Fever with rash in infants

Fever with rash in infants: What could it mean?

The combination of fever and skin rash is a situation that always requires attention and consultation with a pediatrician. Although the cause may be a relatively harmless viral infection, such a symptom combination can also point to more serious bacterial diseases. Being able to describe the nature of the rash and accompanying symptoms will help the doctor reach the correct diagnosis more quickly.

Most common causes of fever with rash

• Roseola (infant three-day fever). Very common viral infection. Characterized by an initial high fever (39-40°C) lasting 3-4 days while the child feels relatively well. As soon as the temperature normalizes, a fine pink rash appears over the body, which does not itch and resolves on its own within a few days.
• Enteroviral infection (hand-foot-and-mouth syndrome). Characterized by fever and the appearance of a specific rash in the form of vesicles on the palms, soles, and in the mouth.
• Varicella ("chickenpox"). Starts with fever, then a characteristic rash appears that goes through several stages: red spot, papule, vesicle with clear fluid, crust. New rash elements continuously appear.
• Measles. Dangerous viral disease that begins with high fever, cough, runny nose, and conjunctivitis. The characteristic rash appears on day 4-5 of illness, in stages: first behind the ears and on the face, then spreads down the body.
• Scarlet fever. Bacterial infection (caused by streptococcus). Characterized by high fever, severe sore throat ("burning throat") and a fine sandpaper-like rash to the touch.

When is immediate help needed?

Call an ambulance immediately if the rash looks like "stars" or bruises that do not blanch when pressed with a glass (a sign of meningococcal infection), or if the child's condition deteriorates rapidly. For more details on different types of rash, read our guide "Rash in infants".
