What are the cause and effect of Leptospirosis?

  • Leptospirosiscommonly known as rat fever or Andaman hemorrhagic fever, a bacterial infection caused by ‘spirochete’, is naturally carried by more than a dozen species of rodents, wildlife and domestic animals.
  • Dogs, cattle and rabbits also transmit the infection, Rodents have an enormous ability to excrete large number of leptospirae in the urine, which is the main source of contamination incriminating human and animal leptospirosis.
  • Infection can also occur through aborted fetuses, afterbirth or uterine discharges of cattle or the semen of an infected bull.
  • Humans can become infected by all these animals, and especially if mucous membranes and/or skin is damaged, the bacteria get an opportunity to invade.
  • Clinically, patients may suffer from non-specific symptoms like fever, body ache, vomiting, redness of eyes, cough and chest pain.

  • Once the diagnosis is established, immediate treatment should be started.
  •  A medicine named Doxycycline 100 mg should be prescribed twice a day for seven days and ampicillin/amoxicillin should be prescribed to children and pregnant and lactating women for seven days.
  • Severely ill patients need an aggressive treatment format with parenteral therapy.
  • Hygienic practices including avoiding direct and indirect human contact with animal urine are recommended as preventive measures.
  • Doxycycline can also be given as a preventive drug in the dose of 200mg per week maximally for eight weeks, to those exposed and at great risk, especially in a flood situation.
