Do babies need to be vaccinated against rotavirus to prevent diarrhea? A parent asked the doctor: It’s winter, and the baby doesn’t usually have “diarrhea”. Is it necessary to get a rotavirus vaccine?
Winter and spring are the high incidence of rotavirus diarrhea. Now you can still get the vaccine if you don’t have diarrhea. It will be late after the diarrhea.” It seems that the parents of children don’t know much about the disease caused by rotavirus. Let me give you popular science.

01 What is rotavirus
Rotavirus is an important pathogen of diarrhea in humans, mammals and birds. It is shaped like a wheel, so it is named “Rotavirus.” There are 10 groups of rotavirus in total, numbered A-J in English letters. Among them, group A is the most common one, and more than 90% of cases of human rotavirus infection are also caused by this group.

The incubation period of rotavirus diarrhea is 1 to 4 days, usually less than 48 hours.

Stool is watery, milky white or light yellow, no pus or blood, rapid defecation, large volume, no fishy smell, infants may complain of abdominal pain. Gastrointestinal symptoms usually end in 3 to 7 days. The course of the disease is generally 5 to 8 days (1-10 days), with an average of 2.9 days, and can last up to 30 days in individual cases.

Central nervous system infection can manifest as convulsions, viral encephalitis or meningitis, Reye syndrome, epilepsy, polio-like syndrome, etc.; respiratory infections may cause Acute pharyngitis, bronchitis and pneumonia; it can also cause hepatitis and kidney damage; when combined with myocarditis, sudden death can occur in severe cases; diffuse intravascular coagulation, acute pancreatitis, etc.
