Countries facing a resurgence of coronavirus cases after reopening have reverted back to lockdowns, with many focusing on isolating specific regions with spiking rates of infections.

But the willingness to retighten restrictions amid growing public health concerns stands in stark contrast to the U.S.' approach to a fresh wave of new cases.

Despite skyrocketing numbers of new cases in states like Texas, Arizona and Florida, state officials are reluctant to shutter stores, businesses, and enforce stay-at-home mandates.

Texas officials announced over 5,000 new infections on Tuesday -- a single-day record for the state -- while a children's hospital began admitting adult patients to accommodate a surge of cases near Houston.

Gov. Greg Abbott warned residents to take the necessary precautions, such as wearing a mask and practicing social distancing, before venturing outside.

In Arizona, hospitals reported 84 percent of intensive care unit beds and 83 percent of inpatient beds were in use as of Monday, according to the data from the state's Department of Health Services, and a record high of 3,591 new cases were reported on Tuesday.

Trump has publicly said he has instructed officials to "slow down" testing in an effort to reduce the number of newly recorded coronavirus cases. Administration officials later said he made those comments "in jest" though Trump told reporters afterward he wasn't joking.

Health officials told Congress on Tuesday that they will continue to test rigorously for the virus to isolate its spread and that no one has told them to do otherwise.

After weeks of trending downwards, new coronavirus cases in the U.S. have surged to their highest level in two months and are now back to where they were at the peak of the outbreak, the Associated Press reported.

Meanwhile, officials around the world are relying on increased testing to paint a more accurate picture of coronavirus resurgence in regions where the virus is rearing its head after businesses were allowed to reopen.

In Germany, more than 1,550 people tested positive for COVID-19 at the Toennies slaughterhouse in Rheda-Wiedenbrueck, forcing two counties to reimpose closures of movie theaters, gyms, and other businesses, while schools and daycare centers remain closed and public social interactions are limited to two people from the same family.
