Adults are given roundworm shots at most once a year. Ascariasis is one of the more common parasitic diseases in human body. The eggs of roundworms hatch in the duodenum, and the output larvae burrow into the wall of the small intestine, then migrate to the heart and lungs through blood circulation, and are swallowed back to the small intestine by the lungs along the bronchus up to the oropharynx, and develop into adult worms in the small intestine. Patients mainly show symptoms such as pain around the umbilicus and loss of appetite, and in serious cases, intestinal obstruction, intussusception and even intestinal perforation can occur. At present, people’s living standard has improved and the living environment hygiene has obviously improved, so the chance of adult infected with roundworm is obviously reduced, so you can choose the number of roundworm shots according to your personal situation. If the surrounding environmental sanitation is good, there is no need to beat roundworms frequently; if the surrounding environmental sanitation is poor, you can beat roundworms once a year; if you have abdominal cramps, decreased appetite and are diagnosed by a doctor as intestinal roundworms, you should take medicine for beating roundworms, such as albendazole tablets, in time. Since roundworm disease is mainly due to unclean diet, poor surrounding sanitation and eating raw and cold food, resulting in roundworm eggs entering the human body, patients must pay attention to dietary hygiene on a daily basis.
