Filter by:Influenza infection results in an estimated 31 million outpatient visits, 55,000 to 974,200 hospitalizations, and 3,000 to 49,000 deaths. Membership in household in which someone else has influenza is the major risk factor for contracting influenza. The household secondary attack rate (SAR) is as high as 19% based on laboratory-confirmed influenza and 30% based on symptoms. Non-pharmaceutical preventive measures, including education, may play a role in decreasing transmission, but are only effective if started within 36 hours of symptom onset in index cases. Yet, most interventions are delayed because they are not initiated until care is sought. The investigators have demonstrated in one primarily Latino, urban community sample, that text messaging can be used to rapidly identify community members with influenza-like illness (ILI) early in an illness. This early identification would enable implementation of an educational intervention in the optimal time frame to reduce influenza transmission. Providing education within a text message is a proven successful strategy to influence behavior. Text messaging itself is scalable, low-cost, and can be used in low literacy populations. However, using text-message based surveillance to trigger a real-time text-message behavioral educational intervention to decrease household influenza transmission has not been assessed.
The purpose of the study is to compare Emergency Department patients who undergo influenza testing using an FDA-approved point-of-care device (Cobas Liat Influenza A/B assay) located in the ED, to patients whose samples are sent to the BMC central laboratory. Patients who agree to participate will have their samples randomly assigned to be tested on either at the core lab, or on the POC device. The current turnaround time for samples sent to the laboratory is approximately two hours; investigators expect that the point of care device can reduce this time. Investigators will determine if the time to disposition and the administration of antibiotics is different in the group undergoing POC influenza testing compared to those undergoing laboratory-based influenza testing
This study is powered to prospectively evaluate the relative effectiveness of adjuvanted trivalent influenza vaccine (aTIV; FLUAD) in preventing influenza mortality, hospitalization, and functional decline in a nursing home population in the U.S., compared to the commercially available, standard dose trivalent seasonal influenza vaccine (TIV; Fluvirin).
There is no standardized method for evaluating the symptoms of influenza. A standardized instrument for measuring influenza symptoms, with appropriate scientifically derived content and construct validity would have value for public health in terms of use as a validated outcome measure in interventions to treat or prevent influenza. The instrument also could serve as part of an overall measure of severity of illness in influenza. Previous efforts in participant reported outcomes (PRO) for influenza (i.e. Flu-PRO Stage I and Stage II) focused on the elicitation and evaluation of items for inclusion in the instrument. The overarching objective of this protocol - Flu-PRO Stage III - is to conduct instrument validation to evaluate item properties and, if need be, reduce the number of items, and quantitatively validate the performance of the final measure.
Previous work has shown that the epidemiological context of a patient's presentation can provide important information for clinicians to aid in diagnosis and treatment. With current electronic health records, it is increasingly possible to perform syndromic surveillance that is local and specific to a patient's characteristics. The investigators have developed algorithms for syndromic surveillance for a number of conditions in which contextual information might be of use to treating clinicians. The syndromic surveillance algorithms already developed are for influenza-like-illness, whooping cough, asthma exacerbation, Group A Streptococcal pharyngitis, and gastroenteritis infection. The investigators plan on studying these tools with a clustered randomized control cohort study evaluating how clinical decision making is affected by use of these tools by outpatient general practitioners. The goal is to incorporate these validated algorithms into a quality improvement tool which will provide point-of-care clinical decision support to clinicians
This is a prospective specimen collection study targeting patients presenting with Influenza Like Illness (ILI) and/or Acute Respiratory Infection (ARI) in an out-patient setting. A non-invasive, user friendly sampling technique, using midturbinate flocked swabs will be used. These nasal swabs will be collected in different volumes of viral transport media (0.5mL and 3.0mL), for different dilution range of the viruses present in the collected biological specimen. The collection of nasal swabs samples will support the optimization of point of care detection methods for respiratory viruses responsible for ILI and/or ARI.
Influenza is an important cause of acute respiratory infections (ARI) worldwide. Seasonal influenza causes an estimated 250,000-500,000 deaths and 3-5 million severe illnesses each year (WHO, 2009), and pandemic 2009 H1N1 influenza has caused morbidity and mortality worldwide. In Kenya, influenza accounts for up to 50% of all ARI during the peak influenza season, based on Kenyan Ministry of Public Health and Sanitation and KEMRI/CDC surveillance data. Influenza vaccine has been shown to reduce influenza-associated ARIs in developed countries. However, little is know about the effectiveness of influenza vaccine in the developing world. In Kenya, a commercial trivalent injectable vaccine is licensed, but less than 30,000 doses are sold annually. The International Emerging Infections Program (IEIP) under KEMRI/CDC currently conducts population-based disease surveillance (PBDS) for severe acute respiratory illness (SARI) and influenza-like illness (ILI) in two sites in Kenya, Lwak (Nyanza province) and Kibera (Nairobi). The investigators propose to conduct a three-year influenza vaccine effectiveness study using the commercially available southern hemisphere seasonal vaccine for 2010, which includes the pandemic 2009 H1N1 component, and for 2011 and 2012. The study will evaluate the effectiveness of the vaccine in preventing laboratory-confirmed influenza, non-specific ARIs at the clinic and household level, and secondary influenza infection and secondary ARIs. Our study hypothesis is: Immunizing children with influenza vaccine will decrease influenza-associated acute respiratory infections among children and may reduce the number of non-specific acute respiratory infections in vaccinated children and their household contacts.
A study to characterize children and adults with influenza like symptoms and to determine risk factors for severe disease and death among those with H1N1.
The purpose of this study is to determine the degree of indirect benefits to family members and classmates resulting from administration of influenza vaccine to children.
We will be testing the hypothesis whether online education for UC Berkeley students on respiratory hygiene, cough etiquette, hand hygiene/awareness, as well as face mask use (while ill) will reduce the acquisition and transmission of influenza-like illness. The study will be conducted during the flu seasons 2006-7 and 2007-8.
