The US Food and Drug Administration has alerted health care providers and labs that genetic variants of the novel coronavirus — including an emerging variant first detected in the United Kingdom called B.1.1.7 — could lead to false negative Covid-19 test results.

The US Food and Drug Administration has alerted health care providers and labs that genetic variants of the novel coronavirus — including an emerging variant first detected in the United Kingdom called B. 1. 1. 7 — could lead to false negative Covid-19 test results.

The agency notes three Covid-19 tests authorized in the United States may be impacted by genetic variants — MesaBiotech Accula, TaqPath Covid-19 Combo Kit and Linea Covid-19 Assay Kit — "but the impact does not appear to be significant. ”

That “may help with early identification of new variants in patients to reduce further spread of infection,” the FDA said in its letter to labs and health care providers, noting that the B. 1. 1. 7 variant has been associated with an increased risk of transmission

"The FDA will continue to monitor SARS-CoV-2 genetic viral variants to ensure authorized tests continue to provide accurate results for patients," FDA Commissioner Dr. Stephen Hahn said in the release.

The US may have its own version of a more transmissible coronavirus that might be helping fuel the already aggressive spread of the virus, the White House coronavirus task force said in its latest report to states this week.

Significant continued deterioration, from California across the Sunbelt and up into the Southeast, Mid-Atlantic, and Northeast, despite low testing rates during the holidays, suggests aggressive community spread,” the task force reports said.

No vaccines should be in freezers but should instead be put in arms now; active and aggressive immunization in the face of this surge would save lives,” the reports said.

A worrying fungal infection seen among hospitalized Covid-19 patients in Florida may have been caused by the reuse of personal protective equipment, Centers for Disease Control and Prevention researchers said Friday.

Outbreaks of Covid-19 cases in nursing homes reflect what’s going on in the community, and protecting frail residents means watching what’s going on outside, according to new research from the Centers for Disease Control and Prevention published Friday.

The study is based on data about Covid-19 cases in nursing home residents and staff members in all 50 states, collected from May 2020 to November 2020.

Out of the total cases of Covid-19 in nursing homes reported, just more than half were in residents, while just less than half were in staff members.

Georgia has administered 24. 88% of the Covid-19 vaccine it has received from the federal government, but the state's governor said he feels that the data on vaccinations by providers is being under reported to the state.

"Beginning soon Georgians over 65 and those other priority populations can visit the Georgia Department of Public Health's website to find locations in your community where you can schedule an appointment for the vaccine,” Kemp said.

“We are going to use every single resource that we have in the state to get this vaccine in people's arms,” he said, adding, “Vaccines don’t save lives, vaccinations do. ”  

The second dose of Pfizer and BioNTech’s coronavirus vaccine can be delayed for as long as six weeks if need be, World Health Organization advisers said Friday.
