an outbreak of an influenza-like illness in a nursing home.as part of an ongoing infection surveillance program, data were collected on an outbreak of respiratory illness affecting 29% of residents in a 231-bed long-term care facility. viral titers could be collected on 60% of the ill residents and respiratory syncytial virus (rsv) was established in 14 of the symptomatic patients and was thought to be the probable cause of the outbreak. compared with previously reported long-term institutional outbreaks of rsv, there were significantly fewer cases of p ...19902358628
a concurrent epidemic of respiratory syncytial virus and echovirus 7 infections in an intensive care nursery.we describe concurrent outbreaks of respiratory syncytial virus (rsv) and echovirus 7 (echo 7) infections in a neonatal intensive care unit, including infants who had dual infections. seventy-three infants were identified as having rsv from january through june, 1984. during the same surveillance period echo 7 was cultured from 20 infants, and 6 infants had concurrent rsv and echo 7 and rsv were isolated, but not concurrently. this dual outbreak of rsv and echo 7 infections persisted for months ...19892922234
survey of desert bighorn sheep in california for exposure to selected infectious diseases.from february 1983 to june 1985, 188 desert bighorn sheep (ovis canadensis nelsoni, = 161 and oc cremnobates, = 27) from 18 herds in 17 mountain ranges and one captive herd were caught, marked, and had blood, fecal, and nasal mucus samples collected. nasal swab specimens were cultured bacteriologically and virologically specifically for parainfluenza-3 (pi-3) virus. bacterial flora differed from herd to herd. pathogenic pneumophilic bacteria (eg, pasteurella sp) seldom were found. parainfluenza- ...19853878356
an outbreak of respiratory syncytial virus pneumonia in a nursing home for the elderly.an outbreak of pneumonia and febrile respiratory illness took place in a los angeles county nursing home for the elderly in february and march of 1979. forty of 101 (40%) residents were affected. twenty-two (55%) had pneumonia and eight (20%) died. the outbreak extended over a period of 6 weeks. serological evidence implicated respiratory syncytial virus (rsv) as the causative agent. three patients had fourfold or greater rises in the titre of antibody to rsv, one had high titres in paired sampl ...19846527041
clinical profile of pediatric patients hospitalized with respiratory syncytial virus infection.to update the clinical profile of pediatric patients hospitalized with rsv infection, we retrospectively reviewed the records of 246 children (male:female ratio 1.44:1) admitted during one season to a tertiary-care hospital. the most common admitting diagnoses were bronchiolitis (37.4%), pneumonia (32.5%), and possible septicemia (13%). median age was 3 months; median length of stay, three days. twice as many minorities were admitted with rsv infection as all other admissions during the same yea ...19938104752

rehospitalization for respiratory syncytial virus among premature infants.new interventions to prevent respiratory syncytial virus (rsv) have recently become available. clinical decisions about the use of these interventions require a better understanding of the incidence of and risk factors for rsv. we sought to characterize the epidemiology of severe rsv disease among premature infants and to identify high-risk subgroups.199910506231
rate of palivizumab administration in accordance with current recommendations among hospitalized children.the american academy of pediatrics recommends palivizumab prophylaxis for children born premature or with chronic lung disease to reduce the severity of respiratory syncytial virus (rsv) infection. the purpose of the current study is to examine palivizumab administration among children hospitalized with rsv infection.200415337916
characterization of viral agents causing acute respiratory infection in a san francisco university medical center clinic during the influenza season.with use of polymerase chain reaction (pcr) and a centrifugation-enhanced viral culture method, we characterized the viruses causing acute respiratory infection in adults during an influenza season.200516107980
hospitalization for respiratory syncytial virus among california infants: disparities related to race, insurance, and geography.to evaluate population-based rates of respiratory syncytial virus (rsv)-associated infant hospitalizations related to race/ethnicity, payer source, and geography in california.200616939750
impact of palivizumab on rsv hospitalizations for children with hemodynamically significant congenital heart disease.the objective of this study was to evaluate the impact of palivizumab prophylaxis on respiratory syncytial virus (rsv) hospitalizations among children with hemodynamically significant congenital heart disease (chd). in 2003, the american academy of pediatrics (aap) revised the bronchiolitis policy statement and recommended the use of palivizumab in children <24 months old with hemodynamically significant chd (hs-chd). california statewide hospital discharge data from years 2000-2002 (pre-aap pol ...201019915892
respiratory syncytial virus testing during bronchiolitis episodes of care in an integrated health care delivery system: a retrospective cohort study.bronchiolitis has the highest incidence rate of any lower respiratory infection among infants and children <2 years of age. respiratory syncytial virus (rsv) is the most common etiology of bronchiolitis. the american academy of pediatrics does not recommend routine rsv testing for infants and children with bronchiolitis. the clinical predictors of rsv testing are unknown. objectives: the aims of this study were to identify the rates and predictors of rsv testing during bronchiolitis and to explo ...201021316538
sars and common viral infections.in california, molecular testing was useful in decreasing suspicion for severe acute respiratory syndrome (sars), by detecting common respiratory pathogens (influenza a/b, human metapneumovirus, picornavirus, mycoplasma pneumoniae, chlamydia spp., parainfluenza virus, respiratory syncytial virus, and adenovirus) in 23 (45%) of 51 patients with suspected sars and 9 (47%) of 19 patients with probable sars.200415207072

