Hepatitis C virus and the external environment
anthroponoses Hepatitis C is a viral disease transmitted through the blood: from medical personnel in case of an unintentional damage of the skin with needles infected patients, with the collective use of drugs (administered by injection), during various cosmetic and medical procedures (such as dental procedures, tattoos, blood, piercings), or via other body fluids.
it is Worth noting that household and contact way of infection is excluded, since in the environment the virus has a very low survival rate. There is very huge risk of transmission of the virus from mother to baby during childbirth directly.
today in the whole world recorded 150,000,000 people patients for hepatitis C.
Every year this strain of hepatitis reveal somewhere 4,0000,0000 people, and the main cause of infection is the spread of drug addiction. Next, we take a closer look at what is the causative agent of the disease.the
What is the main pathogens?
it Should be noted: the main causative agent of the disease is a virus of the genus hepaciviruses and family of flavivirus, which was identified even back in 1898 with the cloning of the genome, which in turn was derived directly from the blood of chimpanzees infected with the disease.
Its causative agent is a virus which contains RNA. His shell is lepidorostrus supercaps. It has spherical shape and contains six unstructured proteins responsible for replication. A set of genes is non-fragmented single-strand RNA.
This virus has a very high variability – there >14 genetic variants that, in turn, have their own characteristic peculiarities of the infection, your % development of carcinomatosis, as well as cirrhosis and is characterized by the transformation of the disease directly in the chronic form.
the impact of the environment on the virus
As to cultivate the virus directly on nutrient media almost not possible, and the stability of the virus outside the body of its bearer remains open.
laboratory tests found out that the hepatitis C virus:
- very quickly destroyed when exposed to UV radiation;
- when boiling ceases inactive for 120 seconds;
- for many years retains its activity in the temperatures.
