Meeting of the Parliament (Hybrid) 17 March 2021
Our expert advisers on genomics have told us that there is no scientific rationale for mass testing to try to find cases in order to eliminate new variants of concern. If a variant is identified through whole-genome sequencing, local health protection teams carry out enhanced contact tracing. That case is then reported through the four-nations twice-weekly publication on variants of concern. Our approach—which involves extending the circles of investigation and testing for positive cases of a variant of concern—has a clearer scientific rationale than mass testing of entire geographies. Essentially, it is also a quicker way of controlling and containing outbreaks.
