The story below addresses the animal reservoir for the SARS CoV and shows why its re-emergence in the Shenzhen area from the animal reservoir is likely.

I suspect the following quote was supposed to be 4.5%, but it still provides an important clue on the animal reservoir. The antibody tracing is useful, but the animal virus has molecular changes that may prove to be even more useful. Not only hasn't the antibody data been published, but there is no molecular data, although as Klaus Stohr knows, the sequence data is VERY revealing and includes clues on WHEN the virus emerged.

"About 45 percent of 1,884 market workers in the study had formed blood proteins known as antibodies from infection with the SARS virus. The infection rates varied among the workers, with the highest in poultry workers (18 percent of 124) and slaughterers (17 percent of 35).The study also found infection rates of 5 percent of 116 transport workers and 5 percent of 394 seafood workers.

The tests could not determine when the infection occurred. And the scientists did not learn what symptoms, if any, the workers in the study experienced or pinpoint which animal or animals might have transmitted SARS, Dr. Stöhr said."
