Update on sarcocystis-like illness after visiting
An outbreak of muscular sarcocystis-like illness has been evidenced since summer 2011 among travelers after visiting
Starting in summer 2011, 35 patients were identified by early 2012 and travelled there mostly during July and August 2011. The epidemic is currently ongoing, with a 2nd wave of 65 reported new diseased travelers returning since summer 2012. A cluster of 12 patients returning from Peninsular Malaysia since late August 2012 were seen and followed in
In the period of September-October 2012, 12 patients (7 male, 5 female; aged 11-46 years) were referred to the Division of tropical medicine, University Hospital Center, Bordeaux, France, with febrile myalgia, unexplained blood eosinophilia, elevated CPK levels, and negative trichinellosis serology.
Cases spent their vacation from 26 Jul to 25 Aug 2012 on the east coast of peninsular
Three cases experienced febrile illness for more than 14 days. 2 patients had suffered from diarrhoea and extensive maculo-papular rash. A muscle biopsy from one patient revealed intense myositis, but no intramuscular cysts. Half of patients healed using usual antalgic treatments. 6 patients were given empirically albendazole 400 mg twice a day for 7 days and oral prednisone (0.5 mg/kg/day) for 3 days tapered over 2 days. 6 weeks later, 4 patients have still not recovered and were experiencing prolonged asthenia and myalgia. The patients were effectively treated with additional prednisone 0.5 mg/kg/day for 5 days and decreasing dosage over 14 days. By February 2012, one patient relapsed with musculoskeletal complaints. All patients were reported to GeoSentinel for lab and epidemiological investigation, and TropNet was informed.
