/EFV.

RESUMO

In a national survey of 2074 US parents of children ≤12 years of age conducted in March 2021, 49.4% reported plans to vaccinate their child for coronavirus disease 2019 when available. Lower income and less education were associated with greater parental vaccine hesitancy/resistance; safety and lack of need were primary reasons for vaccine hesitancy/resistance.

RESUMO

BACKGROUND: Increased coagulation biomarkers are associated with poor outcomes among people living with HIV (PLHIV). There are few data available from African cohorts demonstrating the effect of antiretroviral therapy (ART) on coagulation biomarkers. METHODS: From March 2014 to October 2014, ART-naïve PLHIV initiating non-nucleoside reverse transcriptase inhibitor-based ART were recruited from seven clinics in western Kenya and followed for up to 12 months. Demographics, clinical history and blood specimens were collected. Logistic regression models adjusted for intrasite clustering examined associations between HIV viral load and D-Dimer at baseline. Mixed linear effects models were used to estimate mean change from baseline to 6 months overall, and by baseline viral load, sex and TB status at enrollment. Mean change in D-dimer at 6 months is reported on the log10 scale and as percentage change from baseline. RESULTS: Among 611 PLHIV enrolled, 66% were female, median age was 34 years (interquartile range (IQR) 29-43 years), 31 (5%) participants had tuberculosis and median viral load was 113,500 copies/mL (IQR: 23,600-399,000). At baseline, 311 (50.9%) PLHIV had elevated D-dimer (> 500 ng/mL) and median D-dimer was 516.4 ng/mL (IQR: 302.7-926.6) (log baseline D-dimer: 2.7, IQR: 2.5-3.0). Higher baseline D-dimer was significantly associated with higher viral load (p < 0.0001), female sex (p = 0.02) and tuberculosis (p = 0.02). After 6 months on ART, 518 (84.8%) PLHIV had achieved viral load < 1000 copies/mL and median D-dimer was 390.0 (IQR: 236.6-656.9) (log D-dimer: 2.6, IQR: 2.4-2.8). Mean change in log D-dimer from baseline to 6 months was - 0.12 (95%CI -0.15, - 0.09) (p < 0.0001) indicating at 31.3% decline (95%CI -40.0, - 23.0) in D-dimer levels over the first 6 months on ART. D-dimer decline after ART initiation was significantly greater among PLHIV with tuberculosis at treatment initiation (- 172.1, 95%CI -259.0, - 106.3; p < 0.0001) and those with log viral load > 6.0 copies/mL (- 91.1, 95%CI -136.7, - 54.2; p < 0.01). CONCLUSIONS: In this large Kenyan cohort of PLHIV, women, those with tuberculosis and higher viral load had elevated baseline D-dimer. ART initiation and viral load suppression among ART-naïve PLHIV in Kenya were associated with significant decrease in D-dimer at 6 months in this large African cohort.

