Notes:

Local transmission has occurred when one or more reported probable cases of SARS have most likely acquired their infection locally regardless of the setting in which this may have occurred. If no new locally acquired cases are identified 20 days after the last reported locally acquired probable case died or was appropriately isolated, the area will be removed from this list.

Pattern A
Imported probable SARS case(s) have produced only one generation of local probable cases, all of whom are direct personal contacts of the imported case(s).

Pattern B
More than one generation of local probable SARS cases, but only among persons that have been previously identified and followed-up as known contacts of probable SARS cases.

Pattern C
Local probable cases occurring among persons who have not been previously identified as known contacts of probable SARS cases.

Pattern Uncertain
Insufficient information available to specify areas or extent of local transmission.
