Advisory Regarding Incidence of Glanders Disease in Delhi State
Recently cases of Glanders among equine population have been reported in Delhi State. Office of the Director, Animal Husbandry Unit, Delhi has informed that samples of 40 equines are found positive till date. Therefore it is advisable to strengthen surveillance to detect any suspected cases of Glanders disease among handlers and persons who come in close contact of equine population.
Lack of awareness among horse and donkey owners and general public can cause further spread of disease therefore strict implementation of ongoing policy comprising of health education and community awareness is must.
- Glanders is a infectious zoonotic disease primarily affecting horses, donkeys and mules. It is caused by Gram-negative bacterium, Burkholderia mallei. It is rare disease in humans with cases having occurred in veterinarians, other people working closely with horses, and laboratory workers handling the organism.
- Despite many reported cases of the disease in equines, no human case of glanders has been reported in India till date.
- Occupation exposure is the main risk factor to veterinarians, farmers, horse traders/ fanciers, laboratory workers, and other persons who are closely associated with equines or handling the organism.
- B. mallei is transmitted to humans through contact with tissues or body fluids of infected animals. The causative organism is present in nasal exudates and discharges form ulcerated skin of infected animals. The bacteria enter the body through cuts or abrasions in the skin and through mucosal surfaces such as the conjunctiva and nose. The infection may occur by inhaling infected aerosol dust. Animal-to-human and human-to-human transmission of glanders is rare.
- The clinical symptoms of glanders in humans are non- specific therefore accurate diagnosis and treatment is difficult. The symptoms in humans include low- grade fever and chills, malaise, fatigue, myalgias, backache, headache, rigors, chest pain and lymphadenopathy.
- Personnel in close contact with the diseased animals should follow high standard of personal safety, hygiene and strict antiseptic measures.
