The prevalence of Wuchereria bancrofti antigenaemia determined in 353 subjects in Matara, Sri Lanka by Og4C3 ELISA was 20.7%. Positive rates obtained with the same subjects by 1 ml Nuclepore filtration and 60 µl thick blood smear were 11.3% and 7.9%, respectively. Antigen levels were positively associated with microfilaria counts. Two‐thirds of antigen‐positive and microfilaria‐negative (Ag+/Mf‐) individuals were > 25‐year‐old, but younger age groups (≤ 25‐year‐old) tended to have proportionally more Ag+/Mf‐ cases. Possible origins of the Ag+/Mf‐ status are discussed.
