Where in Hong Kong are the COVID-19 cases?

Which of the 18 districts is the most dangerous one for getting infected by COVID-19? The risk index is a rough indicator built for this purpose. It is calculated as the number of buildings visited by each confirmed case for each districted divided by the population of that district. The length of visiting, mode of visiting ( residential address? work place? restaurant?) and whether the patient was wearing a mask etc are not considered.

It can be seen as the number of cases normalized by the population and then multiplied by the number of potential sources of infection they were exposed to, or created. Cases reported in the recent weeks are used to show the recent situation.
