From two weeks prior to hospitalization, meeting people other than your family members as well as going out unless it is absolutely necessary, are forbidden.
ご質問ありがとうございます。
"From two weeks prior to hospitalization"＝「入院する2週間前からは」
"meeting people other than your family members"＝「家族以外の人達と会うこと」
"as well as going out unless it is absolutely necessary,"＝「そして絶対必要な場合以外に外出すること」
"are forbidden."＝「は禁じられています。」
ご参考に。
