I have a PhD in immunology. My grad school friends and professors from our microbiology and immunology department are taking this seriously. I work as a science and medical editor and have read some of the clinical literature. Just because the death rate is not as high as those associated with some other diseases, don't kid yourself that this isn't serious. Left unchecked, it will overwhelm medical facilities and resources quickly, as it did in Hubei Province, China and is currently doing in Italy, Iran, Spain, Washington State, USA, and other places.
This is a highly contagious pathogen to which no one has natural immunity and 15-20% of detected cases are sick enough to require medical treatment. In the most severe cases (roughly 5%), that's mechanical ventilation under isolation conditions for weeks. If the last SARS is any indication, some people will have permanent lung damage.
Believe what you want, but don't impose your beliefs on others by putting them at risk. Social restrictions haven't been imposed without a lot of forethought.