RESUMO

BACKGROUND: Globally, the population of adolescents living with perinatally acquired HIV (APHs) continues to expand. In this study, we pooled data from observational pediatric HIV cohorts and cohort networks, allowing comparisons of adolescents with perinatally acquired HIV in "real-life" settings across multiple regions. We describe the geographic and temporal characteristics and mortality outcomes of APHs across multiple regions, including South America and the Caribbean, North America, Europe, sub-Saharan Africa, and South and Southeast Asia. METHODS AND FINDINGS: Through the Collaborative Initiative for Paediatric HIV Education and Research (CIPHER), individual retrospective longitudinal data from 12 cohort networks were pooled. All children infected with HIV who entered care before age 10 years, were not known to have horizontally acquired HIV, and were followed up beyond age 10 years were included in this analysis conducted from May 2016 to January 2017. Our primary analysis describes patient and treatment characteristics of APHs at key time points, including first HIV-associated clinic visit, antiretroviral therapy (ART) start, age 10 years, and last visit, and compares these characteristics by geographic region, country income group (CIG), and birth period. Our secondary analysis describes mortality, transfer out, and lost to follow-up (LTFU) as outcomes at age 15 years, using competing risk analysis. Among the 38,187 APHs included, 51% were female, 79% were from sub-Saharan Africa and 65% lived in low-income countries. APHs from 51 countries were included (Europe: 14 countries and 3,054 APHs; North America: 1 country and 1,032 APHs; South America and the Caribbean: 4 countries and 903 APHs; South and Southeast Asia: 7 countries and 2,902 APHs; sub-Saharan Africa, 25 countries and 30,296 APHs). Observation started as early as 1982 in Europe and 1996 in sub-Saharan Africa, and continued until at least 2014 in all regions. The median (interquartile range [IQR]) duration of adolescent follow-up was 3.1 (1.5-5.2) years for the total cohort and 6.4 (3.6-8.0) years in Europe, 3.7 (2.0-5.4) years in North America, 2.5 (1.2-4.4) years in South and Southeast Asia, 5.0 (2.7-7.5) years in South America and the Caribbean, and 2.1 (0.9-3.8) years in sub-Saharan Africa. Median (IQR) age at first visit differed substantially by region, ranging from 0.7 (0.3-2.1) years in North America to 7.1 (5.3-8.6) years in sub-Saharan Africa. The median age at ART start varied from 0.9 (0.4-2.6) years in North America to 7.9 (6.0-9.3) years in sub-Saharan Africa. The cumulative incidence estimates (95% confidence interval [CI]) at age 15 years for mortality, transfers out, and LTFU for all APHs were 2.6% (2.4%-2.8%), 15.6% (15.1%-16.0%), and 11.3% (10.9%-11.8%), respectively. Mortality was lowest in Europe (0.8% [0.5%-1.1%]) and highest in South America and the Caribbean (4.4% [3.1%-6.1%]). However, LTFU was lowest in South America and the Caribbean (4.8% [3.4%-6.7%]) and highest in sub-Saharan Africa (13.2% [12.6%-13.7%]). Study limitations include the high LTFU rate in sub-Saharan Africa, which could have affected the comparison of mortality across regions; inclusion of data only for APHs receiving ART from some countries; and unavailability of data from high-burden countries such as Nigeria. CONCLUSION: To our knowledge, our study represents the largest multiregional epidemiological analysis of APHs. Despite probable under-ascertained mortality, mortality in APHs remains substantially higher in sub-Saharan Africa, South and Southeast Asia, and South America and the Caribbean than in Europe. Collaborations such as CIPHER enable us to monitor current global temporal trends in outcomes over time to inform appropriate policy responses.

RESUMO

OBJECTIVE: To describe pediatric ART scale-up in Ethiopia, one of the 21 global priority countries for elimination of pediatric HIV infection. METHODS: A descriptive analysis of routinely collected HIV care and treatment data on HIV-infected children (<15 years) enrolled at 70 health facilities in four regions in Ethiopia, January 2006-September 2013. Characteristics at enrollment and ART initiation are described along with outcomes at 1 year after enrollment. Among children who initiated ART, cumulative incidence of death and loss to follow-up (LTF) were estimated using survival analysis. RESULTS: 11 695 children 0-14 years were enrolled in HIV care and 6815 (58.3%) initiated ART. At enrollment, 31.2% were WHO stage III and 6.3% stage IV. The majority (87.9%) were enrolled in secondary or tertiary facilities. At 1 year after enrollment, 17.9% of children were LTF prior to ART initiation. Among children initiating ART, cumulative incidence of death was 3.4%, 4.1% and 4.8%, and cumulative incidence of LTF was 7.7%, 11.8% and 16.6% at 6, 12 and 24 months, respectively. Children <2 years had higher risk of LTF and death than older children (P < 0.0001). Children with more advanced disease and those enrolled in rural settings were more likely to die. Children enrolled in more recent years were less likely to die but more likely to be LTF. CONCLUSIONS: Over the last decade large numbers of HIV-infected children have been successfully enrolled in HIV care and initiated on ART in Ethiopia. Retention prior to and after ART initiation remains a major challenge.

RESUMO

Data suggest that pregnant women in some settings have high prevalence of HIV and other sexually transmitted infections (STI). We examined changes in sexual risk behaviors and intravaginal practices during pregnancy that may contribute to HIV and STI incidence using data from the Methods for Improved Reproductive Health in Africa study conducted in South Africa and Zimbabwe 2003-2006. We used a crossover design and modified Poisson regression to compare behaviors among HIV negative women 18-45 years during pregnant and non-pregnant periods. Among the 4802 women <45 years at enrollment, 483 (10.1 %) had a pregnancy and were included in the analysis. Compared to non-pregnant periods, pregnancy was associated with fewer than 3 sex acts per week (adjusted risk ratio [ARR] 0.89; 95 % CI 0.79-0.99) but more sex acts without condoms (ARR 1.32; 95 % CI 1.15-1.51). Pregnancy was also associated with decreased reporting of other sexual risk behaviors including any anal sex, multiple sexual partners, and/or sex in exchange for drugs or money. Women also reported less intravaginal wiping during pregnancy (ARR 0.84; 95 % CI 0.76-0.93). We found pregnancy decreased sexual activity and some high-risk sexual behaviors but increased the risk of sex without a condom.

