Infectious erythema refers to viralinfection, which causes parvovirus rights (B19). Infectious erythema is also called the fifth disease, before it go: measles, scarlet fever, rubella, Filatov-Duke disease, infant roseola. Experts believe that the infection is infected by airborne droplets, but the replication of this pathogen is not found in the nasopharynx, which puts this conclusion in doubt. Traces of parvovirus are not found in urine and feces.
Infectious erythema in children is more common,than in adults, especially at the age of 4-10 years, in the winter and spring season. Adults infected with the virus may not even notice this, since infection often occurs without symptoms. But there can be rare situations when infectious erythema in adults occurs with a high fever, sometimes delirium, headache and muscle pain. Often in adults, the rash is not manifested. After the infection, immunity remains - the second time erythema is not affected.
Symptoms of viral infection begin to appeareven before the onset of rash, may include: pharyngitis, diarrhea, runny nose, nausea, fever, fever and general malaise. During this period the child is the most infectious carrier of the virus.
The next signal is skin rashes thatlike a "slap" or "butterfly wings." First they form small pink or red foci (the area around the mouth is pale), then rapidly increase in size and merge into one erythematous field of irregular shape. The reverse development of the rash starts from the center, the color changes to grayish, violet. The edges of the rash are the brightest color. After some time after the manifestation, it can spread to the limbs and trunk, while the rashes may be different in duration and severity. Infectious erythema lasts, on average, up to ten days, disappears gradually, leaving barely visible pattern on the skin, the skin on this place does not peel.
With diseases of erythema infectious enoughto conduct treatment at home. The patient needs rest, drinking a lot of fluids and taking medications that reduce the symptoms of the disease. Infectious erythema passes by itself, you can help reduce the temperature and other painful symptoms. Antibiotics usually do not take, because the disease is caused by a virus, not bacteria.
There is another kind of erythema -exudative erythema, which refers to diseases that are infectious-allergic. An infectious disease begins with a low temperature and general malaise, after a while, rashes (in the form of blisters, spots) appear on the skin of the palms, genitals, soles or extensor surfaces of the limbs. Similarly, rashes can occur on the mucous membrane of the mouth, on the lips. There are cases when mucous and skin develops a rash at the same time.
Diagnose infectious erythema notpresents difficulties for the specialist. If the lesion is on the mucous membrane of the mouth, the diagnosis can be difficult, since the symptoms are similar to a number of other diseases.
Exudative erythema can have a recurrent manifestation, exacerbation occurs in the spring and autumn, is observed in 50% of carriers of infection. People at risk are young and middle-aged.
Treatment includes the management of the disease andIts profilaku, aimed at eliminating exacerbations in the future. The use of antibiotics is resorted only in cases of secondary infection in the place where there was already a rash. If there are bubbles on the site of the rash, they are pierced and processed with a solution of green.
