Adults are unlikely to suffer from ascariasis. According to the data of the National Survey on the Status of Ascaris Infection, the average infection rate of the population is 12.72%, which is lower than that of children due to the fact that most of the adults have good hygienic habits, and the infection rate of adults is less than 12%. Ascariasis is a parasitic disease caused by parasitizing the human small intestine or other organs. It is very widespread and has a high incidence in children. Ascariasis is mainly contracted by swallowing the eggs of infective roundworms, by swallowing the eggs of infective roundworms through the mouth or by accidentally eating food contaminated with the eggs, or by inhalation into the pharynx along with dust flying. The clinical manifestations of ascariasis are related to the site of parasitism, the site of invasion, and the degree of infection. If it is limited to the intestinal tract, it is called intestinal ascariasis, and may present with different degrees of gastrointestinal manifestations. Ascaris metabolites have the potential to cause allergic reactions in the host, manifesting as asthma, urticaria, and conjunctivitis. If the patient has relevant clinical symptoms, please go to the regular hospital for timely diagnosis and treatment, and take anthelmintic drugs under the guidance of professional doctors for treatment in a timely manner, such as albendazole tablets. Be careful not to self-medicate to prevent adverse reactions.
