This lesion may be large, almost up to an inch across. Over the next 2 to 3 days, a rash develops with many small versions of the initial lesion and resembling the chickenpox rash in nature. These lesions clear up within a week. Sanitary measures, especially with regard to control of mice and their parasites, will prevent spread of rickettsialpox.
Medications used include tetracycline and doxycycline.
Full recovery is expected. There are usually no complications if the disorder is treated. Call your health care provider if your child has symptoms suggestive of rickettsialpox. This is a magnified photograph of a mite.
