ເລື່ອງຕົ້ນກໍາເນີດຂອງຫ້ອງທົດລອງ Covid ໄດ້ມາຈາກ 'ທິດສະດີສົມຮູ້ຮ່ວມຄິດ' ກັບການໂຕ້ວາທີຂອງລັດຖະບານ

ເດືອນ​ທັນ​ວາ 2019A ກຸ່ມ of cases of a mysterious respiratory disease were reported in the Chinese city of Wuhan, the first traces of a virus that would kill millions of people worldwide in the worst pandemic in decades.

ກຸມ​ພາ 16​, 2020Sen. Tom Cotton (R-Ark.) becomes ຫນຶ່ງໃນຄັ້ງທໍາອິດ high-profile politicians to tout the theory that the coronavirus originated in a lab setting, either as an artificially created virus or as a natural virus that accidentally leaked out, an idea that broke with the predominant theory that the virus circulated in bats and was naturally transferred from animals to humans through a food market in Wuhan (Cotton acknowledged at the time he didn’t have evidence the virus emerged from a lab).

ມີນາ 7, 2020A group of scientists sign ຈົດຫມາຍເປີດ condemning the “conspiracy theories suggesting that COVID-19 does not have a natural origin”; this letter is later scrutinized, as one of its signers, Peter Daszak, is the head of EcoHealth Alliance, a group that has does work in China at the Wuhan Institute of Virology, which some saw as a conflict of interest.

ເມສາ 18, 2020Then-President Donald Trump, who frequently refers to Covid-19 as the “China virus,” says “a lot of people are looking” into the possibility of a lab leak, and says the theory “seems to make sense”; Dr. Anthony Fauci, then the government’s leading infectious disease expert, ປະຕິເສດ Trump’s claim, citing a study that found the virus’ mutations are “consistent with a jump of a species from an animal to a human.”

ມັງກອນ 15, 2021In the final days of Trump’s presidency, the State Department publishes a ເອກະສານຄວາມຈິງ stating the U.S. government believes that some researchers at the Wuhan Institute of Virology—a biolab whose research into bat viruses had drawn scrutiny—became sick in the fall of 2019, shortly before the outbreak of the Covid-19 pandemic; in May, it is ລາຍງານ that three researchers were hospitalized before the first coronavirus case was reported.

ກຸມ​ພາ 9​, 2021A team from the World Health Organization investigating the source of Covid-19 ເວົ້າວ່າ it is unable to discern its origins, but calls the possibility that the virus escaped from a lab in Wuhan “extremely unlikely”—though many observers questioned whether China gave the team enough access to reach a firm conclusion, and the new Biden Administration expressed “deep concerns” about the report.

ກຸມ​ພາ 9​, 2021A paper in the journal ລັກສະນະ ສະແດງໃຫ້ເຫັນ a close relative of SARS-CoV-2—the virus that causes Covid-19—was found in bats in Thailand, lending credibility to the theory that the virus evolved naturally and was not manipulated in a laboratory.

ອາດ 14, 2021A group of scientists publish an ເປີດຈົດຫມາຍ ໃນວາລະສານ ວິທະຍາສາດ, saying that “we must take hypotheses about both natural and laboratory spillovers seriously until we have sufficient data,” and arguing the lab leak possibility hasn’t been thoroughly investigated.

ອາດ 26, 2021ປະທານາທິບໍດີ Joe Biden ຄໍາສັ່ງ an intelligence review of the two predominant Covid-19 origin theories.

ມິຖຸນາ 3, 2021Fauci, who up until this point has been steadfast that Covid-19 evolved through natural means, ເວົ້າວ່າ “the most likely origin is from an animal species to a human but I keep an absolutely open mind that there may be other origins,” adding, “it could have been a lab leak.”

ເດືອນກໍລະກົດ 20, 2021 Fauci and Sen. Rand Paul (R-Ky.) spar during a Senate hearing, part of a months-long ມີເນື້ອໃນ ການໂຕ້ວາທີ over whether federal agencies funded “gain-of-function” research in China to modify viruses to study their evolutionary growth paths, suggesting (with no direct evidence) the coronavirus might have been created in a lab rather than merely leaking from one; Fauci denied the research method was used, and the National Institutes of Health later said the viruses that were researched were “genetically far distant” from SARS-CoV-2.

ສິງຫາ 25, 2021The intelligence review ordered by Biden does not determine whether Covid-19 emerged from a lab or through natural origins.

ຕຸ​ລາ 29​, 2021A declassified Intelligence Community assessment is ຈັດພີມມາ, stating that China most likely did not develop the virus as a biological weapon, and that most IC analysts have determined with “low confidence” the virus was not genetically engineered; it finds that “two hypotheses are plausible: natural exposure to an infected animal and a laboratory-associated incident.”

ເດືອນກໍລະກົດ 26, 2022A pair of peer-reviewed studies ຈັດພີມມາ ໃນວາລະສານ ວິທະຍາສາດ determine the Huanan Market in Wuhan was the most likely origin of the virus, citing the virus’ likely genetic mutations and the presence of infected people and virus-positive samples near the market.

ຕຸ​ລາ 27​, 2022ສະມາຊິກພັກ Republican ປ່ອຍ a report saying the “most likely” origin of the Covid-19 pandemic was a “research-related incident” at a lab in China, as “critical corroborating evidence of a natural zoonotic spillover” from animals to humans “is missing,” and while “the absence of evidence is not itself evidence,” it is “highly problematic” that a natural origins hasn’t been proven three years into the pandemic.

ກຸມ​ພາ 26​, 2023ໄດ້ Wall Street Journal ແລະ New York Times report the Department of Energy, which oversees networks of U.S. labs, has concluded with “low confidence” that Covid-19 originated in a laboratory.
