The witnessed world pandemic caused by the deadly disease known as COVID-19 is a new respiratory infectious illness also called Coronavirus reported on December 31 by the World Health Organization . It is a global health emergency issue that put the entire world into despair. The disease spread mainly through humans when they come close to each other (about 6 feet) and another through respiratory droplets from an infected person’s cough or sneeze. Though many researchers, scientist is putting in their best to ensure that the treatment of this deadly disease is discovered. Furthermore, it was also identified that the symptoms of the disease includes: Fever, Cough and Shortness of breath or difficulty breathing. World governments are at work to establish countermeasures to stem possible devastating effects. Health organizations coordinate information flows and issues directives and guidelines to best mitigate the impact of the threat. At the same time, scientists around the world work tirelessly, and information about the transmission mechanisms, the clinical spectrum of disease, new diagnostics, and prevention and therapeutic strategies are rapidly developing. Many uncertainties remain with regard to both the virus-host interaction and the evolution of the epidemic, with specific reference to the times when the epidemic will reach its peak .
Currently, the therapeutic strategies to deal with the infection are only supportive, and prevention aimed at reducing transmission in the community is our best weapon. Aggressive isolation measures in China have led to a progressive reduction of cases in the last few days. In Italy, in geographic regions of the north, initially, and subsequently throughout the peninsula, political and health authorities are making incredible efforts to contain a shock wave that is severely testing the health system. Though in Nigeria, isolation centers has been put in place where medical doctors are battling day-in-day-out to ensure that the speed of the spread is reduced to its lowest level. It was noted after a critical study on the operations and activities in various isolation centers in the Country that the activities are manually operated, reporting and identifying of infected persons is difficult and hence making it impossible for the medical personnel’s and the government to get accurate data and statistics of the infected persons in the country. Though there are some medical machines used in the diagnosis and treatment of this illness, but the major problem is inability to identify, track and report infected persons of this illness, therefore there is need to design a web based Emergency Information System for Reporting and Tracking of COVID-19 Infected Persons.
This system contribute immensely in the aspect of information gathering, discovery and reporting in the sense that enable people to easily report any suspected case of COVID-19 from a remote location, making it easier for the government to take adequate measure in identifying the person in question, and hence updating accurate information on the records of infected or suspected persons of COVID-19 within the country. In summary, the implementation of this system will provide an enabling platform for companies, public and private organizations and more importantly transportation companies to report suspected persons infected with COVID-19 infectious disease and hence making it possible for tracking and identification of these COVID-19 persons easily.
This paper is organized as follows: Introduction of the paper, related literature, role of information systems in fighting COVID-19 infectious disease, methodology, analysis of the existing system, analysis of the proposed system, new system architecture, use case diagram of the new system, activity diagram of the new system, high level model of the new system, sequence diagram of the new system information tracking, choice and justification of language platform, results and conclusion of the work.

physical modules which include the hardware, software, databases, procedures and personnel. By  computing system is formalized system where collected data are sorted out by several processes, reports, data from numerous sources to provide the needed information and necessary to obtain necessary management decisions. Information system should be centered on the computer data, often collected and stored information automatically by process online.
Role of Information Systems in Fighting COVID-19 Infectious Disease
 noted that an information systems (IS) involve a variety of information technologies (IT) such as computers, software, databases, communication systems, the Internet, mobile devices and much more, to perform specific tasks, interact with and inform various actors in different organizational or social contexts. Of general interest to the field of IS are therefore all aspects of the development, deployment, implementation, use and impact of IS in organizations and society . In respect to the role information system plays in providing a platform for the diagnosis, treatment, tracking, reporting and retrieving of related information’s on the infectious disease called COVID-19. In this research, the researcher noted that information system (IS) is used by various IT organizations like Apple and Google as reported by Stan  designed a contact tracing system using a mobile phone Bluetooth to track infected persons with COVID-19 shown in Figure 2 below.
