Abstract

Bangladesh reported the first three laboratory-confirmed COVID-19 cases on March 8, 2020 in Dhaka and Narayanganj cities. As of April 8, 2020, 218 confirmed cases across the country, they have mostly detected from Dhaka (56.4%) and Narayanganj (21%) cities where the hotspots of an outbreak of COVID-19 disease. There were 6 cases in Dhaka district excluding metropolitan areas and rest of 43 (20%) cases in the 19 other regions. Local government-enforced completely shut down the hotspots areas on April 8 2020. However, peoples from hotspots travelled openly to the other districts.

We aimed to understand the risk of open movement from hotspots. We studied 40 individuals who were infected with SARS-CoV-2 virus later at their destination. We developed a route map and density maps using Geographic Information System (GIS). Among the studied people, the average distance was 140.1 (75.1) kilometers (Km), and the range of distance was from 20.3 to 321.7 kilometers. Among them, 42.5% traveled <100 Km, 40.0% traveled between 100 and 200 Km and 17.5% traveled above 200 Km. Case numbers were increased 13.5 times more on April 20 than the cases as of April 8, 2020.

Our analysis suggests that relaxed travel restriction could play an important role to spread COVID-19 transmission domestically. To reduce further spread of COVID-19, the government should closely monitor the public health intervention to stop the casual movement.
