An enhanced testing and tracing system for Covid-19 is to be introduced on Wednesday which is expected to halve the number of cases where health officials cannot identify where a person has been infected. The remaining 20 per cent are classified as cases of community transmission. This frequently reduces the 20 per cent community transmission figure downwards, and the new uniform approach is expected to bring community transmission down to 8-10 per cent. Up to now, contact tracing calls have in most cases only traced activity for the 48-hour period prior to a positive test result. “It’s well within the capacity of the contact tracing system to pick that up,” she said.
