Covid lockdown restrictions should not be brought back to help NHS Wales deal with winter pressures, a former health boss has said.
Dr Roland Salmon, former director of communicable diseases for Public Health Wales, said he believed such rules were only “at best marginally” beneficial.
He said efforts should be redoubled to vaccinate those most at risk.
Latest hospital figures show a 20% rise in two weeks of patients with confirmed Covid, while bed occupancy has hit 90%.
Health Minister Eluned Morgan has said further Covid rules before Christmas are “unlikely” at the moment.
