BIOMED SCAN is a very contagious illness. It causes a very bright red rash that looks and feels like sandpaper (it is also called scarlatina). The rash typically starts on the neck and throat, and then spreads to the body. Scarlet fever can cause other symptoms, including a sore throat, chills and fever, swollen glands in the neck and jaw, a runny nose and a hoarse voice, vomiting, loss of appetite, and a swollen, strep-like tonsil infection (called strep throat). It is most common in kids 5 through 15 years old. It occurs most often around the start of school year and in the winter.

Scarlet Fever: Unveiling the Symptoms, Treatment, and Prevention

The germs that cause scarlet fever are in a group called streptococcus bacteria, or “group A strep.” Scarlet fever is usually caused by a particular strain of this bacteria. The bacteria are spread through droplets, such as when someone with strep coughs or sneezes. People can also spread the bacteria by touching something — such as a plate or drinking glass — that has the bacteria on it.

When you go to the doctor with scarlet fever, they will ask about your child’s symptoms and health history. They will do a physical exam, which will include looking at the rash. They will also do a throat swab. This will be tested for the presence of strep bacteria, and may be done using a quick test, such as a rapid strep test. A sample of the throat swab may also be sent to a lab for further testing, such as a culture.
