Pegava groznica na Rocky Mountain

A rare, life-threatening infectious disease caused by the tick-borne bacterium *Rickettsia rickettsii* is characterized by sudden fever, malaise, and intense headaches. Symptoms often include muscle pain, loss of appetite, nausea, vomiting, abdominal pain, and light sensitivity. Typically, 2-5 days after the fever begins, a rash emerges, starting as erythematous, blanching or non-blanching maculopapular spots with petechiae on the wrists and ankles, then spreading to the palms, soles, arms, legs, and trunk. Additional symptoms may include conjunctivitis, mucosal ulcers, post-inflammatory hyperpigmentation, jaundice, pneumonia, enlarged liver, kidney failure, meningismus, amnesia, swollen optic disc, and blockage of the eye's arteries.
