RESUMEN
OBJECTIVES: To determine the prevalence of SARS-CoV-2 detection among international travellers to Ghana during mandatory quarantine. DESIGN: A retrospective cross-sectional study. SETTING: Air travellers to Ghana on 21st and 22nd March 2020. PARTICIPANTS: On 21st and 22nd March 2020, a total of 1,030 returning international travellers were mandatorily quarantined in 15 different hotels in Accra and tested for SARS-CoV-2. All of these persons were included in the study. MAIN OUTCOME MEASURE: Positivity for SARS-CoV-2 by polymerase chain reaction. RESULTS: The initial testing at the beginning of quarantine found 79 (7.7%) individuals to be positive for SARS-CoV-2. In the exit screening after 12 to 13 days of quarantine, it was discovered that 26 of those who tested negative for SARS-CoV-2 in the initial screening subsequently tested positive. CONCLUSIONS: Ghana likely averted an early community spread of COVID-19 through the proactive approach to quarantine international travellers during the early phase of the pandemic. FUNDING: None.
