Methods: We conducted tracing and confirmation among hospital and community contacts. We telephonically interviewed and abstracted information from hospital records and registers. We described the cluster by time, place and person. We conducted unmatched case-control study to compare risk factors and computed Odds Ratio (OR) and 95% confidence interval. Results: We confirmed COVID-19 in 21 of 1478 tested (1.4%). Secondary attack (%) of COVID-19 among 824 contacts was higher among in-patients of block A (18), household contacts (3.4), housekeeping staff (3.3) and nurses (1.7). The cluster started on April 22 with two successive peaks five days apart and lasted until May 8. Being male, patients aged >33 years [OR = 30·7; 95% CI = 3·6 to 264], having hypertension [OR = 4·3; 95% CI = 1·1 to 16·7] or diabetes [OR = 3·8; 95% CI = 1·0 to 14·1] were associated with COVID-19. Mask compliance was poor (20%) among hospital workers. Discussion: We recommended screening of all patients for diabetes and hypertension and isolation/testing of anyone with influenza-like illness for preventing COVID-19 clusters in hospital settings.Suganya BaraniNuzrath JahanMathan KaruppiahSirshendu ChaudhuriMohankumar RajuManickam PonnaiahSwaminathan RajaramanVenktesh VaidhyalingamParasuraman GaneshkumarGirish Kumar CPSendhilkumar MuthappanJegadeesan MurugesanMahalakshmi SrinivasanUsha KrishnanAlby John VargheseElsevierarticleCOVID-19SARS-CoV-2Disease outbreaksHospital clusterPublic aspects of medicineRA1-1270ENClinical Epidemiology and Global Health, Vol 12, Iss , Pp 100889- (2021) |