The companies designed the application in a way that enables public health organizations to keep track of everybody that users of the application come into contact with in a day. Therefore if someone with whom the user comes close with finally test positive after diagnosis, then the application will alert the user so as to take appropriate action. On the same hand, the Centers for Disease Control

and Prevention  of United State of America has activated the Emergency Operations Center (
Furthermore,  designed its blood-based serology immunoassay kit which could help to diagnose SARS-CoV-2 (Virus that cause COVID-19) by analyzing a patient’s immune system and hence watch it response against COVID-19 infectious disease and their platform could be operated manually or automated. In respect to the fight against COVID-19, china adopted some technologies like artificial intelligence (AI), big data, cloud computing, blockchain, and 5G which help to improve the efficiency and management, monitoring, virus tracking, prevention, control, treatment, and resource allocation of the epidemic as reported , some of the designed technologies includes: automated genome-wide testing and analysis platform, temperature measurement technology based on computer vision and infrared technology used in checking body temperature in a contactless, reliable, and efficient manner, big data was used for prediction and early warnings of the disease, analyzing the flow of people and the distribution of materials and designing of Big Data Migration Map which allow people to use their phone to check for the migration trend of the Chinese mainland from the start till date, cloud computing was made free by Alibaba Cloud for public research institutions around the world for free to accelerate the development of new pneumonia drugs and vaccines, Online-Class was in high demand Youku and Ding Talk (an all-in-one platform under Alibaba Group) which allow students to attend class at home. The virtual and secured learning environment was equipped with adequate convenient learning tools, in the other hand, blockchain technology also help to provide maximum security towards making sure that data lose and alteration was not witnessed, and information tracing on corona virus within and outside the country is identified and aborted. In the aspect of 5G, it was used in providing assistance towards management of this deadly pandemic; 5G was used to create live-streaming video and telemedicine systems, remote clinic consultation systems are developed in china and used in total fight against this disease .
In summary, so many technological devices and systems were developed and used in other Counties aside Nigeria as of the time of this research towards fighting this deadly disease, as outlined in section 2.1 of this paper. Hence, the key difference between this work and other existing related studies and adopted technologies on COVID-19 pandemic is outlined in Table 1. Therefore the new system uses a web base technology to proffer accurate and secured information gathering and provision to academic researchers, health professionals, government and developers within the country to fight against this pandemic called COVID-19 in Nigeria.
Table 1. Major difference between the new system and the existing related literatures.
The methodology adopted for the design of the new system was agile model and Unified Modeling Language (UML). The UML was used to model various users’ activities and their privileges on the platform. This model was used because of the emergency of the COVID-19 pandemic; it requires a fast approach towards providing solutions that could help in solving the problem at hand. An agile model allows developers to carry out a project in an iterative approach, open collaboration, and process adaptability throughout the life-cycle of the project. In this approach, repeated visit to every phase of the work is done until its final development is achieved.
The development of the web based emergency information system for reporting and tracking of COVID-19 infectious disease followed the repetition process as shown in the Figure 3 to achieve the desired objectives of the new system.
3.1. Analysis of the Existing System
The existing system of information gathering, tracking and retrieving in Nigeria towards management of the COVID-19 outbreak are handled manually and unprofessional. There was no platform for people to report suspected persons with COVID-19. That is to say, reporting of cases of COVID-19 is done mainly in the isolation centers, and hence most times the law enforcement agencies are not able to identify person that entered in the country either because of bribe or no proper technology to do so. In transportation companies in Nigeria today, people still travel from state to state without proper medical checks for COVID-19, and
Figure 3. Agile model project life-cycle flow.
even if the medical checks are done, fast reporting or call to COVID-19 emergency response team are not fast contacted, therefore, the new system is designed to fill in this gap by providing a platform for private, public organizations, people to provide information on suspected persons with COVID-19 after medical examinations conducted. Furthermore, because recording of infected or suspected persons of COVID-19 is done manually made accurate data storing, retrieving, tracking and update difficult and time wastage sometimes leading to data lose. “There is no how restrictions to accurate data to researchers and technologist will not affect the rate of technological advancement or products development that could assist the medical personnel’s and government fight the corona virus”. It was because of access to this information’s that made china design numerous technological devices that helped manage the disease in their country. Therefore, the researchers urge the Nigerian government to build a data bank or warehouse (if not in existence) and make it open for researcher and technologist to use in building software’s and hardware’s or techniques that could help in managing this deadly disease.
3.2. Analysis of the Proposed System
The proposed system architecture shown in Figure 4 contains all the modules and how they are inter-connected to each other. The proposed system also is composed of two different users; People user and administration as shown in use case diagram in Figure 5. The Use case diagram provides a clear privileges and role of each user on the platform. The new system activity diagram shown in Figure 6 of this research explains the activities of various users on the platform. Once a user visits the platform through the browser, the first point will be the control panel (Home) which can now provide a link for login authentication process to be done. After a successful login authentication process, the user with (People Role) can report a case nor ask questions concerning the pandemic while the user with (Administrator Role) could track for information on the spread, affected or suspected persons with COVID-19 within the country, updating of information on the pandemic, and providing accurate answers to questions asked by people on the issue of the pandemic while Figure 7 outlined the High Level Model (HLM) of the new system and how all modules and

sub-sub-modules are inter-related. Every system must have a style (method) of operation, hence the Figure 8 shows the Sequence Diagram of the new system information tracking, once a successive login is done which will take the user to the dashboard, the dashboard enable user to either to Track a Patient, Answer Question, Update Patient Information and management of the entire system.
