Increases in mental health conditions have been documented among the general population and care workers since start of COVID-19 pandemic (1-3). Public might be at similar risk for negative consequences because prolonged demand responding to implementing an unprecedented vaccination campaign. The extent public during pandemic, however, is uncertain. A 2014 survey estimated that there were nearly 250,000 state local United States (4). To evaluate these workers, a nonprobability-based online...
An outbreak of Rift Valley fever (RVF) occurred in Kenya during November 2006 through March 2007. We characterized the magnitude disease surveillance and serosurveys, investigated contributing factors to enhance strategies for forecasting prevent or minimize impact future outbreaks. Of 700 suspected cases, 392 met probable confirmed case definitions; demographic data were available 340 (87%), including 90 (26.4%) deaths. Male cases more likely die than females, Case Fatality Rate Ratio 1.8...
A large Rift Valley fever (RVF) outbreak occurred in Kenya from December 2006 to March 2007. We conducted a study define risk factors associated with infection and severe disease. total of 861 individuals 424 households were enrolled. Two hundred two participants (23%) had serologic evidence acute RVF infection. Of these, 52 (26%) disease characterized by hemorrhagic manifestations or death. Independent for consuming handling products sick animals (odds ratio [OR] = 2.53, 95% confidence...
In August and September 2005, Hurricanes Katrina Rita caused breeches in the New Orleans, LA, levee system, resulting catastrophic flooding. The city remained flooded for several weeks, leading to extraordinary mold growth homes. To characterize potential risks of exposures, we measured airborne molds markers bacteria Orleans area October collected air samples from 5 mildly water-damaged houses, 15 moderately heavily 11 outdoor locations. filters were analyzed culturable fungi, spores,...
Mucormycosis is an invasive fungal infection with a high fatality rate. We investigated outbreak of mucormycosis in pediatric hospital to determine routes pathogen transmission from the environment and prevent additional infections.A case was defined as hospital-onset illness consistent mucormycosis, confirmed by culture or histopathology. Case-patient medical records were reviewed for clinical course exposure items locations within hospital. Environmental samples collected air surfaces....
CDC has updated its interim guidance for U.S. health care providers caring pregnant women with possible Zika virus exposure, to include the emerging data indicating that RNA can be detected prolonged periods in some women. To increase proportion of infection who receive a definitive diagnosis, recommends expanding real-time reverse transcription-polymerase chain reaction (rRT-PCR) testing. Possible exposures travel or residence an area active transmission, sex* partner traveled resides...
Damp building-related respiratory illnesses are an important public health issue.We compared three case groups defined by questionnaire responses [200 cases, 123 of the cases who met epidemiologic asthma definition, and 49 had current physician-diagnosed with post-occupancy onset] to a comparison group 152 asymptomatic employees in office building history water damage.We analyzed dust samples collected from floors chairs 323 comparisons for culturable fungi, ergosterol, endotoxin, cat dog...

Abstract The SARS-CoV-2 Delta variant, first identified in October 2020, quickly became the dominant variant worldwide. We used publicly available data to explore relationship between illness and death (peak case rates, case-fatality rates) selected predictors (percentage vaccinated, percentage of population >65 years, density, testing volume, index mitigation policies) 45 high-income countries during wave using rank-order correlation ordinal regression. During Delta-dominant period, most...
Approximately 8% of Rift Valley fever (RVF) cases develop severe disease, leading to hemorrhage, hepatitis, and/or encephalitis and resulting in up 50% deaths. A major obstacle the management RVF other viral hemorrhagic outbreaks that occur rural settings is inability rapidly identify such cases, with poor prognosis early enough allow for more-aggressive therapies. During an outbreak Kenya 2006 2007, we evaluated whether quantitative real-time reverse transcription-PCR (qRT-PCR) could be...
