It is common for children to get ill, but if ones child is down with fever and red spots all over the body; one can only imagine how alarmed the parents can get!
It is only wise to educate ourselves with the possible illnesses involving fever and rash in toddlers. General care tips involve keeping the child as clean as possible to prevent any further complications due to unhygienic conditions.
Symptoms and signs include high body fever, rash around trunk, neck and face, mood swing and convulsions. Prevention involves vaccination, since this is the only preventive measure known to induce immunity in children with the possibility of having Roseola disease. General care by the parents should mainly focus on soothing the child’s symptoms during the period of disease. Symptoms and signs includes a wide spread rash on the body, flu-like symptoms, cough, red spots over the body (even in the mouth) and high fever. Treatment is not virus specific but will target curbing the symptoms and signs of this disease for instance fever is treated by ibuprofen. Symptoms and signs of chickenpox are the classic symptoms for any infectious disease that is fever, sore throat, headache and appetite loss. Prevention is done so by vaccinating the child at 12-15 months first and then 4-6 years of age. Doctors help should be sought if the child develops a rapidly spreading rash and if the rash develops blisters and also if fever is consistently high. Roseola is primarily caused by a virus called human herpesvirus 6 (HHV-6) and less commonly by human herpesvirus 7 (HHV-7).
The signs and symptoms of HHV-6 (or HHV-7) infection vary depending upon the age of the patient. If you wish to treat the fever, acetaminophen (Tylenol and others) can be used to lower a fever.
Figure 1 – The generalized maculopapular rash of erythema infectiosum develops on the neck, trunk, and extremities (A). Patients are most contagious during the mild prodromal phase, which lasts for 2 to 5 days and consists of low-grade fever, headache, and malaise.
This variable prodrome is followed by brilliant red patches on the cheeks, referred to as the "slapped cheek" sign. Although a benign disorder in most children, erythema infectiosum can cause a significant aplastic crisis in patients with hemoglobinopathies (ie, sickle cell anemia), hemolytic anemia, or immunodeficiency. A 10-year-old boy is brought by his mother for evaluation of persistent “acne” that started when the boy was a baby.
An exanthem is a rash, usually of viral origin, accompanied by systemic symptoms such as fever, headache and malaise.
The causative viruses for chickenpox, measles, rubella, roseola, erythema infectiosum (fifth disease), hand foot and mouth disease and a number of other organisms cause distinctive patterns of rashes and prodromal symptoms.
It becomes more important to make a definitive diagnosis if a pregnant woman or immunocompromised patient are exposed to an infected child, as risks to the foetus or patient may be considerable. Erythema infectiosum is characterised by confluent erythematous, oedematous patches or plaques on the cheeks, with sparing of the nasal bridge and periorbital regions. Most women who are infected with parvovirus B19 infection during pregnancy have a satisfactory outcome.
Initially lesions are unilateral and usually begin near the axillae, lateral trunk and upper inner arm or groin.
Certain groups of people, however, such as neonates (infants within the first four weeks of life), adults, pregnant women and those who are immunocompromised due to illness or treatments such as chemotherapy or high-dose steroids, may experience more serious complications. Infection with varicella in the later stages of pregnancy can cause premature delivery or neonatal chickenpox infection. Pregnant women contacting chickenpox within the first 20 weeks of pregnancy need to be offered immunoglobulin, but this is only affective if given before the rash appears. Painful ulcerative lesions occur anywhere in the oral cavity, but are most commonly found on the hard palate, tongue, and buccal mucosa.


Hands and feet - lesions, characterised by 2-3 mm erythematous macules or papules with a central grey vesicle, usually appears shortly after oral lesions, with the hands more commonly involved than the feet. Symmetrical erythema and oedema of the hands and feet progress to petechial and purpuric macules, papules, and patches that are followed by fine desquamation. In PPGSS, the immune response against parvovirus B19 occurs later, after the onset of the skin eruption. Rashes are common in children; most parents would not even note a rash or red spots till it spreads over a large body surface. Since these diseases are preventable with proper measures it is only sad to make a child go through the discomfort and pain by being ignorant and unaware.
This class of bacteria secretes toxins would culminate in a scarlet colored rash on skin types that are sensitive to it.
Bacteria are carried by air droplet, hence coughing and sneezing around a Scarlet fever increases the risk of contracting infection. Therefore keeping the child isolated is preferable; also dishes used for eating and drinking should be washed properly, to avoid contamination.
Doctor should be called as soon as a spreading rash is seen or if a child has a sore throat consistently. Giving the child liquid or semi liquid diet will also help soothe their uncomfortable condition, since a sore throat tends to cause pain and irritation while having solid diet. Convulsions are although very uncommon in children, but are a very serious complication of this disease.
This vaccine is a combination of immunization against 3 diseases that is measles, mumps and rubella. A healthy diet can help cure the disease quickly, in such regards vitamin A plays a very important role.
