Symptoms of Infection in Humans
Symptoms usually began to appear 6–11 days after initial infection, beginning with a fever and cough. Most cases reported a progression to a persistent cough, leading to expectoration and sometimes hemoptysis. Worms in the bronchial region can trigger a chronic, nonproductive cough and asthma-like symptoms due to the obstruction of airways by the worms. These symptoms along with a low-grade fever can last for several months if not initially diagnosed correctly. A scratching or crawling sensation can be felt in the throat if the worms are attached in the larynx. Weight loss and pneumonitis have been reported as possible long-term consequences, but not anemia.
Recently, M. laryngeus worms were found in the duodenum of a Thai patient, which was the first gastrointestinal case of Mammomonogamiasis. The patient complained of chest pain, haematemesia, melaena, abdominal bloating, but no respiratory symptoms. Although nothing conclusive was determined, it is possible that the adult worms were dislodged from the larynx, re-swallowed, and later found in the duodenum.

“There is one great fact, characteristic of this our nineteenth century, a fact which no party dares deny. On the one hand, there have started into life industrial and scientific forces which no epoch of former human history had ever suspected. On the other hand, there exist symptoms of decay, far surpassing the horrors recorded of the latter times of the Roman empire. In our days everything seems pregnant with its contrary.”
—Karl Marx (1818–1883)
“In retirement, only money and symptoms are consequential.”
—Mason Cooley (b. 1927)

But an infection of the common sky
That sagged ominously upon the earth”
—Robert Graves (1895–1985)
