Definitions

  • the present invention relates to contact tracing technology. More specifically, it relates to a system for determining a contamination condition of a transportation means due to infected individuals accessing said transportation means, according to the preamble of claim 1.
  • contact tracing is an important factor in infectious disease control. Specifically, contact tracing is the process of identification of people who may have come into contact with an infected individual and is carried out in order to isolate the infected individuals and reduce the spread of the infection in a population.
  • Digital contact tracing is a method of contact tracing relying on tracking systems based on mobile devices, to determine contact between an infected patient and a user. Examples of digital contact tracing are the applications for smartphones developed during the COVID-19 pandemic.
  • a user In a centralised report processing protocol a user must upload their entire contact log to a health authority administered server, where the health authority is then responsible for matching the log entries to contact details, ascertaining potential contact, and ultimately warning users of potential contact.
  • anonymous decentralized report processing protocols while still having a central reporting server, delegate the responsibility to process logs to clients on the network. Tokens exchanged by clients contain no intrinsic information or static identifiers. Protocols using this approach have the client upload a number from which encounter tokens can be derived by individual devices. Clients then check these tokens against their local contact logs to determine if they have come in contact with an infected patient. This approach has major privacy benefits.
  • Digital contact tracing is more effective than traditional methods of contact tracing if it is used by the majority of the population and in as many as possible situations of their life.
  • a drawback of current contact tracing applications is that they are installed uniquely in smartphones and are able to trace only close contacts between people.
  • the types of contacts that are relevant for public health management may vary with the disease because of differing modes of transmission thereof.
  • blood-bome infections anyone who could have been exposed to the blood of an infected individual need to be monitored.
  • respiratory diseases such as the Covid-19 pandemic, not only people coming close to each other but also people touching a recently contaminated object or spending a significant amount of time in the same contaminated environment are relevant.
  • the object of the present invention is therefore to provide an enhanced contact tracing technology, and specifically to provide a contact tracing technology that extends to monitoring possible contamination of transportation means.
  • the present invention is based on replicating the functionality of a contact tracing application on board a transportation means, such as a vehicle, whereby the transportation means acts as a smartphone or like personal mobile device.
  • the contact tracing application on board the transportation means does not monitor the possible infection of a user, because he/she has been in close contact with an infected individual, but the possible contamination of the transportation means because it has hosted an infected individual.
