A phylogenetic tree based on whole-genome sequences of SARS-CoV-2 and related coronaviruses is: ( Bat ) Rc-o319 , 81% to SARS-CoV-2, Rhinolophus cornutus , Iwate , Japan Bat SL-ZXC21 , 88% to SARS-CoV-2, Rhinolophus pusillus , Zhoushan , Zhejiang Bat SL-ZC45 , 88% to SARS-CoV-2, Rhinolophus pusillus , Zhoushan, Zhejiang Pangolin SARSr-CoV-GX, 85.3% to SARS-CoV-2, Manis javanica , smuggled from Southeast Asia Pangolin SARSr-CoV-GD, 90.1% to SARS-CoV-2, Manis javanica , smuggled from Southeast Asia Bat RshSTT182, 92.6% to SARS-CoV-2, Rhinolophus shameli , Steung Treng , Cambodia Bat RshSTT200, 92.6% to SARS-CoV-2, Rhinolophus shameli , Steung Treng, Cambodia (Bat) RacCS203 , 91.5% to SARS-CoV-2, Rhinolophus acuminatus , Chachoengsao , Thailand (Bat) RmYN02 , 93.3% to SARS-CoV-2, Rhinolophus malayanus , Mengla , Yunnan (Bat) RpYN06 , 94.4% to SARS-CoV-2, Rhinolophus pusillus , Xishuangbanna , Yunnan (Bat) RaTG13 , 96.1% to SARS-CoV-2, Rhinolophus affinis , Mojiang , Yunnan (Bat) BANAL-52 , 96.8% to SARS-CoV-2, Rhinolophus malayanus , Vientiane , Laos SARS-CoV-2 SARS-CoV-1 , 79% to SARS-CoV-2 There are many thousands of variants of SARS-CoV-2, which can be grouped into
7210-439: The revolution. As the revolution spread to other parts of the country, the Qing government concentrated loyalist military forces to suppress the uprising in Wuhan. From October 17 to December 1, the revolutionary army and local volunteers defended the city in the Battle of Yangxia against better armed and more numerous Qing forces commanded by Yuan Shikai . Huang Xing would arrive in Wuhan in early November to take command of
7313-415: The revolutionary army. After fierce fighting and heavy casualties, Qing forces seized Hankou and Hanyang. But Yuan agreed to halt the advance on Wuchang and participated in peace talks , which would eventually lead to the return of Sun Yat-sen from exile, founding of the Republic of China on January 1, 1912. Through the Wuchang Uprising, Wuhan is known as the birthplace of the Xinhai Revolution, named after
7416-523: The role of pangolins as an intermediate host was initially posited (a study published in July 2020 suggested that pangolins are an intermediate host of SARS‑CoV‑2-like coronaviruses ), subsequent studies have not substantiated their contribution to the spillover. Evidence against this hypothesis includes the fact that pangolin virus samples are too distant to SARS-CoV-2: isolates obtained from pangolins seized in Guangdong were only 92% identical in sequence to
7519-526: The secretary of Mao, said that Wuhan Conference was a supplement to Chengdu Conference. As the Third Front campaign shifted the focus of industrial development to China's hinterlands, Wuhan's development slowed. In July 1967, civil strife struck the city in the Wuhan Incident ("July 20th Incident"), an armed conflict between two hostile groups who were fighting for control over the city at
7622-509: The source of a majority of infections. That may explain how out of 217 on board a cruise liner that docked at Montevideo , only 24 of 128 who tested positive for viral RNA showed symptoms. Similarly, a study of ninety-four patients hospitalized in January and February 2020 estimated patients began shedding virus two to three days before symptoms appear and that "a substantial proportion of transmission probably occurred before first symptoms in
7725-558: The source. For a virus recently acquired through a cross-species transmission, rapid evolution is expected. The mutation rate estimated from early cases of SARS-CoV-2 was of 6.54 × 10 per site per year. Coronaviruses in general have high genetic plasticity , but SARS-CoV-2's viral evolution is slowed by the RNA proofreading capability of its replication machinery. For comparison, the viral mutation rate in vivo of SARS-CoV-2 has been found to be lower than that of influenza. Research into
