It is very contagious: there is no doubt about that. The new coronavirus has infected more than 90,000 people in at least 73 countries in a few months since it was discovered in the central Chinese city of Wuhan. And now that it is spreading locally in the United States we all want to know exactly how it is transmitted. There is a general answer to this question, but because it is a new virus that is being studied, there is still no information that one would like and that other viruses such as influenza are available.
However, these guidelines can help you take precautions.
