Patient's question:
I noticed that my child has a slightly feverish symptom, but at the same time, I saw a few red rashes appearing on the child's body. Initially, I thought it was a high fever, but it didn't improve. Later, I went to the hospital for a thorough examination and found that the child had scarlet fever. What assistance is needed: What should be paid attention to when dealing with scarlet fever?Doctor's answer:
It is an acute respiratory infectious disease. It is characterized by fever, pharyngitis, generalized diffuse scarlet fever-like rash, and desquamation. In later stages, a very small number of cases may experience recurrent cardiac and renal complications.[Pathology and Pathogenesis] The main pathogen is Streptococcus pyogenes (Group A Streptococcus). After the pathogen enters the human body, it causes purulent inflammation in the throat. The toxins enter the bloodstream, leading to toxemia, which induces inflammation in the skin. In severe cases, the liver, spleen, kidneys, myocardium, and lymph nodes may also develop inflammatory conditions. In some patients, 2 to 3 weeks after the onset of the disease, allergic-like lesions may develop in multiple organs throughout the body.
