Common conditions that can cause a skin rash

Fact Checked

There are various diseases that can trigger a skin rash. These rashes typically affect the texture or color in the skin. The exact cause of the skin rash can be determined based on its evident characteristics along with other accompanying symptoms. It is vital to pinpoint and avoid any products that might trigger skin irritation. Oftentimes, certain diseases are the cause of a skin rash.

Skin rash from atopic dermatitis

Atopic dermatitis is a condition that triggers a skin rash. This condition is considered chronic and mainly affects the skin but it is not contagious.

The condition is characterized by an itchy skin rash that results to swelling, redness and cracking of the skin along with drainage of clear fluid, scaling and crusting. Individuals who have the condition often suffer from flare-ups that are followed by phases of remission in which there are no skin rashes.

Atopic dermatitis can vanish entirely as the child grows up but in most cases, those who have the condition during childhood can retain dry skin that is readily irritated. Some individuals continue to experience the distinctive symptoms up to adulthood.

Scarlet fever

Skin rashes
Atopic dermatitis is a condition that triggers a skin rash. This condition is considered chronic and mainly affects the skin but it is not contagious.

Scarlet fever causes a skin rash from infection due to group A Streptococcus bacteria. The condition is characterized by a skin rash and a strawberry-like appearance of the tongue which is commonly seen in children younger than 18 years old.

The skin rash often manifests as small-sized reddened bumps on the stomach and chest but can rapidly spread all over the body. The skin rash is similar to sunburn and has a texture strikingly similar to sandpaper. In some parts of the body, it can appear redder including the armpits, elbow creases and the groin. The rash can persist for about 2-7 days and once it subsides, the skin on the tips of the fingers and toes start to peel.

Pityriasis rosea

Pityriasis rosea can also cause a skin rash among individuals between 10-35 years old, but it can occur at any age. In most cases, the rash can last for several weeks up to several months.

The skin rash will not cause lasting marks or scarring but darker-skinned individuals can end up with lasting flattened brown spots on the skin that later on fade. Even though the condition can develop at any point, it typically occurs during spring and fall. The usual indications include a herald patch that is large in size, slightly elevated and scale-like on the chest, back or abdomen while symptoms of an upper respiratory infection can also manifest such as stuffed nose, headache, mild fever and sore throat.
