How Many People Have Coronavirus?

The interactive map below highlights the total numbers of confirmed cases from each country affected.

How Did It Start?

China’s National Health Commission originally traced exposure to a seafood market in Wuhan, but later reports indicate that the market was unlikely to be the only source of the virus.By January 7, the exact strain—a new type of coronavirus—was identified, and initially named 2019-nCoV.

In February, the World Health Organization officially began calling the disease COVID-19.

First Deaths

A 61-year-old Chinese man was the first known person to die from coronavirus-related illness; he was admitted to the hospital with pneumonia and acute respiratory distress syndrome.

Media beganreporting his deathon January 10, 2020, adding he was a regular customer at the Wuhan seafood market. By January 31, there were 213 deaths and 9,720 confirmed cases of COVID-19 in China.

First Spread Outside of China

Thailandreported its first case of COVID-19 on January 13, 2020. The infected individual had traveled there from Wuhan.

Japanreported its first case on January 15, also in a person who had visited Wuhan.

Spread to the United States

On January 21, 2020, Washington State reported the first case of the new coronavirus in the United States in a man who had returned from Wuhan, China.

Person-to-Person Spread

The first instance of a person transmitting COVID-19 to another person while in the United States was reported in Chicago, Illinois, on January 30.A woman in her 60s contracted the virus while caring for her father in China, passing it to her husband when she returned home.

Community Spread

The early cases of COVID-19 in the U.S. were limited to people who had traveled from China and those they interacted closely with. But on February 26, the CDC confirmed a case in California with no reported travel connection to China or exposure to another person with COVID-19.

This marked the first possible instance of community spread—the spread of an illness with an unknown source of infection.

U.S. Takes Global Lead In COVID-19 CasesBy March 26, the U.S. had more confirmed global COVID-19 cases than any other country. As of December 22, 2020, the CDC reported 17,790,376 cases—both confirmed and presumptive. See the full breakdown of reported cases across the country below.

U.S. Takes Global Lead In COVID-19 Cases

By March 26, the U.S. had more confirmed global COVID-19 cases than any other country. As of December 22, 2020, the CDC reported 17,790,376 cases—both confirmed and presumptive. See the full breakdown of reported cases across the country below.

Deaths

On February 29, the CDC announced a 54-year-old man from Washington State was the first person in the U.S. to die of COVID-19-related illness.According toHarborview Medical Center in Seattle, where he was treated, the man had underlying medical conditions.

February 6 is anew dateconsidered to possibly mark the earliest COVID-19-related death in the U.S. This comes after medical examiners in Santa Clara County, California, examined cases they were suspicious about but did not have the tests for at the time.

Officials say the victim was a 57-year-old woman who likely contracted the virus from community spread, meaning COVID-19 has been present in the U.S. for longer than previously thought.

Since then, 316,844 total deaths have occurred in the U.S.

WHO Declares Global Health Emergency

In a January 31 situation report listing 9,826 confirmed cases globally, the World Health Organization declared COVID-19 “a public health emergency of international concern.” At this time, 19 countries outside of China were affected.

On March 11, after confirming over 118,000 cases in 114 countries, WHO elevated the status to a pandemic.

Proposal to Reopen US Economy

The guidelines propose specific criteria to be met before the three-phase approach begins:

Phase One:

Phase Two:

Phase Three:

As of May 1,states have reopenedparts of their economy and public life. What that means for each state is different; for some, only certain retailers or places of worship are open, while others, like Georgia and Texas, are embracing a return to restaurants, retail, outdoor recreation, gyms, salons, and entertainment.

Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, has warned against re-opening too much too soon, and predicts more COVID-19 outbreaks in light of rolling back physical distancing protocols.
