Contact tracing failing in some cases due to 'incorrect phone numbers' - HSE

The HSE has said that the reason contact tracing has not been immediately initiated on all persons testing positive for Covid-19 is due to the fact that the phone numbers of those being tested “may be incorrect”.
A trend has emerged in recent weeks of general practitioners receiving the positive result of a patient and informing them of that fact, only to discover the person was previously unaware of their positive status.
