The case fatality rate for leptospirosis is approximately 5%–15% among patients with severe illness. Among patients with severe pulmonary hemorrhagic syndrome, the case fatality rate can exceed 50%. Early treatment may decrease the severity and duration of disease.

What are the chances of surviving leptospirosis?

Can you fully recover from leptospirosis?

Yes, you can survive leptospirosis. Most cases of leptospirosis have no symptoms or have very mild symptoms that go away on their own. Only about 1% of people with leptospirosis get severely ill with Weil's syndrome. Weil's syndrome is often deadly if not treated or if you delay treatment.

How treatable is leptospirosis?

What is the toxic stage of leptospirosis?

The icteric phase of leptospirosis is classically known as Weil's disease. This is a severe infection, and the manifestations include fever, renal failure, jaundice, hemorrhage, and respiratory distress. The icteric phase may also involve the heart, CNS, and muscles.

What is the first symptom of leptospirosis?

Symptoms of Leptospirosis

Leptospirosis usually occurs in two phases: First phase (septicemic phase): About 5 to 14 days after infection occurs, fever, headache, sore throat, severe muscle aches in the calves and back, and chills occur suddenly. The eyes usually become very red on the third or fourth day.

How does leptospirosis exit the body?

The course of leptospirosis seem to be a process of continuous migration and transcytosis of pathogenic Leptospira species through mucosal and skin barriers to invade into hosts, blood vessel wall to enter or exit from bloodstream and renal tubule epithelium to discharge in urine.

Is leptospirosis terminal?

Overall, the prognosis of leptospirosis is good. Many people become infected and spontaneously recover without treatment. However, the prognosis worsens as the symptoms increase. People with Weil's disease may have a prognosis ranging from good to poor, depending on their response to treatment.

What is the prognosis for severe leptospirosis?

The case-fatality rate of severe leptospirosis rises above 50% [3]. The prognosis of leptospirosis depends on the severity, early diagnosis, and prompt intensive treatment. If not treated, the patient could develop kidney failure, meningitis, liver damage, and respiratory distress. In some cases, death occurs [4].

Once you reach this phase, the leptospira bacteria is now in your organs, especially your kidneys. The bacteria will show up in urine tests, and your body will build up protection (antibodies) against the bacteria.
