*Households were selected from among 35 leprosy patients encountered during the first visit (25 households, 14 with an anti–PGL-I–positive contact in the household and 11 without) and among students with results of anti–PGL-I serology (19 households, 11 with an anti–PGL-I–positive contact in the household and 8 without). PGL-I, phenolic glycolipid-I.
†Fisher exact test comparing case-patients and non–case-patients among those positive or negative for anti-PGL-I IgM revealed a statistically significant difference (p = 0.0280).
