Hepatitis A in developing countries with lowthe level of economic and social development is primarily the children's infection. The majority of children in these countries perebolevaet hepatitis A to 10 years of age and acquires lifelong immunity.
As shown by epidemiological studies,the number of registered manifest forms (when there is a typical manifestation of the disease) is significantly lower than those in whom antibodies to hepatitis A. This means that many children carry infection anicteric in form and in this period, hepatitis A is not recognized.
In developed countries, hepatitis A, also called"Disease of dirty hands", sick is difficult because of the high culture of the population and the excellent work of municipal services. Therefore persons who have antibodies to the infection very little of it and the risk of getting in contact with the hepatitis A virus is quite high.
Most often this happens during business trips and tourist trips to tropical countries, with African and Asian resorts in the Central Asian republics.
To determine the probability and the degree of riskinfection, but rather, in order to resolve the issue of the need for vaccination, carried out blood tests for antibodies to hepatitis A virus immunoglobulin class G (anti - HAV IgG). If these antibodies are found in the blood, it means the presence of immunity to the virus, there is a risk of infection is zero and vaccination against hepatitis A is not needed. If no antibodies, the risk is. Welcome to the vaccine!
CDC epidemiologists identify the following risk / vaccination requirements
- Members of the family (household) of an infected person with hepatitis A virus
- Persons having sex with an infected
- Persons, especially children, living in regions with a high prevalence of hepatitis A
- Those bound for countries with a high incidence of hepatitis A
- Men practicing homosexual sex
- People who use drugs (injectable and injectable)
