Background Between February and June 2020 , 917 COVID-19 cases and 14 COVID-19-related deaths were reported in Georgia . Early on, Georgia implemented non-pharmaceutical interventions (NPI) including extensive contact tracing and restrictions on movement . Aim To characterize the demographics of those tested and infected with COVID-19 in Georgia; to evaluate factors associated with transmission between cases and their contacts; and to determine how transmission varied due to NPI up to 24 June 2020 . Methods We use data gathered by the Georgian National Center for Disease Control on all polymerase chain reaction tests conducted (among symptomatic patients, through routine testing and contact tracing); hospitalization data for confirmed cases, and contact tracing data . We calculated the number of contacts per index case, the secondary attack rate (% contacts infected), and effective R number (new cases per index case), and used logistic regression to estimate how age, gender, and contact type affected transmission . Results Most contacts and transmission events were between family members . Contacts <40 years were less likely to be infected, while infected individuals> 50 were more likely to die than younger patients . Contact tracing identified 917 index cases with mean 3.1 contacts tested per case, primarily family members . The overall secondary attack rate was 28% (95% confidence interval [CI]: 26-29 %) and effective R number was 0.87 (95% CI 0.81-0.93), peaking at 1.1 (95% CI 0.98-1.2) during the period with strongest restrictions . Conclusion Georgia effectively controlled the COVID-19 epidemic in its early stages, although evidence does not suggest transmission was reduced during the strict lockdown period.
