Human brucellosis in the Mid-West 2002-3.
Human brucellosis remains a serious public health issue in Ireland. Clinical notifications in the Mid-Western Area (HSE-MWA) underestimate the burden of illness and attendant morbidity in the region. The diagnosis of acute and chronic human brucellosis depends on the clinical evidence and the results from laboratory serological testing or culture on rare occasion. This study examined the clinical evidence behind locally defined serological "positives" in the HSE-MWA from 2002 to 2003. Ninety cases were detected in 2002 and 31 in 2003. While sampling bias is likely to be present, aspects of brucellosis in Ireland were confirmed. Middle-aged males were most commonly affected. The majority of cases were linked to farming or veterinary practice. Symptoms such as sweats, fever and weight loss were commonly associated with acute brucellosis infection while malaise was common in acute and chronic brucellosis. A clear definition of what is notifiable is needed. Surveillance systems must appreciate the importance of both clinical and laboratory evidence to classify confirmed or probable brucellosis as paired sera were not common. Public health authorities must follow-up the clinical aspects for accurate national statistics. General practitioners in the Mid-West appear to be vigilant regarding brucellosis in their patients. Regional zoonoses committees are useful in monitoring disease prevalence in human and animal populations without compromising confidentiality.
