What are petechiae and what should you do if you notice them on your or your child's skin?
### What are Petechiae?
Petechiae are tiny red, brown, or purple spots on the skin caused by bleeding under the skin. They can appear in clusters and may look like a rash. Unlike many rashes, petechiae do not turn white when you press on them. They can form anywhere on the body, including the face, neck, chest, eyelids, and inside the mouth.
### Causes of Petechiae
Petechiae can be caused by various factors, including:
- **Infections**: Viral infections (like CMV, flu), bacterial infections (like meningitis, strep throat), and fungal infections.
- **Physical Strain**: Intense coughing, vomiting, childbirth, or heavy lifting.
- **Medical Conditions**: Blood disorders (like leukemia), immune disorders (like ITP), and vitamin deficiencies (like scurvy).
- **Medications**: Certain antibiotics, malaria drugs, seizure medications, blood thinners, antidepressants, NSAIDs, heart rhythm drugs, and sedatives.
### When to See a Doctor
While petechiae are often harmless, they can sometimes indicate a serious condition. You should see a doctor if:
- You or your child has petechiae with a fever.
- The spots are accompanied by other symptoms like trouble breathing, confusion, or changes in consciousness.
### Diagnosis and Treatment
A doctor will examine the rash and may perform blood and urine tests to determine the cause. Treatment depends on the underlying cause:
- **Viral Infections**: The spots usually clear up as the infection goes away.
- **Bacterial Infections**: Antibiotics may be needed.
- **Serious Conditions**: Hospital treatment may be required, and you may need to see a specialist.
### Prevention
To prevent petechiae, take good care of your health:
- Practice good hygiene.
- Avoid procedures that can lead to skin infections.
- Ensure you get enough vitamins.
- Get vaccinated to prevent certain infections.
- Avoid mosquito and tick bites by wearing protective clothing and using insect repellent.
### Home Care
If petechiae are caused by minor incidents like coughing or vomiting, you can manage them at home by resting and staying hydrated. However, it's always best to consult a doctor to rule out serious conditions.
