| The presence of ascariasis can date back to 2277 BC, where A. lumbricoides eggs were discovered in the fossilized feces of a human from Peru (Cox, 2002). Ascariasis is an ancient disease with records dating back to 1938 and 1600 BC of A. lumbricoides in a Middle Kingdom Egyptian mummy and from the Ming Dynasty in China between AD 1368 and 1644 (Cox, 2002). | The presence of ascariasis can date back to 2277 BC, where A. lumbricoides eggs were discovered in the fossilized feces of a human from Peru (Cox, 2002).

| The first detailed anatomy of A. lumbricoides was depicted in the late 17th century by an English physician - Edward Tyson (Cox, 2002). Soon after, Francesco Redi wrote a book describing the worm; it was one of the first books of parasitology (Cox, 2002). The study of helminthology reached its peak in the 19th century, partly due to these two publications (Cox, 2002). Scientist began attempting to understand the infections caused by Ascaris and how to treat them (Cox, 2002). | The first detailed anatomy of A. lumbricoides was depicted in the late 17th century by an English physician - Edward Tyson (Cox, 2002).

| In 1878, Italian physician and zoologist, Giovanni Battista Grassi, was the first to demonstrate the infectivity of A. lumbricoides by ingesting the eggs found in the feces of those who died from the disease (Cox, 2002; Silva, 2019). It wasn’t until 1922 when a Japanese pediatrician, Shimesu Koino, infected both a volunteer and himself, that he discovered the life cycle of Ascaris in the human body (Cox, 2002). | In 1878, Italian physician and zoologist, Giovanni Battista Grassi, was the first to demonstrate the infectivity of A. lumbricoides by ingesting the eggs found in the feces of those who died from the disease (Cox, 2002; Silva, 2019).
