About this site
How do people transmit coronavirus COVID-19 to each other, and how can they protect themselves from it? These web pages provide summarized, up-to-date information on:
- coronavirus COVID-19 transmission routes in ordinary situations of the general public.
- prevention methods they can use to protect themselves.
It has less on:
- health care services, their high transmission risks, and intensive protections.
- Demographic disparities in which kinds of people have been getting infected or seriously ill.
- Mutating variant coronaviruses.
It does not have information on:
- Medical treatments and vaccines. Other review articles cover those topics well (Mann et al.).
The explanations cite authors’ names in red font, so you can click on those names and look at the linked original research articles, news, and recommendations.
