Zero States Have Decreasing COVID Cases as Delta Variant Spreads

Zero U.S. states have reported a decrease in daily COVID-19 cases over the past week as the Delta variant continues to spread.

According to data from Johns Hopkins University, over the past week, 49 states, as well as Washington, D.C. and Puerto Rico, have seen an increase in daily COVID-19 cases of 5 percent or more.

On Wednesday, the states that saw the highest number of new daily COVID-19 cases were Texas, which reported over 8,100 new cases; California (over 7,700 cases); Louisiana (over 5,300); Missouri (over 2,900); and Georgia (over 2,200).

In addition to those five states, 21 other states reported over 500 new cases on Wednesday, including eight that reported over 1,000 new cases.

The data does not include newly reported cases in Florida and Michigan, but according to a tracker from the Centers for Disease Control and Prevention (CDC), both have seen an increase in new daily cases over the past week. CDC data shows that in Michigan, cases increased by over 1,000 over the past week while Florida saw an additional 20,000 cases when compared to the previous week.

According to the data, Colorado is the only state to see no change in the number of new daily cases reported, but that does not indicate a decrease in daily cases

The data also shows that at least 29 states have seen a 5 percent or greater increase in the daily percentage of positive COVID-19 tests over the past week. According to the data, on Wednesday, over 30 percent of COVID-19 tests in Alabama, Oklahoma and Mississippi came back positive.

The increasing number of cases across all 50 states comes as health officials have continued to warn of the dangers surrounding the COVID-19 Delta variant, or B.1.617.2.

The Delta variant was first reported in India but has now spread across the globe, and according to the U.S. Centers for Disease Control and Prevention (CDC), the variant has increased transmissibility.

During a recent congressional hearing, CDC Director Dr. Rochelle Walensky said that the Delta variant now accounts for at least 83 percent of COVID-19 cases in the U.S. Walensky noted that the new percentage is a "dramatic increase" from a previous estimate that found the Delta variant accounting for at least 50 percent of cases in the nation.

While speaking at the congressional hearing, Walensky said that increasing COVID-19 vaccinations are the key to curbing the transmission of the Delta variant.

"The best way to prevent the spread of COVID-19 variants is to prevent the spread of disease. And vaccination is the most powerful tool we have," she said. "We must continue to expand vaccine coverage by building trust and confidence in COVID-19 vaccines. And this is particularly important in communities of color, rural communities, and other population groups at risk."

Dr. Anthony Fauci, chief medical adviser for the White House, also spoke during the congressional hearing and said, "The reason it's so formidable is the fact that it has the capability of transmitting efficiently from human to human in an extraordinary manner, well beyond any of the other variants that we've experienced, up to now."

As the Delta variant has continued to spread, some areas across the U.S. have decided to reimpose mask mandates, including Los Angeles County in California.

Newsweek reached out to the CDC for comment but did not receive a response in time for publication.
