Review
Myiasis is a common travel-associated dermatosis. Travelers to many parts of Central and South America are susceptible to infestation by Dermatobia hominis. Despite the common name of human botfly, D hominis infests a broad range of mammals and is a severe pest to economically important farm animals in endemic regions. The adult female does not lay the eggs on the host. Instead, the adult female infests hosts indirectly by using blood-feeding arthropods to serve as phoretic vectors to transport the eggs. We present a patient who acquired Dermatobia when bitten by a day-active mosquito during a visit to Guatemala. He had a locally painful, firm furuncular lesion with a central pore that drained serosanguineous exudates. The patient applied an occlusive ointment and recovered the larva after it emerged. In this report we discuss the life cycle of D hominis, the differential diagnosis, and therapeutic approaches.

In 1999, among 164 randomly selected Dutch sheep farmers, a questionnaire was carried out to estimate the prevalence of myiasis in sheep and to investigate factors associated with the occurrence of myiasis. The total number of sheep and/or lambs on the reference date 1 August 1999 was 12,200: 5243 ewes, 225 rams, 3393 ewe- and 3339 ram lambs. On 86 (52.4%) of the farms 349 (2.9%) of all sheep and/or lambs contracted myiasis, of which two died. Myiasis was seen significantly more frequently on farms with over 25 ewes compared to smaller farms. Cases of myiasis were detected from April to September, with a peak (47.1%) in August. Occurrence of myiasis was most frequently associated with hot and humid weather and was mainly observed (69.1%) in the area around the tail.Ewes and ewe lambs had significantly more myiasis when compared with rams and ram lambs. There was no relationship with tail docking, with breed, with the time of shearing, with the kind of soil (clay, sand, etc.), with the environment (bush, trees, water, etc.), with the type of treatment (pour on, dipping, spraying), the used insecticides (synthetic pyrethroïds, diazinon, cyromazin, etc.), the number of preventive treatments, the time of treatment or the number of observations on the herd (once a day, once a week, etc.).

Review
PURPOSE
To review 54 cases of human myiasis in China reported from 1995-2001 in order to characterize the current epidemic situation.
DATE SOURCES
All reference data originated from some Chinese literature in Chinese medical journals. Twenty-four short reports published from 1995-2001 were selected according to the stated purpose. Due to the varied outcomes of myiasis at different sites in the body, the present paper is divided into 7 types of infection: ocular, nasal cavity, external auricular, cutaneous, gastrointestinal, urogenital, and traumatic myiasis.
RESULTS
Of these 54 selected cases of myiasis in China from 1995-2001, hypodermic myiasis (31 patients) and ocular myiasis (12 patients) were the most common, comprising 43 cases (80%). The cases were equally distributed amongst both genders. Furthermore, most of the infected were children and infants, totaling 39 cases, or 72%. The regional distribution of myiasis was widespread throughout the sixteen provinces and autonomous regions in question.
CONCLUSIONS
Although not always reported, myiasis is a common zoonotic parasitosis occurring in most of China's territories. Due to its prevalence, preventive measures for myiasis are urgently needed.

Review
Rat-tailed larvae of the syrphid species Palpada scutellaris (Fabricius, 1805) are documented causing an enteric human myiasis in Costa Rica. This is the first time that the genus Palpada is recorded as a human myiasis agent. We report a 68-year-old woman with intestinal pain and bloody diarrhea with several live Palpada larvae present in the stool. Using molecular techniques (DNA barcodes) and both electronic and optical microscopy to study the external morphology, the preimaginal stages of the fly were unambiguously identified. An identification key to all syrphid genera actually known as agents of human and animal myiases is provided for larvae, puparia, and adults. Moreover, a critical world review of more than 100 references of Syrphidae as myiasis agents is also given, with emphasis on the species with rat-tailed larvae.

Human myiasis may be caused by several species of dipterous larvae. It is widespread in the tropics and subtropics particularly in Africa and the Americas and can occur in other parts of the world although less frequently. Larval infestation mostly affects the skin but can also involve wounds, bones, intestines and body cavities. Diagnosis is mainly clinical. The rule of treatment is to remove the larvae and treat any associated infection. Frequent international travel, immigration and rising global trade increase the likelihood of imported infestations. It is therefore vital that physicians in non-endemic areas are aware of clinical symptoms, exposure and presentation of this condition, as early recognition would prevent any costly, inappropriate treatments or complications. We report a case of imported human myiasis and present a literature review of human myiasis.
