Somewhat controversially, China has had temporarily relocated those infected with Covid-19 in the Wuhan area to so-called Fangcang hospitals, large communal areas transformed into make-shift hospitals. Although there were up to 13 Fangcang hospitals opened at one point in Wuhan, these were apparently all closed by March 10.
Fangcang shelter hospitals may seem similar to the makeshift and emergency field hospitals used during previous epidemics in other countries, for example, in the USA during the 1918–19 influenza pandemic, or in African countries during the 2014–15 Ebola epidemic. However, they differ in several important ways. First, the Fangcang shelter hospitals in China were established to isolate the patients who were most likely to transmit the infection because they had only mild to moderate COVID-19 and were thus likely to be active in their daily lives and in contact with family and community members. Second, the Fangcang shelter hospitals served an important triage function, separating patients by severity of symptoms, which was not a focus of previous makeshift and emergency field hospitals. [...]
These Fangcang hospitals should not be confused with the other kind of emergency hospitals that China had built earlier, for those more seriously sick with Covid-19, such as the Huoshenshan Hospital. (The latter was a prefab hospital with separate rooms.)
I've heard that some countries are already considering converting open-space structures to some kind of emergency/extra hospitals, e.g. as seen in this US footage. While the open-space conversion resembles more a Fangcang than the other type of prefab Chinese hospital, what do know about plans to mass-quarantine the mild cases in such open-space-conversion hospitals elsewhere, i.e. do (any of) these resemble Fangcangs in (intended) function, not just in looks?
