Logan Bik and Sloane Bozzi

As some countries begin to see a decrease in the number of COVID-19 cases, the United States continues to see an uptick of positive COVID-19 cases.

With the U.S. having more confirmed cases of COVID-19 than any other country, data shows that the U.S. is expected to see a rise in case numbers in the near future. On the west coast, Los Angeles has been a hotspot for the virus.

We have compiled data from the Los Angeles County Department of Public Health and the Johns Hopkins University and Medicine’s Coronavirus Resource Center to show a breakdown of Angelenos affected by COVID-19. Data is up to date as of July 5, 2020.

Race and Ethnicity Testing:

60% of those being tested are of unknown ethnicity or race, so it is difficult to say if all ethnicities and races are being tested adequately.