7828-542: The ti-yong ideal. He set up many heavy industries, founded Hanyang Steel Plant, Daye Iron Mine, Pingxiang Coal Mine and Hubei Arsenal and set up local textile industries, boosting the flourishing modern industry in Wuhan. Meanwhile, he initiated education reform, opened dozens of modern educational organizations successively, such as Lianghu (Hunan and Hubei) Academy of Classical Learning, Civil General Institute, Military General Institute, Foreign Languages Institute and Lianghu (Hunan and Hubei) General Normal School, and selected
7931-585: The tower, which had been last destroyed in 1884. During the 1989 Tiananmen Square protests , students in Wuhan blocked the Yangtze River Railway bridge and another 4,000 gathered at the railway station. About one thousand students staged a railroad 'sit-in'. Rail traffic on the Beijing-Guangzhou and Wuhan-Dalian lines was interrupted. The students also urged employees of major state-owned enterprises to go on strike. The situation
8034-745: The towns of Wuchang, Hankou , and Hanyang into Wuhan City, called "Capital District". The new national government, later known as " Wuhan nationalist government ", was based in the Nanyang Building in Hankou, while the central party headquarters and other organizations chose their locations in Hankou or Wuchang. In March 1927, Mao Zedong appeared at the Third Plenum of the KMT Central Executive Committee in Wuhan, which sought to strip General Chiang of his power by appointing Wang Jingwei leader. The first phase of
8137-449: The two major cities on the banks of the Yangtze River that make up the Wuhan metropolis: "Wu" refers to the city of Wuchang ( Chinese : 武昌 ), which lies on the southern bank of the Yangtze, while "Han" refers to the city of Hankou ( Chinese : 汉口 ), which lies on the northern bank of the Yangtze. "Hankou" means "Mouth of the Han", from its position at the confluence of the Han with
8240-516: The uprising at the engineering barracks of Hubei New Army . They then led the New Army of all barracks to join the revolution. Under the guidance of Wu Zhaolin, Cai Jimin and others, this revolutionary army seized the official residence of the governor and government offices. Rui Cheng fled in panic into the Chuyu ship. Zhang Biao, the commander of the Qing army, also fled the city. On the morning of
8343-407: The uprising, beadroll and the revolutionaries’ official seal fell into the hands of Rui Cheng, the governor-general of Hunan and Hubei, who demolished the uprising headquarters the same day and set out to arrest the revolutionaries listed in the beadroll. This forced the revolutionaries to launch the uprising earlier than planned. On the night of October 10, the revolutionaries fired shots to signal
8446-598: The victims. During the Second Sino-Japanese War and following the fall of Nanking in December 1937, Wuhan had become the provisional capital of China's Kuomintang government, and became another focal point of pitched air battles beginning in early 1938 between modern monoplane bomber and fighter aircraft of the Imperial Japanese forces and the Chinese Air Force , which included support from
8549-498: The virus RaTG13 , collected in bats in Mojiang , Yunnan, China to be the closest to SARS‑CoV‑2, with 96.1% resemblance. None of the above are its direct ancestor. Bats are considered the most likely natural reservoir of SARS‑CoV‑2. Differences between the bat coronavirus and SARS‑CoV‑2 suggest that humans may have been infected via an intermediate host; although the source of introduction into humans remains unknown. Although
8652-550: The virus became pathogenic before or after the spillover event . Because many of the early infectees were workers at the Huanan Seafood Market , it has been suggested that the virus might have originated from the market. However, other research indicates that visitors may have introduced the virus to the market, which then facilitated rapid expansion of the infections. A March 2021 WHO-convened report stated that human spillover via an intermediate animal host
8755-484: The virus is infectious during the incubation period is uncertain, but research has indicated that the pharynx reaches peak viral load approximately four days after infection or in the first week of symptoms and declines thereafter. The duration of SARS-CoV-2 RNA shedding is generally between 3 and 46 days after symptom onset. A study by a team of researchers from the University of North Carolina found that
