Repeat testing of the age groups in which vaccination has not yet been possible (e.g. school-age children) reveal a sharp rise in the positivity rate of the pools examined since school began in comparison to before the summer holidays: from 0.15% to 2.02%. General testing activity is constantly on the rise, increasingly so in companies.

The testing performed at schools and health facilities through the Hirslanden Group’s “TOGETHER WE TEST” platform was resumed on 16 August 2021. In the meantime, the first week of school has also come to an end in further major cantons with which we have contracts. A comparison of the positivity rates of the analysed pools (bulk samples) within the scope of the repeat testing before and after the summer holidays reveals a strong increase:

Important prioritisation of schools

Currently over 90% of analysed tests are attributable to schools. In line with this, the increase in the positivity rate relates to an age group where the majority cannot yet be vaccinated. “For this reason, repeat testing in addition to the well-known protective measures take on great importance for the population of Switzerland. Targeted measures can be deployed to prevent virus hot spots from forming in schools, from where the virus reaches parents, grandparents and the extended family and circle of friends”, says Daniel Liedtke, CEO of the Hirslanden Group. Testing by means of pooled PRC saliva tests forms an important basis for the monitoring of the Covid-19 virus, which is essential specifically in the current situation. For this reason, the resumption of testing in companies this week also plays an important role – here, too, there is great demand.



With the “TOGETHER WE TEST” platform, the Hirslanden Group offers the possibility of performing repeat tests at schools, health facilities and in companies. Nine cantons are currently working with the solution; just under 5,400 companies are registered at present (before the summer holidays there were 4,600). Some 810,000 tests kits have been ordered since the interruption to testing came to an end on 6 August 2021 – beforehand, orders came to 1.6 million kits in just under four months. In total, 220,836 pool samples have been analysed since the beginning of the project.
