The N.C. Department of Health and Human Services said in a news release on Tuesday that it's working with the Buncombe and Henderson County health departments to track down additional information. Legionella bacteria can become a health concern when they grow and spread in human-made water systems like hot water tanks, air conditioning systems and other sources that are not properly maintained. State Epidemiologist Dr. Zack Moore said it's not yet known if people attending the fair might have been exposed to Legionella bacteria. Moore says people who attended the fair and are experiencing cough, fever or shortness of breath should call their health care provider right away.
answer:
2 health departments investigate Legionnaires' disease.

question:
As the world mobilizes to battle the virus, China, Hong Kong, Singapore and Taiwan have been relatively successful in curbing the spread so far. But a surge in imported cases in recent days has raised alarm that those efforts could rapidly unravel. "In many countries the number of confirmed cases can be described as explosive," Hong Kong leader Carrie Lam told a press briefing on Tuesday. "If we don't adopt some strict measures...I'm afraid all precaution efforts done in the past two months would be wasted." The latest tally from mainland China, the original epicenter of the coronavirus, showed 21 new confirmed cases on Monday, of which 20 involved infected travelers arriving from abroad, mostly Chinese nationals. Hong Kong said most of the recent confirmed cases in the past two weeks were imported. In Taiwan, 24 new cases up to Tuesday were all imported, while South Korea had 44 new infections involving infected travelers as of Sunday. Singapore confirmed 17 new infections on Monday, its biggest daily jump in cases, with 11 of those imported. The rush to flee virus hotspots in Europe and the United States has pushed up the price of flights. A ticket from London to Hong Kong was going for up to HK$50,000 on Monday night as people tried to get to the city before it imposed tougher restrictions. "It is safer home than in Britain as the policy to contain the outbreak under Boris Johnson is doubtful," said Ling, a Cambridge University student after landing in Hong Kong wearing a surgical mask and rubber gloves. The number of confirmed coronavirus cases in Britain rose to 1,543, up from 1,372 the day before, the health ministry said on Monday. The British death toll rose to 55. Four of Hong Kong's 157 confirmed coronavirus patients have died, while more than 3,200 people have died from the disease in mainland China, the highest number of fatalities. Measures in China, Hong Kong and Singapore, include city-wide lockdowns, border tightening, contact tracing efforts and strict social distancing. The virus has already taken a heavy economic toll, especially in mainland China and global financial hub Hong Kong, so any rise in new cases could be devastating. Hong Kong on Tuesday toughened measures on travelers, requiring 14 days of quarantine for those entering the city as of midnight on Thursday, and joined Singapore in advising against all non-essential travel. China said all inbound, non-transit travelers to Beijing need to be isolated for 14 days at designated quarantine venues, mostly hotels in the city. Macau, the world's biggest gambling hub, on Tuesday banned the entry of all non-residents, a move likely to have a significant impact on the already struggling casino industry. How seriously authorities in Asia take the virus battle has been underscored by punishments meted out or threatened to those who violate quarantine rules or give false information about their whereabouts or travel history. Taiwan said those who do not follow home isolation or quarantine rules could be fined between T$100,000 and T$1 million (US$ 3,300- US$33,000), and has advised people not to travel abroad at all. "We held firm to block the first wave of infection, but a new wave is coming, so everyone should cooperate with disease prevention efforts," Taiwanese Health Minister Chen Shih-chung told a news conference on Monday. While the imported infections in mainland China are still modest in number - 143 cases so far - authorities are concerned that virus carriers could trigger a second wave. The first imported case was reported in late February in the northwestern Ningxia region involving a traveler flying in from Iran. More cases quickly arrived from Iran, a hotspot with nearly 15,000 infections so far, followed by the first infected travelers from Italy in the first week of March. Soon, the infected were spotted on flights from countries including Spain, Britain, France, the Netherlands, Switzerland, the United States, Egypt, Saudi Arabia and the United Arab Emirates. The Philippines, Indonesia and Thailand entered the list this week.
answer:
Asia prepares for coronavirus boomerang wave as residents return home.

