The Centers for Disease Control and Prevention is now publicly acknowledging people can be infected with the coronavirus through airborne transmission, especially in enclosed spaces with inadequate ventilation.The update embraces growing evidence and international research showing the coronavirus can linger in the air longer - for minutes and hours - and travel farther than six feet.The update comes two weeks after the official CDC website was updated to reflect this, only to be removed a few days later with the agency saying it was “posted in error” before it was fully reviewed.The draft language seemed to imply aerosol or airborne transmission was the main way the coronavirus spreads, and the CDC says that is not the case.“Infections occur mainly through exposure to respiratory droplets when a person is in close contact with someone who has COVID-19,” the CDC states.Their added section is titled “COVID-19 can sometimes be spread by airborne transmission,” and includes information about smaller particles lingering in the air after an infected person had left the space. "Some infections can be spread by exposure to virus in small droplets and particles that can linger in the air for minutes to hours," it reads.“There is evidence that under certain conditions, people with COVID-19 seem to have infected others who were more than 6 feet away. These transmissions occurred within enclosed spaces that had inadequate ventilation. Sometimes the infected person was breathing heavily, for example while singing or exercising,” the new section on the CDC’s website reads. “These transmissions occurred within enclosed spaces that had inadequate ventilation.”The World Health Organization changed their guidance in July and noted the prevalence of airborne transmission of coronavirus and particles lingering in the air. Hundreds of scientists encouraged the WHO to make the acknowledgement following research and studies. 1943

The fourth nor'easter in three weeks already is closing schools and canceling thousands of flights Wednesday as it's expected to dump record springtime snow in the Northeast.A day after the official beginning of spring, the storm will bring heavy snow, strong winds and even coastal flooding to some areas. It has potential to be one of the most significant and most disruptive snowstorms this late in the season, CNN meteorologists said."If the current forecast pans out, this nor'easter will dump more snow on Washington, Philadelphia and New York than the three earlier storms combined," CNN meteorologist Brandon Miller said.More than 70 million people are under a winter storm watch, warning or advisory from the southern Appalachians to Boston.The storm will move away from the region by Thursday but not without first hitting coastal New England and Maine.Latest developments? More than 4,100 flights are canceled Wednesday due to the storm, according to the tracking site Flightaware.com.? Public schools in New York City, Philadelphia and the District of Columbia are closed Wednesday.? The storm already dumped 13 inches of snow in Greencastle, Pennsylvania, and blanketed Smith Crossroads in West Virginia with 9.2 inches.Snow disrupting nation's capitalWashington will likely see 4 to 6 inches of snow, with some models hinting at much higher totals for the District. Areas west and north of the city are likely to see close to a foot of snow."It's been 75 years since Washington has had 5 inches of snowfall or greater this late in the season," Miller says.Track the storm with high resolution auto-updating graphicsThe inclement weather caused closures for much of the federal government. The White House and State Department canceled all public events for the day. However, the House and Senate are planning to work Wednesday as Congress tries to finalize a spending deal.Philadelphia could see up to a foot of snow. The City of Brotherly Love may get its biggest snowfall after the first day of spring in more than 100 years.For those in other parts of Pennsylvania, the storm was already well underway Wednesday morning. Thile Kreider posted an Instagram video of the snow blanketing her yard in Manheim.New York could break 1958 recordWind gusts and snow reached New Jersey and New York City on Wednesday morning. Ten inches to more than a foot is forecast in the New York City area before the storm departs early Thursday.But Central Park in Manhattan may only receive 4 to 6 inches of snow, CNN meteorologist Chad Myers said, explaining it's more likely snow will accumulate in areas at higher elevations."If New York gets 12 inches of snow -- the National Weather Service currently has a high-end potential of 13 to 21 inches -- it would be its largest snowfall ever recorded after the first day of spring," Miller says.The current record is 11.8 inches, set on March 21, 1958.With these late winter storms, it is difficult to predict snowfall amounts because of the mixing of warmer air. In some of the earlier nor'easters, the air near the ground has stayed warm enough that places like New York have seen lots of snow fall from the sky but had little accumulation. An urban heat island effect is plausible once again with this spring storm.Boston stayed on the warmer side in the first two nor'easters but then got walloped with snow during the third storm this month. The city is likely to see another 6 to 8 inches of snow, adding to the 20-plus inches it has already received in March.If Boston gets 10 inches, the city would have its third snowiest March on record.These late winter storms are likely to become more frequent with climate change. A study last week in the scientific journal Nature Communications ties extreme winter weather, specifically major snowstorms in the Northeast, to warming Arctic temperatures.Blizzard conditions likelyWith a forecast of heavy snow and winds more than 45 mph, blizzard conditions are possible.New York City could see sustained winds of 20 to 30 mph Wednesday, and coastal areas such as Cape Cod in Massachusetts are predicted to receive gusts up to 60 mph from midmorning Wednesday to Thursday.What is makes a snow storm a blizzardFlooding is a threat along the coast from Virginia to Massachusetts. Some of the worst coastal flooding could occur along the Jersey Shore, with high tides of 2 to 3 feet above normal possible.This will put a strain on already vulnerable coastal areas, which saw dramatic storm surges from the nor'easters over the last three weeks.The-CNN-Wire 4555

The erratic stock market just made a serious comeback.Fears about slowing earnings growth sent the Dow careening 549 points lower on Tuesday before the index raced back to life.By the closing bell, the Dow was only down 126 points, or 0.5%.Similarly, the Nasdaq closed down 0.4%, erasing the vast majority of a 2.6% plunge. The index also climbed out of a technical correction, a 10% decline from prior highs.The S&P 500 suffered its fifth straight loss. But the broad index finished just modestly lower after touching its weakest point in nearly four months.Market veterans saw little reason for the dramatic recovery -- other than the fact that stocks had gotten to oversold levels."It was an impressive day. We reversed on very little news," said Art Hogan, chief market strategist at B. Riley FBR.Hogan pointed to how the rebound was led by two of the most beaten-down corners of the market: homebuilders and chip makers.Stocks sold off early on Tuesday after major US companies reported gloomy results and guidance. Disappointing numbers from Caterpillar and 3M reinforced ongoing concerns about how long blockbuster profits can last, especially given tariffs and rising costs."Investors are skittish about whether we've seen a peak in earnings," said Mark Luschini, chief market strategist at Janney Capital Management. "It's a schizophrenic market environment where things that didn't matter suddenly do."It's been a scary month for investors. The Dow and Nasdaq are on track for their worst months since January 2016."The market is fragile," said Rich Guerrini, CEO of PNC Investments. "But we're telling our investors to relax. We're in a correction. I think the market does have some legs left."The CNN Business Fear & Greed Index slipped further into "extreme fear." A month ago the gauge of market sentiment was flashing "extreme greed."Wall Street was also spooked by extreme turbulence in China, the epicenter of the trade war. The Shanghai Composite dropped 2.3% overnight. The sell-off wiped out a chunk of Monday's spike, the benchmark index's best day since March 2016. 2114
