Woman sneezes out maggots after fly larvae get trapped in her deviated septum is currently attracting attention in the technology world.
Experts believe this development may influence how digital platforms evolve
over the coming years.
A 58-year-old woman in Greece appears to hold the record for growing a parasitic sheep bot fly in her nose the longest, almost creating a snot rocket that could literally fly.
Usually, when the sheep bot fly accidentally nosedives into a human’s schnoz, the first-stage larvae they deliver don’t actually develop. In contrast, in its normal target—a sheep’s nose— the larvae would move up into the sinuses, feed, grow, and molt into second- and third-stage larvae. From there, the flies (Oestrus ovis) drip from the nose onto the ground, burrow into the soil, pupate, and emerge as adult flies.
For a long time, experts thought that the flies couldn’t complete their advancement in humans beyond the first larval stage. But a few human cases have been reported in recent decades involving the second- and third-stage larvae. The woman’s case, reported in the Journal of Emerging Infectious Diseases by a medical entomologist and colleagues, goes the furthest yet, finding pupa and a puparium—the hard casing of a pupa—in the woman’s nose.
In the report, the experts note that the woman worked outdoors in an area of a Greek island close to a field with grazing sheep. On a hot and dry September day, she recalled a swarm of flies bombarding her face. About a week later, she had facial pain and then developed a cough over the next two to three weeks. Those were her only symptoms until October 15, when she sneezed and reported that “worms” came out of her nose. They were, in fact, late-stage sheep bot fly larvae.
She had surgery to remove the mucus munchers, which recovered 10 larvae at various stages and a pupa. A genetic test and DNA sequencing confirmed they were sheep bot flies, as did visual inspection of two third-stage larvae and the puparium.
Not only had experts never found a pupa in a human snout before, but they also thought the advancement to that stage was “biologically implausible.”
“The paranasal sinus environment does not meet temperature and humidity requirements for pupation, and host secretions, immune responses, and resident microbiota create a hostile milieu for pupal advancement,” the experts, led by Ilias Kioulos, a medical entomologist at the Agricultural University of Athens, wrote.
Still, in this poor woman’s nose, the pests persisted. Kioulos and his colleagues speculate that two factors favored the fly’s festering infection in the woman: a large initial dose of larvae and her severely deviated septum.
“From a purely anatomic perspective, we hypothesize that the combination of high larval numbers and septum deviation impeded normal egress from the nasal passages, permitting progression to the [third larval stage] and, in 1 instance, pupation,” they wrote. In other words, there were so many maggots in her crooked nasal passage that they created a bottleneck on their way out, allowing some to stay longer than usual. The other, equally disturbing possibility, is that the flies are adapting to using human noses for their full life cycle.
The experts note that, in a way, the woman was lucky. In animals, the third-stage larvae can’t pupate when they become trapped in the sinuses. Instead, they either dry out, liquify, or calcify, which can all lead to secondary bacterial infections.
From here, Kioulos and his colleagues warn that clinicians should be aware of the potential for human cases of sheep bot fly infections, which are widely distributed around the globe.
