Differences in Influenza Vaccination Coverage between Adult Immigrants and Italian Citizens at Risk for Influenza-Related Complications: A Cross-Sectional Study

IntroductionThe Centers for Disease Control and Prevention (CDC) spend significant time and resources to track influenza vaccination coverage each influenza season using national surveys. Emerging data from social media provide an alternative solution to surveillance at both national and local levels of influenza vaccination coverage in near real time.ObjectivesThis study aimed to characterise and analyse the vaccinated population from temporal, demographical and geographical perspectives using automatic classification of vaccination-related Twitter data.MethodsIn this cross-sectional study, we continuously collected tweets containing both influenza-related terms and vaccine-related terms covering four consecutive influenza seasons from 2013 to 2017. We created a machine learning classifier to identify relevant tweets, then evaluated the approach by comparing to data from the CDC’s FluVaxView. We limited our analysis to tweets geolocated within the USA.ResultsWe assessed 1 124 839 tweets. We found strong correlations of 0.799 between monthly Twitter estimates and CDC, with correlations as high as 0.950 in individual influenza seasons. We also found that our approach obtained geographical correlations of 0.387 at the US state level and 0.467 at the regional level. Finally, we found a higher level of influenza vaccine tweets among female users than male users, also consistent with the results of CDC surveys on vaccine uptake.ConclusionSignificant correlations between Twitter data and CDC data show the potential of using social media for vaccination surveillance. Temporal variability is captured better than geographical and demographical variability. We discuss potential paths forward for leveraging this approach.

Significant Public Health

Influenza is a significant public health problem and the elderly are at a greater risk of contracting the disease. The vaccination coverage of the elderly is below the Spanish target of 65% for each influenza season. The aims of this study were to report the coverage of influenza vaccination in Spain among the population aged ≥65 years and high-risk groups for suffering chronic diseases, to analyze the time trends from 2006 to 2017 and to identify the factors which affect vaccination coverage. A nationwide cross-sectional study was conducted including 20,753 non-institutionalized individuals aged ≥65 years who had participated in the Spanish National Health Surveys in 2006, 2011/2012, and 2017. Sociodemographic, health-related variables, and influenza vaccination data were used. A logistic regression analysis was performed to determine the variables associated with influenza vaccination. Influenza vaccination coverage was 60%. By chronic condition, older people with high cholesterol levels and cancer had the lowest vaccination coverage (62.41% and 60.73%, respectively). This coverage declined from 2006 to 2017 in both groups. Higher influenza vaccination was associated with males, Spanish nationality, normal social support perceived, polypharmacy, worse perceived health, participation in other preventive measures, and increasing age and the number of chronic diseases.

Abstract Background: The implications of congenital Zika Virus (ZIKV) infections for pediatric neurodevelopment and behavior remain inadequately studied. The aim of this study is to investigate patterns of neurodevelopment and behavior in children with different levels of ZIKV-related microcephaly or with prenatal ZIKV exposure in the absence of microcephaly. Methods: We conducted a cross-sectional study, nested in a cohort, of 274 children (aged 10-45 months) who were born during the peak and decline of the microcephaly epidemic in Northeast Brazil. Participants were evaluated between February 2017 and August 2019 at two tertiary care hospitals in Recife, Brazil. We analyzed the children in four groups assigned based on clinical and laboratory criteria: Group 1 had severe microcephaly; Group 2 had moderate microcephaly; Group 3 had prenatal ZIKVxposure confirmed by maternal RT-PCR testing and no microcephaly; and Group 4 was a neurotypical control group. Groups were evaluated clinically for neurological abnormalities and compared using the Survey of Wellbeing of Young Children (SWYC), a neurodevelopment and behavior screening instrument, and a SWYC adapted form to compare severe cases. Results: Based on the SWYC screening, we observed differences between the groups for developmental milestones but not behavior. Among children with severe microcephaly of whom 98.2% presented with neurological abnormalities, 99.1% were at risk of development delay, and presented similar performance whether evaluated under or over 24 months of age. Among children with moderate microcephaly of whom 60% presented with neurological abnormalities, 65% were at risk of development delay. For children without microcephaly, the percentages found to be at risk of developmental delays were markedly lower and did not differ by prenatal ZIKV exposure status: Groups 3, 13.8%; Group 4, 21.7%. Conclusions: Among groups of children with prenatal ZIKV exposure, we found a gradient of risk of development delay. Children with severe microcephaly were at highest risk, while normocephalic ZIKV-exposed children had similar risks to unexposed control children. We propose that ZIKV-exposed children should undergo first-line screening for neurodevelopment and behavior using the SWYC. Early assessment and follow-up will enable at-risk children to be referred to a more comprehensive developmental evaluation and to multidisciplinary care management.

Healthy Start Program

Objective. To describe family identification, family engagement, and service delivery in a statewide home visiting program for at-risk families of newborns. Setting. Six target communities of Hawaii's Healthy Start Program (HSP), which incorporates 1) early identification of at-risk families of newborns via population-based screening and assessment, and 2) paraprofessionalhome visiting to improve family functioning, promote child health and development, and prevent child maltreatment. Design. Cross-sectional study: describes early identification process and family characteristics associated with initial enrollment. Longitudinal study: describes home visiting process and characteristics associated with continued participation. Subjects. Cross-sectional study: civilian births in 6 communities (n = 6553). Longitudinal study: at-risk families in the intervention group of a randomized trial of the HSP (n = 373). Measures. Process: completeness and timeliness of early identification and home visiting activities; family characteristics: sociodemographics, child abuse risk factors, infant biologic risk. Results. Early identification staff determined risk status for 84% of target families. Families with higher risk scores, young mothers with limited schooling, and families with infants at biologic risk were more likely to enroll in home visiting. Half of those who enrolled were active at 1 year with an average of 22 visits. Families where the father had multiple risk factors and where the mother was substance abusing were more likely to have ≥12 visits; mothers who were unilaterally violent toward the father were less likely. Most families were linked with a medical home; linkage rates for other community resources varied widely by type of service. Half of families overall, but ≥80% of those active at 1 year, received core home visiting services. Performance varied by program site. Conclusions. It is challenging to engage and retain at-risk families in home visiting. Service monitoring must be an integral part of operations.
