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

ABSTRACT

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.
