A new study out of the U.K. found Covid-19 antibodies provide some immunity against the virus for at least five months. The study, which surveyed thousands of British health care workers, was conducted before new, highly transmissible variants of the virus were detected in the U.K., South Africa and most recently the United States. Still, it helps fill in a key detail on the scientific timeline of infection, recovery and immunity that could prove critical in containing the virus. The study has not yet been peer-reviewed, and its authors caution the conclusions are preliminary analysis.
The U.S. is recording at least 245,300 new Covid-19 cases and at least 3,360 virus-related deaths each day, based on a seven-day average calculated by CNBC using Johns Hopkins University data.
The following data was compiled by Johns Hopkins University:
- Global cases: More than 92.77 million
- Global deaths: At least 1.98 million
- U.S. cases: More than 23.21 million
- U.S. deaths: At least 386,996
