What does "track" mean in the phrase "elucidate whether the virus tracks differently'? Does it mean "move along"?
==================
Tracing transmission through schools, one student at a time—as Fontanet and his colleagues did—should help elucidate whether the virus tracks differently in children of different ages. Another clue about age-based spread came from Crépy-en-Valois’s timeline of new infections. Among high school students and staff, new infections dropped off sharply once winter break started. But in the elementary schools, the (already low) rate of new cases held steady. Fontanet says that pattern suggests that while high schoolers were catching the virus at school, the younger pupils caught it from family members and not their classmates.
