Of the 18 cases recorded in the 24 hours to 8 p.m. Monday night, 11 were in complete isolation during their infectious period and a further five were in partial isolation during their infectious period. "Some cases (that) have been received are quite historic, so people have been exposed in the community for a number of days and that is not what we want to see," said NSW Premier Gladys Berejiklian.
