BackgroundMyiasis due to Old World screw-worm fly, Chrysomya bezziana, is an important obligate zoonotic disease in the OIE-list of diseases and is found throughout much of Africa, the Indian subcontinent, southeast and east Asia. C. bezziana myiasis causes not only morbidity and death to animals and humans, but also economic losses in the livestock industries. Because of the aggressive and destructive nature of this disease in hosts, we initiated this study to provide a comprehensive understanding of human myiasis caused by C. bezziana.MethodsWe searched the databases in English (PubMed, Embase and African Index Medicus) and Chinese (CNKI, Wanfang, and Duxiu), and international government online reports to 6th February, 2019, to identify studies concerning C. bezziana. Another ten human cases in China and Papua New Guinea that our team had recorded were also included.ResultsWe retrieved 1,048 reports from which 202 studies were ultimately eligible for inclusion in the present descriptive analyses. Since the first human case due to C. bezziana was reported in 1909, we have summarized 291 cases and found that these cases often occurred in patients with poor hygiene, low socio-economic conditions, old age, and underlying diseases including infections, age-related diseases, and noninfectious chronic diseases. But C. bezziana myiasis appears largely neglected as a serious medical or veterinary condition, with human and animal cases only reported in 16 and 24 countries respectively, despite this fly species being recorded in 44 countries worldwide.ConclusionOur findings indicate that cryptic myiasis cases due to the obligate parasite, C. bezziana, are under-recognized. Through this study on C. bezziana etiology, clinical features, diagnosis, treatment, epidemiology, prevention and control, we call for more vigilance and awareness of the disease from governments, health authorities, clinicians, veterinary workers, nursing homes, and also the general public.

40Background 41 Myiasis due to Old World screw-worm fly, Chrysomya bezziana, is an important obligate 42 zoonotic disease in the OIE-list of diseases and is found throughout much of Africa, the 43 Indian subcontinent, southeast and east Asia. C. bezziana myiases cause not only 44 morbidity and death to animals and humans, but also economic losses in the livestock 45 industries. Because of the aggressive and destructive nature of this disease in hosts, we 46 initiated this study to provide a comprehensive understanding of human myiasis caused 47 by C. bezziana. 48 Methods 49We conducted a systematic search of the databases in English (PubMed, Embase and 50 African Index Medicus) and Chinese (CNKI, Wanfang, and Duxiu), and international 51 government online reports to 6 th February, 2019, to identify studies concerning 52 Chrysomya bezziana. Another ten human cases in China and Papua New Guinea that our 53 team had recorded were also included. 54 Results 55We retrieved 1,048 reports from which 202 studies were ultimately eligible for inclusion 56 in the present descriptive analyses. Since the first human case due to C. bezziana was 57 reported in 1909, we have summarized 291 cases and found that these cases often 58 occurred in poor hygiene, low socio-economic conditions, old age, and underlying 59 diseases including infections, age-related diseases, and noninfectious chronic diseases. 60 But C. bezziana myiasis appears largely neglected as a serious medical or veterinary 61 condition, with human and animal cases only reported in 16 and 24 countries respectively, 62 despite this fly species recorded as present in 44 countries worldwide. 63 Conclusion 64 Our findings indicate that cryptic myiasis cases due to the obligate parasite, C. bezziana, 65 are under-recognized. Through this in-depth study to clarify the knowledge of human C. 66 bezziana myiasis including its etiology, clinical features, diagnosis, treatment, 67 epidemiology, prevention and control, we call for more vigilance and awareness of the 68 disease from governments, health authorities, clinicians, veterinary workers, nursing 69 homes, and also the general public. 70 Author summary 71 Chrysomya bezziana larvae are characterized by feeding aggressively on the living 72 tissues and body fluids of the host. The nightmare-like feelings of patients suffering from 73 this myiasis, severe tissues and bones destruction, even death, and enormous economic 74 loss in the livestock industries have been described in the previous reports. But our 75 findings indicate that C. bezziana myiases still appear to be under-recognized as a serious 76 medical or veterinary condition throughout the world. Both in China and the world at 77 large, it is probable that C. bezziana distribution could be greater than currently reported. 78 For the first time, we have therefore systematically investigated human myiasis caused by 79 C. bezziana. Our study provides an opportunity for clinicians and health authorities to 80 gain a better understanding of this disease fr...

“…The species C. bezziana usually lay around 150-200 eggs and larvae come out in around a day. After hatching, larvae bury deep into tissues with help of their sharp hooks and get anchored by the intersegmental spines, scrapping away tissue and damaging small blood vessels.Tissue destruction may occur by the production of collagenase and proteolytic enzymes 11. Haemorrhage may be severe and causes tissue oedema.…”

Introduction: Myiasis is common in tropical regions, but now increasing incidence is seen in the west due to international travel. Otorhinolaryngological myiasis is uncommon and is seen in diabetics, alcoholics or patients unable in self-care.Objectives: To study presentations of otorhinolaryngological myiasis, identify associated risk factors and species of flies causing myiasis.Methods: Clinical findings and co-morbidities of 67 myiasis cases were noted. Maggots were identified, manually removed, and patients were managed with topical treatment, systemic ivermectin and antibiotics.Findings: Thirty-three nasal myiasis, 13 aural myiasis and 5 patients with oral myiasis were noted. Seven patients with head neck wounds myiasis and nine patients of tracheostome myiasis were recorded.Discussion: Warm humid climate of tropical regions is a major concern along with co-existing conditions like poor sanitation, alcoholism, psychiatric diseases and neuropathies. Hesitancy is seen in attendants and health care professionals to deal with myiasis.Conclusion: Awareness about risk factors is important in avoiding myiasis along with prompt treatment which reduces morbidity. Tracheostome myiasis is an under-documented entity rather than a rare presentation.Keywords: Myiasis, Ivermectin, screwworm, Chrysomya bezziana, Musca domestica, Lucilia sericata.Funding: None
