Petechiae are small red, purple, or brown spots caused by bleeding under the skin. Usually, petechiae themselves are not serious, but they can signal an underlying condition that may require medical attention. You should worry about petechiae and seek immediate medical care or see a doctor if you or your child experience petechiae along with any of the following symptoms:
- Fever, especially a high fever (100.4°F or higher)
- Petechiae that spread rapidly or cover a large part of the body
- Confusion or changes in consciousness
- Dizziness or fainting
- Trouble breathing or shortness of breath
- Spots that get bigger or develop streaks under the nails
- Other signs of bleeding or bruising
- Rapid heart rate
- Severe fatigue or lethargy
- Vomiting, nausea, diarrhea, or decreased alertness
These symptoms could indicate serious infections such as meningitis or sepsis, blood clotting disorders, autoimmune diseases, or other life-threatening conditions. It's especially urgent for children who present with petechiae and a fever to get emergency medical assessment. If petechiae appear without a clear cause, persist for a long time, or if you do not know the cause of the spots, it is important to consult a healthcare provider for diagnosis and treatment. In summary, while petechiae can be harmless, they become a concern when accompanied by systemic symptoms or when spreading rapidly, signaling possible severe illnesses that require prompt medical care.
