You may develop kidney failure or breathing problems. Your blood may clot more than it should. This can keep the blood from flowing where it should in your body. RMSF may lead to lung problems, such as fluid buildup or swelling in and around your lungs. The bacteria can spread and infect organs or other parts of your body. RMSF may also cause swelling or damage in your liver, brain, or heart. RMSF may cause you to go into a coma if the infection is severe.
