Rocky Mountain Spotted Fever
A mother brought her 9 year old son into their doctor’s office. Her son had been experiencing a fever and general malaise for the last three days. She suspected he might be getting the flu.

Since the boy was probably bitten by a bug (tick) and his platelets were low. Blood serologies were ordered to identify the presence of antibodies. Rickettsia rickettsii is suspected. He starts the boy on IV antibodies of doxycycline.
Tests confirm the bacterium Rickettsia rickettssii. The boy is treated in the hospital due to how many days the child had been exposed to the bacterium. The boy probably came in contact with the bacterium after being bitten by a tick while on the family’s camping trip.
