During this stage, symptoms disappear, and the body starts to recover. Untreated patients could develop kidney damage, meningitis, liver failure, respiratory distress, and in some cases, may die. [1] In a typical infectious disease, the incubation period signifies the period taken by the multiplying organism to reach a threshold necessary to produce symptoms in the host. The level of faster the progression (Baer et al. This cosmopolitan disease is due to pathogenic agents of Leptospira interrogans species ( 2, 3 ). The terms "intrinsic incubation period" and "extrinsic incubation period" are used in vector-borne diseases. 2% of cases of animal rabies involve other wild animal species, Weil's disease is a complication of untreated leptospirosis and can be fatal.

The time from exposure to when symptoms appear can range from a few days to as long as six months. As a result, the prodromal stage may overlap with the incubation stage and the onset of illness. People with serious illness may require hospitalisation for treatment of complications such as kidney failure. The acute, septicemic phase lasts 7 days and presents as an acute febrile illness with symptoms including headache, which can be severe and include photophobia and retro-orbital pain; chills; myalgias, characteristically involving the calves and lower back; conjunctival suffusion, characteristic of leptospirosis but not occurring in all cases; nausea; vomiting; diarrhea; abdominal pain; cough; and rarely, a skin rash.
