Information about the novel coronavirus (the virus that causes COVID-19) is constantly evolving. We will refresh our novel coronavirus content periodically based on newly published peer-reviewed findings to which we have access. For the most reliable and up-to-date information, please visit the CDC website or the WHO’s advice for the public.
Since the COVID vaccines have become so widely available, the distribution of infections is changing. Johns Hopkins University has established a website where you can see the number of people who have become infected, the number of deaths from COVID-19, and the number of vaccines that have been distributed world-wide.

How to interpret coronavirus data
Researchers at the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University have developed a web-based dashboard based on various data sources. The dashboard reports cases down to the province level in China, the city level in the US, Canada, and Australia, and the country level for all other areas.
The primary data source for the Johns Hopkins map is an online platform called DXY. DXY is an online community of doctors and other healthcare providers and institutions that collects reports from local media and government at the province level to estimate totals of COVID-19 cases close to real-time. Researchers also add cases manually by monitoring various Twitter feeds, online news services, and direct communications sent through DXY. Case numbers are confirmed through various health departments, including the China CDC, World Health Organization (WHO), and European CDC.
For city-level reports of COVID-19 cases in the US, Canada, and Australia, the researchers used data from the US CDC and the Canadian and Australian governments, plus various state or territory health authorities.
Reading the dashboard
In the upper right-hand corner, the number of “total recovered” vs. “total deaths” is reported. Keep in mind that these numbers may not be completely reliable because of questions about testing and because people with mild symptoms may not be getting tested. However, these maps represent some of the most recent data we currently have and are subject to change quickly.
