The formulation of accurate clinical case definitions is an integral part effective process public health surveillance. Although such should, ideally, be based on a standardized and fixed collection defining criteria, they often require revision to reflect new knowledge the condition involved improvements in diagnostic testing. Optimal also need have balance sensitivity specificity that reflects their intended use. After 2009-2010 H1N1 influenza pandemic, World Health Organization (WHO)...
To examine the reliability of self-reported age first substance use experiences among national samples adult and child respondents.Survey responses from seven waves National Longitudinal Survey Youth (NLSY) were examined.Adult NLSY respondents reporting tobacco, alcohol, marijuana, cocaine and/or crack during two or more survey interviews.Four indicators reliability: intraclass correlation coefficients (ICC), mean absolute differences in reported reports consistent within 1 year.The adjusted...
Please cite this paper as: Vega et al. (2012) Influenza surveillance in Europe: establishing epidemic thresholds by the moving method. and Other Respiratory Viruses 7(4), 546–558. Background Timely influenza is important to monitor epidemics. Objectives (i) To calculate threshold for influenza‐like illness (ILI) acute respiratory infections (ARI) 19 countries, as well different levels of intensity. (ii) evaluate performance these thresholds. Methods The method (MEM) has been developed...
In response to the potential threat of an influenza pandemic, several international institutions and governments, in partnership with African countries, invested development epidemiologic laboratory surveillance capacity Africa Network Influenza Surveillance Epidemiology (ANISE) was formed.We used a standardized form collect information on system characteristics, number percent influenza-positive patients influenza-like illness (ILI), or severe acute respiratory infection (SARI) virologic...
Influenza disease burden varies by age and this has important public health implications. We compared the proportional distribution of different influenza virus types within strata using surveillance data from twenty-nine countries during 1999-2014 (N=358,796 cases). For each virus, we calculated a Relative Illness Ratio (defined as ratio percentage cases in an group to country population same group) for young children (0-4 years), older (5-17 adults (18-39 (40-64 elderly (65+ years). used...
Objectives To assess the health effects of exposure to smoke fromthe fifth largest US wildfire 1999 and evaluate whether participation ininterventions reduce prevented adverse lower respiratorytract among residents Hoopa Valley National IndianReservation in northwestern California. Design Observational study:epidemiologists from Centers for Disease Control Preventionretrospectively reviewed medical records at local center andconducted survey interviews reservation residents.

Carbon monoxide (CO) has been reported to contribute more than 2000 poisoning deaths per year in the United States.To evaluate influence of national vehicle emissions policies and practices on CO-related mortality describe 31 years (1968-1998) States.Longitudinal trend analysis using computerized death data from Centers for Disease Control Prevention, US Census Bureau population data, annual CO estimates light-duty vehicles provided by Environmental Protection Agency.All which...
In the United States, among Hispanics, Mexican Americans have lowest rate of asthma. However, this population includes born in States and Mexico, risk factors that might impact prevalence asthma differ between these groups. To determine for U.S.- Mexican-born Americans, we analyzed data from two U.S. surveys included 4,574 persons who self-reported their ethnicity as American Third National Health Nutrition Examination Survey (NHANES III) 1998-1994 12,980 Interview (NHIS) 1997-2001....
Background In Kenya, detailed data on the age-specific burden of influenza and RSV are essential to inform use limited vaccination treatment resources. Methods We analyzed surveillance from August 2009 July 2012 for hospitalized severe acute respiratory illness (SARI) outpatient influenza-like (ILI) at two health facilities in western Kenya estimate syncytial virus (RSV). Incidence rates were estimated by dividing number cases with laboratory-confirmed infections mid-year population. Rates...
Introduction Determining the optimal time to vaccinate is important for influenza vaccination programmes. Here, we assessed temporal characteristics of epidemics in Northern and Southern hemispheres tropics, discuss their implications Methods This was a retrospective analysis surveillance data between 2000 2014 from Global Influenza B Study database. The seasonal peak defined as week with most reported cases (overall, A, B) season. duration activity using maximum proportion during three...
Reducing acute respiratory infection burden in children Africa remains a major priority and challenge. We analyzed data from population-based infectious disease surveillance for severe illness (SARI) among <5 years of age Kibera, densely populated urban slum Nairobi, Kenya. Surveillance was conducted monthly mean 5,874 (range = 5,778-6,411) old two contiguous villages Kibera. Participants had free access to the study clinic their health events utilization were noted during biweekly home...
Abstract Among 11 patients in Thailand infected with severe acute respiratory syndrome coronavirus 2, we detected viral RNA upper specimens a median of 14 days after illness onset and 9 fever resolution. We identified co-infections an asymptomatic person detectable virus serial tests. describe implications for surveillance.
The current study examined the interactive effects of infant activity level and fear on growth trajectories behavior problems in early childhood (age 4 to 8 years) using maternal ratings. sample was drawn from National Longitudinal Survey Youth (NLSY) included children who were between 1 11 months 1986. Findings suggested that boys characterized by high low levels infancy escalated both externalizing internalizing symptoms. Also, increased symptoms these seemed be specific depression rather...
Abstract In the current study, two mediational mechanisms, parenting practices and children's beliefs about aggression, were hypothesized to account for relationship between perceived neighborhood danger childhood aggression. Using structural equation modeling, data analyzed from an inner‐city school‐based sample of 732 predominantly African American 5th graders. Results suggested that was associated with strong positive which in turn high levels The mediating role (restrictive discipline,...
Background Recent studies have shown that influenza is associated with significant disease burden in many countries the tropics, but until recently national surveillance for was not conducted most Africa. Methods In 2007, Kenyan Ministry of Health technical support from CDC-Kenya established a sentinel system influenza. At 11 hospitals, every hospitalized patient severe acute respiratory illness (SARI), and first three outpatients influenza-like (ILI) per day, we collected both...
Methods. From January to April 2013, 28 African countries were invited participate in a review of severe acute respiratory illness (SARI)–associated deaths identified from influenza surveillance during 2009–2012.
Low global influenza circulation was reported during the coronavirus-19 pandemic. We explored relationships between non-pharmaceutical interventions (NPIs) and in tropical Asian countries.
Background Knowing the national disease burden of severe influenza in low-income countries can inform policy decisions around treatment and prevention. We present a novel methodology using locally generated data for estimating this burden. Methods Findings This method begins with calculating hospitalized acute respiratory illness (SARI) incidence children <5 years old persons ≥5 from population-based surveillance one province. base rate SARI is then adjusted each province based on prevalence...
For disease surveillance, manual data collection using paper-based questionnaires can be time consuming and prone to errors. We introduced smartphone replace for an influenza sentinel surveillance system in four hospitals Kenya. compared the quality, cost timeliness of between system. Since 2006, Kenya Ministry Health (MoH) with technical support from Medical Research Institute/Centers Disease Control Prevention (KEMRI/CDC) conducted hospital-based In May 2011, MOH replaced electronic Field...
