CoMMinS household study

As well as exploring Covid-19 transmission within schools, CoMMinS study researchers are trying to find out how Covid-19 spreads within households. We are inviting people taking part in the CoMMinS Schools study if they, and their household members and close contacts, are willing to provide saliva samples at home, twice weekly, for four weeks. This is the CoMMinS Household study.

We are inviting people to take part if:

  • They receive a positive PCR test result through participation in the the CoMMinS Schools study, or and
  • A household member of close contact of someone taking part in the Schools study (a pupil or school staff member) has received a confirmed positive test for Covid-19 within the last 5 days.

The study team will then deliver saliva test kits to all of the household members and close contacts who have agreed to take part, to do at home, twice a week for four weeks, and to complete some short questionnaires. The saliva samples are collected by courier, and tested in a University of Bristol research lab for Covid-19 infection.

The CoMMinS saliva test is easy to do, it does not involve swabs or needles, and it is not to do with vaccines.
