Nosocomial myiasis: Report of two cases during hospitalization in intensive care units (ICUs)

Background: Most cases of human myiasis are seen in the tropical and subtropical countries. Myiasis is the infestation of live humans and vertebrate animals with larvae of flies, which feed on the host's dead or living tissue. Nosocomial myiasis is a type of infestation that requires admission to the hospital. Cases Report: Here, we report the first cases of nosocomial myiasis in two patients admitted to the ICU caused by Lucilia sericata from Alborz Province in Iran between September and December ۲۰۲۱. The first report describes a case of nosocomial myiasis of a ۵۵-year-old female who was admitted to the adult intensive care unit due to acute intracerebral hemorrhage. Ten days after admission, the nurses emerged eighty mobile larvae from the external auditory canal and patient hair. The maggots were submitted to the parasitology laboratory for identification and were found to be Lucilia sericata larvae. The second case, a ۵۸-year-old female patient was admitted to the surgery department for heart valve replacements. One week after, many maggots came out of her nose and mouth was identified as the common green bottle fly. Conclusion: These reports highlight the need to train medical and paramedical staff, as well as establish and implement health protocols in hospitals to prevent nosocomial myiasis and improvement of general sanitation. To the best of our knowledge, this is the first report of nosocomial myiasis in the Alborz Province, Iran.
