CDC: Most COVID-19 cases in New York City in March traced to Europe

July 16 (UPI) -- Up to 75% of the coronavirus strains circulating in New York City in early March shared genetic similarities with those seen in Europe and other areas of North America, according to an analysis published Thursday by the U.S. Centers for Disease Control and Prevention.

 

The findings are significant, given that they are based on samples of the new coronvirus, SARS-CoV-2, collected from patients at five hospitals in the city selected intentionally because "of their high use" by people who are "self-identified Chinese speakers," the agency researchers said.

COVID-19 is the disease caused by infection with the new coronavirus.

 

Samples tested in the study were gathered in early March at the start of the outbreak in New York, researchers said, and the hospitals were chosen "because of concern that SARS-CoV-2 could be introduced by travelers returning from China, where the outbreak originated."

"One of the major reasons why New York City was such an epicenter [for COVID-19] early on is [air travel]," William Hanage, associate professor of epidemiology at Harvard T.H. Chan School of Public Health, said during a conference call with reporters Wednesday.

 

"There were lots of flights going [to New York airports] from all over the world, including Europe," said Hanage, who was not part of the CDC analysis.

 

The U.S. government restricted travel from China on Feb. 2, more than a month after the COVID-19 outbreak was first identified in the city of Wuhan, the CDC researchers noted.

Travel from Europe was restricted on March 13, they said.

 

The 544 samples used in the new analysis were collected at New York City hospitals between March 1 and March 20, according to the researchers.

 

In all, 36 -- or 6.6% -- tested positive for COVID-19, including 14 -- or 12% -- among 119 children aged 18 years and under, they said.

Full genome sequences were generated from the 36 positive samples of the coronavirus, the researchers said.

 

In addition to the 27 samples "largely dominated by [genetic] sequences detected in Europe and other areas of North America, two samples featured genetic sequences similar to those found in cases in Washington state and seven shared similarities with samples collected in China or other parts of New York state," they said.

 

The findings of the CDC analysis are similar to those of a study published in June by the journal Science, which found that virus samples collected from 84 patients in New York City between March 9 and March 14 could be traced to cases in Europe and other parts of the United States.

 

A similar analysis, also published by Science in June, found at least seven different strains of the coronavirus circulating in California, which suggested that outbreaks there likely originated from several sources, including overseas travelers and from visitors from other U.S. states, the authors said.

Doing additional genetic sequencing of the samples, the strain of the virus more closely resembled the one circulating in Europe, rather than the one circulating in China. That means that the novel coronavirus was likely introduced to New York through Europe or by travelers from other US locations, the report said.

“Mount Sinai issued a report earlier that found the virus that came to New York had come from Europe and not from China,” Cuomo said during a conference call on Thursday, July 16. “They did that by studying the genetic makeup of the virus, and when the virus had gone from China to Europe, the virus mutated in Europe, and the viral strain that came to New York was from Europe.


“The report they just put up says, that although travel restrictions are an important mitigation strategy, by the time the European restrictions were implemented, importation and community transmission had already occurred in New York.”

CNN reported in April that two separate research projects started earlier this year also suggested as much, also suggesting the virus may have been circulating in the city earlier than thought.

Pada tanggal 16 juli (UPI) — menurut sebuah analisis yang dirilis pada hari kamis di pusat penyakit as, pada awal bulan maret sebanyak 75 persen dari sampel virus koroner yang beredar di new york city memiliki kemiripan genetik yang sama dengan bagian-bagian lain eropa dan amerika utara. Kontrol dan pencegahan.

Temuan ini penting karena didasarkan atas sampel virus baru berupa SARS- cov-2, yang telah dikumpulkan dari lima rumah sakit di kota itu, yang para pasien ini telah dipilih dengan sengaja karena orang-orang yang "diidentifikasi sebagai orang cina" "banyak menggunakan juru bicara".



COVID-19 adalah penyakit akibat infeksi virus baru.

Para peneliti mengatakan bahwa sampel yang diuji dalam penelitian ini telah dikumpulkan pada awal wabah di new york pada awal bulan maret, dan rumah sakit ini telah dipilih karena "khawatir bahwa SARS- cov-2 dapat diperkenalkan oleh para wisatawan yang kembali dari wabah cina. Asal."

Warga amerika yang terkait membuat rekor harian baru untuk kasus COVID 19, 67.400
William Hanage, lektor kepala epidemiologi di universitas kesehatan masyarakat chen di harvard, menyatakan, "salah satu alasan utama mengapa kota new york begitu awal menjadi pusat gempa [bagi COVID — 19] adalah [perjalanan melalui udara]," bersama reporter pada hari rabu.

"Ada banyak penerbangan dari seluruh dunia [termasuk eropa] ke bandara new york," kata hannag.

Para peneliti CDC menyatakan bahwa pemerintah as membatasi perjalanan dari cina pada tanggal 2 februari, setelah lebih dari sebulan setelah mereka pertama kali terdeteksi wabah COVID 19 di kota wuhan.

Strain perkembangan virus terkait yang bermutasi membuatnya lebih menular
Mereka mengatakan, perjalanan dari eropa dilarang pada 13 maret.

Antara tanggal 1 dan 20 maret, para peneliti mengatakan bahwa 544 sampel yang digunakan untuk analisis baru dikumpulkan di rumah sakit new york city.

Mereka mengatakan bahwa total 36 orang (yaitu 6.6%) yang telah menjalani tes positif, 14 (atau 12%) dari 119 anak di bawah usia 18 tahun.

Pejabat kota new york yang bersangkutan berencana melakukan program pelacakan pengguna cvid 19 berskala besar
Menurut para peneliti, urutan lengkap genom muncul dari 36 sampel positif virus koroner.

Selain 27 dari "contoh utama" yang ditemukan di berbagai bagian eropa dan amerika utara lainnya, ada dua yang memiliki urutan hereditas yang mirip dengan kasus negara bagian washington, dan tujuh sampel yang sama dengan sampel yang dikumpulkan di cina atau di tempat lain." Kata mereka.

Hasil analisis CDC mirip dengan hasil penelitian yang diterbitkan dalam majalah science pada bulan juni, yang menemukan bahwa antara 9 dan 14 maret, 84 sampel virus yang dikumpulkan dari sejumlah pasien di new york city dapat ditelusuri kembali ke kasus di amerika serikat di eropa dan di tempat-tempat lain.

Analisis serupa, kata kelompok itu, juga diterbitkan pada bulan juni oleh majalah science dan mendapati bahwa sedikitnya tujuh virus positif menyebar di kalifornia, menunjukkan bahwa wabah di sana mungkin berasal dari berbagai sumber, termasuk para pengunjung dari luar negeri dan di negara-negara bagian lain amerika serikat.

纽约市将于周一开始其第四阶段的重新开放,这将允许购物中心和文化机构重新开放,但 室内运营将保持关闭在周四早些时候的一次新闻发布会上,库莫表示,随着该州准备迎接来自西方和南部爆发性疫情的州的第二次冠状病毒感染浪潮,他将加强规定。
