CD40LG and infection: Univariable analysis of symptoms associated with infection of short evolution (RBT®, IgM and IgG ELISA® seropositive), long evolution (IgM ELISA® seronegative and RBT® and IgG ELISA® seropositive) and likely inactive infection (RBT® and IgM ELISA® seronegative and IgG ELISA® seropositive), identified a weak association between reported generalized aching and infection of short duration (OR = 4.8, 95% CI: 0.4–27.9, p = 0.103), and a suggestive stronger association between reported joint pain and infection of long duration (OR = 5.1, 95% CI: 0.9–33.3, p = 0.030).
