Vaginal Thrush SunSmart Discuss this topic in our 'Health Care Forum' Threadworms - Easy And Effective Treatment For Threadworms Threadworms are the single most common worm infection in New Zealand, yet many people may not know they carry them. Infections are more common in children but adults can be affected as well. They can easily go undetected because the signs are difficult to see.
Threadworms grow in the gut of humans - their entire life is based around living in our bodies.
Contrary to the popular belief, threadworms can not be picked up from animals, explain pharmacists. Animals may be infected by other types of worms but transfer to humans is very rare. Worms like whipworm or hookworm are rare in New Zealand because of our good hygiene standards. Pharmacists say threadworms are about as easy to pass on between people as the common cold. For example, a child simply needs to scratch his or her bottom, which has been irritated by the threadworms, to catch some eggs under their fingernails.
