The numbers of reported cases of coccidioidomycosis in Arizona and California have risen dramatically over the past decade, with a 97.8% and 91.1% increase in incidence rates from 2001 to 2006 in the two states, respectively. Of those cases with reported race/ethnicity information, Black/African Americans in Arizona and Hispanics and African/Americans in(More)
Coccidioidomycosis or Valley Fever is a fungal disease that occurs primarily in the southwestern United States. Of the estimated 150,000 U. S. coccidioidomycosis infections per year, approximately 60% occur in Arizona, making this state the focal point for investigation of the disease. In this manuscript, we describe the epidemiology of coccidioidomycosis(More)
BACKGROUND On 12 February 2008, an infected Swiss traveler visited hospital A in Tucson, Arizona, and initiated a predominantly health care-associated measles outbreak involving 14 cases. We investigated risk factors that might have contributed to health care-associated transmission and assessed outbreak-associated hospital costs. METHODS Epidemiologic(More)
Coccidioidomycosis is endemic to the southwestern United States; 60% of nationally reported cases occur in Arizona. Although the Council of State and Territorial Epidemiologists case definition for coccidioidomycosis requires laboratory and clinical criteria, Arizona uses only laboratory criteria. To validate this case definition and characterize the(More)
OBJECTIVE To examine the impact of a minimum interval schedule for administering diphtheria and tetanus toxoids and acellular pertussis vaccine (DTaP) in infants during a statewide pertussis outbreak on receipt of inactivated polio vaccine (IPV) and pneumococcal conjugate vaccine (PCV). DESIGN Retrospective cohort study using the state immunization(More)
Coccidioidomycosis is a common cause of community-acquired pneumonia (CAP) in disease-endemic areas. Because testing rates influence interpretation of reportable-disease data and quality of CAP patient care, we determined the proportion of CAP patients who were tested for Coccidioides spp., identified testing predictors, and determined the proportion of(More)
An outbreak of Salmonella serotype Montevideo infections associated with multiple locations of restaurant chain A in Phoenix, AZ, was identified in July 2008. One infected individual reported eating at a chain A catered luncheon where others fell ill; we conducted a cohort study among attendees to identify the vehicle. Food and environmental samples(More)
Coccidioidomycosis presumably causes ≤ 33% of community-acquired pneumonias cases, although < 15% of the patients are tested for coccidioidomycosis. We assessed healthcare providers' knowledge, attitudes, and practices regarding coccidioidomycosis diagnosis and treatment in Arizona. A survey was mailed to 7,608 eligible healthcare providers licensed by the(More)
Acinetobacter spp. are a diverse group of Gram-negative bacteria frequently implicated in nosocomial infections. Genotypic methods have been instrumental in studying Acinetobacter, but few offer high resolution, rapid turnaround time, technical ease and high inter-laboratory reproducibility, which has hampered understanding of disease incidence,(More)
An outbreak investigation identified 15 pertussis cases among 5 infants and 10 healthcare professionals at 1 hospital's neonatal intensive care unit (NICU). The cost of the outbreak to this hospital was $97 745. Heightened awareness of pertussis in NICUs is key to preventing healthcare-associated spread and minimizing outbreak-control-related costs.(More)
