Total estimated cost for 48,373 cases		$104,486		$88,522	$15,963

Costs per event rationale as follows.

[a]$0.78 for ORASEL and $2.00 for consultation=$2.78 or $0.35 for ORS-Zinc plus $1.50=$1.85.

[b] $2.00 for care seeking plus $1.35 for household cost =$3.35 or $1.50 for care seeking plus $1.28 for household cost=$2.78.
