Children under the age of two generally have lower immunity and are likely to develop diseases that can break through their baby's immune system and cause strong reactions. Childhood rash is one of them, which usually has a rapid onset and strong disease reactions. Blood testing is a common examination method for children with low language expression ability. Below, the editor will introduce to you how to determine a child's rash through blood testing.
How to determine infantile rash by blood test
Generally, blood tests can only detect viruses and cannot determine whether a child has a rash. White blood cells will increase and decrease after the onset of the disease. If the fever persists, a combination of physical antipyretic and antipyretic drugs can be used to cool it down. Once the fever subsides, the rash will appear immediately to determine whether it is a child's rash.
Clinical manifestations of infantile rash
1. Fever: incubation period of 1-2 weeks, with an average of 10 days. Sudden onset of high fever without prodromal symptoms, with a body temperature of 39 ℃ to 40 ℃ or above, and may be accompanied by convulsions in the early stages of high fever. Except for a lack of appetite, the general mental state of the affected children does not show significant changes. However, a small number of children may experience nausea, vomiting, coughing, scleritis, swelling around the mouth and hematuria, and a very small number may experience drowsiness, convulsions, etc. Mild congestion of the throat and tonsils, as well as mild swelling of lymph nodes in the head, neck, and occipital regions, manifested as high fever that is not commensurate with mild symptoms and signs.
2. Eruption: After a fever of 3-5 days, the fever suddenly decreases and the body temperature returns to normal within 24 hours. At the same time or later, the rash appears as scattered red papules with a diameter ranging from 2-5 millimeters. They fade under pressure and rarely merge. The rash usually first appears on the face, neck, and trunk, and then gradually spreads to the proximal limbs. After 1-2 days, the rash subsides without leaving any trace, shedding or pigmentation. Some children may experience redness on the palate in the early stage, and the rash does not require special treatment and can resolve on its own.
3. Other symptoms include eyelid edema, anterior fontanelle protrusion, runny nose, diarrhea, decreased appetite, etc. Some children have swollen lymph nodes in the neck.
I believe that after reading this article on the clinical manifestations and diagnosis of infantile rashes, everyone has gained a better understanding. Parents must help their babies gradually improve their immune system in this world full of various viruses and bacteria, so that they can avoid serious harm when accidentally attacked by these harmful microorganisms.
