This new science paper suggests  “Appreciable countermeasures have successfully managed the Covid-19 outbreak in Wuhan”. That implies that related countermeasures being enacted worldwide might need an efficient consequence.

This paper has not but been peer-reviewed, however given the velocity (or sluggishness) of that course of, the authors thought they need to do a pre-print first. Typically the net might be the harshest peer-review. – Anthony

We described the epidemiological options of the coronavirus illness 2019 (Covid-19) outbreak, and evaluated the impression of non-pharmaceutical interventions on the epidemic in Wuhan, China.


Particular person-level information on 25,961 laboratory-confirmed Covid-19 circumstances reported by means of February 18, 2020 have been extracted from the municipal Notifiable Illness Report System. Based mostly on key occasions and interventions, we divided the epidemic into 4 intervals: earlier than January 11, January 11-22, January 23 – February 1, and February 2-18. We in contrast epidemiological traits throughout intervals and totally different demographic teams. We developed a susceptible-exposed-infectious-recovered mannequin to check the epidemic and consider the impression of interventions.


The median age of the circumstances was 57 years and 50.three% have been girls. The assault charge peaked within the third interval and considerably declined afterwards throughout geographic areas, intercourse and age teams, besides for youngsters (age <20) whose assault charge continued to extend. Healthcare staff and aged individuals had greater assault charges and severity threat elevated with age. The efficient reproductive quantity dropped from

three.86 (95% credible interval three.74 to three.97) earlier than interventions to zero.32 (zero.28 to zero.37) put up interventions. The interventions have been estimated to stop 94.5% (93.7 to 95.2%) infections until February 18. We discovered that at the least 59% of contaminated circumstances have been unascertained in Wuhan, doubtlessly together with asymptomatic and mild-symptomatic circumstances.


Appreciable countermeasures have successfully managed the Covid-19 outbreak in Wuhan. Particular efforts are wanted to guard weak populations, together with healthcare staff, aged and kids. Estimation of unascertained circumstances has essential implications on persevering with surveillance and intervention
