"Dr. Liu, are there any new results?"
Seeing Liu Banxia rushing back, the child's father asked nervously.
"Can you recall if your car has recently hosted any foreign guests?" Liu Banxia asked.
The child's father was taken aback. After thinking carefully, he shook his head. "No foreigners, they're all from our country. Besides, I don't go to the airport much; the competition is too fierce there. I mostly drive around the city."
Liu Banxia frowned. "Are you sure? Please think carefully again."
Still, the child's father decisively shook his head. "If there were, I definitely wouldn't forget. Are you saying Yanyan's disease is a foreign one?"
"Right now, it's merely our conjecture because we've never encountered symptoms similar to what Yanyan is exhibiting. We'll proceed with further screening to see if it's some kind of parasite," Liu Banxia said.
