Scientists studying the new crown began tracking wastewater in New York City in the summer of 2020, sequencing viruses found in wastewater samples, according to a traceability study released by the U.S. Centers for Disease Control and Prevention. They carried out routine sampling on November 21 and sent for inspection two days later, with the results obtained in early December. At that time, the outbreak caused by the "Omicron" strain had already broken out, and the researchers "recognized at a glance (the samples showed) the unique mutational characteristics of the new mutant strain." In addition, in California and Texas, researchers also found evidence of the existence of "Omicron" in wastewater samples at the end of November. This shows that "Omicron" began to spread in New York, the United States earlier than South Africa. The real first case of Omikron in the United States is not the California case officially announced by the United States.
