MS-1658

A 5-year-old boy, Max, is brought to the pediatrician by his father who is worried about his son’s health over the past 3 days. The father reports that Max has been experiencing a loss of appetite, complaining of joint pain and headaches, and is generally not his usual self. Despite his love for school, Max seems content with staying home as he has been playing with his new puppy and has a few scratches. What is the probable pathogen responsible for Max’s symptoms?
