Infectious and parasitic diseases

How is hepatitis B transmitted?

Transmission of the hepatitis B virus is carried out exclusively parenterally: by transfusion of infected blood or its preparations (plasma, erythrocyte mass, albumin, protein, cryoprecipitate, antithrombin, etc.), use of poorly sterilized syringes, needles, cutting tools, surgical procedures, dental treatment, endoscopy study

Hepatitis E treatment

Treatment of hepatitis E is the appointment of a set of therapeutic measures, as with other viral hepatitis. Hospitalization is compulsory. Bed rest is maintained until the symptoms of intoxication disappear and a clear tendency to normalize the indicators of functional liver samples.

Hepatitis E symptoms

Symptoms of hepatitis E begin gradually with the appearance of asthenodyspeptic signs. Weakness is observed, increasing during 3-4 days, worsening of appetite, nausea, abdominal pain.

Inguinal lymphadenitis

Inguinal lymphadenitis is a disease characterized by inflammation of the lymph nodes in the groin area. There are a lot of reasons for its appearance, but infectious diseases (especially those that are sexually transmitted) remain the dominant among them.

How is hepatitis A spread?

The causative agent of hepatitis A is transmitted exclusively by the fecal-oral route, through infected foods, water and through household contact. The virus is excreted only with feces, and it gets into food usually when the elementary rules of hygiene are violated at the time of its processing and preparation; water contamination occurs by contamination of water sources by household discharges.

Prevention of hepatitis A

Prevention of hepatitis A is the same as with other intestinal infections. It is built taking into account the three links of the epidemic chain (the source of the infection, the route of its transmission and the receptive organism).

Hepatitis C Virus Genotypes

There are 6 genotypes and 11 major subtypes of the hepatitis C virus. Genotype 1, especially 1b, causes a more severe course of the disease and is most resistant to treatment. In this case, a higher level of viremia is usually recorded. On the basis of genetic heterogeneity of HCV strains, it was suggested that the divergence of genotypes of the hepatitis C virus occurred approximately 300 years ago.

Why do the lymph nodes in the neck ache and what to do?

If the lymph nodes in the neck hurt, then we may well suspect that the site of infection is located near the site of lymph nodes.

Chronic lymphadenitis

Chronic lymphadenitis is characterized by infectious inflammation for a long time, localized in the lymph nodes. The immune system of a person and lymph nodes, as an integral part of it, by its functions prevent penetration into the body and eliminate all kinds of infections and inflammations.

Inflammation of the lymph nodes

In medicine, an inflammation of the lymph nodes is called lymphadenitis. The disease develops when the infection enters the human lymphatic system. Throughout the length of the lymphatic vessels are lymph nodes, which have different sizes.
