Neither significant interactions nor multicollinearity was found among the variables included in our final multivariable models. environmental contamination. In the absence of a defined source of prior or continued contamination of Lake Springfield with pathogenic Leptospira, enhanced passive and active surveillance for symptoms and signs of illness of leptospirosis will be necessary to monitor the safety of recreational use of Lake Springfield. Reported cases of leptospirosis among European travelers most commonly have been acquired in Southeast Asia, and leptosporosis is the most common cause of life-threatening infection in travelers going to that region. species of pathogenic leptospires by PCR using two sets of rise in polyclonal Given that the current methods of freshwater testing cannot reliably furnish information that can be translated into effective public health measures, heightened awareness and development of sensitive, rapid, and inexpensive diagnostic assays for leptospirosis are needed. Wisconsin Community investigatio. participated in only the Wisconsin triathlon have demonstrated a In addition, serum samples obtained from athletes whose signs and symptoms met the definition of a suspected case of leptospirosis were also tested by an MAT, regardless of ELISA screening results. The cost of admission was 10 cents before 6 p.m. and 20 cents after, and even swimming attire and towels were provided, for 20 and 10 cents, respectively.

The environmental investigation consisted of sampling lake water for the presence of pathogenic leptospires, reviewing precipitation records and data from local lake management authorities, and testing animals for leptospirosis. In: Hausler WJ Jr, Sussman M, eds. For the month of June 1998, the average water pH, temperature, and raw turbidity were 8.07, 24.6°C, and 20.3 NTU, respectively, compared with values of 8.11, 23.6°C, and 16.3 NTU, respectively, for the months of June in 1994–1997. 2) a Springfield, Illinois Outbreak Investigation Team, Springfield Dept of Heavy rains that preceded the triathlon are likely to have increased leptospiral contamination of Lake Springfield.

Laboratory evidence for leptospirosis was defined as 1) a In addition, illness in Illinois-only case-patients To determine the pathogenic species of the genus Leptospira by PCR, the primers G1/G2 and B64-I/B64-II were used [8]. The lake is located in the heavily used agricultural area of Illinois and receives runoff from many local livestock farms. Oxford University Press is a department of the University of Oxford. Multivariable analysis of risk factors identified in a telephone survey of athletes with suspected or laboratory-confirmed leptospirosis who had competed in a triathlon in Springfield, Illinois, on 21 June 1998. specimens were obtained from the 90 athletes whose illness met the local health had an had acute-phase serum specimens tested at CDC by ELISA. In addition, results are not available until long after treatment decisions have been made. indicates Athletes who resided in 44 US states, Canada, and Austria were contacted by telephone and were also queried, by use of a standardized questionnaire, about presence of a flulike illness, triathlon preparation activities, use of various competition-related products, sources of food and water ingested during the triathlon, quantity of lake water ingested during the triathlon swimming event, presence of abrasions, and triathlon participation before or after 21 June 1998. We defined a “laboratory-confirmed case” of leptospirosis as a suspected case for which 1 or more positive results were obtained by use of the following laboratory tests: ELISA, MAT, culture, or immunohistochemical (IHC) analysis of tissue [6, 7]. Active surveillance involved contacting physicians and infection control nurses from the emergency departments of all 3 area hospitals and requesting that persons with possible cases of leptospirosis be referred to the SDPH. 6th ed. these Empiric therapy with doxycycline, ampicillin, amoxicillin, or penicillin [11] should be considered for patients suspected of having leptospirosis after exposure to any outdoor freshwater source. of these persons were positive by ELISA.

This not only reflects the lack of familiarity of US health care providers with the symptoms and epidemiology of leptospirosis but, also, a lack of familiarity with the morbidity associated with this infection. Leptospirosis is spread mainly by contact with water or soil contaminated by the urine of infected animals. London, that Presumably, flooding elevates the water table, allowing the soil to be saturated by subsurface leptospires, preventing the evaporation of contaminated animal urine and fostering the passage and survival of leptospires in surface waters [18]. years); On July 24, the Springfield and the Illinois departments of health issued a precautionary advisory not to swim, water ski, or use personal watercraft at Lake Springfield.
