title: Human trichinosis in remotes of Uttarakhand, India.
abstract: Trichinosis is a parasitic zoonosis caused by ingestion of infected meat containing larvae of Trichinella, more prevalent in developing countries. Although infection with Trichinella is globally distributed, it has been documented only rarely in India. The reports are available where Trichinella larvae were found from animals in India but, to our knowledge, only one human case has been reported from India (Punjab), so far. This is the first report of small multiple outbreaks of human trichinosis in India (2009-2011). Epidemiological, clinical, and laboratory findings of trichinosis patients belonging to remote areas of Uttarakhand were analyzed retrospectively and prospectively. Patients belonged to remote areas of Garhwal, Uttarakhand, 77.78% were male, and 22.22% were female. The age of patients ranged from 9-55 yrs. History of eating meat of wild boar was given by all (100%). The signs and symptoms of the patients varied even after intake of same diet, and included generalized weakness/malaise, myalgia, fever, gastrointestinal symptoms, facial/periorbital edema, subconjunctival hemorrhages, retinal hemorrhages, muscle atrophy, and dyspnea. Laboratory investigations revealed eosinophilia, leukocytosis, creatine phosphokinase (CPK) and serum glutamic oxaloacetic transaminase (SGOT) elevation in 100%, 88.89%, 50% and 16.67%, respectively. Muscle biopsies revealed larvae in 27.78%. One patient expired while others improved. The prevalence of trichinosis is likely to be underestimated. The aim of this study is to emphasize on the magnitude of the problem, to educate people, especially in the affected areas about this health hazard and help implementation of epidemiological studies and preventive measures.
