不同家庭新型冠状病毒肺炎临床影像学及防控对策分析

Analysis of clinical imaging and prevention and control strategy of COVID-19 pneumonia in different families

目的 提高对家庭聚集性新型冠状病毒肺炎的临床和影像改变的认识,探索具有针对性的疫情防控策略。方法 回顾性分析10组新型冠状病毒肺炎家庭共27例病例的临床症状及影像学检查资料。结果 27例病例中,男12例,女15例,年龄6个月至57岁,轻型12例,普通型15例。所有患者中5例表现为发热,20例表现为咳嗽咳痰,13例表现为鼻塞流涕,5例表现为咽干咽痛,5例表现为嗅觉味觉丧失,2例表现为头晕头痛。15例普通型患者中,病变累及双肺10例,累及单侧肺5例,累及下叶8例,胸膜下9例;表现为磨玻璃影9例,高密度影7例,胸膜增厚3例;未见胸腔积液、纵隔及腋窝淋巴结肿大征象。结论 家庭聚集性新型冠状病毒肺炎临床及影像学具有一定的特点,重视发热门诊的哨点监测作用,积极控制传染源、采取非药物干预联合强化疫苗接种是打赢疫情防控攻坚战重要策略。

Objective To increase the understanding of the clinical and imaging changes of family clustered novel coronavirus pneumonia, and to explore the targeted epidemic prevention and control strategies.Methods The clinical symptoms and imaging examination data of 27 cases in 10 groups of new coronavirus pneumonia families were retrospectively analyzed.Results Among the 27 cases, 12 males and 15 females, aged 6 months old-57 years old, 12 cases were the mild type and 15 cases were the common type.Among all cases, 5 cases were manifested by fever, 20 cases by cough and expectoration, 13 cases by nasal congestion and runny nose, 5 cases by dry throat and sore throat, 5 cases by loss of smell and taste and 2 cases by dizziness and headache.Among the 15 cases of common type, 10 cases involved both lungs;5 cases involved unilateral lung;8 cases involved the lower lobe, and 9 cases involved subpleural;9 cases showed the ground-glass opacity;7 cases showed the high density film;there were 3 cases of pleural thickening;no pleural effusion, mediastinal and axillary lymph node enlargement signs were observed.Conclusion The family clusters of novel coronavirus pneumonia have certain clinical and imaging characteristics.Attaching the importance to sentinel surveillance in fever clinics, actively controlling the source of infection, and adopting the non-drug intervention combined with intensive vaccination are the important strategies to win the battle against the epidemic.
