A fever with a rash in a child can be caused by several illnesses, including chickenpox, fifth sickness, and roseola. These viral diseases can be uncomfortable, but they normally resolve on their own. A rapid rash with a fever, on the other hand, may indicate something more serious, such as a strong medication reaction.

cough, coryza (head cold, fever,
sneezing), and conjunctivitis (red
eyes)—along with a maculopapular
rash

small white spots
that are commonly
seen on the inside of
the cheeks opposite
the molars.They
appear as "grains of

8. Rubella( german
measles)

9. • Rubella, also known as German measles or
three-day measles

(petechiae) on the soft palate
in 20% of patients with
rubella. They precede or
accompany the skin rash of
rubella (German measles) .
They are not diagnostic of
rubella, as similar spots can
be seen in measles and scarlet
fever

11. Roseola

12. • It is caused by human herpesvirus 6 (HHV-6A,
HHV-6B) or human herpesvirus 7 (HHV-7)
• Roseola classically presents with two phases:
fever and rash
• The virus begins with a 3-6 day febrile illness.
During this time, temperatures can peak above
40 °C and children can experience increased
irritability with general malaise
• Once the febrile phase subsides, a rash
develops. In some cases, the rash can present
after one or two days after the fever resolves

13. • The rash is classically described as an
erythematous morbilliform exanthem and
presents as a distribution of soft pink, discrete,
and slightly raised lesions of 2-5mm diameter.
• It classically begins on the trunk (torso) and
spreads outward to the neck, extremities, and
face. This pattern is referred to as a centrifugal
spread.
• Usually, no peeling and itching.
