Design: Cross-sectional Study.

Participants: Paired images from 192 eyes (189 participants) with diabetic retinopathy were included.

Halting a SARS-CoV-2 outbreak in a US Veterans Affairs nursing home.

A Veterans Affairs long term care facility on Long Island New York was confronted with a COVID-19 outbreak in late March to Mid-April 2020. Faced with a dwindling supply of PPE, the Infection Control team distributed supplies saved for a possible Ebola outbreak. A COVID unit was created within the nursing home facilitating the geographic isolation of cases; universal testing of residents and employees allowed for the implementation of proper quarantine measures.

Risk factors for meningococcal disease in students in grades 9-12.

Background: Meningococcal disease is a serious problem in adolescents, including high school students. Universal immunization of adolescents with meningococcal conjugate vaccine was recently recommended. We studied risk factors for meningococcal disease in students in grades 9-12.

Invasive group A streptococcal infection in older adults in long-term care facilities and the community, United States, 1998-2003.

Limited information exists on the incidence and characteristics of invasive group A streptococcal (GAS) infections among residents of long-term care facilities (LTCFs). We reviewed cases of invasive GAS infections occurring among persons > or =65 years of age identified through active, population-based surveillance from 1998 through 2003. We identified 1,762 invasive GAS cases among persons > or =65 years, including 1,662 with known residence type (LTCF or community).

The epidemiology of invasive group A streptococcal infection and potential vaccine implications: United States, 2000-2004.

Background: Invasive group A Streptococcus (GAS) infection causes significant morbidity and mortality in the United States. We report the current epidemiologic characteristics of invasive GAS infections and estimate the potential impact of a multivalent GAS vaccine.

Methods: From January 2000 through December 2004, we collected data from Centers for Disease Control and Prevention's Active Bacterial Core surveillance (ABCs), a population-based system operating at 10 US sites (2004 population, 29.

Adults with invasive pneumococcal disease: missed opportunities for vaccination.

Background: The pneumococcal polysaccharide vaccine (PPV) can prevent invasive pneumococcal disease (IPD) in the elderly and those with certain underlying illnesses. However, vaccine uptake remains suboptimal. Identification of missed opportunities for vaccination could guide new strategies for improving uptake.

Preventability of invasive pneumococcal disease and assessment of current polysaccharide vaccine recommendations for adults: United States, 2001-2003.

Unlabelled: BACKGROUND. To prevent Streptococcus pneumoniae infection among persons at highest risk for invasive pneumococcal disease (IPD), the pneumococcal polysaccharide vaccine (PPV) is currently recommended for persons >or=65 years old and persons 2-64 years old with certain underlying conditions. Policymakers have considered expanding recommendations for PPV to include persons who are 50-64 years old and additional populations at risk for IPD.

Gram-positive rod surveillance for early anthrax detection.

Connecticut established telephone-based gram-positive rod (GPR) reporting primarily to detect inhalational anthrax cases more quickly. From March to December 2003, annualized incidence of blood isolates was 21.3/100,000 persons; reports included 293 Corynebacterium spp.

Declining incidence of invasive Streptococcus pneumoniae infections among persons with AIDS in an era of highly active antiretroviral therapy, 1995-2000.

Background: Our goal was to describe trends in invasive pneumococcal disease incidence among persons with acquired immunodeficiency syndrome (AIDS) since the introduction of highly active antiretroviral therapy (HAART).

Methods: We used time-trend analysis of annual invasive pneumococcal disease incidence rates from a population-based, active surveillance system. Annual incidence rates were calculated for 5 July-June periods by use of data from San Francisco county, the 6-county Baltimore metropolitan area, and Connecticut.

A high-morbidity outbreak of methicillin-resistant Staphylococcus aureus among players on a college football team, facilitated by cosmetic body shaving and turf burns.

Background: Athletics-associated methicillin-resistant Staphylococcus aureus (MRSA) infections have become a high-profile national problem with substantial morbidity.

Methods: To investigate an MRSA outbreak involving a college football team, we conducted a retrospective cohort study of all 100 players. A case was defined as MRSA cellulitis or skin abscess diagnosed during the period of 6 August (the start of football camp) through 1 October 2003.

Aggregated antibiograms and monitoring of drug-resistant Streptococcus pneumoniae.

Community-specific antimicrobial susceptibility data may help monitor trends among drug-resistant Streptococcus pneumoniae and guide empiric therapy. Because active, population-based surveillance for invasive pneumococcal disease is accurate but resource intensive, we compared the proportion of penicillin-nonsusceptible isolates obtained from existing antibiograms, a less expensive system, to that obtained from 1 year of active surveillance for Georgia, Tennessee, California, Minnesota, Oregon, Maryland, Connecticut, and New York. For all sites, proportions of penicillin-nonsusceptible isolates from antibiograms were within 10 percentage points (median 3.

Utilization of extended-spectrum beta-lactamase (ESBL) detection systems in microbiology laboratories: survey of Connecticut hospitals from 1998-2002.

There has been recent concern raised over the detection, prevalence, and clinical implications of infection with Escherichia coli and Klebsiella spp. which produce extended-spectrum beta-lactamases (ESBLs). These enzymes hydrolyze beta-lactams including the cephalosporins (i.

Epidemiology of invasive group a streptococcus disease in the United States, 1995-1999.
