Ascariasis is a common helminthic infection, with an estimated worldwide prevalence of 0.8-1.22 billion people. But it’s rare in the USA because it’s not endemic. Most often seen in travelers I’m inclined to think I missed cases during my years of practice.

Update your knowledge and listen to the EMRAP November podcast or hit the high points in the PDF file. Annals of Emergency Medicine: Ascariasis by Jessica Mason MD, Andy Grock MD and Andrea Tenner MD 

I’d like to hear from our Nepal colleagues’ pearls on recognition and the complications. Leave a comment. How often have you seen asymptomatic versus symptomatic cases? What’s the worst complication you’ve managed?

Who knew? “During our relatively short history on Earth, humans have acquired an amazing number of parasites, about 300 species of helminth worms and over 70 species of protozoa. Many of these are rare and accidental parasites, but we still harbor about 90 relatively common species.” Clin Microbiol Rev. 2002 Oct; 15(4): 595–612.
