clinical features
Last reviewed 01/2018
Clinical features occur after an incubation period of 2 to 10 days, and are as follows:
- presenting features are fever, headache, rigors
- may progress to develop jaundice and hepatosplenomegaly
- petichial rash may occur
- crises with tachycardia and fevers occur
- after the crises the patient becomes hypotensive.
- the condition may relapse but crises are less severe than at onset
- ultimately it may be fatal
The louse-borne, epidemic form has a longer incubation period, longer periods of fever but fewer relapses.
