Friday, April 23, 2021 (HealthDay News)-Isolated NBA players who have recovered from COVID-19 but still tested positive for the virus have left without infecting others isolationA new study found.

Researchers say that there has always been a constant fear that people with COVID will infect others, but these findings from the Professional Basketball League show that many recovered people can reconnect with others without spreading the virus.

Christina Mack, principal investigator of IQVIA, Real World Solutions in Durham, North Carolina, said: “Re-infection of COVID-19 is possible, especially now that there are new variants, and every one should be taken seriously. A positive test.”

However, this 2020 study shows that after people recover from COVID, sensitive tests such as RT-PCR may continue to produce positive results. Mike said that these people are not contagious in the NBA campus environment.

In order to complete the 2019-20 season, the NBA has established a “bubble zone” in Orlando, Florida, which is a closed campus and is governed by scientific regulations to prevent COVID-19.

More than 3,500 people live on the campus and are bound by its regulations. All of them underwent daily RT-PCR testing. Some have recovered from previous COVID infections.

Mike said: “These survivors did not get sick and were not observed to be contagious to others, but instead excrete the virus particles at the low levels left by the previous infection.”

She said: “We have observed that individuals can test positive within 118 days after the start of the infection, and many of these individuals test negative for most of the time before and after their positive test.”

Among the participants, 1% had a persistent virus, and most were under 30 years old and male. In these persistent cases, antibodies were found in 92%, and all were asymptomatic. Researchers reported that these people were monitored and no virus was spread to other people.

Dr. Robert Gratt, an emergency physician at Lenox Hill Hospital in New York, was not part of the study, but reviewed the results of the study.

“The findings support the premise that asymptomatic people are satisfied [U.S. Centers for Disease Control and Prevention] The standard to terminate the separation, but its RT-PCR test results continue to be positive, and it seems that it is not infectious to other people. “
