Roundworms and Hookworms can both be transmitted to humans. Usually this is due to poor hygiene. Not washing your hands, not wearing shoes, and not cooking properly. I would recommend your friend to contact her physician but I do not think it is anything to be to concerned with. Or many a Veterinarian and staff would be giving it to there offspring. Roundworms and Hookworms can last for years in your soil so please remember to pick up your Dog's stool and dispose of it properly, so as not to contaminate the area where other dog's play and your's from getting the parasites again. Also putting your Puppy on a good Heartworm prevention will deworm him for those parasites monthly. Good luck