RESUMO

Most studies examining factors associated with pediatric influenza (flu) and coronavirus disease (COVID-19) vaccination uptake focus on parental demographics. We examined whether the childhood cultural health environment (CHE) of parents (measured by self-reported regular attendance at doctor and dentist visits during childhood) was associated with flu and COVID-19 vaccination of their children. Using 2023 survey data from 397 US parents and causal inference methods, we estimated the average causal effect of parental CHE on flu vaccination rates (0.16 [95 % confidence interval: 0.06,0.27]) and COVID-19 (0.14 [95 % confidence interval: 0.04,0.24]), indicating that if all parents had attended regular doctor/dentist visits as children, flu and COVID-19 vaccination rates in children would be 16 % and 14 % higher, respectively, than if none had. Our findings suggest that early life exposure to medical and dental care has significant and lasting effects on the health of individuals and families.

RESUMO

BACKGROUND: Understanding the relationship between race/ethnicity, birthplace, and health outcomes is important for reducing health disparities. This study assessed the relationship between racial/ethnic identity and minority racial/ethnic status in country of birth on influenza vaccination among New York City (NYC) adults. METHODS: Using 2015-2019 data from NYC's Community Health Surveys, we assessed the association between racial/ethnic identity and racial/ethnic minority status in birth country with past year influenza vaccination, calculating prevalence differences per 100 and assessing interaction on the additive scale using linear binomial regression, and prevalence ratios and interaction on the multiplicative scale using log-binomial regression. RESULTS: Effect modification between race/ethnicity and minority racial/ethnic status in birth country was significant on the additive scale for Hispanic (p = 0.018) and Black (p = 0.025) adults and the multiplicative scale for Hispanic adults (p = 0.040). After stratifying by racial/ethnic minority or majority status in birth country, vaccination was significantly lower among Black adults compared with White adults among those in the minority (adjusted prevalence difference [aPD]=-12.98, 95%CI: -22.88-(-2.92)) and significantly higher among Hispanic adults compared with White adults among those in the majority (aPD=9.28, 95%CI: 7.35-11.21). CONCLUSIONS: Racial/ethnic minority status in birth country is an important factor when examining racial/ethnic differences in vaccination status.

RESUMO

OBJECTIVE: To measure annual rates of road traffic injuries (RTI) and to describe the characteristics of road traffic crashes experienced by children and adolescents in Tanga, Tanzania. METHODS: We conducted a cross-sectional household survey using geospatial population-weighted sampling in the city of Tanga in northern Tanzania. Data were collected in February and March of 2022. We report 12-month rates of road traffic crashes and RTI (reported by adult caregivers) among children and adolescents <18 years of age. RESULTS: A total of 2,794 adult respondents reported data on 6563 children and adolescents, among whom, 180 were reported to have experienced road traffic crashes in the past 12 months (crash incidence: 27.4 per 1,000 children, 95%CI 23.5-31.4) and 158 sustained injuries (RTI incidence: 24.1 per 1000 children, 95%CI 20.4-27.8). Almost a quarter of RTI (23%) were reported to be major (resulting in ≥30 days of missed activities). RTI was higher among adolescents (13-17 years) than children <5 years (21.5 vs. 14.1 per 1,000, p=0.039). Few children always or sometimes wore helmets when riding on motorcycles/motorbikes (12.8%) or wore safety restraints/seat belts in cars or other vehicles (11.9%). CONCLUSION: The high rate of road traffic crashes and RTI observed among children and adolescents in a medium-sized city in Tanzania underscores the urgent need to improve road safety and increase use of safety equipment in low resource settings.

