Is rotavirus positive serious?

Many parents have encountered the situation of baby diarrhea. If the baby continues to have diarrhea, parents should take the baby to do a routine urine test. Usually the test result is positive for rotavirus, which is the cause of the baby's diarrhea. The main reason is that the baby is still young and his body resistance and immunity are relatively weak. It is often difficult to overcome viral infection, so it is necessary to improve the baby's immunity and improve physical condition. Is rotavirus infection serious?

Rotavirus is one of the main pathogens that cause diarrhea in infants and young children. It mainly infects small intestinal epithelial cells, causing cell damage and causing diarrhea. Rotavirus is prevalent in summer, autumn and winter every year. The infection route is fecal and oral. The clinical manifestations are acute gastroenteritis and osmotic diarrhea. The course of the disease is generally 7 days, with fever lasting for 3 days, vomiting for 2 to 3 days, diarrhea for 5 days, and severe dehydration symptoms.

Rotavirus is a double-stranded RNA virus belonging to the Reoviridae family. It is the single leading cause of diarrhea in infants and young children, and nearly every child in the world by the age of about five years has been infected with rotavirus at least once. However, after each infection, the body's immunity will gradually increase, and the impact of subsequent infections will be reduced, so adults are rarely affected. There are eight types of rotavirus, numbered alphabetically as A, B, C, D, E, F, G and H. Among them, type A is the most common one, and more than 90% of human rotavirus infections are caused by this type.

Rotavirus is transmitted via the fecal-oral route. It infects the intestinal mucosal cells connected to the small intestine and produces enterotoxins, which cause gastroenteritis, severe diarrhea, and sometimes even death due to dehydration. Although rotavirus has been recognized for a long time and causes more than 50% of severe diarrheal hospitalizations in infants and young children, it is still not widely recognized in the public health community, especially in developing countries. In addition to its impact on human health, rotavirus can also infect animals and is a pathogen of livestock.
