1. What is fifth disease?
Fifth disease is a viral exanthematous infection caused by Parvovirus B19.
2. Why is it called 'fifth' disease?
Because the various exanthematous diseases have been classified with a numerical order and infectious erythema was given fifth place, after measles, scarlet fever, rubella and what was once identified with atypical scarlet fever or 'scarlet fever' (see also fourth disease or scarlet fever).
3. At what age does it contract?
Mainly from 4-5 years up to adolescence and the period of the year in which it occurs most often is from mid-winter to mid-spring. It is a very common disease: about half of the population already has antibodies, so they are protected.
4. Symptoms: how is fifth disease recognized?
- cheeks flushed and hot
- after a few days, the rash also passes on the arms, legs and trunk
- in some children there are also flu-like symptoms
The most typical symptom is represented by the so-called slapped face: the cheeks are red and warm, as if the child had been slapped. After a few days the rash spreads on the arms, legs and, to a lesser extent, on the trunk, with patches of about 1 cm in diameter, red-pink in color, usually isolated and undetected, which may have a ring-like appearance , clear in the center and reddened at the edge. Sometimes they are itchy. In some children, flu-like symptoms such as low-grade fever, mild general malaise, muscle aches, runny nose, headache may occur 7-10 days before the onset of the 'slap face'.

7. When are you contagious?
The fifth disease is contagious only in the days immediately preceding the appearance of the rash, therefore even before it is clearly understood that it is a fifth disease.
8. The course of the disease?
The fifth disease is a disease annoying but benign, which just requires a little patience. In most cases, all symptoms go away within ten days, but sometimes the rash can persist for 2-3 weeks, especially if the skin is exposed to sun, intense cold or heat, or physical exertion.

The general rules of hygiene are useful, that is, wash your hands often, do not put your hands in your mouth, use disposable handkerchiefs.
