Question 9 A 6-year-old girl was bitten by a friend’s dog. Her mother asks the clinician if the child needs anti-rabies treatment. Which of the following should the clinician advise?

 “Anti-rabies treatment must be started immediately.”

 “Wait until you have observed the animal for 2 weeks to determine if it is rabid.”
