Campylobacter jejuni is the most common enteric pathogen isolated from university and college students in the United States. During the fall and winter quarters of the 1983-1984 academic year, the authors conducted a case-control study at the University of Georgia, Athens, Georgia, to identify risk factors for C. jejuni enteritis. Students with diarrhea(More)
The morbidity and mortality associated with the 1980 heat wave in St Louis and Kansas City, Mo, were assessed retrospectively. Heat-related illness and deaths were identified by review of death certificates and hospital, emergency room, and medical examiners' records in the two cities. Data from the July 1980 heat wave were compared with data from July 1978(More)
OBJECTIVES To estimate the cost and cost-effectiveness of testing sexually transmitted disease (STD) clinic subgroups for antibodies to hepatitis C virus (HCV). METHODS HCV counseling, testing, and referral (CTR) costs were estimated using data from two STD clinics and the literature, and are reported in 2006 dollars. Effectiveness of HCV CTR was defined(More)
To determine whether the simultaneous, partial repeal of needle prescription and drug paraphernalia laws in Connecticut affected purchasing and usage of needles and syringes (syringes) by injecting-drug users (IDUs) and risk of needlestick injuries to police officers, we conducted two serial cross-sectional surveys with IDUs recruited in drug treatment(More)
We determined the cost of increasing access of injection drug users (IDUs) to sterile syringes and needles as an HIV prevention intervention in the United States and the cost per HIV infection averted by such a program. We considered a hypothetical cohort of 1 million active IDUs in the United States. Standard methods were used to estimate the cost and(More)
This study examines drug acquisition and multiperson use of paraphernalia, drugs, and needles/syringes. Ethnographers observed 54 injection episodes in which IDUs were linked by HIV risk behaviors, and developed a typology of higher-risk, lower-risk, and nonsharing-risk networks. Multiperson use of injection paraphernalia or drug solution occurred in most(More)

Among these, 16,235 (37%) were associated with prescription opioid analgesics (e.g., oxycodone and hydrocodone) and 8,257 (19%) with heroin. For many(More)
To identify risk factors associated with heatstroke, a case-control study in St Louis and Kansas City, Mo, was conducted during July and August 1980. Questionnaire data were gathered for 156 persons with heatstroke (severe heat illness with documented hyperthermia) and 462 control subjects matched by age, sex, and neighborhood of residence. A stepwise(More)
We reviewed 92 published and unpublished studies of the prevalence of infection with the human immunodeficiency virus (HIV) among intravenous drug users (IVDUs) in the United States. Human immunodeficiency virus seroprevalence among IVDUs in drug treatment programs in the United States ranged from 0% to 65%. Seroprevalence was highest in the Northeast (10%(More)
In Togo, the principal strategy for preventing death from malaria in children is prompt treatment of fever with antimalarial drugs. A household survey was conducted in a rural area of south-central Togo in which information was collected from mothers on the treatment received by 507 children under 5 years of age who, according to their mothers, had recently(More)
