Covid-19 or SARS-CoV-2 is a virus that is quite similar to usual influenza. It makes some serious pulmonary illness to weak people but that's it. The actual so called pandemic histeria is rather due to a mass psychological effect than a real threat.
In medical terms, rate of death is exactly the same as influenza. Newspaper talk about the worst scenarios only of course. In China the epidemy has already ended. They still have 11 active cases in the whole country today on the 14th of March 2020 (the max amount of infected people is around 81'000).
Still in China official rate of death is 3% among positive tested patients. But you must know that already at the beginning of the virus spreading they had to put restrictions on the tests for two reasons : first it was unnecessary to test patients that didn't require specific treatment and could easily go back home, second they were lacking material. If you add the potential number of patients that never underwent a test, the WHO organisation estimates the rate of death to fall around a number of 0.1 to 0.3%. This number is the exact same one as the seasonal flu (variating from season to season depending on the infectivity). SARS-CoV-2 is recognised to be a highly contagious virus, this is why medical experts expect to have a rate of death closer to 0.3 than 0.1%.
Now to compare with the situations we know in Europe, it is important to recognise we're living the same problem as the Chinese : we lack material to test all the potential patients. This is also why numbers appears to be more deadly than it is in reality. And also we decided a few weeks ago to stop unnecessary testing.
Lots of people talk about the situation in Italy. Epidemiology now shows that 58% of death were among people above 80 years old and 31% of the deceased were in their 70s. We already have 89% of the patients that were in critical condition because of their old age and diminished immunity. Among the 11% left, almost all of them were undergoing treatment for critical medical conditions. And for the small part that's left (around 1%), they were smokers since several years with at least one pack of cigarets per day.
About the children, most of them didn't show any symptoms. They carried the illness and built natural antibodies without being sick. Among all the Chinese exposed children, only 9 were hospitalised and they were suffering leukemia. All of them were cured (and that's quite lucky with such a disease, we must not assume it will happen for any ill child of leukemia or any serious illness).
There were only a few pregnant women infected by the virus in China (let's stay aware that Chinese pregnant women and younger and though healthier women than occidental pregnant women) and all underwent flu symptoms with augmentation of nausea and vomiting only. All of them are alive today and cured. They all underwent specific treatment for the carried child and doctors had to admit later they made more harm to the child than the disease itself as child weren't infected threw placenta.
All the above informations come from multiple sources including the World Health Organisation, the New England Journal of Medicine, the Oxford University Press for the Infectious Diseases Society of America, and some Chinese organisations whose I can't pronounce the name. They're all freely accessible among different international medical databases.
