It’s interesting that its lesser pathogenicity makes it harder to contain.
From New England Journal of Medicine.
“A lack of severe disease manifestations affects our ability to contain the spread of the virus. Identification of chains of transmission and subsequent contact tracing are much more complicated if many infected people remain asymptomatic or mildly symptomatic (assuming that these people are able to transmit the virus). More pathogenic viruses that transmit well between humans can generally be contained effectively through syndromic (fever) surveillance and contact tracing, as exemplified by SARS-CoV and, more recently, Ebola virus. Although containment of the ongoing Ebola virus outbreak in the Democratic Republic of Congo is complicated by violent conflict, all previous outbreaks were contained through identification of cases and tracing of contacts, despite the virus’s efficient person-to-person transmission.”

Yeah, the thing about this virus is, you can be a ‘spreader’ before you even have symptoms - with SARS, only those with symptoms were spreaders.
