Lucky for us the mortality rate is very low, just a bit over two percent and those are people who were ill to begin with.

Yes! We can be thankful for that. And the more serious complications/fatalities seem to be predominantly in the elderly.
If it does take hold here, I'm worried about large urban populations with higher levels of pollution though. Especially for the elderly. I just hear so much about the pollution being a factor in China, so I worry about it being a factor here too.
According to JAMA, on average, people became short of breath within five days of the onset of their symptoms. Severe breathing trouble was observed in about eight days.
The study did not give a timeline for when the deaths occurred.
However, an earlier study published in the Journal of Medical Virology on January 29 said on average, people who died did so within 14 days of the onset of the disease.
The New England Journal of Medicine, in a study published on January 31, also offered a look at how the coronavirus infection affects the body over time.
The study examined medical data of a 35-year-old man, who was the first case of infection in the United States. The first symptom was a dry cough, followed by a fever.
On the third day of illness, he reported nausea and vomiting followed by diarrhoea and abdominal discomfort on the sixth day. By the ninth day, he had developed pneumonia and reported difficulty breathing.
By the twelfth day, his condition had improved and his fever was subsiding. He developed a runny nose, however. And on day 14, he was asymptomatic except for a mild cough. He was still hospitalised at the time the study was published.

The best thing is to keep information up front and current and hold back fear mongering and overreaction.
Just follow the common sense things we've all been taught.
For most patients, COVID-19 begins and ends in their lungs, because like the flu, coronaviruses are respiratory diseases. They spread typically when an infected person coughs or sneezes, spraying droplets that can transmit the virus to anyone in close contact. Coronaviruses also cause flu-like symptoms: Patients might start out with a fever and cough that progresses to pneumonia or worse.
In the early days of an infection, the novel coronavirus rapidly invades human lung cells. Those lung cells come in two classes: ones that make mucus and ones with hair-like batons called cilia.
Frieman explains that SARS loved to infect and kill cilia cells, which then sloughed off and filled patients’ airways with debris and fluids, and he hypothesizes that the same is happening with the novel coronavirus. That’s because the earliest studies on COVID-19 have shown that many patients develop pneumonia in both lungs, accompanied by symptoms like shortness of breath. That’s when phase two and the immune system kicks in. Aroused by the presence of a viral invader, our bodies step up to fight the disease by flooding the lungs with immune cells to clear away the damage and repair the lung tissue.
When working properly, this inflammatory process is tightly regulated and confined only to infected areas. But sometimes your immune system goes haywire and those cells kill anything in their way, including your healthy tissue. “So you get more damage instead of less from the immune response,” Frieman says. Even more debris clogs up the lungs, and pneumonia worsens. (Find out how the novel coronavirus compares to flu, Ebola, and other major outbreaks). During the third phase, lung damage continues to build—which can result in respiratory failure. Even if death doesn’t occur, some patients survive with permanent lung damage. According to the WHO, SARS punched holes in the lungs, giving them “a honeycomb-like appearance”—and these lesions are present in those afflicted by novel coronavirus, too.
On Monday, the Chinese Center for Disease Control and Prevention released clinical details on the first 72,314 patients diagnosed through February 11. The report shows that COVID-19 killed 2.3 percent of patients, meaning it is currently 23 times more fatal than the seasonal flu. Severe disease and deaths were reported in every age group, except kids under nine years old.
