病例密切接觸者的居家醫(yī)學(xué)觀察指南

    新型冠狀病毒感染的肺炎確診病例的密切接觸者應(yīng)從和病人接觸的最后一天起采取醫(yī)學(xué)觀察14天。在家中觀察期間需與醫(yī)學(xué)觀察人員保持聯(lián)系，并需要了解病情觀察和護(hù)理要點(diǎn)，掌握家庭預(yù)防的洗手、通風(fēng)、防護(hù)和消毒措施。

    在居家醫(yī)學(xué)觀察期間的具體建議如下：

    （一）將密切接觸者安置在通風(fēng)良好的單人房間，拒絕一切探訪。

    （二）限制密切接觸者活動(dòng)，最小化密切接觸者和家庭成員活動(dòng)共享區(qū)域。確保共享區(qū)域（廚房、浴室等）通風(fēng)良好（保持窗戶開(kāi)啟）。

    （三）家庭成員應(yīng)住在不同房間，如條件不允許，和密切接觸者至少保持1米距離。哺乳期母親可繼續(xù)母乳喂養(yǎng)嬰兒。

    （四）其他家庭成員進(jìn)入密切接觸者居住空間時(shí)應(yīng)佩戴口罩，口罩需緊貼面部，在居住空間中不要觸碰和調(diào)整口罩?？谡忠蚍置谖镒儩?、變臟，必須立即更換。摘下并丟棄口罩之后，進(jìn)行雙手清洗。

    （五）與密切接觸者有任何直接接觸，或離開(kāi)密接接觸者居住空間后，需清潔雙手。準(zhǔn)備食物、飯前便后也均應(yīng)清潔雙手。如果雙手不是很臟，可用酒精免洗液清潔。如雙手比較臟，則使用肥皂和清水清洗。（注意酒精使用安全，如意外吞食用或引發(fā)火災(zāi)）。
