Hepatitis A is a common disease worldwide, children are among those with a high incidence. However, hepatitis A is preventable by vaccination.
1. Hepatitis A
Hepatitis A is a condition where the liver is inflamed by the hepatitis A virus. It is a single-stranded RNA virus, 27nm long, in the family Hepadnavirus, Picornaviridae. Four well-defined genotypes of hepatitis A have been described in humans, however they belong to a single type of serum. The virus is stable at low pH and moderate temperatures, but is inactivated by high temperatures, chlorine. These characteristics are associated with preventive measures.
Hepatitis A is mainly spread through the gastrointestinal tract, hepatitis A virus is often found in the feces of infected people, in addition to being present in other secreties such as saliva, urine. Any action that spreads viral secreties from one person to another can spread hepatitis A. Virus A exists in the intestinal tract, discharged through the patient's feces. The incubation period of hepatitis A is from 15 to 50 days.
Hepatitis A in children is usually an acute disease with symptoms: fever, discomfort, loss of appetite, vomiting, nausea, abdominal pain or discomfort and diarrhea, pale stools, usually gray (clay), dark urine, jaundice and eye whites. But not everyone infected with the hepatitis A virus develops into a disease. Symptoms can occur between 2 and 6 weeks after the virus enters the body
Symptomatic hepatitis occurs in about 30% of infected children under the age of six, some of them with jaundice. Jaundice usually lasts less than two weeks. Bilirubin and aminotransferase consed return to normal within two to three months.
Acute liver failure is usually very rare, only 1%. However, deaths from hepatitis A infection vary with age. In 2001, the mortality rate in children under the age of 14 was 0.3%; this rate is 0.1% in adolescents and young adults (15 to 39 years); mortality accounts for 0.4% among older adults (40 to 59 years old) and in older adults, the rate is 1.7%.
3. Treatment and prevention
For hepatitis A treatment only helps to support the body and resolve the symptoms. There are no specific methods for treating hepatitis A. The patient's body will eliminate the hepatitis A virus on its own after a few weeks without treatment. Patients can be cared for at home without hospitalization
While suffering from hepatitis A, patients should:
- Eat foods rich in nutrients
- Avoid intimate contact with others
- Regularly see a doctor to monitor the progress of the disease.
- Wash your hands often with soap, especially after going to the toilet, before eating and processing food. Always wash your hands thoroughly with soap and water for at least 20 seconds.
- Ensure personal hygiene, environmental sanitation, water sources.
- Good treatment of feces and waste of patients.
- Cook food, do not eat animals raw or cook uncooked. Hepatitis A virus is destroyed at high temperatures.
- Do not share personal belongings (food items, face towels, towels, toothbrushes, buckets, pots…) with people with diseases.
Disinfection with chlorine and some disinfectant solution (household bleach diluted 1: 100) is enough to inactivate the virus.
Vaccination : Currently,there is no specific treatment for hepatitis A, so vaccination is the best way to prevent hepatitis A. Hepatitis A vaccination can help your child not get sick. The vaccine is about 95% effective in healthy adults and can work for more than 20 years. It is about 85% effective in children and can last 15 to 20 years. This can only be effective when a child is vaccinated immediately after exposure to the virus.
If the child is in contact with a person with hepatitis A, he should be given immunoglobulin within 2 weeks. Vaccinations are also recommended for the target group:
- Traveling or working in a country with a high incidence of hepatitis A like other countries in Africa, in Central and South America. people living in communities with HAV outbreaks.
- Live in an area with high levels of hepatitis A
- Hepatic disease.
- Diseases associated with heath hem bleeding disorders
