中国発の感染力の高い新型コロナ株が米国で入院患者数急増 | N18G
[Music] covid-19 is haunting the world all over. A fresh subvariant of Omicron called NB181 has surfaced and is now making headlines across the globe. First noticed during a spike in cases in China, fueling hospital admissions across the country, the variant has now been detected in the United States through CDC’s airport surveillance program. Chinese hospitals are now reporting a doubling of severely ill patients in just a month, going from 3.3% to 6.3%. In the US, it is already being found across states including California, Washington, Ohio, Rhode Island, and Hubai. The new variants international spread is now confirmed. The CDC’s airport screening program picked up cases in travelers from China, Japan, South Korea, Taiwan, Thailand, Vietnam, France, Spain, and the Netherlands. Samples collected between April and May 2025 showed the virus had made its way to the US via international flyers. Community spread is already underway in several states across the US. Still, despite the spread, there’s been no major surge in hospitalizations in the United States yet. NB181 is a descendant of the Omicron family and seems more transmissible due to its better ability to bind to human cells. However, it does not appear to be more severe, at least not at the moment. Symptoms include persistent low-grade fevers, respiratory issues like sore throat and cough, and gastrointestinal problems such as nausea and appetite loss. Although some patients in the US are also reporting neurological effects like dizziness, headaches, and trouble concentrating. Testing and detection for the new variant remains the same, though many cases go unnoticed unless symptoms become acute. While the CDC continues monitoring the variant, the public health response has taken an unexpected turn. This comes after health secretary Robert F. Kennedy Jr. along with FDA Commissioner Marty McCary and NIH director J Bhachara removed the CO 19 vaccine from the CDC’s recommended schedule for healthy children and pregnant women. RFK Jr. made the announcement via minute long video on X saying the COVID vaccine for healthy children and healthy pregnant women has been removed from the CDC recommended immunization schedule. What sent mixed signals after the announcement was that no CDC officials were part of this video and the agency later redirected all questions back to the Department of Health and Human Services while still continuing its directive on the official website which says and I quote, “If you are pregnant or were recently pregnant, you are more likely to get sick from COVID 19.” So, what’s the reasoning that led to this announcement? Officials argue that current CO strains are milder and the risk-to-benefit ratio for vaccinating healthy kids and pregnant women has changed. But not all experts agree. On X specifically, the announcement has been called reckless, noting that there were no specific scientific data to support such a policy reversal. Since the pandemic began, over 1,300 American children have died from CO and millions of pregnant women were vaccinated without major complications. Critics now fear that this sends the wrong message at the wrong time, especially now when a new variant spreads globally. 5 years ago, the US’s response to CO 19 was marked by lockdowns, mass testing, daily press briefings, and historic vaccine rollouts. Flash forward to 2025, and the approach looks very different. There’s less urgency, less federal coordination, and more individual responsibility. With pandemic fatigue setting in, CO is now being treated as seasonal flu by many. However, public health experts warned that this complacency could come at a cost, especially with faster spreading variants like the NB181. As NB181 tightens its grip on China and now spreads to India, which is another densely populated country, the United States may be on the brink of a renewed challenge. Will the current strategies relying on voluntary testing, selective vaccination, and individual caution hold up? Or is a more robust response needed? Experts urge that an increased genonomic surveillance, clearer public health messaging, and possibly targeted vaccination campaigns if hospitalizations begin to climb in the states. Despite a global surge brewing, the real test for the US does not lie in its preparedness. The real question is will America act before the next corona virus wave becomes a crisis.
A new, highly infectious COVID-19 strain that has led to a spike in hospitalizations in China has now been detected in the US, including cases in New York City, according to the Centers for Disease Control and Prevention.
The new NB.1.81 variant was first detected in the US in late March and early April among international travelers arriving at airports in California, Washington State, Virginia and New York City, with additional cases reported in Ohio, Rhode Island and Hawaii.
The CDC has said there are too few cases in the US to be properly tracked in the agency’s variant estimates, but experts are warning that the virus’ run in China shows it spreads more quickly than other dominant strains of the respiratory infection.
