Census Bureau report finds number of Americans working from home tripled in first two years of pandemic
The performance of certain COVID-19 home-testing kits seems to have deteriorated after the omicron variant emerged, according to a new study published Thursday by the British Medical Journal.
The study focused on three widely used rapid antigen tests and found that just one met the World Health Organization’s standard of at least 80% sensitivity, based on its ability to correctly identify a positive sample, and at least 97% specificity, based on its ability to correctly identify a negative sample in patients showing symptoms.
"The researchers found that the sensitivities of the three tests performed with nasal self-sampling decreased during the emergence of omicron, from 87% to 81% for Flowflex, 80% to 73% for MPBio, and 83% to 70% for Clinitest," the BMJ said in a statement.
Performance improved when tests were conducted using both nasal and throat swabs, compared with just nasal swabs. However, only the MPBio test using nasal and throat swabs met the WHO’s standards.
The study involved 6,497 people aged 16 and over at three COVID test sites in the Netherlands between Dec. 21, 2021, and Feb. 20, 2022.
The authors concluded that people with symptoms can rely on a positive rapid antigen test, but those with negative results should adhere to preventive measures because a false negative result cannot be ruled out.
"Given the less than ideal performance of antigen tests, updates to guidance in the public and private sector should take this into account when suggesting action based on test results," said Timothy Feeney, research editor at the BMJ, and Charles Poole of the University of North Carolina in an editorial accompanying the study.
The WHO on Thursday released a response to the recommendations of The Lancet COVID-19 Commission’s report on lessons for the future from the pandemic, saying it generally aligned with the agency’s own commitment to stronger pandemic preparedness.
The commission endorsed the WHO’s central role in global health and agreed it should be supported with an increased budget. It also highlighted how the pandemic exposed challenges such as chronic underfinancing of the UN, rigid intellectual property regimes, a lack of sustainable financing for low- and middle-income countries, and "excessive nationalism," which drove vaccine inequity.

But the WHO pushed back against the report for failing to convey what it called the "full arc" of its response to the crisis from the moment in December of 2019 when it received the first alerts of cases of pneumonia of unknown cause in Wuhan, China.
The WHO has been criticized for moving too slowly in declaring a pandemic and in warning about the human transmissibility of the virus.
The commission also said the WHO was too slow both to support travel bans to prevent the spread of the virus and to endorse the use of face masks in public spaces.
"A comprehensive and detailed list of actions taken by WHO during the COVID-19 response can be viewed in our interactive timeline," the agency said in a statement.
The Lancet commission reserved much of its ire for governments for allowing disinformation to spread across social media, which discouraged many people from getting vaccinated once vaccines were available.
"Too many governments have failed to adhere to basic norms of institutional rationality and transparency, too many people — often influenced by misinformation — have disrespected and protested against basic public health precautions, and the world’s major powers have failed to collaborate to control the pandemic," the authors wrote.
The news comes as U.S. known cases of COVID are continuing to ease and now stand at their lowest level since early May, although the true tally is likely higher given how many people are testing at home, where the data are not being collected.
The daily average for new cases stood at 62,832 on Wednesday, according to a New York Times tracker, down 30% from two weeks ago. The daily average for hospitalizations was down 11% at 33,552, while the daily average for deaths is down 6% to 470.
