OSLO, July 28 (Reuters) - Norway postponed for a second time on Wednesday a planned final step in the reopening of its economy from pandemic lockdown, due to the continued spread of the Delta variant of COVID-19, the government said. "A new assessment will be made in mid-August," Health Minister Bent Hoeie told a news conference. Measures that will be kept in place to halt the spread of COVID-19 include bars and restaurants being limited to table service and limits of 20 people on gatherings in private homes. The government in April launched a four-step plan to gradually remove most pandemic restrictions, and had completed the first three of those steps by mid-June. On July 5, Prime Minister Erna Solberg said the fourth step could come in late July or early August at the earliest because of concerns about the Delta coronavirus variant. read more About 80% of adults in Norway have received a first dose of a COVID-19 vaccine and 41% of adults are fully vaccinated, according to the Norwegian Institute of Public Health.
