Hong Kong has so far appeared to keep the coronavirus outbreak largely under control, with a total of 129 confirmed cases reported as of Mar. 11, of which 39 were imported. Schools have been closed since late January, many companies have transitioned to working from home, and the overwhelming majority of people on streets wear masks. Hong Kongers appear to have done so well with their social distancing and personal hygiene measures, in fact, that there has been a sharp drop in flu cases compared to previous years, according to data from health officials. Still, many are dissatisfied with what they see as late and piecemeal responses from the government, especially its delay in restricting arrivals from mainland China.

While latest passenger numbers for the month of February are not yet available, anecdotal evidence suggests there has been a sharp drop in ridership since Covid-19 began taking hold in the city of 7.4 million. The MTR has also been battered by months of large-scale protests starting last June. Stations and trains have been vandalized, causing an estimated $204 million in damages. In its annual report released earlier this month, MTR specifically noted (pdf) the “ongoing local public order events in Hong Kong and the Covid-19 outbreak” as challenges and sources of uncertainty going forward.

Other metro stations around the world have stepped up cleaning measures, too. The MTA in New York City announced this week that it would double its daily cleaning to two comprehensive wipe-downs of surfaces each day, while the Boston subway system is sanitizing its station surfaces every four hours. Singapore’s subway is doing the same, with surfaces disinfected three times a day.
