C. and 62°

C., wherein said device comprises at least one primer system capable of producing an amplification product diagnostic for an SARS coronavirus, and wherein each amplification product, when produced, is between 100 and 400 nucleotides in length.

2. The device of claim 1, wherein each of said locations is a chamber.

3. The device of claim 1, wherein each of said locations is a well.

4. The device of claim 1, wherein the primers of each primer system are between 23 and 27 nucleotides in length.

5. The device of claim 1, wherein the primers of each primer system have a theoretical melting temperature between 59°

C. and 61°

C.

6. The device of claim 1, wherein said housing comprises additional locations, wherein each of said additional locations contains a primer pair.

7. The device of claim 6, wherein at least one of said additional locations comprises a primer pair capable of producing an amplification product from human nucleic acid.

8. The device of claim 1, wherein each of said locations comprises an intercalating dye, and wherein each amplification product, when produced, is labeled with said intercalating dye.

9. The device of claim 8, wherein said intercalating dye is a green fluorescent dye.

10. The device of claim 8, wherein said intercalating dye is SYBR Green, LC Green, or SYTO9.

11. The device of claim 1, wherein each amplification product, when produced, is between 100 and 300 nucleotides in length.

12. A method for detecting an SARS coronavirus within a sample, wherein said method comprises:

(a) performing a nucleic acid amplification reaction using said sample as a source of template and a diagnostic device, wherein said device comprises a housing having a plurality of locations, wherein each of said locations contains a primer system, wherein the primers of each primer system are between 18 and 28 nucleotides in length and have a theoretical melting temperature between 58°

C. and 62°

C., wherein said device is capable of producing an amplification product diagnostic for an SARS coronavirus, and wherein each amplification product, when produced, is between 100 and 400 nucleotides in length, and

(b) determining which locations of said device contain a primer system that resulted in the formation of amplification product, thereby detecting an SARS coronavirus.

13. The method of claim 12, wherein said sample is a mucus sample obtained from a human.

14. The method of claim 12, wherein each of said locations comprises an intercalating dye, wherein each amplification product, when produced, is labeled with said intercalating dye, and wherein determining which locations of said device contain a primer system that resulted in the formation of amplification product is based on a signal from said dye.

15. The method of claim 12, wherein said amplification reaction is performed in a thermal cycler device configured to receive said diagnostic device.

16. The method of claim 12, wherein said determining step (b) is performed in using a dye reader device configured to receive said diagnostic device.
