Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In exceptional circumstances, when a technical committee has collected data of a different kind from that
which is normally published as an International Standard (“state of the art”, for example), it may decide by a
simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely
informative in nature and does not have to be reviewed until the data it provides are considered to be no
longer valid or useful.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TR 13154 was prepared by Technical Committee ISO/TC 121, Anaesthetic and respiratory equipment,
Subcommittee SC 3, Lung ventilators and related equipment, and Technical Committee IEC/TC 62, Electrical
equipment in medical practice, Subcommittee SC D, Electromedical equipment.

Introduction
[1] [2]
This Technical Report was derived, in part, from SPRING Technical Reference 15. The SPRING Technical
[6] [7] [10] [12] [13] [16]
Reference was created as result of the Singapore experiences during the SARS epidemic.
Pandemics of influenza have swept the world from time to time throughout history, including three times in the
last century. They caused widespread illness, large numbers of deaths, notably among children and young
adults, and huge societal disruption, concentrated in just a few weeks. There is currently rising concern that a
new influenza virus with pandemic potential will emerge and spread, and a further pandemic can be expected.
It is not known when that will be but the consequences, whenever it occurs, will be serious, with around a
quarter of the population possibly affected. This could be over one or more cycles, each lasting around
three months. See Reference [10]. It should be noted that current estimates indicate that it will take
approximately five months to develop, produce and distribute a pandemic vaccine following the declaration of
a pandemic and isolation of the pandemic virus. See Reference [12].
The prime objectives of pandemic planning are to save lives, reduce the health impact of a pandemic and
minimize disruption to health and other essential services, while maintaining business continuity as far as is
possible and reducing the general disruption to society that is likely to ensue, serious though this will be.
Strong leadership, organization and co-ordination, and clear lines of accountability and communication will be
key to preparing for, and responding to, a pandemic.
The ability to limit the spread of a pandemic disease, target public health interventions, and limit the
unintended consequences of these actions will be greatly enhanced by the widespread availability of cost-
effective screening tools for influenza viruses such as rapid diagnostic tests. Early outbreak detection with
continued surveillance of travellers and the institution of appropriate measures, including social distancing,
isolation of infected individuals, quarantine of suspected cases or treatment with antiviral medication, can help
delay or limit the spread of a virus once a case occurs. Well-coordinated international implementation of entry
and exit restrictions is an important component of an effective global response to contain cases and prevent a
pandemic. All countries should prepare to implement steps to limit spread, including local, regional and
national entry and exit restrictions based on veterinary and health monitoring, screening and surveillance for
humans, animals, and animal products, and information-sharing and cooperation to manage borders. See
Reference [5].
Influenza is not the only possible pandemic disease. SARS, tuberculosis, anthrax, MRSA and other biological
or bacterial agents can cause a widespread pandemic. The sources of such diseases can be naturally
occurring, accidental releases or the result of subversive activities.
Individual screening of all persons entering a country, for influenza-like illness and risk factors for infection
with a pandemic strain, will help minimize the likelihood of transmission. However, such screening is
challenged by a lack of sensitivity (e.g. asymptomatic infected individuals may not be detected) and specificity
(e.g. many individuals with influenza-like illness will not be infected with a pandemic strain). The typical
incubation period for influenza is two days, and infected persons with influenza may be contagious for 24 h
prior to the onset of symptoms. Other possible pandemic diseases have longer incubation periods. Since
some asymptomatic travellers who are incubating a disease may become symptomatic en route, overall
screening effectiveness can be improved by adopting layered pre-departure, en route and arrival screening
measures. The policy of layered screening measures should apply to all in-bound travellers from affected
areas, but the characteristics of the outbreak, including the rapidity of spread, may make it necessary to
implement this screening at all international airports from which passengers originate. In addition, development
of rapid diagnostic tests can dramatically change our ability to screen effectively. See Reference [5].
During the outbreaks of severe acute respiratory syndrome (SARS) in 2003, internationally agreed measures
designed to restrict the movement of people possibly infected with SARS were instituted and were assessed
by WHO to have greatly contributed to bringing the disease under control.
ISO/TR 13154:2009(E)
Influenza is more infectious than SARS, is most infectious early in the course of the disease (and possibly
even before symptoms begin), and has a much shorter incubation period (one to three days). These important
differences make it unlikely that similar interventions will do more than delay or slow the transmission of
pandemic influenza at best, but this may still be deemed useful. Possible measures include:
⎯ providing travel advice on travel to and from affected countries;
⎯ providing health information for exiting and returning travellers;
⎯ providing health screening at ports of entry and exit; see Reference [15].
In a severe pandemic, absenteeism attributable to illness, the need to care for ill family members and fear of
infection may reach 40 % during the peak weeks of a community outbreak, with lower rates of absenteeism
during the weeks before and after the peak. Certain public health measures (closing schools, quarantining
household contacts of infected individuals) are likely to increase rates of absenteeism. 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 community disease containment measures as epidemic spreads, are important public
policy objectives. See Reference [5]. To support these objectives, a screening thermograph can be useful to
separate potentially infectious individuals from others in pandemic situations in locations such as:
⎯ entrances to hospitals and clinics, including emergency rooms;
⎯ entrances to critical infrastructure facilities;
⎯ entrances to workplaces;
⎯ entrances to schools;
⎯ entrances to government buildings, including police and fire stations;
⎯ public transportation.
A screening thermograph should be an element of the layered screening process for those diseases
specifically associated with elevated fever. It can also play an important epidemiological role in defining the
geographical boundaries of an outbreak. A screening thermograph is a non-contact, accurate and repeatable
means of quickly screening individuals for fever when proper procedures are followed.
NOTE The requirements for a screening thermograph are found in IEC 80601-2-59.
