Hepatitis B virus or HBV belongs to Taxonomic Group VII of the Virus Kingdom.

hepatitis B is a viral disease, mainly affect affecting the liver which may become chronic. It is transmitted by sexual means or by contact with blood or objects that are contaminated by this virus. This virus can survive outside the body for 7 days and withstand heat. During this period, the virus is still capable of causing infection if it enters the body of an unvaccinated person. This virus provok provokes inflammatory lesions or degradation of liver cells that are destroyed by the immune system. It is not the virus that causes destruction but the immune system.

If the infection becomes chronic it can give birth to cancer (hepatom). There are treatments for this virus such as interferon which inhibits virus DNA and activates antiviral enzymes.



Vaccination against hepatitis B is mandatory in infants over 2 months of age, it is recommended for children and adolescents under 16 years of age who have not yet been vaccinated and obviously for people at high risk of contracting this disease.
