Evidence of locally acquired Spotted Fever Group Rickettsiosis in Southeast Texas, 2008-2016.
We identified six paediatric case-patients from southeast Texas diagnosed with confirmed or probable Spotted Fever Group Rickettsiosis (SFGR) between 2008 and 2016. Only one case had a history of travel to an endemic area. Clinical and laboratory findings strongly suggest locally acquired Rocky Mountain Spotted Fever in one Houston patient. Public health reporting of SFGR is critical for monitoring emergence in nonendemic regions.
