The report said that in the regular monitoring of the new coronal virus variant, they found that B.1.517 mutant strains appeared in Connecticut, and this variant had disappeared around the world for a long time. Through tracking, the research team found a 60 -year -old lymphoma patient. The patient first detected the positive of the new coronary virus in November 2020, and the test results of the test in March 2022 were positive.

"Within 471 days after the first diagnosis, the patient's new crown test results have been positive." The report added that the patient was contagious and basically had high virus load during this time. In addition to long -term infection, this research team also noticed that over time, the new crown virus rapidly mutated in the patient's body, and even three different new variants appeared. The report states that the variation speed of the new coronal virus in this patient may be twice the speed of mutation in ordinary people.
