The group attributed some of the drop in testing to technical issues with reporting systems as well as storm-related closures in some states.

\"Still, the problem is broader. Weekly testing declined for the first time ever in our dataset,\" the COVID Tracking Project wrote in a series of posts on Twitter. \"There are widespread problems right now in the top-level data. In different ways, California and Florida have had trouble reporting complete data because of storms and IT problems. Because they are populous states with large outbreaks, that influences the national numbers.\"

Since the start of the pandemic, a total of 85 children under the age of 2 had tested positive for the virus in Nueces County by mid-July. Now, that number is \"close to 167,\" according to Annette Rodriguez, health director of the Corpus Christi Nueces County Public Health District.

\"That number has almost doubled and that hasn't been a very long time period,\" Rodriguez told KIII.

5:28 a.m.: Data shows disproportionate number of non-white children are dying in US

A disproportionate number of non-white children are dying from the novel coronavirus in the United States, according to data released in an internal memo from the Federal Emergency Management Agency obtained by ABC News on Wednesday night.

Nationwide, the number of COVID-19 cases among people under the age of 18 from March 1 to Aug. 3 were 40% Hispanic, 34% white and 19% Black. The ethnicity breakdown of those patients who died from the disease is 38% Hispanic, 34% Black and 25% white, according to the memo.

The gender breakdown of those cases is 50% male and 50% female. However, just as in adults, COVID-19 is more fatal among males under 18, making up 64% of the deaths compared to females under 18 accounting for 36%, according to the memo.

What to know about coronavirus:

3:39 a.m.: US records over 52,000 new cases in a single day

More than 52,000 new cases of COVID-19 were identified in the United States on Wednesday, according to a count kept by Johns Hopkins University.

It's the second straight day that the nation has recorded over 50,000 new cases. Wednesday's caseload, however, is still below the record set on July 16, when more than 77,000 new cases were identified in a 24-hour reporting period.

A total of 4,823,892 people in the U.S. have been diagnosed with COVID-19 since the pandemic began, and at least 158,256 of them have died, according to Johns Hopkins. The cases include people from all 50 U.S. states, Washington, D.C., and other U.S. territories as well as repatriated citizens.

By May 20, all U.S. states had begun lifting stay-at-home orders and other restrictions put in place to curb the spread of the novel coronavirus. The day-to-day increase in the country's cases then hovered around 20,000 for a couple of weeks before shooting back up and crossing 70,000 for the first time in mid-July.

Many states have seen a rise in infections in recent weeks, with some -- including Arizona, California and Florida -- reporting daily records.

New data suggests that the national surge in cases could be leveling off, according to an internal memo from the Federal Emergency Management Agency obtained by ABC News on Tuesday night. Nationwide, the last week saw a 9.2% decrease in cases from the previous seven-day period. There was also a 7% increase in new deaths compared to the previous week, but the figure is lower than the 20-30% week-over-week increase the country has seen of late, according to the memo.

ABC News' Stephanie Ebbs, Kendall Karson, Josh Margolin, Arielle Mitropoulos, Cindy Smith, Eric Strauss and Scott Withers contributed to this report.