RESUMO

BACKGROUND: Routine case surveillance data for SARS-CoV-2 are incomplete, unrepresentative, missing key variables of interest, and may be increasingly unreliable for timely surge detection and understanding the true burden of infection. METHODS: We conducted a cross-sectional survey of a representative sample of 1030 New York City (NYC) adult residents ≥18 years on May 7-8, 2022. We estimated the prevalence of SARS-CoV-2 infection during the preceding 14-day period. Respondents were asked about SARS-CoV-2 testing, testing outcomes, COVID-like symptoms, and contact with SARS-CoV-2 cases. SARS-CoV-2 prevalence estimates were age- and sex-adjusted to the 2020 U.S. POPULATION: We triangulated survey-based prevalence estimates with contemporaneous official SARS-CoV-2 counts of cases, hospitalizations, and deaths, as well as SARS-CoV-2 wastewater concentrations. RESULTS: We show that 22.1% (95% CI 17.9-26.2%) of respondents had SARS-CoV-2 infection during the two-week study period, corresponding to ~1.5 million adults (95% CI 1.3-1.8 million). The official SARS-CoV-2 case count during the study period is 51,218. Prevalence is estimated at 36.6% (95% CI 28.3-45.8%) among individuals with co-morbidities, 13.7% (95% CI 10.4-17.9%) among those 65+ years, and 15.3% (95% CI 9.6-23.5%) among unvaccinated persons. Among individuals with a SARS-CoV-2 infection, hybrid immunity (history of both vaccination and infection) is 66.2% (95% CI 55.7-76.7%), 44.1% (95% CI 33.0-55.1%) were aware of the antiviral nirmatrelvir/ritonavir, and 15.1% (95% CI 7.1-23.1%) reported receiving it. Hospitalizations, deaths and SARS-CoV-2 virus concentrations in wastewater remained well below that during the BA.1 surge. CONCLUSIONS: Our findings suggest that the true magnitude of NYC's BA.2/BA.2.12.1 surge may have been vastly underestimated by routine case counts and wastewater surveillance. Hybrid immunity, bolstered by the recent BA.1 surge, likely limited the severity of the BA.2/BA.2.12.1 surge.


It is difficult to assess the true prevalence of SARS-CoV-2, the virus that causes COVID-19, due to changes in testing practices and behaviors, including increasing at-home testing and decreasing healthcare provider-based testing. We conducted a population-representative survey in New York City to estimate the prevalence of SARS-CoV-2 during the second Omicron surge in spring 2022. We compared survey-based SARS-CoV-2 prevalence estimates with data on diagnosed cases, hospitalizations, deaths, and SARS-CoV-2 concentration in wastewater. Our survey-based estimates were nearly 30 times higher than official case counts and estimates of immunity among those with active infection were high. Taken together, our results suggest that the magnitude of the second Omicron surge was likely significantly underestimated, and high levels of immunity likely prevented a major surge in hospitalizations/deaths. Our findings might inform future work on COVID-19 surveillance and how to mitigate its spread.

RESUMO

BACKGROUND: Repeat HIV testing during pregnancy and breastfeeding identifies women with incident infections, those living with HIV who have been lost to care, and infants at risk for HIV infection. We report data from repeat testing for women in maternal and child health (MCH) services at 10 health facilities in Mozambique. METHODS: Routinely collected data from health facility registers are reported from April-November 2019. From antenatal care (ANC), we report numbers and proportions of women eligible for retesting; returned for care when retesting eligible; retested; and HIV-positive (HIV+) at retesting. From child welfare clinics (CWC), we report mothers retested; tested HIV-positive; HIV+ mothers linked to ART services; HIV-exposed infants (HEI) tested for HIV with polymerase chain reaction (PCR) tests; HEI testing PCR positive; PCR-positive infants linked to care. RESULTS: In ANC, 28,233 pregnant women tested HIV-negative at first ANC visit, 40.7% had a follow-up visit when retesting eligible, among whom 84.8% were retested and 0.3%(N = 26) tested HIV+. In CWC, 26,503 women were tested; 0.8%(N = 212) tested HIV+ and 74.1%(N = 157) of HIV+ women were linked to care. Among 157 HEI identified in CWC, 68.4%(N = 145) received PCR testing and 19.3%(N = 28) tested positive. CONCLUSION: In ANC, less than half of pregnant women eligible for retesting returned for follow-up visits, and test positivity was low among women retested in ANC and CWC. In CWC, linkage to infant testing was poor and almost 20% of HEI were PCR-positive. Implementing retesting for pregnant and breastfeeding women is challenging due to high numbers of women and low testing yield.
