Little data on the investigation has yet been released. As of 8 April, 1271 cases have been notified, of which 1206 in Guangdong Province. The remaining 65 cases were notified in six other provinces of China. Sixty five deaths have been officially reported, 45 of which occurred in Guangdong Province.

According to the health authorities there is currently no evidence of transmission in the general population, all cases having being associated to exposure while travelling in an affected area or directly exposed through contacts with a patient (family members or medical staff).

United States
Only one case definition, for suspected cases, is currently being used in the United States (US) (http://www.cdc.gov/ncidod/sars/casedefinition.htm). Therefore the cases reported in the US are not comparable to those reported in other countries. As of 8 April, 148 suspected cases had been notified in thirty states. Although very little information about these cases has been released, only 27 of the 115 cases notified up to 4 April presented clinical signs of pneumonia.
