Abstract

Bioagent surveillance of airline passengers is accomplished by having the passenger walk through a gateway (1) to be exposed to a stream of air (3) that sweeps away any bioagents exhaled by the passenger and/or struck from the passenger'"'"'s clothing. The swept air, including any bioagents, is collected (5, 7) and tested (9) for the presence of any of a predefined list of bioagents; and the presence of a bioagent displayed (10).

Claims

1. A method of non-intrusively detecting the presence of any of a predetermined group of bioagents on or in a person, comprising the steps of:

applying an airstream to the person for sweeping bioagents exhaled by the person or which are present on the clothing of the person downstream;

collecting at least a portion of said airstream from downstream; and

testing said portion for the presence of any of said predetermined group of bioagents.

2. The method of non-intrusively detecting the presence of any of a predetermined group of bioagents on or in a person as defined in claim 1, wherein said step of applying an airstream to the person for sweeping bioagents exhaled by the person or which are present on the clothing of the person downstream, further comprises the steps of:

directing said person to enter and walk through a housing, said housing having an upper side, a walkway, said walkway including passages therethrough, and a blower for blowing an airstream from said upper side of said housing vertically downward toward said walkway, whereby said airstream strikes the head and clothing of said person when said person is present in said housing and exits through said walkway; and

wherein said step of collecting at least a portion of said airstream from downstream, further comprises the step of;

collecting at least a portion of said airstream from downstream under said walkway.

3. The method of non-intrusively detecting the presence of any of a predetermined group of bioagents on or in a person as defined in claim 1, wherein said step of testing said portion for the presence of any of said predetermined group of bioagents, further comprises the step of:

depositing said portion in an automated ELISA apparatus, wherein said automated ELISA apparatus automatically tests said portion for the presence of said predetermined group of bioagents.

4. The method of non-intrusively detecting the presence of any of a predetermined group of bioagents on or in a person as defined in claim 1, further comprising the steps of:

assigning a digital identification number to the person; and

producing a digital photograph of the person.

5. The method of non-intrusively detecting the presence of any of a predetermined group of bioagents on or in a person as defined in claim 4, further comprising the steps of:

assigning a test number to said testing; and

associating said test number with said digital identification and said digital photograph and saving said test number, digital photograph and said digital identification number in a memory.

6. The method of non-intrusively detecting the presence of any of a predetermined group of bioagents on or in a person as defined in claim 1, further comprising the step of:

displaying the result of said step of testing said portion for the presence of any of said predetermined group of bioagents.
