Actions that reduce the likelihood of disease exposure and limit transmission, assure the public of the ability to maintain domestic safety and security, advise the public to curtail non-essential travel and communal activities while preparing for implementation of communit

It can also play an important epidemiological role in defining vi ISO 2017 All rights reservedPD ISO/TR 13154:2017ISO/TR 13154:2017(E)the geographical
10、boundaries of an outbreak. A screening thermograph complying with IEC 80601-2-59 is a non-contact, accurate and repeatable means of quickly screening individuals for fever when proper procedures are followed.International experience has demonstrated numerous instances of noncompliance with the Inter
11、national Standard and the recommendations of the first edition of this document, as well as Internet postings documenting inappropriate use of radiometry and infrared cameras. It should emphasized that the efficacy and utility of this technology is contingent on the use of both equipment and protoco
