People can do several things to prevent Giardia. Some of these include:
- Practicing good hygiene
- Avoiding food and water that might be contaminated
- Avoiding fecal exposure during sexual activity.
Giardia lamblia was initially named Cercomonas intestinalis by Lambl in 1859, and was renamed Giardia lamblia by Stiles in 1915, in honor of Professor A. Giard of Paris and Dr. F. Lambl of Prague; however, many people consider Giardia intestinalis to be the correct name for this parasite.
