This spike comes despite warnings from health officials.

If anyone is traveling, the Centers for Disease Control and Prevention say they should get a COVID-19 test one to three days before the trip. They should also be tested again three to five days after the trip and self-quarantine for seven days, even if the test comes back negative.

Airlines have been concerned the CDC might mandate a negative COVID-19 test before any travel, but the agency says it is not considering that at this time.
