Worms are very common in the USA and are endemic in the the southern states. As a child I had a stool test every year. I often took pills for hookworms. As an adult no doctor has ever prescribed a stool test, even when asked about the likelihood of parasites. One doctor mumbled something to the effect that "if you have worms it will show up in the blood tests..." but I think he was full of it, as usual: https://www.cdc.gov/parasites/references_resources/diagnosis.html https://www.cdc.gov/parasites/references_resources/diagnosis... I often walk or run barefoot; I don't usually use insect repellant. I eat wild berries and leaves sometimes. Bugs bite me and sting me. I am likely periodically exposed to parasites. An annual test for parasites seems like a good idea. But, since my doctors (most whom are from Asia and should know better) do not concur, I also treat myself to anti-parasitic medications occasionally.
