The roundworm, which has been in hiding for many years in China, has reappeared! A few days ago, a 5-year-old boy went to the toilet and discharged a 20 centimeters long, like a free chopsticks as thick as the beige roundworm, diagnosed by a physician, found that may be due to the boy two years ago with the Vietnamese mother to return to his hometown for a short period of time, because of the relatively backward environment of the hygiene, unknowingly infected with parasites caused by.

Dr. Huang Gao-Bin, director of the Children's Infectious Disease Section of China Medical University Hospital, said that "roundworms" are commonly known as "face worms", and the average life span can be up to two years, and each female worm can excrete 200,000 eggs per day, and in the Republic of China before the 50th year, the restroom is mostly a fecal matter, and the people are accustomed to using feces to water their own vegetable beds, and the children are also more likely to play next to the vegetable gardens, and so the eggs are very likely to be consumed by eating. At that time, the infection rate of children in elementary schools was as high as 80%, which was a very common parasitic disease in schoolchildren. As similar restrooms and living environments in the past are still quite common in Vietnam, it is assumed that the children were infected under these circumstances.

Dr. Huang Gao-Bin said that 50 years ago in the Republic of China, people used to use feces as fertilizer for vegetable gardens, which made the proportion of domestic schoolchildren infected with Ascaris lumbricoides as high as 80%. （

Roundworm is a parasitic disease of the human intestines, and the symptoms vary from person to person, including digestive disorders, heterogeneous protein reactions, nausea, vomiting, diarrhea, and hives. In severely infected cases, symptoms such as malnutrition, mental disturbance, insomnia, teeth grinding and night terrors may also occur. In the case of the little boy, for example, the patient returned to Taiwan from Vietnam this New Year's Eve, there have been intermittent stomach pains, slow weight gain, neither taller nor fatter.

Since the country opened up to foreign brides, most of the foreign matches are from Vietnam, Indonesia, the Philippines, and mainland China, with Vietnam accounting for a quarter of the largest number. However, intermarriage and even the custom of returning to the mother's home, every day of the year, and the ensuing derivative problems have surfaced one by one, for example, the prevalence of parasites in schoolchildren is a case in point. Dr. Huang Gao-Bin suggested that *** may not set up a set of inspection mechanism, for the foreign spouse and children of the provincial relatives back to Taiwan to carry out tracking, to prevent the spread of the re-emergence of parasites so as not to cause disaster.
