How to distinguish between petechiae and rash? If the rash subsides, it becomes paler or paler, and the petechiae remain the same color. There are many reasons for the appearance of petechiae, some are harmless and others are serious, so discuss these red spots with your dermatologist.
Rash
It may seem all-encompassing, but rashes can be caused by medications, irritants (such as insects), or infections. Rashes are often the cause of spotting in babies. The most common medications that cause rash include antibiotics, NSAIDs, and anticonvulsants.
Irritants are difficult to identify, but dust mites, latex, and animal dander can cause allergic rashes. Certain cosmetics, herbs, and nickel may be to blame. Many infections, including viral, bacterial, and fungal infections, can cause red spots on your skin. These infections include chicken pox and rubella, which we will discuss in more detail in the next section.
