Buttons in children: recognize chickenpox and rubella

What is the common point between chickenpox and rubella? Both are eruptive diseases that affect mainly children. Characterized by the appearance of small pimples, these two childhood diseases are not always easy to differentiate for neophytes. Yet some clues can help you identify them.

Buttons, plaques, papules ... what differences?

Doctors rarely use the term "buttons"to designate one or more cutaneous lesions In the medical language, one speaks more about papules, vesicles, phlyctenes or even macules to qualify precisely this type of clinical manifestations." Thus, the phlyctene is the medical name serving to designate a blisters while the papule, it is a small dermatosis smooth and firm, without flow.In contrary to popular belief, most eruptive diseases of the child do not result in the occurrence of pimples but plates. varicella is characterized by larger skin growths that can be described as pimples.

The pimples of chickenpox

Caused by a virus belonging to the family of herpeschickenpox is the best-known eruptive disease. Particularly contagious, this infectious pathology manifests itself symptomatically by the appearance of small pinkish papules not exceeding 2 to 3 mm. As the viral spread progresses, the cutaneous involvement changes and the lesions are gradually filled with a transparent liquid to form what are called vesicles. These are usually accompanied by moderate fever and severe itching. They occur in the form of relapses for a period of between 24 and 48 hours. The rash is likely to affect the whole body, from the scalp to the feet. The most affected children can even develop pimples in the oral cavity. A few days after the acute phase, the vesicles eventually dry and then crusts.

The buttons of rubella

Often less expressive than her sister chickenpox, rubella is also part of contagious eruptive diseases. At first, the infantile pathology is manifested by a feverish state which is associated with muscular pains, headache, a cough, or even conjunctivitis. On palpation, we often notice the swelling of several lymph nodes, especially those located in the neck. The diagnosis is more easily established a few days later when the first macules appear on the surface of the skin. These small pink spots begin by invading the face before descending into the neck, trunk and then towards the limbs. The rash does not persist for more than two or three days.

Chickenpox, rubella ... what treatments?

Like all viral diseases, these two childhood diseases do not require antibiotics. Only the symptoms are subject to medical care. Thus, fever is mainly controlled with the administration of antipyretic drugs adapted to the age of the child while the skin lesions should be disinfected daily. In case of severe itching, antihistamines are sometimes advocated to reduce inflammation. Some serious forms of chicken pox can be treated with antivirals. This is particularly the case with the newborn or the pregnant woman. Of course, the child will have to stay at home until complete healing to avoid the risk of contamination.

What prevention?

Only rubella is one of the compulsory vaccines for children. This is the famous MMR for "Measles-Mumps-Rubella". The first injection is scheduled for 12 months while the booster is scheduled between 16 and 18 months. For its part, vaccination against chickenpox is not the subject of a recommendation in children. However, it is recommended from 12 years for people who have not contracted the disease during their childhood.
