Introduction
[7][7]
In 2005, the International Health Regulations (IHR) declared that a global network of national health
systems should be established that wouldto facilitate coordinated defence against public health threats
and that could ensure the security of international public health. Four areas of work to achieve the
envisioned network have been established:
a) 1) strengthening national prevention capacity;
b) 2) introduction of global alert &and response mechanisms;
c) 3) containment of specific threats; and
d) 4) travel and transports.
With the first case reported on 31 December 31, 2019, the WHO declared COVID-19 as a pandemic in
[6] [6]
March 2020 . The lack of effective vaccines and treatment created a crisis that has seen a significant
number of confirmed cases and deaths worldwide. The pandemic has imposed enormous pressure on,
and, in some countries, paralyzed public health systems, resulting in shortages of personal protective
equipment (PPE), extracorporeal membrane oxygenation (ECMO) machines, hospital beds and medical
personnel.
Each country has implemented various measures to block infection spread at entry points to the country,
which has required tremendous resources. Asymptomatic cases and long incubation periods challenge
infection prevention and control capacities of health care institutions and public health agencies.
A self-symptom checker app for a pandemic enables individuals to record and report pandemic-related
symptoms, to provide information on screening test sites and to offer consultation channels that link
them to health experts for disease spread containment.
The self-symptom checker app is designed to act as a frontline defence that enables isolation and
quarantine of potentially infected individuals.
This document provides interested parties with guidance to support the development of applications for
self-monitoring of symptoms to support screening. Self-monitoring applications maycan be used to
support screening in businesses as well as border entry to contain the spread of infection and provide
critical information to health care providers to provide appropriate care.

when considering a self-symptom checker app.

Functional requirements for self-symptom checker app
1 Scope
This document specifies functional requirements for a self-initiated disease symptom checker app to be
used for early screening and control of pandemics such as COVID-19.
There are four functional components specified in this document:
1) 1) self-registration (Clause 7.1.1); see 7.2);
2) 2) symptom checking (Clause 7.2); see 7.3);
3) 3) guidance on screening stations (Clause 7.3); see 7.4);
4) 4) health consultation (Clause 7.4).see 7.5).

4 General
To build or enhance the capacity to monitor and manage the spread of the disease at the points of entry
and onward, the following actions, at a minimum, should be taken:.
— — To maintain timely communication with visitors/entrants: Itit is an onerous task to contact
entrants, due to unanswered calls and/or phones being offline. This incurs delayed quarantine and
extra personnel to manage connection with entrants.
— — To monitor the entrants’ health status: Provisionprovision of information to entrants of public
health control measures including quarantine and monitoring.
— — Information technology (IT) and infrastructure to support communication and screening
applications: Technologytechnology can enhance our response to pandemic management in a very
significant way. For example, it is possible for disease-pertinent symptoms of an entrant to emerge
after clearance from the point of entry due to a latent state of the virus. With the help of, for example,
a smart phone-based application, it is made possible to track, monitor and manage the health of the
entrant.
The purpose of this document is to provide guidelines towards the development of technology-based
symptom screening applications to improve the efficiencies of infection containment practices.
5 The self-symptom checker app
5.1 General
Four core functional components of the self-symptom checker app are described in Figure 1.Figure 1.
Each functional component comprises a set of functions, each of which executes specific tasks.
The specific tasks of each functional component of the self-symptom checker app are as follows: .
— - Self-registration: after the self-symptom checker app has been installed on the smartphone, tablet
or personal computer of the individual, he/she shall register himself/herself to use the self-symptom
checker app.
— - Symptom checking: the individual shall record and report through the self-symptom checker app
any symptoms he/she has experienced.
— - Guidance on screening stations: the individual maycan at any time search and contact nearby
screening test sites, locations of which are determined by the GPS service, or other positioning service
available, of the device owned by the individual.
— - Health consultation: the individual maycan contact health experts through available communication
channels, such as chatbot, mobile messaging application or email.

6 External services and applications of the self-symptom checker app
The self-symptom checker app is the central application upon which either optional or external services
and applications, or both, can operate (see Figure 2).Figure 2).
For example, national health authorities, subject to user consensus, can gain access to demographic and
symptomatic data about the individuals who have exhibited potential symptoms, and reach out pre-
emptively to them for test and quarantine. State or national health centres can receive information about
the individuals who have been exhibiting symptoms for two or more days consecutively and instruct
them to visit a screening test site.
NOTE Local, regional or national guidelines on patient (or personal) information can apply.
