Synopsis
CAPC Recommends Maintain companion animals on a year-round ectoparasite control product. Monitor wounds and any suspect fly larvae found on wounds of companion animals should be identified to rule out NWS infestation.
Species
Feline Canine Cochliomyia hominivorax - New World Screwworm Cochliomyia hominivorax 3rd instar larva Cochliomyia hominivorax 3rd lnstar larva - anterior end Cochliomyia hominivorax 3rd instar larva - tracheal trunks NWS adult fly
Prevalence
Cochliomyia hominivorax was historically found throughout the southern United States, Central America, and the northern countries of South America. Eradication efforts eliminated C. hominivorax from the United States, Mexico, Central America, and several Caribbean islands.
Diagnosis
New World screwworm (NWS) infestation is typically associated with the presence of a pre-existing wound, such as the naval of newborn animals, open cuts, open insect/tick bite wounds, etc.; however, infestation around mucous membranes or skin fold areas may also occur. Wounds may be malodorous and produce suppurative or serosanguinous discharge.
Treatment
Do not initiate treatment before contacting appropriate state and federal agencies. Treatment of NWS infestations involves removing visible eggs and larvae from the wound.
Control and Prevention
NWS was eradicated in the United States in the 1950’s and 60’s, with only sporadic cases since. The mainstay of preventing NWS re-entry to the United States is sanitary and medical prophylaxis.
