RICKETTSIAL DISEASES

Rickettsial diseases are caused by rickettsial bacteria or tick bites, which are microorganisms that live solely within cells. Rickettsial diseases range from self-limiting minor conditions to life-threatening infections, mainly if complications occur. The disease is triggered by microorganisms destroying blood vessels in numerous organs and tissues. In addition, several organs and tissues can be affected in severe instances.

TYPES

Rickettsial diseases are classified into three types:

Spotted fever group

  • Oriental spotted fever
  • Australian tick typhus
  • Siberian tick typhus
  • Boutonneuse fever
  • Rickettsialpox
  • Rocky Mountain spotted fever

Typhus group

  • Murine typhus
  • Brill-Zinsser and Louse-borne typhus disease
  • Rickettsia Typhi

Others

SYMPTOMS

The symptoms of rickettsial diseases somewhat vary based on their type. However, most people affected by this disease exhibit the following symptoms.

  • Fever
  • Aching Muscles
  • Headache
  • Malaise
  • Widespread Rashes
  • Nausea
  • Vomiting

DIAGNOSIS

Serology is the gold standard for verifying rickettsial diseases. This is a blood test that looks for antibodies to rickettsial antigens. A physician’s examination and biopsy of the rash may also be performed. Physicians also asked the following questions since rickettsiae bacteria are spread by lice, fleas, mites, and ticks.

  • If they’ve visited a region where these illnesses are widespread.
  • If they were bit by a tick or other kind of vector.

Having bitten is a helpful indicator, especially in locations where frequent rickettsial or a similar illness is common. Most individuals, however, do not remember such a bite. If physicians suspected Q fever, they could also inquire whether patients were on or around a farm since the bacteria that produce this sickness live in goats, sheep, and cattle.

TREATMENT

Antibiotics must be used to manage all rickettsial diseases. To be most beneficial and give the best results, they must be begun early during the first week of sickness.

  • Doxycycline- the first choice medicine
  • Chloramphenicol- alternative medicine

Moreover, supportive treatment with electrolytes and hydration control is crucial in managing individuals with rickettsial diseases, especially if there are indicators of blood coagulation difficulties, electrolyte abnormalities, or low blood pressure. Rickettsialpox is a self-limiting illness, and medicines cannot be required in some instances, mainly if the disease is minor or the patient is a baby or young kid.
