Sorry, I misread the report. 20% of those who get the viral pneumonia are dying while the overall death rate is 3% of those who test positive for nCoV.

Below is something interesting from Foreign Policy magazine:

"Yet few children have yet been reported with coronavirus symptoms. That does not mean that no children have been infected. A similar pattern of benign disease in children, with increasing severity and mortality with age, was seen in SARS and MERS. SARS had a mortality rate averaging 10 percent. Yet no children, and just 1 percent of youths under 24, died, while those older than 50 had a 65 percent risk of dying. Is being an adult a risk factor per se? If so, what is it about childhood that confers protection? It may be the nonspecific effects of live vaccines such as for measles and rubella, which already have been found to provide protection from diseases beyond their immediate target. That may also explain why more men than women have been infected by the coronavirus, because women routinely are given a rubella vaccine booster in their teens to guard against the dangers of having rubella while pregnant. While we wait for an accelerated coronavirus vaccine to be ready, could innate immunity in adults be boosted by giving measles vaccines?"

Frequent travelers to China might consider getting a measles booster before they travel.
