Bright red rash that covers most of the body is the characteristic feature of this infection. Sore throat and fever are commonly seen during this infection. Scarlet fever is commonly seen in children from 5 – 15 years of age.

3 Causes

Bacterial intoxication is the main cause of scarlet fever. This bacterium releases a toxin which damages the human tissues and gives the typical appearance of scarlet fever rash and red glossy tongue.

The infection spreads from person to person by the means of droplets expelled from an infected person during coughing or sneezing. Incubation period(the time required for the bacteria to grow in number but not show any typical symptoms) is usually from two to four days.

4 Making a Diagnosis

Diagnosis of scarlet fever starts with physical examination that includes:

  • Checking the condition of throat, tonsils and tongue.
  • Palpating and checking for the enlarged lymph nodes.
  • Accessing the features of rash.
  • Throat swab: if strep throat is suspected in such case swab from the throat can be taken and sent for lab diagnosis.

Tests to diagnose the strep bacteria are important because a number of conditions can cause similar signs and symptoms but require different treatments.

If there are no traces of strep bacteria, then most probably some other bacteria are involved.

5 Treatment

Antibiotics are the first line treatment for scarlet fever. Course of the medication must be completed.

If the course was not completed according to the prescription, then there are higher chances of reoccurrence and further complications such as systemic toxicity.

6 Prevention

Proper hygienic conditions must be maintained in order to prevent scarlet fever. The following steps must be followed:

  • Washing hands- washing hands thoroughly for two minutes before and after eating food and using toilet with warm soapy water.
  • Sharing food- don’t share dining utensils and food with other children in school.
  • Protecting airways- as this fever spreads through airways, using a mask while in contact with infected people may help.
