China News Service, May 29 (Reporter Chen Jing) Diarrhea is the second leading cause of death among children under 5 years of age.

But this disease can be prevented and treated.

  In an interview on the 29th, Zeng Mei, deputy director of the Department of Infection and Infection, Director of the Department of Infectious Diseases, Director of the Department of Infectious Diseases, and Director of the Vaccination Clinic of the Children's Hospital of Fudan University, asked the public to understand the "triple crime" of rotavirus: it is dangerous, hard to prevent, no special medicine, and don't ignore it.

Parents should get the rotavirus vaccine as early as possible from the 6th week of the baby.

  It is reported that rotavirus is the leading cause of severe dehydrating diarrhea in children under 5 years of age worldwide.

Zeng Mei told reporters that most of the other confirmed cases of infectious diarrhea in China are viral diarrhea.

Rotavirus is one of the most important causes of severe dehydrating diarrhea in children under 5 years old. Almost every child has been infected with rotavirus before 3-5 years of age.

  According to reports, rotavirus is a non-enveloped double-stranded RNA virus. Because of its unique appearance, the virus particle looks like a wheel when observed under an electron microscope, so it was named rotavirus.

Zeng Mei said that rotavirus mainly invades small intestinal villi epithelial cells, causing cell damage and reduced villi absorption capacity, which leads to diarrhea.

  Zeng Mei told reporters that the clinical manifestations of rotavirus infection vary from severity to severity, and may be asymptomatic, or may have symptoms of "one" vomiting, "two" diarrhoea, "three" fever and vomiting, and may cause serious complications and may even be life-threatening.

The expert told reporters that 80% to 90% of sick babies will have vomiting, and diarrhea can last up to 9 days, with an average of 10-20 times a day; more than one-third of babies may have a fever of more than 39°C.

  Rotavirus is hard to guard against.

Zeng Mei told reporters that in China, rotavirus infection may occur throughout the year.

It is difficult to prevent the virus by ordinary means. Rotavirus can survive on the hands for several hours and on the surface of the toy for several days, and ordinary soap or disinfectant cannot effectively prevent rotavirus.

There are many subtypes of rotavirus, and even if the infection is cured, it is still possible to infect again.

At the same time, there is currently no specific cure for rotavirus diarrhea.

  It is reported that rotavirus can enter the bloodstream and cause systemic infections, spleen injury, myocardial injury and myocarditis, pneumonia and bronchitis, acute hemorrhagic cerebral edema in infants, systemic inflammation, skin vasculitis and other autoimmune diseases.

Zeng Mei said that severe cases may cause convulsions, viral encephalitis or meningitis, epilepsy, etc., severe dehydration, electrolyte imbalance, acidosis and life-threatening.

  It is reported that 6 months to 2 years old is the age group with the highest incidence and the most serious.

An epidemiological study in China showed that among children with rotavirus diarrhea, more than 60% occurred before 1 year old, and more than 90% occurred before 2 years old.

The younger the baby is infected with rotavirus, the more serious the condition may be.

  Zeng Mei advocated vaccination against rotavirus, early vaccination and early protection.

Mothers-to-be should prepare immunization plans for their babies as soon as possible, and pay attention to vaccine-related knowledge to prevent rotavirus as soon as possible.

She suggested that when the baby was vaccinated for the second time, he should ask the vaccinator for information about rotavirus vaccine in time to prevent missing the vaccination period.
