Authoritative information on the virus can be found on these sites, from Library Journal:
Centers for Disease Control and Prevention (CDC)
The CDC, the main U.S. federal agency monitoring and responding to the novel coronavirus outbreak, has created a microsite with frequently updated information for health practitioners, researchers, and the general public. Of particular interest to the public is the Situation Summary, a quick overview with maps of reported coronavirus cases in the United States and globally.
Intended for the general public, this health encyclopedia and information portal produced by the U.S. National Library of Medicine provides background on coronaviruses, along with updated information and links concerning the 2019 novel coronavirus. Users can also search MedlinePlus for links to high-quality health and medical information from other government agencies and trusted third-party organizations.
World Health Organization (WHO)
The WHO, a leading international health agency helping to coordinate the global response to the coronavirus outbreak, offers global news updates and helpful videos, answers common questions (Should I wear a mask to protect myself? How does this virus spread?), and dispels myths (no, gargling with mouthwash won’t protect against the virus).
