Infectious and parasitic diseases

Rubella

Rubella (rubella) is an acute anthroponous infectious disease transmitted by airborne droplets, manifested by moderate intoxication, fever, small-spotted rash, polyadenopathy and a high risk of fetal damage when developing in pregnant women.

Measles - Treatment

If complications develop, measles treatment is carried out according to the principles of treatment of these diseases. If pneumonia or otitis media develops, antibacterial therapy is prescribed in accordance with the results of sputum culture for sensitivity to antibiotics. If encephalitis develops, treatment is aimed at maintaining vital functions and combating edema-swelling of the brain.

Measles - Diagnosis

In conditions of low incidence, measles diagnostics is complex and involves assessment of the epidemic situation in the patient's environment, clinical observation in dynamics and serological examination. Typical measles with Filatov-Belsky-Koplik spots, cough, runny nose, conjunctivitis and rash, which first appears on the head, is easily diagnosed based on the clinical picture.

Measles - Causes and Pathogenesis

The measles pathogen was first isolated by scientists D. Enders and T. Peebles from the body of a sick person in 1954. The measles virus is an enveloped single-stranded virus with a negative RNA genome, of the genus Morbilivirus, family Paramyxoviridae, has a special affinity for mucopolysaccharides and glycoproteins, in particular for cellular receptors containing sialic acid.

Measles

Measles (morbilu) is an acute highly contagious anthroponous viral disease characterized by a cyclical course, manifested by general intoxication, maculopapular rash on the skin, pathognomonic rashes on the oral mucosa, catarrh of the upper respiratory tract and conjunctiva. The route of transmission is airborne.

Infection caused by human herpes virus type 8: causes, symptoms, diagnosis, treatment

Human herpesvirus type 8 (HHV-8), a herpesvirus associated with Kaposi's sarcoma, was identified by molecular cloning using Kaposi's sarcoma tissues.

Infection caused by human herpes virus type 7: causes, symptoms, diagnosis, treatment

Human herpes virus type 7 (HHV-7) is a member of the Roseolovirus genus, Betaherpesvirtis subfamily. Electron microscopic examination revealed typical herpesvirus virions up to 170 nm in diameter. The virion contains an electron-dense cylindrical core, capsid, tegument, and outer membrane and has significant morphological similarity to HHV-6.

Infection caused by human herpes virus type 6: causes, symptoms, diagnosis, treatment

Herpesvirus type 6 is considered the most likely etiologic agent of multiple sclerosis, neonatal convulsive fever, and infectious mononucleosis, Epstein-Barr virus- and cytomegalovirus-negative infections, and HHV-6-associated encephalitis. HHV-6 is a cofactor in AIDS, some forms of cervical carcinoma, and nasopharyngeal carcinoma.

Cytomegalovirus infection - Treatment

Medicines, the effectiveness of which has been proven by controlled studies in the treatment and prevention of cytomegalovirus disease. are antiviral drugs ganciclovir, valganciclovir, foscarnet sodium, cidofovir. Interferon drugs and immunocorrectors are not effective in cytomegalovirus infection.

Cytomegalovirus infection - Diagnosis

A patient's blood test for the presence of specific IgM antibodies and/or IgG antibodies is not sufficient to establish the fact of active CMV replication or to confirm the manifest form of the disease. The presence of anti-CMV IgG in the blood only means the fact of exposure to the virus. The newborn receives IgG antibodies from the mother, and they do not serve as evidence of cytomegalovirus infection. The quantitative content of IgG antibodies in the blood does not correlate with the presence of the disease, or with the active asymptomatic form of infection, or with the risk of intrauterine infection of the child.