But the most distinguishing feature of chickenpox is red spots on skin with oozing pus along with severe rash. Also since this disease is contagious to touch the patient should be separated from others till the disease lasts. Roseola has a sudden onset and short duration, and it most commonly affects young children. Infants and toddlers routinely will develop sudden symptoms with a sudden onset of a high fever that lasts for three to five days, irritability, bulging "soft spot" on the head (fontanel), swollen glands in the front or back of the neck, runny nose, puffy eyelids (due to swelling with fluid), and mild diarrhea. It is not necessary to awaken the child to treat a fever unless instructed to do so by a health-care practitioner.
Rubella has a milder prodrome than measles; this typically consists of low-grade fever and anorexia. Popularly referred to as "fifth disease" (a reference to the old nomenclature that identified pediatric exanthemas by number), erythema infectiosum is caused by parvovirus B19.
Prodromal symptoms may also include arthralgia, arthritis, pharyngitis, conjunctivitis, cough, and diarrhea. The erythema fades within hours to a few days, after which a generalized maculopapular rash on the neck, body, and extremities develops. In addition, once the rash has appeared, the patient is no longer contagious and the earlier symptoms have usually resolved fully. The symptoms of the prodrome are usually treated with acetaminophen or ibuprofen to relieve fever and discomfort. The rash appears on the hands and feet after a prodrome of low-grade fever, malaise, anorexia, and posterior pharyngeal ulcerations. Occasionally children present who recently had a high fever but now feel better—yet who have a new rash. Herpesvirus 6 can cause encephalitis as well.14 No therapies have been proven to prevent these febrile seizures, nor is any specific antiviral therapy available for roseola.
Symptoms can be secondary to a reaction to toxin produced by the organism, damage to the skin by the organism or an immune response. Reported fetal defects include mental handicap, cataracts, deafness, cardiac abnormalities, retardation of intra-uterine growth and inflammatory lesions of brain, liver, lungs and bone marrow.


During the course of the condition lesions often progress bilaterally with an asymmetric predominance. The congenital varicella syndrome can cause a range of problems including shortened limbs, skin scarring, cataracts and growth retardation - the risk of this occurring within the first 20 weeks of pregnancy has been estimated to be less than 1% in the first 12 weeks and around 2% between 13 and 20 weeks of pregnancy. The exanthem begins as 2-8 mm erythematous macules and papules, which progress through a short vesicular stage to form a yellow-grey ulcer with an erythematous halo. Therefore, patients with clinical signs of PPGSS secondary to parvovirus B19 are potentially infectious. However, when you find rash accompanied by fever in toddlers, it suggests other health conditions. Due to non-sensitivity some children of the same family might not have a rash, while others may have more pronounced symptoms. Doctor should be called immediately when a child has seizure attacks or if fever is persistent. This rash may start from the central area of the body and then it spreads to other parts quickly. The incubation period between exposure to the virus and onset of symptoms is nine to 10 days.
The rash is not as intense, but it usually follows the same pattern (first the face and neck, then the rest of the body; not palms or soles).
Herpangina presents with low-grade fever, malaise, anorexia, and shallow vesicles or ulcerations of the posterior pharynx (including the uvula, soft palate, and tonsillar pillar). One in particular, enterovirus 71 infection, has been associated with serious pulmonary and CNS complications.13 The identification of serological markers of hand-foot-and-mouth disease may be needed during an outbreak of enterovirus 71 infection. This presentation is typical of roseola, a syndrome characterized by several days of high, unremitting fever followed by defervescence with the abrupt onset of a diffuse macular or maculopapular rash. Symptomatic therapy with antipyretics (other than aspirin), maintenance of good hydration, and reassurance are helpful. Improving diagnostic testing and reducing overuse of antibiotics for children with pharyngitis: a useful role for the electronic medical record. Many exanthems are associated with common winter and summer viruses including respiratory and enteroviruses. Lesions may coalesce, the tongue may become red and oedematous, and pain may interfere with oral intake.
Lesions appear elliptical, with the long axis running parallel to skin lines, and may be asymptomatic or painful. It is necessary for the parents to educate themselves over what a rash is and the major causes of fever and rash in toddlers so that proper medical treatment is taken. Doctor should be called when a spreading pattern of rash is seen and fever is also persistent. If a child develops shivering during the bath, the temperature of the bath water should be raised. Erythema infectiosum is most commonly a disease of children aged 5 to 15 years, but it can occur at any age. The rash is more prominent with increased skin perfusion, such as occurs in a warm environment, with sunlight exposure, with feeding, or with exertion. Besides rash, fever, swollen glands, pus dots, vomiting and appetite loss are common symptoms.
Unlike other viral infections, roseola occurs throughout the year without seasonal variation. Maculopapular lesions subsequently appear on the hands and feet (Figure 2); these progress to vesicles and then ulcerations.
