After a child recovers from pneumonia, platelet counts may sometimes increase. This is often due to the natural rise in platelets during the infection period, which helps the body fight off viral infections. Following successful treatment and recovery from pneumonia, platelet levels usually return to normal within a relatively short time. Parents need not be overly concerned about this. However, if platelet counts remain elevated for an extended period after recovery, it should be taken seriously. It is advisable to promptly bring the child for a blood test to rule out any other potential health issues and ensure the child's well-being and safety.
