The recommendation coincides with a new report finding asymptomatic bird flu infection in some workers. Those cases were discovered using blood, or serology, testing and seem to have been transmitted from sick animals, not people. To date, 46 people have been diagnosed with bird flu, also known as H5N1, in the United States this year. Of those 115, eight (7%) had antibodies showing they’d been infected with the bird flu. Until now, workers who had a known exposure to bird flu but didn’t have symptoms haven’t been routinely tested.

☆ As bird flu outbreak expands in California, dairy farms report it’s worse than they expected

CNN —A third farmworker has tested positive for bird flu in California, according to the state’s health department. Like the first two human cases in California, this third case is a farmworker who was in contact with sick dairy cattle. The CDC’s Principal Deputy Director, Dr. Nirav Shah, said in a news briefing on Friday that these cases were not a surprise. The California Department of Food and Agriculture has been conducting bulk milk tank sampling in areas where herds test positive. The first infected herds in California were found in late August.

Even as it has become increasingly clear that the bird flu outbreak on the nation’s dairy farms began months earlier — and is probably much more widespread — than previously thought, federal authorities have emphasized that the virus poses little risk to humans. Yet there is a group of people who are at high risk for infection: the estimated 100,000 men and women who work on those farms. That leaves the workers and their families vulnerable to a poorly tracked pathogen. And it poses broader public health risks. If the virus were to find its way into the wider population, experts say, dairy workers would be a likely route.

☆ Opinion: The next pandemic threat demands action now

Well, so far US officials are saying they believe there is minimal risk to the public from the latest iteration of bird flu. According to the Global Health Security Index, there are significant gaps in countries’ pandemic preparedness capabilities. Given the impact of Covid, it is deeply disappointing that national governments are not investing the necessary resources to build life-saving pandemic preparedness capacity. Making matters worse, Congress has made major cuts to pandemic preparedness funding, as part of the ongoing appropriations process. Playing the long game also means supporting the World Bank Pandemic Fund, which is designed to invest in long-term pandemic preparedness capacity of low- and middle-income countries.

☆ Some states are loosening their Covid isolation guidelines, shifting away from CDC recommendations

Oregon changed its isolation policy in May when the Covid-19 public health emergency lifted, and California followed suit earlier this month. The recent order from the California health department notes that the potential infectious period spans from two days before through 10 days after symptoms or a positive test. Less restrictive isolation policies could allow people to feel more comfortable with testing, which could prompt them to get treatment or feel more comfortable taking other protective measures. Dr. Dean Sidelinger, Oregon’s state health officer, said that equity was a key factor considered in the decision to change isolation policy in the state. Public health policy decisions are rarely black-and-white, experts say, and weighing tradeoffs can be more of an art than a perfect science.

☆ U.S. records 100 million Covid cases, but more than 200 million Americans have probably had it
▼ + stars: | 2022-12-28 | by ( Spencer Kimball | ) www.cnbc.com time to read: +7 min

The U.S. officially recorded more than 100 million cases as of Tuesday, just under one-third of the total population, according to data from the Centers for Disease Control and Prevention. Covid-19 has easily infected more than 200 million in the U.S. alone since the beginning of the pandemic — some people more than once. "There are have been at least 200 million infections in the U.S., so this is a small portion of them," Frieden said. The estimate was based on a survey of commercial lab data that found about 58% of Americans had antibodies as a result of a Covid infection. The more than 21 million additional confirmed cases on top of the CDC's February estimate of about 187 million total infections gives a low-end estimate of more than 208 million infections since the pandemic began.

☆ China's people are protesting the country's severe zero-COVID policies, and public-health experts agree with them

Protests are erupting across China over the country's restrictive zero-COVID policies. Public-health experts say the policies are unsustainable, ineffective, and unnecessarily severe. Without vaccination campaigns targeting older adults, China's lockdowns may only delay a catastrophic COVID wave. Tyrone Siu/ReutersThere is no easy way forward for China, but constant 2020-style lockdowns are not the solution, according to public-health experts, who called the policies unsustainable, ineffective, and irrational. As a result, Huang thinks the zero-COVID lockdowns are completely unwarranted.

But it still refuses to use Western mRNA vaccines to innoculate the population more quickly. China's hesitancy to use Western vaccine technology is contributing to the mass protests against its COVID-19 restrictions. Despite that, China is still refusing to approve and distribute Western vaccines to innoculate its citizens. In lieu of the Western vaccines, which are based on mRNA, China has been relying on its own brand of jabs, which rely on inactivated, or killed, virus. Germany this week suggested China should use Western vaccines to speed up the process and protect the country from the virus, Politico reported.

Flu cases are already rising in parts of the U.S., according to the Centers for Disease Control and Prevention. The convergence of viruses is hitting health care systems as they're forced to reckon with staffing shortages that worsened during the pandemic. Staffing deficits mean there is little wiggle room to accommodate any additional surges of patients, whether they're sick with Covid, flu or other illness. But as the cold weather sets in and people increasingly gather indoors, Covid cases are expected to rise. The vast majority of Covid cases circulating now are an omicron subvariant, BA.5.
