What Causes Petechiae?

Scarlet Fever

Scarlet fever can occur as a secondary illness in individuals with strep throat. The condition creates a vivid red rash that covers the majority of the body. This isn't necessarily petechiae, but it can look extremely similar and be easily mistaken for it. Nearly every case of scarlet fever includes the rash, a sore throat, and a concerningly high fever. Children between five and fifteen years old are most susceptible to the condition. In the past, scarlet fever was a serious enough illness to be deadly or permanently disabling. Modern antibiotic regimens have greatly reduced the seriousness. But failing to treat scarlet fever can cause the body to develop issues that damage the kidneys, heart, and other organs. If individuals have a rash that looks like petechiae alongside strep throat symptoms and a high fever, they need to be seen by a doctor immediately. The longer patients go without treatment, the higher their risk of developing serious complications. The patient's tongue might also be bright red and look bumpy, like the texture of a strawberry.