8858-587: The virus may be airborne as well, with aerosols potentially being able to transmit the virus. During human-to-human transmission, between 200 and 800 infectious SARS‑CoV‑2 virions are thought to initiate a new infection. If confirmed, aerosol transmission has biosafety implications because a major concern associated with the risk of working with emerging viruses in the laboratory is the generation of aerosols from various laboratory activities which are not immediately recognizable and may affect other scientific personnel. Indirect contact via contaminated surfaces
8961-422: The virus. Another case study described a 25-year-old man from Nevada who tested positive for SARS‑CoV‑2 on 18 April 2020 and on 5 June 2020 (separated by two negative tests). Since genomic analyses showed significant genetic differences between the SARS‑CoV‑2 variant sampled on those two dates, the case study authors determined this was a reinfection. The man's second infection was symptomatically more severe than
9064-440: Was a political shift made on July 15, 1927, by Wang Jingwei towards Chiang Kai-shek, and his Shanghai -based rival in the Kuomintang. The Wuhan Nationalist Government was established in Wuhan on February 21, 1927, and ended by August 19, 1927. After the end of the Northern Expedition, Hankou was elevated to a centrally-controlled municipality. In the 1931 China floods , one of the deadliest flood disasters in world history, Wuhan
9167-478: Was a refuge for flood victims from outlying areas, who had been arriving since the late spring. But when the city itself was inundated in the early summer, and after a catastrophic dike failure just before 6:00 AM on July 27, an estimated 782,189 urban citizens and rural refugees were left homeless. The flood covered an area of 32 square miles and the city was flooded under many feet of water for close to three months. Large numbers gathered on flood islands throughout
9270-414: Was an important base for Japanese operations in China. On December 18, 1944, in a planned strategic move, and as revenge for the torture and execution of three captured American pilots by Japanese soldiers in the city, Wuhan was bombed by 77 American bombers with the approval of Chiang Kai-Shek. This set off a firestorm that destroyed much of the military resources of the city. For the next three days, Wuhan
9373-566: Was bombed by the Americans, destroying all of the docks and warehouses of Wuhan, as well as the Japanese air bases in the city. The air raids also killed thousands of Chinese civilians. "According to casualty statistics compiled by Hankou city in 1946, more than 20,000 were killed or injured in the December bombings of 1944." Wuhan returned to Chinese control in September 1945. Administratively, Wuchang and Hanyang were initially combined into
9476-469: Was confirmed on 20 January 2020 during the COVID-19 pandemic . Transmission was initially assumed to occur primarily via respiratory droplets from coughs and sneezes within a range of about 1.8 metres (6 ft). Laser light scattering experiments suggest that speaking is an additional mode of transmission and a far-reaching one, indoors, with little air flow. Other studies have suggested that
9579-800: Was constructed on the Wuchang side of the Yangtze River by order of Sun Quan , leader of the Eastern Wu . The tower became a sacred site of Taoism . Due to tensions between the Eastern Wu and Cao Wei kingdoms, in the autumn of 228, Cao Rui , grandson of Cao Cao and the second emperor of the state of Cao Wei , ordered the general Man Chong to lead troops to Xiakou ( 夏口 ; in present-day Wuhan). In 279, Wang Jun and his army conquered strategic locations in Wu territory such as Xiling (in present-day Yichang , Hubei), Xiakou ( 夏口 ; present-day Hankou) and Wuchang ( 武昌 ; present-day Ezhou , Hubei). During
9682-452: Was discharged on 15 April 2020 after two negative tests, and tested positive again on 15 August 2020 (142 days later), which was confirmed by whole-genome sequencing showing that the viral genomes between the episodes belong to different clades . The findings had the implications that herd immunity may not eliminate the virus if reinfection is not an uncommon occurrence and that vaccines may not be able to provide lifelong protection against
