It was only 12 day earlier, on January 8, that the World Health Organization (WHO) said the bizarre pneumonia sickening people in China was likely caused by an altogether new virus. Chinese authorities have notified the WHO of a cluster of unexplained illnesses on December 31. The virus was isolated and its genetic makeup was sequence by January 7. At that time, both the Chinese government and [https://www.kynghidongduong.vn/tours/tour-thai-lan-bangkok-pattaya-5-ngay.html tour thái lan] the WHO were urging calm, insisting that the virus was only spreading from people who had symptoms and did not pose a major threat to people outside China's Hubei Province. Even the first case identified in the U.S. - in a Washington state man who had recently returned from China - was not an indication that coronavirus was going to take hold in the U.S., [https://www.kynghidongduong.vn/tours/tour-thai-lan-bangkok-pattaya-5-ngay.html tua du lịch thái lan] officials said at the time. We now know that it already was taking hold. Previous genetic sequencing studies have shown that coronavirus was likely already on both coasts of the U.S. by mid- to late-January, starting to circulate in broader communities in February. But testing of blood donated to the Red Cross confirms what the studies of coronavirus genomes suggested: COVID-19 was here, long before Americans knew it. The new study, published in the journal Clinical Infectious Diseases, tested samples from 7,389 blood donations for antibodies to the virus. Antibodies were present in 106 - 1.4 percent - of the donations collected between mid-December and [https://www.kynghidongduong.vn/tours/tour-thai-lan-bangkok-pattaya-5-ngay.html tour thái lan] mid-January. The use of antibodies to assess how prevalent the virus is has been questioned. Antibodies fade over time, with some studies suggesting that they become undetectable within two or three months of infection. There is also the possibility that blood could react to testing if someone had antibodies to one of the hundreds of other types of coronaviruses in the environment. But 90 of the Red Cross samples were tested for antibodies very specific to SARS-CoV-2 - immune proteins that the scientists had made sure were not cross-reactive with test for other coronaviruses. Of the 90, 84 samples were positive for these very specific antibodies. In the batch of samples taken from later blood donations - made between December 17 and December 30, the scientist found that 67 were positive for coronavirus antibodies. These [http://www.empowher.com/search/site/samples samples] came from donors in Massachusetts, Michigan, Wisconsin or Iowa and [http://search.usa.gov/search?affiliate=usagov&query=Connecticut Connecticut] or Rhode Island. So not only was coronaviru already on the West Coast before the first U.S. case was confirmed there, it was already in states on the other side of the country before the Washington patient was identified. President Trump was perhaps the most promise voice in a chorus that blamed China for 'covering up' the severity of the coronavirus outbreak in the early days of the pandemic's global spread. China's Communist Party has a poor track record for disease outbreaks and transparency. <div class="art-ins mol-factbox health" data-version="2" id="mol-b6d07180-341a-11eb-8974-6f898e53e517" website was spreading in the US by December 17, study finds

By Laurie Goering LONDON, Nov 30 (Thomson Reuters Foundation) - When the coronavirus pandemic hit early this year and countries began competing for a limited global supply of medical masks and other protective equipment, Finland didn't join the hunt. Instead it turned to its national stockpile of medical gear and food, which it had developed during the Cold War era and maintained with an annual budget, [https://www.kynghidongduong.vn/tours/tour-thai-lan-bangkok-pattaya-5-ngay.html tour thái lan giá rẻ] even as [http://data.gov.uk/data/search?q=Scandinavian%20neighbours Scandinavian neighbours] like Sweden had dismantled their stores to cut costs. "Finland could just open its closet and supply all the hospitals - and Sweden was chasing (equipment) on the market," said Johan Rockstrom, Swedish co-director of the Potsdam Institute for Climate Impact Research, based in Germany. As the world faces increasingly frequent and severe shocks - from the COVID-19 pandemic to extreme weather linked to climate change - it will need to re-evaluate its priorities, from a focus on efficiency to the value of interconnectedness, [https://www.kynghidongduong.vn/tours/tour-thai-lan-bangkok-pattaya-5-ngay.html tour thái lan giá rẻ] he said. That might extend as far as fundamentally rethinking how key planetary life-support systems - such as the fast-disappearing Amazon rainforest - are governed as a global resource, said Rockstrom, an earth scientist and leading thinker on resilience. "If the Amazon rainforest crashes, we will lose jobs in Germany," he said. "It will create so much havoc in the climate system" as temperature increases accelerate and rainfall shifts, he warned. "When something unacceptable happens in one corner of the planet, it sends invoices across the whole world," he added. "We cannot allow wet markets that lead to zoonotic mutations and, in the same way, we cannot allow the West Antarctic ice sheet to collapse", raising sea level an estimated 3.3 metres (10 feet) globally, he said. Harnessing a growing ability to digitally monitor what is happening around the world minute-to-minute - using everything from satellite data to mobile-phone tracking systems - could help provide earlier warnings and greater protection for threatened systems, he said. "The next Wuhan" - the Chinese city where the coronavirus pandemic emerged - "should be detected much earlier", he said, noting that the global damage caused by the virus "is exactly what can happen" if the Amazon disappears, driving catastrophic climate change. DIVERSIFY AND DUPLICATE To cope with a growing range of threats, human systems need to become more like healthy natural systems - diverse and [https://www.kynghidongduong.vn/tours/tour-thai-lan-bangkok-pattaya-5-ngay.html tour thái lan] with plenty of duplication, he told the Thomson Reuters Foundation in a telephone interview. In nature, when a fire, drought or disease hits, temporarily or permanently wiping out one plant or pollinator, others usually can take its place, Rockstrom said. "Ecological diversity is a way of reducing risks," he said. "If you want to recover in a resilient way after COVID-19, you likely want to invest in diversity". That could mean, for instance, growing a wider variety of food crops, rather than the current few strains of rice, maize, wheat and soy, to ensure a crop pandemic that hits one variety does not wipe out too much of the global food supply. The same principle could also be applied to ways people make a living - particularly where options today are scarce - and to how they source reliable information, he said. Building stronger resilience also could mean broadening the range of countries that produce key items like computer chips, a lesson learned after major supplier Thailand saw production shut down by flooding in 2011, disrupting supply chains worldwide. "If you have more shocks like that, you want to invest in a certain degree of redundancy - some slack in the system," said Rockstrom, even though that "goes against conventional logic" of running businesses for maximum efficiency and at low cost. Similarly, the value of ever-increasing connectivity may need to be reconsidered in a world where a deadly pandemic can swiftly travel around the world with few barriers. For instance, global connections mean food surpluses in one place can be used to plug shortages elsewhere - but over-reliance on trade can lead to conflict and hunger if exporting countries decide to keep scarce food at home in an emergency. "This balancing of connectivity is fundamental to resilience," Rockstrom said. 'ZERO NATURE LOSS' Perhaps the surest way to boost resilience and cut human risks is to protect the [http://www.cafemom.com/search/index.php?keyword=planet%27s%20imperilled planet's imperilled] natural systems, he said. Already, half of nature on land has been destroyed to make way for agriculture, cities and other human needs, he said. Resources that once felt limitless have become scarce and pressure is rising on what's left. "It seems like we've reached a saturation point on what the planet can cope with," Rockstrom said. That is evidenced in hotter temperatures, melting ice, wilder weather, more forest fires and shifting disease threats, he noted. To change that, scientists are pushing governments to commit to protect 30% of land and oceans by 2030 to help stem climate change and halt biodiversity loss. Doing so would save $5 for each $1 spent in terms of boosting farm and forest yields, improving freshwater supplies, conserving wildlife and fighting planetary warming, economists said in a July paper. "The most clever investment we can make is to keep nature intact," Rockstrom said, calling for a "zero loss of nature" goal alongside emerging net-zero emissions goals. Rethinking how to govern the planet's natural systems - from climate-heating methane locked up in melting Siberian permafrost to Greenland's thinning ice sheets - is a sensitive issue but one that is crucial for humanity's future, he said. "The definition of resilience, at the global level, is to keep the living systems that regulate the state of the planet intact," he added.
