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.

Jose Miguel Cisneros, director of the infectious disease department at Seville's Virgen del Rocio Hospital, on Tuesday announced the first casualty since the outbreak was declared on Aug. 15. Authorities have closed the pork meat supplier's plant and recalled all of its products. Cisneros said roughly half of the 114 people affected by the bacteria remain hospitalized. Health Minister Maria Luisa Carcedo said an investigation is looking into how the meat evaded what she called "strict food safety controls." Listeria is a bacteria that usually causes mild illness in healthy people but can be dangerous to pregnant women and those with weakened immune systems.

Researchers, who studied about 1,000 teens who said they wanted to quit smoking, wrote in the journal Pediatrics that close to 11 percent of those who got counseling for three months had quit smoking, compared to six percent of those who only received educational pamphlets. "A school nurse-delivered smoking-cessation intervention proved feasible and effective in improving short-term abstinence among adolescent boys and short-term reductions in smoking amount and frequency in both genders," wrote study author Lori Pbert of the University of Massachusetts Medical School in Worcester. But a year after the sessions, there was no difference in smoking rates based on what kind of assistance teens had gotten from their nurses. In addition, fewer than one in five teens said they hadn't smoked recently. "It's nice that there was some effect at three months, what we really care about is sustained cessation," said Michael Siegel, who studies tobacco control at the Boston University School of Public health but wasn't involved in the study. "The overwhelming majority of these kids are not quitting." In the 35 Massachusetts schools covered in the study, half the nurses were trained to give their students one-on-one counseling based around goal setting and problem solving, including making a plan to quit and then preventing relapses. The other nurses gave students information pamphlets on quitting smoking and volunteered to answer any questions they had about the process. Both groups of nurses saw their students at four weekly sessions, ranging from 10 to 30 minutes. The counseling intervention appeared to especially help boys in the short run. Those who had made goals and tracked progress with the nurses were three times more likely to say they had stopped smoking than boys in the "control" group. But between 13 and 17 percent of both boys and girls reported they had stopped lighting up a year later, regardless of whether or not they had received counseling. Other smoking cessation experts noted that relapsing into smoking is the biggest hurdle at any age, and that teens were especially likely to do so. But they added that the more options teens had for help, the better. SOURCE: bit.ly/o4z0xc
