What is baby roseola and what are its features

If you find that a child has developed roseola for children, you should not panic, since this disease often occurs in a mild form. But you need to understand that in order to avoid errors in the diagnosis, it is necessary to show the baby to the doctor. Today we will reveal all aspects of baby roseola and talk about the cause of this disease, consider what doctors recommend when a child is faced with this problem and understand how baby roseola is treated and prevented.


Sudden exanthema, namely baby roseola, is an infectious disease of herpetic origin. This disease has not been fully studied by scientific medicine. To make an accurate diagnosis, differential diagnosis is necessary. Related to this is that similar symptoms can be encountered with completely different childhood diseases, such as acute respiratory disease or allergies. The symptoms of roseola baby are very similar to those of rubella, which is why this disease is called pseudorubella .

Roseola childhood is one of the most common viral diseases that affects children under the age of 3 years. Typically, roseola infantum occurs in children between the ages of six months and 2 years. Pseudo-rubella children get sick once in a lifetime. At the age of 4 to 5 years, antibodies are determined in children. Seasonality – spring, early summer and autumn. To a greater extent, sudden exanthema resolves without complications over a period of 4 to 6 days.

The main causative agent of childhood roseola is the sixth type of herpes, less often – the herpes virus of the seventh type. From 5 to 15 days – the incubation period. Between 6 and 24 months of age is the time of maximum manifestation. Roseola is a disease exclusively for children. It occurs in both girls and boys in exactly the same way.


Despite the fact that childhood roseola is a widespread disease, newborn babies have maternal antibodies that protect them. But by 4-6 months of life, the amount of antibodies in the baby is rapidly decreasing and the child involuntarily becomes susceptible to a viral disease.

Most often, the virus can be transmitted by airborne infection of healthy children from a sick child.

Children can become infected through direct contact with the virus carrier when kissing through salivation.

Sudden exanthema in children can occur in a domestic way through contaminated household items or toys.

In the future, after the disease, a sufficiently strong, stable type-specific immunity is intensively developed. At the age of 5 years, children are not prone to infection. By this age, children are already forming antibodies to the roseola virus. It does not matter in what form the disease took place – be it a vivid clinical picture or an asymptomatic course of the disease.


When infected with roseola infantum virus in children, the symptoms are expressed as follows:

A sharp increase in body temperature, sometimes it reaches 41 degrees. Most often, children have manifestations of fever – retention of body temperature can last for hours (short) or several weeks (long). Fever can be subfebrile (up to 38 degrees), moderate (febrile – up to 39 degrees), pyretic (high – up to 41 degrees) and hyperpyretic (excessive – over 41 degrees). Often, this painful condition of children, both parents and pediatricians, is considered as SARS or teething.

A skin rash of varying intensity is formed. As a rule, these are pink pale spots in diameter from 4 to 6 mm. Around some spots there is a border of a white halo. The rash spreads rapidly throughout the body of the child. Starting on the baby’s back, it actively arises in the area of \u200b\u200bthe baby’s breast, on the tummy. Appears in the folds of the arms. Areas of the face and legs are practically not affected by pseudorubella , in rare cases there are minor rashes. Based on such symptomatic signs, the disease was called roseola or sudden exanthema.

Rashes of sudden exanthema disappear almost without a trace on the second or third day. In rare cases, leave some skin changes in the form of peeling. Soon these areas of damage are restored.

Roseola childhood disease can occur either with small, non-serious rashes, or completely without them. Parents do not always know that the child has had a sudden exanthema if roseola manifested itself as symptoms in the form of a rash during the night, and by morning the rash disappeared without a trace.


Below you can see a photo of sudden exanthema in children. If you look closely, it becomes clear why this disease is called pseudorubella by many . Therefore, when a child has symptoms of rashes similar to those in the photo, it is necessary to make a differential diagnosis from rubella and other similar diseases, which are listed in the diagnosis section.


When contacting a pediatrician, the doctor conducts an external examination of the child. Gives a referral for a blood test. Serological diagnosis is rarely performed. It is extremely important not to confuse baby roseola with an allergic rash when making a diagnosis. It is also necessary to distinguish pseudorubella from sepsis and bacterial pneumonia, as well as to differentiate from measles, enterovirus non-polio infections, rubella, infectious erythema, otitis, meningitis.


Before taking any independent action, it must be remembered that self-treatment is highly discouraged. It is imperative that you contact your local doctor. After the examination, the doctor gives certain settings:

children with high body temperature should not be in contact with other babies and it is necessary to isolate them until complete recovery;

if there is no fever and fever does not cause problems and inconvenience to the child, then there is no need for medical treatment;

you can lower the fever by lightly bathing the child in warm water, if the baby starts to freeze, it is necessary to slightly increase the temperature of the water;

do not use alcohol-containing solutions for rubbing the body;

in rare cases, anticonvulsant drugs are prescribed to lower the temperature and for prevention;

in order to eliminate or prevent seizures, it is necessary to turn the baby on its side, loosen the clothes around the neck, put a pillow under the head, and nothing should be in the mouth.

Sudden exanthema has no specific treatment. To significantly alleviate the morbid condition of children at high temperatures, antipyretic drugs such as nurofen or paracetamol are given. For the symptomatic treatment of pseudorubella , a child with immunosuppression is additionally prescribed drugs such as Acyclovir or Foscarnet .

Summing up, it is worth recalling that children’s roseola should be correctly diagnosed. In addition, we must remember that treatment for this disease is not always necessary, and for the purpose of prevention, it is necessary to more often monitor the baby and the children with whom he communicates.
