Q: 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.

Q: Studying the DNA of two distant bat species, the scientists discovered how genes dealing with the bats' immune system had undergone the most rapid change. This may explain why they are relatively free of disease and live exceptionally long lives compared with other mammals of similar size, such as the rat, said Professor Lin-Fa Wang, an infectious disease expert at the Duke-NUS Graduate Medical School in Singapore who led the multi-centre study. "We are not saying bats never get sick or never get infections. What we are saying is they handle infections a lot better," Wang said in a telephone interview. What was missing from both species of bats was a gene segment known to trigger extreme, and potentially fatal, immune reactions to infections, called the cytokine storm. Cytokine storms end up killing not only offending viruses in the body, but the host's own cells and tissues too. "Viruses rarely kill the host. The killing comes from the host's immune response. So it looks like what bats are doing is depress the inflammation (cytokine storm). If we can learn that, we can design drugs to minimize the inflammation damage and control viral infection," Wang said. The study, which saw the participation of researchers from China, Denmark, Australia and the United States, was published on Friday in the journal Science. Compared with other mammals of similar size, bats live a long time, with lifespans of between 20 and 40 years. Rats live between 2 and 3 years, on average. Interestingly, Wang and his colleagues found that the highly evolved genes that give bats their superior immune system also enable them to fly. Out of more than 5,000 types of mammals on the planet, bats are the only one capable of sustained flight and some species can fly more than 1,000 km in a single night. Such intense physical exertion is known to produce toxic "free radicals" that cause tissue damage and it is these same genes that give the bat the ability to repair itself, Wang said. "What we found was the genes that evolved fastest were genes involved in repairing DNA damage. That makes sense ... because when you fly, metabolism goes up and it generates free radicals that are toxic to cells," Wang said. "Because bats fly, they (would have had) to evolve and adapt ... to get genes that can repair DNA damage." Wang said we have much to learn from the bat, which has evolved to avoid disease and live exceptionally long lives. "Cancer, ageing and infectious disease, these are the three major areas of concern for people," he said. "We have studied rats for 150 years to understand how to do better in these three areas. Now we have a system, the bat, that has done very well in evolution. We can learn from the bat. With modern techniques, we can design new drugs to slow down the ageing process, treat cancer, fight infections."

Q: This is the first time Jammeh has been sued in a Gambian court over alleged abuses during his 22-year rule of this tiny West African nation, the advocacy group AIDS-Free World said. Jammeh's program was "the most egregious premeditated assault on people living with HIV and AIDS in the history of the global AIDS crisis," said Sarah Bosha, the group's legal research and policy associate. Survivors Fatou Jatta, Lamin Ceesay and Ousman Sowe filed the lawsuit at the high court in the capital, Banjul. They seek financial damages and a declaration that their rights were violated. "My experience in the presidential treatment program was a horror," Jatta said in the AIDS-Free World statement. "I could have lost my life." Jammeh in 2007 declared his AIDS "cure" and launched the program, ordering patients to live in a facility and submit to his "treatment regimen" under armed guards' surveillance. The "treatment" included foregoing antiretroviral drugs for an herbal concoction patients said often made them violently ill. Other concoctions were rubbed on them amid chanted prayers, and some sessions were broadcast on Gambian television without patient consent, survivors said. Jammeh forced some 1,000 people, many of them part of HIV/AIDS organizations, to participate before the program was shuttered, and two people died, according to an earlier Amnesty International report. An official with the program, Dr. Tamsir Mbowe, said during testimony to a commission of inquiry in April that 311 patients were treated from 2007 to 2012, according to AIDS-Free World. "The precise number of deaths as a consequence of Jammeh's criminal mistreatment remains difficult to determine," the organization said. "There is no cure for AIDS. When an individual of great power claimed otherwise, human health was jeopardized, lives were cut short and a deadly epidemic was prolonged all in the service of the insatiable ego of Yahya Jammeh," Bosha said. Jammeh has long been accused of human rights abuses during his rule that began after a bloodless coup in 1994. He lost December 2016 elections to now-President Adama Barrow and, after a political standoff, fled into exile to Equatorial Guinea in January 2017. Bosha told The Associated Press that in exceptional situations, "the court can grant an order allowing for civil cases to proceed despite the absence of the defendant, as long as there is sufficient evidence to satisfy the court that the defendant was personally served." Survivors said they hope the former president will be held accountable. "I believe it is my responsibility to hold Jammeh to account," said survivor Ousman Sowe. "I knew that one day the real story would be told." ___ Follow Africa news at https://twitter.com/AP_Africa
