Close to all new COVID-19 <\/a>cases in the United States are now being caused by the JN.1 variant<\/a>, the Centers for Disease Control and Prevention says, with an estimated 93.1% of infections now blamed on the highly mutated strain<\/a>. <\/p>\n\n\n\n

The CDC’s latest biweekly estimate of the variant’s spread was published<\/a> Friday. It comes as key trends reflecting COVID-19’s spread are now showing signs of slowing, following a peak over the winter holidays.<\/p>\n\n\n\n

“Several key indicators are showing decreasing levels of activity nationally,” the agency said<\/a> Friday in its weekly respiratory viruses report. <\/p>\n\n\n\n

Only the South has seen trends of the virus rise in wastewater<\/a> over recent weeks, according to the CDC’s tally through Feb. 1. <\/p>\n\n\n\n

Most parts of the country are also seeing steep slowdowns in COVID-19 cases diagnosed in emergency rooms, except in the South where trends now appear to have roughly plateaued in some states.<\/p>\n\n\n\n

The agency also published<\/a> new data Thursday from its pharmacy testing program that suggests this season’s updated COVID-19 vaccines<\/a> had 49% effectiveness against symptomatic JN.1 infection, among people between two to four months since they got their shot. <\/p>\n\n\n\n

“New data from CDC show that the updated COVID-19 vaccines were effective against COVID-19 during September 2023 \u2013 January 2024, including against variants from the XBB lineage, which is included in the updated vaccine, and JN.1, a new variant that has become dominant in recent weeks,” the CDC said<\/a> in a post on Thursday. <\/p>\n\n\n\n

CDC officials have said that other data from ongoing studies using medical records also offered “early signals” that JN.1’s severity was indeed not worse than previous strains<\/a>. That is a step beyond the agency’s previous statements simply that there was “no evidence” the strain was causing more severe disease. <\/p>\n\n\n\n

The CDC’s new variant estimates mark the culmination of a swift rise for JN.1, which had still made up less than half of infections in the agency’s estimates through late December<\/a>.<\/p>\n<\/div><\/div>","protected":false},"excerpt":{"rendered":"
