What this Trial Is About

The goal of this clinical trial is to compare a placebo (a look-alike substance that contains no active drug) with a commonly used antibiotic in children with Mycoplasma pneumoniae (a specific bacterium) induced community-acquired pneumonia. The main question it aims to answer is: Is antibiotic treatment needed in Mycoplasma pneumoniae (a specific bacterium) induced pneumonia? Participants will receive either a placebo or a antibiotic treatment and track their symptoms and vital signs until they are healthy. Researchers will then compare the length of symptoms between the placebo and the antibiotic group.
