What if your baby has a cold severe diaper rash and all over his body what could this be?

A child with a severe diaper rash and a cold all over their body may have any of the following conditions.

1. Hand, foot, and mouth disease (HFMD): HFMD is a common viral infection that can cause fever, sore throat, and a rash on the hands, feet, and mouth. The rash typically starts as small, red blisters that can develop into larger, painful sores. In some cases, HFMD can also cause diarrhea and vomiting.

2. Chickenpox: Chickenpox is a highly contagious viral infection that causes an itchy rash of small, fluid-filled blisters. The rash typically starts on the chest, back, and face, and then spreads to the rest of the body. Other symptoms of chickenpox can include fever, headache, and fatigue.

3. Measles: Measles is a highly contagious viral infection that causes fever, cough, runny nose, and red, watery eyes. A rash typically appears 3-5 days after the onset of symptoms and starts on the face before spreading to the rest of the body. The rash can be itchy and may last for up to 7 days.

4. Rubella: Rubella, also known as German measles, is a viral infection that causes fever, rash, and swollen glands. The rash typically starts on the face and spreads to the rest of the body. It can be itchy and may last for up to 3 days. Rubella is particularly dangerous for pregnant women, as it can cause serious birth defects.

5. Scarlet fever: Scarlet fever is a bacterial infection that causes a sore throat, fever, and a rash. The rash typically starts on the chest and spreads to the rest of the body. It can be itchy and may last for up to 7 days. Scarlet fever is treated with antibiotics.

If your child has a cold and a severe diaper rash, it's important to see a doctor to determine the cause and get appropriate treatment.
