1/ You can do very good contact tracing, get good information and connect the dots if you do it in a standardised way with the same software nationwide. https://twitter.com/shaunscapades/status/1290245493956608002">https://twitter.com/shaunscap...
2/ CT (Contacttracer) need to sit down with the IP (infected person) trace all E (events) where IP met people and put them with the SW (software) in a DT (database).
3/ If CT guarantees anonymity, explains importance of honesty and praises the IP& #39;s contribution to contain the disease, return will be quite good. E need to be identified with time an place (=ETP). It is especially important to define ETP where many People meet.
4/ SW (Software) must be able, with help of People monitoring it, to build a grid of ETP from all IP. SW then can calculate probabilities on which TP transmission occur.
5/ Data Protection must be absolute; every CT and any Person having access to SW and DB must be subjected to absolute medical secrecy and an IP& #39;s identity is never allowed to be released to any other person than CT or the doctors who care for him.
6/ @SwissCovid19STF should urgently elaborate new policy brief about how Contracttracing is best performed including also collection of useful data in a standardised way.
7/ This will certainly contain strong recommendation for standardisation and for @BAG_OFSP_UFSP @EDI_DFI to take lead over cantons @GDK_CDS. Competition for SW can be hold. SW must be simple, reliable and able to run on most used PC-Systems, APP for CT can be added.
8/END
Need for such solutions was foreseeable since the beginning of the epidemic. Not having done it so far shouldn& #39;t hinder anybody to invest himself now even stronger.
I am very busy today in my practice an can react to feedbacks only late tonight.
