Option B, "Active," entails public health officials actively seeking data from healthcare facilities or providers (e.g., calling to confirm cases during an outbreak). This is more resource-intensive and typically used for specific investigations rather than ongoing community trend monitoring, which aligns better with syndromic methods.