9785-556: Was in turn conquered by Qin in 223 BC. During the Han dynasty , Hanyang became a fairly busy port. The Battle of Xiakou in AD ;203 and Battle of Jiangxia five years later were fought in the region over control of Jiangxia Commandery , territories of which included much of present-day eastern Hubei. In the winter of 208/9, one of the most famous battles in Chinese history and
9888-454: Was no escape – they died by the tens of thousands. ... I was just coming off duty at the company's main office, a fairly new three-story building near the center of town ... When I heard the terrible noise and saw the wall of water coming, I raced to the top story of the building. ... I was in one of the tallest and strongest buildings left standing. At that time no one knew whether the water would subside or rise even higher. The high-water mark
9991-433: Was planning to attack Hou, but this drew Xiao Yi's ire—believing that Xiao Guan was intending to contend for the throne—and he sent Wang to attack Xiao Guan. In summer 567, Chen Xu commissioned Wu Mingche as the governor of Xiang Province and had him command a major part of the troops against Hua, along with Chunyu Liang ( 淳于量 ). The opposing sides met at Zhuankou ( 沌口 , in modern Wuhan). The city has long been renowned as
10094-509: Was reached on August 19 at Hankou, with the water level exceeding 16 m (53 ft) above normal. In 1936, when natural disaster struck Central China with widespread flooding affecting Hebei , Hunan , Jiangxi , Wuhan and Chongqing caused by the Yangtze and Huai Rivers bursting their banks, Ong Seok Kim , as Chairman of the Sitiawan Fundraising and Disaster Relief Committee, raised money and materials in support of
10197-594: Was so tense that residents reportedly began a bank run and resorted to panic-buying. Wuhan was the first stop on Deng Xiaoping 's 1992 southern tour . In the wake of the United States bombing of the Chinese embassy in Belgrade on May 7, 1999, protests broke out throughout China, including in Wuhan. On June 22, 2000, a Wuhan Airlines flight from Enshi to Wuhan was forced to circle for 30 minutes due to thunderstorms. The aircraft eventually crashed on
10300-496: Was suggested that the acquisition of the furin-cleavage site in the SARS-CoV-2 S protein was essential for zoonotic transfer to humans. The furin protease recognizes the canonical peptide sequence R X[ R / K ] R ↓X where the cleavage site is indicated by a down arrow and X is any amino acid . In SARS-CoV-2 the recognition site is formed by the incorporated 12 codon nucleotide sequence CCT CGG CGG GCA which corresponds to
10403-597: Was the most likely explanation, with direct spillover from bats next most likely. Introduction through the food supply chain and the Huanan Seafood Market was considered another possible, but less likely, explanation. An analysis in November 2021, however, said that the earliest-known case had been misidentified and that the preponderance of early cases linked to the Huanan Market argued for it being
10506-479: Was the site of the Battle of Wuhan . On December 31, 2019, SARS-CoV-2 , a novel coronavirus that later caused the COVID-19 pandemic , was first discovered in Wuhan and the city was the location of the first lockdown of the pandemic in January 2020. Wuhan is considered the political, economic, financial, commercial, cultural, and educational center of Central China. It is a major transportation hub, with dozens of railways, roads, and expressways passing through
10609-527: Was under the administration of the local government in Hanyang , although it was already one of the four major national markets ( zh:四大名镇 ) of the Ming dynasty. Hanyang's Guiyuan Temple was completed in the 15th year of Shunzhi (1658). By the dawn of the 18th century, Hankou had become one of China's top four trading centers. In the late 19th century, railroads were extended on a north–south axis through
