Kerala man infected with rare bacterial disease: What to know about murine typhus

A 75-year-old man from Kerala has been diagnosed with murine typhus, a rare bacterial disease, after traveling to Vietnam and Cambodia. Following his return, he sought medical help on September 8, reporting symptoms such as body pain and fatigue.

Initial tests for diseases transmitted by rats and fleas yielded inconclusive results, although a decline in his liver and kidney functions was noted.

Given his travel history, doctors suspected murine typhus, marking the first recorded case of this disease in the state.

Murine Typhus is a disease caused by the bacterium Rickettsia typhi, which is primarily transmitted to humans through fleas that infest rodents, especially rats. It is classified as a form of typhus fever and is particularly prevalent in urban areas where there are large populations of rats and associated fleas.

Key Information About Murine Typhus:

• Transmission: The disease is primarily spread through fleas that infest rodents, particularly rats. When these fleas bite humans or their feces come into contact with broken skin, the bacteria can enter the bloodstream.

  
  

• Symptoms: Common symptoms include fever, chills, headache, muscle aches, and a characteristic rash that typically starts on the trunk.

  
  

• Diagnosis: Diagnosis often involves considering travel history and conducting serological tests. In this case, the patient's symptoms and travel history were pivotal for diagnosis.

  
  

• Treatment: Murine typhus is typically treated with antibiotics, with doxycycline being the most commonly prescribed medication. Early intervention can help mitigate severe complications.

  
  

• Prevention: Effective prevention focuses on controlling rodent populations and minimizing contact with fleas. This includes maintaining cleanliness, using insecticides, and taking measures to prevent infestations.
