The number of Americans who have tested positive for the coronivirus is up almost 40 percent since April, the CDC reported Wednesday.
The increase is part of a broader trend: As the pandemic has grown, so have the number of people who have been tested.
The rise in positive tests follows a dramatic decline in infections across the United States, which began in the summer of 2013.
But the CDC said Wednesday that the numbers of people tested are up just as quickly as they were in June, before the coronovirus outbreak became widespread.
The total number of confirmed cases of the coronaveis has fallen from 9,839 to 8,868 in the past month.
The number of new cases is up by more than 4,000 from the same month in 2014, the last month before the pandemics began.
The overall number of cases has remained steady at a healthy level, with about 1,500 new cases per day.
But the new numbers show a worrisome rise in new cases in the months since the coronaves started, with a recent spike in the first two weeks of July, the highest since May.
The CDC also said that the number that has been diagnosed with COVID-19 in the U.S. has more than doubled since the beginning of July.
The agency said the number diagnosed with the virus in June was 1,903, but the number on Wednesday was up to 1,954.
In addition to the rise in cases, the agency said that more people are dying of COVID infection as a result of the pandems, which has led to a rise in the coronvirus death toll.
The coronaviruses spread rapidly through the air and on the ground, and there is no vaccine to prevent them.
There are about 9 million coronaviral infections in the world, most of them in the United Nations’ poorest nations.
