Rotavirus infection is high in summer and autumn, and early vaccination can prevent it to some extent

At the turn of spring and summer, infants and young children pull and vomit, possibly infected with rotavirus. #Essential Handbook for Common Diseases in Children#

Rotavirus (RV) is one of the main pathogens causing diarrhea in infants and young children, highly contagious, the population is generally susceptible, and the main manifestations of infection are acute gastroenteritis, with diarrhea and fever as the main symptoms can be accompanied by vomiting.

Rotavirus infection is a self-limited disease, there is no specific drug, no need to use antiviral drugs, no need to use antibiotics, the main point of care is not to stop diarrhea but to rehydrate, replenish water and electrolytes to prevent dehydration! The way to prevent dehydration is to maintain a diet as much as possible, using oral rehydration salts if necessary.

Rotavirus is sensitive to chlorine-containing disinfectants and insensitive to alcohol. Prevention focuses on washing hands, not only vaccines!

Severe diarrhea in infants and young children can quickly become dehydrated, electrolyte abnormalities, and can be life-threatening, so rotavirus vaccination prophylaxis under 3 years of age is essential. Among them, the multivalent rotavirus vaccine has a strict vaccination time limit, and if it is missed, only 1 dose of monovalent rotavirus vaccine per year.
