Scarlet fever is back and every parent needs to watch out for these warning signs

 

 

Scarlet fever is a contagious bacterial infection that occurs in children between the ages of 5 and 10. The bacteria in question (at the origin of the signs of angina) secretes a toxin (protein having toxic effects) diffusing in the body and responsible for the cutaneous signs of the disease.

 

++ Symptoms of scarlet fever

 

Incubation (time between contamination and the first symptoms) of the disease lasts 1 to 4 days, sometimes longer.

 

The onset of the disease is sudden, associating fever of over 38.5 ° C, chills, pharyngeal (throat) and abdominal pain, vomiting. These first symptoms are comparable to tonsillitis.

 

The state period then occurs in less than 2 days and is characterized by the occurrence of a rash (we speak of exanthema) and a rash occurring in the mouth and throat (we speak of enanthem).

 

The rash begins in the armpits, at the folds of the elbow and groin and can then affect other parts of the body such as the upper chest, lower abdomen, face (except around the mouth) , and extremities (except the palms of the hands and the soles of the feet). The rash may then be itchy.

The easily recognizable enanthema appears in all cases and will be recognized during the medical examination.

It should be noted that the attenuated forms are the most frequent at present: general manifestations (fever, pain …) less marked, more discreet rash. However, the enanthema remains constant and characteristic.

 

++ The diagnosis of scarlet fever

 

The diagnosis is essentially clinical (epidemic context, characteristic and constant appearance of the enanthema).

 

Examination of the throat finds red sore throat associated with lymph nodes at the angle of the jaw. White at first, the tongue gradually turns red.

Palpation of the pulse finds an increase in heart rate.

Exanthema examination finds hot, dry and rough skin.

Biological examinations do not show specific elements in favor of the infection: increase in the number of white blood cells in the blood.

Throat swabs taken before you start taking antibiotics can show the bacteria. If the doctor is in doubt about the diagnosis, he or she may perform a rapid diagnostic test for angina (RDT). This test is completely painless and very quick. The doctor takes a swab (a kind of large cotton swab) from the tonsils, which he then places in a tube that contains a reagent. A strip is immersed in this liquid. Depending on the color of the strip, the doctor knows whether or not the angina is due to group A streptococcus.
