Helminths in medicine are called worms that lead a parasitic lifestyle in the body of their owner - a person. Both adults and children are susceptible to infection with worms. There are many types of these parasites. The symptomatic picture of infection with worms is always variable in nature, it all depends on what type of parasites the person was infected with. If the infection occurred immediately with a large number of worm eggs, then a significant deterioration in health may occur on the second day.