Groundskeepers cut the grass on the first fairway following the final practice round for the 2008 Masters golf tournament at the Augusta National Golf Club in Augusta, Georgia, April 9, 2008. REUTERS/Gary Hershorn From log splitters to snow blowers, the $15 billion outdoor power equipment industry sells tens of millions of oil-powered machines a year to U.S. landscapers, loggers, homeowners and a litany of other buyers. While lawn mowers get faster, snow blowers cover more ground and handheld products get lighter, their propulsion has barely changed beyond getting more mileage out of gasoline. This week, at the annual Green Industry and Equipment Expo in Louisville, Kentucky, manufacturers will once again unveil new equipment with some promise of a cleaner, greener future. "We do anticipate the trend moving in the direction of alternative energy," said Jeff Salamon, director of marketing at MTD Products Inc. "Some customers do like the experience of being unencumbered by exhaust and gasoline." However, the answers offered will likely be more of the same. "Gas engines, by and large, are the most efficient way to go," Briggs & Stratton Corp Chief Executive Todd Teske told Reuters in an interview shortly after a press conference to unveil the company's latest engine. Briggs & Stratton sells electric mowers, but only in Australia. For decades, garden and snow machines were a poster child for harmful emissions. In fact, when auto executives were confronted by regulators for their contributions to pollution, they pointed to the lawn industry as a more offensive culprit. In the mid-1990s, that began to change as the Environmental Protection Agency began pressuring engine makers with tougher standards. "These aren't your father's lawn machines," Kris Keiser, president of the Outdoor Power Equipment Institute, said. At Briggs & Stratton, for example, Teske said emissions have been cut by 75 percent since the mid-1990s thanks to manufacturing upgrades and design improvements. Another 35 percent reduction will come in 2012. The auto and other industries are under constant pressure to raise fuel economy or tap new technologies because their customers often burn through dozens or more gallons of gasoline each month. As gas prices rise, so does the strain on pocketbooks. But outdoor equipment users don't face these pressures. "People who use our products typically use no more than five gallons of gasoline per year," Keiser said. This lessens the likelihood that customers will demand huge advances in fuel economy or solutions that lessen their operating expenses. Even commercial landscapers here in Louisville do not seem to be budging, despite high weekly fuel costs. Wang Xiaoguang, general manager of Wenling Leo Garden Machinery Co which claims to be the largest exporter of Chinese garden machines is learning this lesson first hand. Standing at his exhibition booth, he talks about Leo's successful business of exporting electric mowers to Europe. "This customer is different," Wang said of the U.S. market which Leo has yet to crack. "They have different standards." But some companies, including a handful of start-ups, aren't waiting for customers to change their minds. Lincoln Jore, a 28-year-old entrepreneur from Ronan, Montana, launched a new "GasLess" outdoor equipment company called Core Outdoor Power on Thursday aimed at commercial landscapers and higher-end homeowners. His first product, a $249 weed whacker weighing 11 pounds, is powered by an unconventional motor and lithium-ion battery that slips in and out of the machine so it can be charged on a separate dock. It will begin appearing at independent U.S. dealers early next year. The "market has missed the mark on developing alternative energy products that meet performance expectations," he said. By 2013, Jore plans to have a broader range of products, including a lawn mower and leaf blower that don't use gas. But even the most established global players are finding it hard to turn the tide. Honda Motor Co sells thousands of hybrid snow blowers in Japan annually and is bringing a hybrid model to the United States. This model promises to be the Cadillac of its class, capable of clearing 83 tons of snow in an hour and sweep a city sidewalk in one pass. But, at $8,000, this machine is twice as expensive as the company's previous top-of-the-line model, and hybrid technology is driving up the cost. Honda's expectations for sales of the Japan-built hybrid are extremely modest, but it wants to test the market before committing to other alternative-energy models. If Wisconsin-based Ariens Co's experience during last year's tough winter is any indication, there may be hope for Honda. Ariens put on sale an electric snow blower priced 60 percent higher than a conventional model. The company sold out of its limited quantity of electric snow blowers amid heavy snowfall and tight industry capacity. Stihl Inc, which says it is the No. 1 seller of handheld outdoor power devices, is also branching out. It has a new lineup of chainsaws, leaf blowers, weed whackers and hedge trimmers that are powered by lithium-ion batteries. The products cost 30 percent more than conventional gas-powered versions and, while initial demand has outstripped expectations, the company said it is too early to break out specific sales results. Cub Cadet, a brand owned by MTD, has a lithium-ion-powered product line on display similar to those sold by Stihl, but demand so far is only from a "faction" of customers, Salamon said. Still, Cub Cadet is poised for a shift at some point, even if it is slow going, he noted.
answer:
For snow and lawn machines, gasoline remains king.
