Symptoms often go away briefly after about 3-4 days. Stage 2 (remission): Fever and other symptoms go away. Most people will recover at this stage, but others may get worse within 24 hours.Stage 3 (intoxication): Problems with many organs occur. This may include heart, liver, and kidney failure, bleeding disorders, seizures, coma, and delirium.