· PEOPLE USER: The general public accesses the platform through their mobile phone web browser by entering the URL of the website. Once the interface opens, the HOME of the platform (index.php) displays links to every other module the user wishes to access depending the role and access shown in Figure 9. As a user with this role has ability to report any suspected person with the virus by clicking on the Report Case Module (Report_Case.php) to report a case. Figure 10, shows the COVID-19 Case reporting interface. Also ability for more enlightenment on the issue of COVID-19 could be achieved through the interface in Figure 11, it was identified that people are afraid and are not informed properly on the causes and dangers of this disease, therefore the interface, allow for questions to be asked by the people on the case of this pandemic (Ask_Question.php).
· ADMINISTRATOR USER: Before an administrator could access the dashboard, shown in Figure 12, an authentication of the login details will be done and this authentication will be achieved on the interface (Login.php) shown in Figure 13 after which an access could be granted into the dashboard (Dashboard.php) for other activities. The administrator role allow access to track suspected person by clicking on the module (Track_Case.php) shown in Figure 14 so as to periodically monitor the patient health status. The administrator user is the one with the entire control and management of the system. The admin is privileged to update the system database shown in Figure 15 by clicking on the module (Update_Info.php) at any time to feed in the rightful information, the admin role also click on the module shown in

The administrator user has the role of tracking information on the issue of COVID-19 cases, constant update of the information’s as of when due, providing accurate answers to questions asked by people on the current pandemic and report any suspected case of the pandemic. On the same platform, the people user has some granted privileges such as to report any suspected case of COVID-19 within the country, and ask questions about the disease where necessary.
3.5. Activity Diagram of the New System
The new system activity diagram shown above explains the activities of various users on the platform. Once a user visits the platform through the browser, the first point will be the control panel (Home) which can now provide a link for login authentication process to be done. After a successful login authentication process, the user with (People Role) can report a case nor ask questions concerning the pandemic while the user with (Administrator Role) could track for information on the spread, affected or suspected persons with COVID-19 within the country, updating of information on the pandemic, and providing accurate answers to questions asked by people on the issue of the pandemic.
3.6. High Level Model of the New System
The new system High Level Model (HLM) was designed using the Unified Modeling Language (UML) tool; it was done following the top-down design technique, such that every module, sub-module and sub-sub-module in the system was captured shown in Figure 7 of this paper.
3.7. Sequence Diagram of the New System Information Tracking
The Sequence Diagram of the New System Information Tracking outlines various activities in a sequential order for the administrator user on the platform. The system checks admin (user) login details from the database, if login combination is false, an errorresult is displayed for the user else, a successful message which will take the admin (user) to the admin dashboard where operations as shown in Figures 14-16 and Figure 17 of this paper can be performed. After successive activities on the platform are done by the admin (user), the logout link used to exist from the dashboard.
3.8. Choice and Justification of Language Platform
This section contains the output (results) screen shot of the new System. It shows the implementation phase and to enable the readers to a more understanding on how the new system could be used to report or track cases of COVID-19 in Nigeria. Figure 9 shows the control center (index.php) of the entire system. It is the first interface a user meets after entering the Universal Resource Locator (URL) of the website in the browser.
To effectively report cases of COVID-19 in Nigeria, this interface shown in Figure 10 ensure that all reported case are adequately submitted into the database for immediate action to be taken place.
The administrator of the system also has the privilege to delete irrelevant information’s from the database periodically. This can be achieved through the interface shown in Figure 17.
In conclusion, information systems has been used in all aspect of effective data management, therefore in the aspect of the new identified Corona virus infectious disease was also managed with the developed web based emergency information System for reporting and tracking of COVID-19 Infected Persons in Nigeria. Hence the system was able to store reported cases of COVID-19, questions and answers on the disease were adequately done and store for future reference, monitoring of affected and suspected persons were collected and stored, and lastly the web platform was accessible for every person with availability of computer device either mobile phone or PCs remotely. Hence the authors therefore recommend that this system be adopted by the Nigerian government to help in the fight against Corona virus infectious disease.