influenza and the rates of hospitalization for respiratory disease among infants and young children.young children may be at increased risk for serious complications from influenzavirus infection. however, in population-based studies it has been difficult to separate the effects of influenzavirus from those of respiratory syncytial virus. respiratory syncytial virus often circulates with influenzaviruses and is the most frequent cause of hospitalization for lower respiratory tract infections in infants and young children. we studied the rates of hospitalization for acute respiratory-disease am ...200010648764
administration of ribavirin to neonatal and pediatric patients during mechanical ventilation.we have modified the circuits of pressure-preset and volume-preset ventilators to permit the administration of ribavirin to mechanically ventilated infants suffering from respiratory syncytial virus. the modifications isolate the ventilator itself and permit continuous aerosolization for as long as seven days without ventilator malfunction from the effects of crystallized medication. excessive spilling of ribavirin into the environment is also avoided. each institution must devise its own experi ...198610315718
pneumonia in military recruits.lower respiratory disease is a major source of morbidity in military recruits, with hospitalization rates for pneumonia more than 30 times that of the non-recruit population. the etiologic agent remains unknown in over 75% of cases. this study prospectively examined the etiology of pneumonia among recruits at naval training center, san diego, california. recruits presenting with cough, fever, or shortness of breath and pulmonary infiltrates on chest x-ray were eligible for enrollment. a standard ...19947870317

validity of laboratory-based surveillance for detection of respiratory syncytial virus seasons.in this study, we validated the centers for disease control and prevention's use of a 10% threshold of median proportion of positive laboratory tests (median proportion positive (mpp)) to identify respiratory syncytial virus (rsv) seasons against a standard based on hospitalization claims. medicaid fee-for-service recipients under 2 years of age from california, florida, illinois, and texas (1999-2004), continuously eligible since birth, were categorized for each week as high-risk or low-risk wi ...201323479344
vaccination strategies against respiratory syncytial virus.respiratory syncytial virus (rsv) is the most common cause of us infant hospitalization. additionally, rsv is responsible for 10,000 deaths annually among the elderly across the united states, and accounts for nearly as many hospitalizations as influenza. currently, several rsv vaccine candidates are under development to target different age groups. to evaluate the potential effectiveness of age-specific vaccination strategies in averting rsv incidence, we developed a transmission model that int ...201627799521
clinical and laboratory features of pertussis in infants at the onset of a california epidemic.we report clinical characteristics and outcome of infants <3 months of age hospitalized with pertussis compared with viral respiratory infection (respiratory syncytial virus and influenza). patients with pertussis more often were afebrile, had more visits before admission, and had longer hospital stays. household coughing contacts were common.201121925678
a summer outbreak of human metapneumovirus infection in a long-term-care facility.human metapneumovirus (hmpv), a recently discovered paramyxovirus, is thought to be primarily a winter-spring pathogen affecting young children with a clinical presentation similar to that of respiratory syncytial virus. in june-july 2006, a respiratory outbreak in a long-term-care facility was reported to the local health department and investigated. surveillance identified 26 residents and 13 staff with acute respiratory illness; 8 residents (31%) developed radiographically confirmed pneumonia ...200717674312
