Framtida utvecklingsmöjligheter

Precis som koldioxidhalten i luften kan avläsas i ett rum i realtid, skulle det teoretiskt kunna avläsas smittrisk för flertalet olika sjukdomar (olika quanta) i ett rum. Idén bygger på att partikelmätare installeras vid frånluft, tilluft och vistelsezon i syfte att generera värden för ventilationsindex. Någon typ av ljudindikator för att uppskatta aktivitet, och personräknare. Luftflöden, filters avskiljningsförmåga samt rumsvolym är konstant indata som förprogrammeras.

En brist med detta skulle kunna vara att denna apparat kan inte veta ifall någon/några befinner sig i presymptomatiskt tillstånd. Alltså får den basera sig på daglig uppdaterad statistik om hur många nya fall som registrerats i aktuell region. Med antal fall borde grov uppskattning kunna göras av hur stor del av befolkningen som befinner sig i presymptomatiskt tillstånd.
