Chandigarh, April 9: A 58-year-old woman in Greece has become the subject of a landmark medical report after sneezing out late-stage sheep bot fly larvae. The rare infestation, which occurred after the woman worked near a field of sheep, represents the first documented case of the Oestrus ovis parasite reaching the pupation stage inside a human host.
The patient initially reported symptoms of sinus discomfort and a severe cough that lasted for nearly a month after being surrounded by a swarm of flies. The situation escalated in mid-October when she spontaneously sneezed out a visible “worm.” Doctors who examined the patient discovered that the larvae had not only survived but had also formed a puparium—the hard protective casing used for the fly’s final transformation.
Researchers maintained that the human sinus is generally too hostile for such development, yet the woman’s unique nasal structure appeared to provide the necessary conditions. “This case may represent a rare intersection of anatomy and parasite resilience,” a medical official asserted, noting that a bend in her nasal bone provided a protected pocket for the insects.
Following the surgical removal of the remaining parasites, the woman was treated with a course of decongestants and has fully regained her health. Health officials declared the event a significant anomaly, asserting that while such infections are unusual, they serve as a critical reminder of how specific physical factors can influence parasitic behavior in accidental hosts.
