Wuhan Coronavirus, also known as 2019 nCoV, has a current death rate of 2-3%. This isn't as high as SARS, but similar to 1918 Spanish influenza. In Wuhan the number of infected is doubling every 6 days. Containment is complicated by the fact that patients can transmit infection before they know they're sick, before any symptoms. Mild infections resemble the flu. Patients can recover from symptoms, feel well, and still be highly contagious. Not all patients have symptoms, and asymptomatic people are potentially contagious. How infectious the dead bodies are is unknown.
Each patient infects 2.2 to 2.5 others. It's about as transmissible as Spanish flu. Ebola infects 2, but it's more lethal. It will not be controlled until each patient infects less than 1 other.
It appears to be out of control in China. Concerns are that countries with "fragile" public health sectors could become secondary sources for global infection. It might become endemic in some areas. The earliest any vaccine might be available is this Summer.
So far the youngest patient to die was 39. It mostly kills older people with health conditions such as high blood pressure or diabetes.
As a vulnerable person by age and health, I consider Wuhan coronavirus a personal threat.
