I wonder how the 44 students managed to all produce negative PCR tests before flying?
I have a friend that returned from Punta Cana three weeks ago, and the major hotel where he stayed gave him a PCR test certificate without the need to take the test. The hotels don't want to lose tourists, and they don't want to pay for the actual test, so they produce fake reports. Whether this also happens in Mexico, I don't know but ...?
