Infectious erythema - a disease caused by a virus human type B19. To date, the disease
It has not been studied sufficiently, although the underlying causes and methods of infection have been identified.
Especially the spread of infectious erythema in children, although adults can also get sick. The disease is related to respiratory infections, as transmitted by airborne droplets.
Infectious erythema in children with weakened immune systems may be indicative of diseases of the blood or the presence of any chronic disease.
Symptoms of infectious erythema
Symptoms of the disease can vary depending on several factors: age, there are problems with the system of blood and other comorbidities. The very first symptoms of infection are respiratory symptoms that resemble the early period of a cold or flu. The body temperature rises, there is a runny nose, itchy nose, sneezing, scratchy or sore throat, headache, chills, loss of appetite, general weakness of the body.
After several days at body rash occurs. Some patients have a rash accompanied by severe weakness in the muscles and joints. As clinical signs of infectious erythema similar to different diseases, so doctors often find it difficult to put the correct diagnosis.
Often the disease is confused with other viral and microbial infections: roseola, German measles, scarlet fever, measles. Sometimes infectious erythema can be confused with a variety of allergic reactions to certain medications or contact dermatitis. With such symptoms occur, some connective tissue disorders: systemic lupus erythematosus, rheumatoid arthritis, scleroderma.
Among the main manifestations of infectious erythema include symptoms similar to colds. They appear after a couple of days after exposure to the virus in the body. For the patient, they often remain almost unnoticed. When subclinical disease rash may be short-term and then the patient does not realize that the sick. Typical for the same is accompanied by pain in the abdomen and head, pain in the joints, fever up to 38 degrees, general malaise.
The rash usually appears on the body on the fifth day after zarazheniyanetipichnom current can be infectious erythema without rash.
The manifestation of the rash is a certain character and takes place in several stages. Initially, there are bright red rash on the cheeks. The person at the same time looks like a child whipped cheeks. Sometimes the rash spreads to the forehead and chin. This rash lasts for several days and then disappears.
The second phase precipitation occurs in the trunk, neck, shoulders and upper arms, buttocks, knees and upper shins. Externally, the rash looks like a red circular spots, which later grew into a "lace". Eruptions are accompanied by itching and hold on the body for about a week, then disappear completely. However, under the influence of sun or stress may reappear in the same places and not go up to three weeks. Re-emergence of the rash is not necessarily talking about deterioration.
Complications of infectious erythema
Infectious erythema in children can cause a variety of complications, but not always. First of all, the period of the disease may stop the synthesis of red blood cells (red blood cells). Typically, this complication in healthy people goes unnoticed and causes no significant problems with hematopoiesis.
If the patient already has problems with the system and red blood cells in particular (sickle-cell anemia, thalassemia), then it can cause serious complications in the blood system. Suspension of red blood cell production may occur in aplastic Stroke for up to 7-10 days.
more infectious erythema is for people with aplastic anemia. In these patients, the disease is accompanied by apathy, bouts of fever, heart palpitations and other unpleasant symptoms.
Infectious erythema in children with immune deficiency may develop into a chronic form, which ultimately lead to the development of serious damage to blood formation and bone marrow with the formation of resistant anemia.
Diagnosis of infectious erythema
As already mentioned earlier, laboratory and clinical diagnosis of this disease presents certain difficulties. As a rule, infectious erythema can be assumed by the presence of typical rash "lace."
For the diagnosis of infectious erythema necessary to carry out laboratory tests: serological examination for the detection of antibodies to a number of common blood tests to determine the level of red blood cells. Also important is the number of platelets and white blood cells, as they are also involved in the process of hematopoiesis and reduced along with red blood cells.
General blood test also provides an opportunity to evaluate the effectiveness of therapy and the beginning of recovery.
Methods of treatment of infectious erythema
When an infectious erythema in children and adults show home treatment. The principle of treatment is the same as that of all viral infections. During fever need to comply with bed rest and take plenty of fluids and symptomatic and antiviral drugs.
Importantly, the presence of the second and third wave of the rash does not indicate the severity of the disease, and it is a characteristic feature. At the time the disease is to limit the hot tubs, as well as exposure to the sun and in a sun deck, as it provokes repeated eruptions.
In the treatment of infectious erythema antibiotics are not prescribed as this viral disease. However, antibiotics may, if a disease associated angina, otitis media, pneumonia or microbial complications.
A certain danger is the disease during pregnancy, as well as for people with blood disorders or weakened immune systems. In this case, the treatment of infectious erythema can be performed in a hospital under constant supervision of laboratory parameters and hematopoiesis. Pregnant women appoint more ultrasound fetal status, as well as detailed analyzes on the blood and coagulation.
No quarantine measures in the treatment of infectious erythema do not accept, as a patient with the onset of the rash becomes quite contagious, so the well-being may lead normal life.
At present, scientists are actively developing a vaccine against the virus B19, so it is possible that in the near future will be vaccinated against the disease.
