Pathogenic leptospires rapidly invade the bloodstream after entry and spread throughout all sites in the body such as the central nervous system and kidneys. Virulent strains show chemotaxis toward hemoglobin as well as the ability to migrate through host tissues. Symptoms begin abruptly 2 to 20 days after infection and include fever, headache, and myalgia. The most common clinical syndrome is anicteric leptospirosis, which is a self-limiting illness consisting of a septicemic stage, with high fever and severe headache that lasts 3 to 7 days, followed by the immune stage. Symptoms associated with the immune stage are varied, but in general are milder than the septicemic stage. The hallmark of the immune stage is aseptic meningitis.
