TABLE 2. Technologies Used to Combat Past Pandemics.

S.No.	Recent Pandemic	Technology used with their use cases
1	SARS-CoV-2	The Shanghai Institute of Technology and Physics have created an infrared sensor that can measure an individual’s temperature without physical contact. The sensor assisted with finding broad and simple application to check the spread of SARS outdoors, for example, in railroad stations, air terminals, and harbours. It was seen as a ready to forestall cross-disease by checking the patient’s temperature [19].
		Emergency clinics in Taiwan utilized the access network processing innovation, which was created by the Futures Laboratory at Argonne National Laboratory (Argonne, IL, USA) to share and safely store X-beam pictures and clinical data about patients. The matrix permitted therapeutic services experts to distantly see records and team up on analyzing and making clinical choices. It associated the medical clinics with one another, and with the WHO and the US Centers for Disease Control [20].
		Singapore’s DSO National Laboratories has built up a program that models the spread of SARS utilizing software models of PC security programs that track PC infections across systems. The framework included different information about the population, such as, age, well-being status, and recurrence of contact with others into an electronic stream diagram that indicated how every individual connects with others. The factors were even adjusted to exhibit how changes may influence the spread of SARS [20].
2	MERS-CoV	During the MERS emergency, Singapore General Hospital presented an online physiotherapy program permitting physical advisors to distantly screen patients in their homes. While utilizing the webcam, patients were made to speak with their advisors, who can, thus, show their patients new activities and give them input on their advancement [21].
		Sunday Communications, a Hong Kong cell phone provider, provider clients with a notification service if they are close to contaminated areas. Clients that subscribed had their telephones tracked and would be notified by SMS at locations (within 1 km) where SARS cases were reported. It conclusively demonstrated that this framework forestalled MERS cases later [21].
		In Munster, the medical clinic utilized its ongoing finding framework identifications close by Amazon EMR’s that encouraged all emergency clinic staff, patients and guests to determine who had come into contact with the tainted patient. This innovation was enhanced by the emergency clinic’s video observation framework to guarantee no contact with the patient was neglected, as indicated by the report [22].
3	Swine Flu Influenza	A Korean based organization utilized a FluChip innovation to keep patients out of the emergency clinic and hold space for individuals who are genuinely in worse conditions utilizing chatbots on the medical clinics’ sites to help concerned patients decide if their side effects are likely associated with the swine flu infection and their hazard level. It associated high-hazard people with the side effects reported to ensure the correct degree of care. If the framework recognized somebody in the ER with an affirmed flu infection case or expected case dependent on pandemic hazard, those patients are provided technology for remote monitoring including pulsometers and thermometers to follow their side effects from home. The data assembled was then revealed through the telehealth platforms, and nurses worked nonstop to ensure the manifestations do not advance [23], [24]
		Another methodology was applied by the Swedish organization MedDay, which recommended that individuals enter side effects into PDAs or cell phones, which would remotely transmit their data and subsequently, could aggregate and screen this information. The organization asserted that this could be utilized as an initial notice framework across the nation for episodes of maladies, synthetic assault, or different ailments [25].
