The main question\[s\] it aims to answer are:

* Testing whether preventive treatment with a single dose of doxylin at a dose of 200 mg is effective in preventing recurrent fever, and if so, at what rate * Checking the profile and rate of side effects in each one of the proposed treatment protocols Participants will be treated with standard treatment (5 days of doxycycline) or single dose doxycycline.
