Sudden erythema (three-day fever, three-day fever) is an infectious disease affecting primarily children aged 6 months to 2 years. Its most characteristic symptom is a sudden, very high fever. Check what to do if the child develops a sudden erythema.
Sudden erythema( three-day fever ,three-day fever , sixth disease, Latin exanthema subitum ) is a viral disease caused by HHV-6 and HHV-7 viruses. Experts estimate that the 3-day week is the most common infection in infants, and as many as half of all childhood fever is caused by it.
The disease takes 5 to 15 days to hatch and is highly contagious. Unfortunately, it cannot be prevented, but fortunately it is a minor disease and actually never causes complications.
Sudden erythema: symptoms
The first symptom of sudden erythema is the unexpected appearance of a very high fever - reaching even 40 degrees C; which lasts for 2-4 days.
It is not accompanied by other symptoms, such as cough or runny nose, nor does the urine test show, for example, an infection of the urinary system.
Occasionally, you may notice enlarged peripheral lymph nodes and you may have diarrhea. The fever usually lasts for three days, hence the sudden erythema is called a three-day or three-day fever. When the high temperature has subsided by itself, a rash appears on the skin - a small, pale pink rash that disappears fairly quickly.
Sudden erythema: rash
The rash accompanying sudden erythema is similar to that of rubella - tiny red spots or papules on the body and neck, slightly less on the face and occasionally on the limbs.
Characteristic of the rash that accompanies a three-day party is that it disappears after pressure.
The rash is not exudative, so it does not need to be lubricated, and there are no bacterial superinfections. After a few or several hours, the rash fades and disappears completely.
Sudden erythema: treatment
In the treatment of erythema, only drugs are used to reduce high fever to prevent seizures.
You should also remember to give your child enough fluids to prevent dehydration.
If antipyretic drugs are working, and there are no othersIf you have any disturbing symptoms, you can wait to see your doctor, but if your child does not respond to fever-lowering medications, or if you notice any other disturbing symptoms, contact your pediatrician as soon as possible.
To confirm the diagnosis, you can perform a blood smear, ESR and CRP (preferably on the third day after the onset of symptoms).
Testing for specific antibodies is rare.
