The UK Health Security Agency (UKHSA) has alerted the public about an infectious disease that could escalate into a serious condition if not properly treated. On Friday, the government health body took to X to highlight five key symptoms that warrant attention.

The UKHSA stated, “Scarlet fever is prevalent among young children and is typically mild. However, it’s crucial to seek treatment to prevent complications. If you notice any of the symptoms listed below, reach out to your GP practice.”

The symptoms outlined in a shared graphic include a bumpy rash, high fever, sore throat, a “strawberry” tongue, and swelling. NHS guidance further explains, “Scarlet fever is a contagious illness that mainly affects young children and can be effectively treated with antibiotics.”

Early indications of scarlet fever may mimic flu-like symptoms, such as a high temperature, swollen neck glands, and a painful throat.

Approximately 12 to 48 hours later, a distinctive rash may appear, characterized by small, raised bumps that give the skin a texture similar to sandpaper.

A white coating may also develop on the tongue, which eventually sheds to reveal a swollen, red surface covered in small bumps—commonly known as “strawberry” tongue.

The symptoms present identically in both children and adults, though the condition occurs less frequently amongst grown-ups, reports

Should you contract scarlet fever, your doctor will prescribe antibiotics to aid your recovery, minimise the risk of developing more severe complications – such as pneumonia, and decrease the likelihood of transmitting the infection to others.

See a GP if you or your child:

• have scarlet fever symptoms
• do not get better in a week (after seeing a GP)
• have scarlet fever and chickenpox at the same time
• are ill again, weeks after scarlet fever got better – this can be a sign of a complication, such as rheumatic fever
• are feeling unwell and have been in contact with someone who has scarlet fever

However, you should always contact the GP over the phone to check first, due to the contagious nature of Scarlet Fever.
