The epidemiology of acute adenolymphangitis due to lymphatic filariasis in northern Ghana.

A study to investigate the socioeconomic impact of lymphatic filariasis was conducted in a rural community in northern Ghana. The incidence, severity, and duration of acute adenolymphangitis (ADL), as identified by local terminologies and confirmed using World Health Organization diagnostic criteria, were investigated. Local terminologies were found to be highly specific and sensitive for diagnosing ADL (sensitivity = 0.978, specificity = 0.980). The incidence of ADL was 95.9 per 1,000 per annum among adults more than 10 years of age, being much higher in females than in males. Among those with elephantiasis and other chronic filarial symptoms, there was no clear relationship between the stage of chronic lymphedema and the incidence of ADL. The incidence of ADL was found to be closely related to the rainfall pattern. The design of the study, its findings, and the public health implications of the findings are discussed in this paper.
