The spotted fever rickettsia, Rickettsia helvetica, is mostly reported to present a flu-like self-limiting disease. [ncbi.nlm.nih.gov]

• Fever

  PATHOGENESIS: Typhus, spotted fever and trench fever are transmitted via arthropod vectors; Q fever is acquired via inhalation or ingestion of contaminated milk or food. [myplace.frontier.com]

  A 17-year-old otherwise healthy girl was admitted to Department of Zoonotic and Tropical Diseases because of fever, eschar and rash. [ncbi.nlm.nih.gov]

  On day 7 after the second onset of fever, the patient was able to work but still felt ill and had a slight fever (37.6°C). [doi.org]

  Regarding the typhus group rickettsioses, there is clinical or serological evidence of Rickettsia prowazekii in Guatemala, Rickettsia typhi in Panama, Guatemala, and Costa Rica and unidentified species of the typhus group in El Salvador. [dovepress.com]

• Vomiting

  Other symptoms are general symptoms common with other types of infections such as vomiting, diarrhea, and abdominal pain. [web.uconn.edu]

  Symptoms (incubation time: 5-7 days): Fever, nausea, vomiting, severe headache, lymphadenitis, exanthema. [arminlabs.com]

  Patients infected with R. rickettsii generally have nonspecific symptoms including fever, nausea, vomiting, muscle pain, lack of appetite, and severe headache after an incubation period about 5-10 days following an infected tick bite. [microbewiki.kenyon.edu]

  Patient 2: A 20-year-old male in contact with a dog presented with a 6-day history of fever up to 39.5°C, dry cough, arthralgias, myalgias, headache, sweating and vomiting. He showed a macular rash on the trunk and upper limbs without itching. [elsevier.es]

• Nausea

  Symptoms (incubation time: 5-7 days): Fever, nausea, vomiting, severe headache, lymphadenitis, exanthema. [arminlabs.com]

  Experience of the self-reported symptoms nausea (p = 0.006) and radiating pain (p = 0.041) was more common among those with recent, current or probable infection compared to those who did not seroconvert. [ncbi.nlm.nih.gov]

  Patients infected with R. rickettsii generally have nonspecific symptoms including fever, nausea, vomiting, muscle pain, lack of appetite, and severe headache after an incubation period about 5-10 days following an infected tick bite. [microbewiki.kenyon.edu]

• Skin Rash

  Most rickettisal species produce a constellation of high fever, headaches, and skin rash. Most Rickettsial species are transmitted by arthropod vectors during blood meals. Treatment for all Rickettsial diseases is doxycycline or chloramphenicol. [pathwaymedicine.org]

  This is followed by dissemination via the vascular system producing vasculitis and a skin rash. These lesions may become necrotic. [myplace.frontier.com]

  Rash (small, tiny bumps on the skin) normally starts on the limbs and may eventually involve the whole body. [tickbites.net]

  Some other conditions that may be confused with tick bite fever are infection with Neisseria meningitidis (the meningococcus, which causes meningitis and a skin rash), measles and German measles. [health24.com]

• Eruptions

  Several days after an eschar appears, the following can develop: Fever Headache Rash (sparse maculopapular or papulovesicular eruptions on the trunk and extremities) Muscle aches NOTE: R. parkeri rickettsiosis can be difficult to distinguish from RMSF [cdc.gov]

  The infection tends to be moderate to severe and a generalised maculopapular eruption is seen. The systemic features of epidemic louse-borne typhus include neurological symptoms (eg, deafness and delirium) and abdominal pain. [dermnetnz.org]

  The rash is a diffuse macular (featuring elevated discoloration) rash, is most prominent on wrists and ankles, which will usually erupt three or four days after the onset of fever. [web.uconn.edu]

• Suggestibility

  These data suggest that NLRP3 inflammasome plays a role in host control of bacteria in vivo in a tissue-specific manner. [ncbi.nlm.nih.gov]

• Headache

  Clinical features are generally mild, characterized by eschar, fever, headache, malaise and lymphadenopathy. Antigenic similarity among rickettsiae leads to cross-reactive antibody responses; definitive diagnosis requires molecular methods. [ncbi.nlm.nih.gov]

  She was febrile (38.5°C) and reported headache, nausea, and abdominal pain. She had no eschar or rash. [doi.org]

  Usually a fever accompanies the appearance of the eschar along with other discomforts such as headache. Lymph nodes near the site usually swell. [tickbites.net]
