Estimating and predicting the extent and lethality of the 2019-Novel Coronavirus (2019-nCoV) outbreak, originating in Wuhan/China is obviously challenging, reflected by many controversial statements and reports. Unsurpassed to date, an ever-increasing flow of information, immediately available and accessible online, has allowed the description of this emerging epidemic in real-time [1]. The first patients were reported in Wuhan on December 31st 2019 [2]. Only a few days later, Chinese researchers identified the etiologic agent now known as the 2019-nCoV and published the viral sequence [3]. New data on the virus, its characteristics and epidemiology become available 24/7 and are often shared via informal platforms and media [4]. Yet, key questions remain largely unanswered.
