Introduction: Eosinophilia and anemia are very common hematological alterations in the tropics but population-based studies scrutinizing their value for diagnosing parasitic infections are rare. Methodology: A cross-sectional study was conducted in a rural district in northeast Brazil where parasitic infections are common. Stool and blood samples were collected and individuals were clinically examined for the presence of ectoparasites. Results: In total, 874 individuals were examined. Infection with intestinal helminths occurred in 70% (95% CI 67 -75), infestation with ectoparasites in 45% (95% CI 42 -49) and co-infection with both helminths and ectoparasites was found in 33% (95% CI 29% -36%) of all inhabitants. Eosinophil counts ranged from 40/µl to 13.800/µl (median: 900/µl). Haemoglobin levels ranged from 4.8 g/dl to 16.8 g/dl (median: 12.5 g/dl), and anemia was present in 24% of the participants. Leukocytosis was found in 13%, eosinophilia in 74%, and hypereosinophilia in 44% of the participants. Eosinophilia was more pronounced in individuals co-infected with intestinal helminths and ectoparasites (p < 0.001) and correctly predicted parasitic infection in 87% (95% CI 84%-90.7%) of all cases. Conclusions: Eosinophilia is strongly associated with the presence of intestinal helminthiases and accentuated by co-infestation with ectoparasites. Our study confirms in a population with high prevalence of intestinal helminthiases and ectoparasites that eosinophilia can be used to accurately diagnose current parasitic infection and initiate treatment.

“…Algengt er að kláðinn versni á nóttunni og valdi því að sjúklingur eigi erfitt með svefn, líkt og átti sér stað í þessu tilfelli. 9 Vitað er um tilfelli þar sem kláðinn kom ekki fram fyrr en nokkrum mánuðum eftir útsetningu. 10 Lirfan getur skriðið allt frá nokkrum millimetrum á dag til tveggja sentimetra á dag.…”

“…The most commonly affected sites are those in close contact with the soil (Araújo et al, 2000). A recent case series of CLM in Brazil, for example, showed that cutaneous lesions are more frequently observed on the feet (73.3%), buttocks (14.7%), genital and inguinal areas (8.0%), legs (2.7%), and hands (1.3%) (Jackson et al, 2006). Other sites, such as the face (Bouchad et al, 2000) and the scalp (Guimarães et al, 1999), are rarely affected.…”
