Enteric adenovirus

There are many intestinal diseases. When you suffer from intestinal diseases, you are more likely to experience diarrhea, fever, general weakness and mental depression. Many times when you suffer from intestinal diseases, the disease can be cured without treatment. Only when the condition is serious and the patient is dehydrated or comatose, he should be sent to the hospital for examination and treatment in time, and medication should be used in time according to the condition.

symptom

1. Adenoviral enteritis Most infections caused by viral enteropathogens are asymptomatic.

2. In symptomatic infections, the incubation period is 3 to 10 days, usually 7 days. The main symptom of the children is diarrhea, which occurs several to ten times a day. The stools are watery and rarely contain mucus and blood. Rotavirus gastroenteritis in infants and young children may cause severe watery diarrhea that lasts 5 to 7 days and may lead to isotonic dehydration. Adult patients may also have fever, headache, and myalgia. Adenovirus gastroenteritis is characterized by diarrhea lasting 1-2 weeks. Affected infants and children may have mild vomiting, which typically begins 1-2 days after the onset of diarrhea. About 50% of patients develop low-grade fever. Some children may also have symptoms of upper respiratory tract infection such as rhinitis, pharyngitis, and tracheitis. 3% to 6% have pneumonia symptoms.

Causes

Enteric adenovirus refers to adenovirus types 40 and 41. The morphology of these two viruses is the same as that of ordinary adenovirus, with a diameter of 70 to 80 nm, a core part of 40 to 45 nm, containing double-stranded linear DNA, a capsid at the core, and no lipid envelope. It gets its name because it mainly invades the small intestine and causes gastroenteritis.

The serum electrolyte disorders in children with adenovirus enteritis are mainly low potassium, low sodium, high chloride and low calcium. The above characteristics can be corrected during treatment. Among children with adenoviral enteritis, 19.6% had hypokalemia, 22.8% had hyponatremia, and the highest incidence was hyperchloremia, at 25.0%. The chloride ion content in the stool of children with toxic enteritis is relatively lower than that of sodium ions and potassium ions. Hypocalcemia often occurs in dehydrated children, and the more severe the dehydration, the more severe the hypocalcemia.

Features

The main sites of infection by enteric adenovirus are the jejunum and ileum. Its characteristics are that the villi of the intestinal mucosal epithelial cells become shorter, the cells degenerate, become smaller, and dissolve. It also often leads to small intestinal absorption dysfunction, causing osmotic diarrhea.
