Streptococcal infections in children mostly occur from 6 months of age to 3 years old, with more incidences in winter and spring, often manifesting as repeated fluctuations in body temperature around 38℃. In general, if the symptoms are mild and the body’s immunity is strong, the earliest recovery can be about 1 week; if the condition is more serious and the body is poor, it can show a long-term low fever of 1-2 months, and some of them can have complications such as purulent tonsillitis and acute glomerulonephritis, etc. There is generally no exact recovery time for this condition, and there are large individual differences. Children who develop streptococcal infections should be seen by a hospital pediatrician in a timely manner to avoid delays and health hazards.
