Urban white-collar workers pursue taste, but going to work every day is like suffering. Let deep space make small series to give you some psychological comfort. Bian Xiao sorted it out for a long time and brought this article to everyone. Get the melon seeds bench ready and let's go and have a look.

What did the first COVID-19 death in the United States reveal? The health department of Santa Clara County, California, where Silicon Valley is located, issued a statement on Tuesday night, officially confirming that two people who died on February 6 and 17 were infected with COVID-19 virus. This recognition not only advanced the first case of COVID-19 death in the United States by more than three weeks, but also meant that it was necessary to re-examine the spread track of COVID-19 epidemic in the United States.

Zheng Jun from Sina Technology comes from Silicon Valley, USA.

Prior to this, the first COVID-19 death in the United States was an old man in Washington State on February 29th. He was infected with the virus in an elderly care center. The first confirmed case in COVID-19, USA was a young man in Seattle on June 65438+1October 2 1 day, and the first confirmed case in California was a middle-aged man on June 26+June 65438. Both confirmed cases have a travel history in China.

According to this statement from the Santa Clara County Health Department, a 57-year-old woman and a 69-year-old man died at home on February 6th and17th respectively. Because they didn't travel overseas before, they didn't meet the COVID-19 testing standards of the US Centers for Disease Control and Prevention at that time, and they didn't have virus testing before they died. Moreover, their influenza virus test was negative, which ruled out the possibility of influenza.

The suspicious coroner and the health department extracted the tissues of the deceased and contacted the CDC headquarters for confirmation. Although the health department of Santa Clara County sent the samples of the deceased to the CDC in mid-March, it was not until this week that the CDC officially confirmed that they died in COVID-19. If the Silicon Valley health department had not insisted on verification, perhaps none of these deaths would have been confirmed.

After COVID-19's death was confirmed on February 6th, the governor of California yesterday ordered a thorough investigation of all autopsy reports since June 65438+February last year to determine whether there were any cases of COVID-19. The health department of Santa Clara County directly indicated that a large number of COVID-19's bodies are expected to be found, which is just the tip of the iceberg. At present, there are more than a dozen suspected deaths waiting for further investigation.

"These newly discovered cases are all community transmission. We believe that in early February, the virus has spread in a large number of communities in Silicon Valley, or even earlier. It was the flu season, and the COVID-19 test was restricted. It is difficult to distinguish between flu patients and COVID-19 patients. "

Although the health department of Santa Clara County did not disclose too much personal information of the deceased, the American media released some personal information of the deceased with the consent of the deceased's family.

This middle-aged lady named Patricia Dodd lives in the south of San Jose. According to her family, she is healthy, exercises regularly, pays attention to her diet, and has no basic diseases. She developed flu-like symptoms at the end of 5438+ 10. She was once thought to be recovering and still insisted on working at home. At 8 o'clock in the morning of her death, she had a working contact with her colleagues. But two hours later, her daughter found her dead in the kitchen.

When she died, people thought that the direct cause of death was a heart attack, but her family had many doubts about it. Dodd is an auditor of Panlin Group, a silicon valley chip equipment supplier. According to family members, Dodd travels overseas several times a year, including Europe and China. Her last business trip to China was last June165438+1October, and she originally planned to come to China for business trip later this year.

Although she didn't travel in China before her death, there were a large number of overseas travelers in the company where she worked and the community where she lived. Pan-Forest Group was founded by immigrants from China to Lin Jieping. Last year, the revenue was 9.5 billion US dollars, the employees exceeded 654.38 million, and the market value was nearly 40 billion US dollars. As a semiconductor equipment supplier, Marco Lin Group has many businesses in China and branches in China and Shanghai.

However, as the county of santa clara Health Department said, it is impossible to determine the source of Dodd in COVID-19, which is a community-transmitted case. She developed symptoms at the end of 5438+ 10. If the incubation period is reversed, there may have been many cases of COVID-19 infection in Silicon Valley in mid-June, 5438+10. It was the flu season, and there was no COVID-19 test, which made the health department completely ignore the surrounding COVID-19.

It is precisely because the United States did not complete the inspection in time at the end of 1 that a large number of suspected cases were missed, which allowed the virus to spread widely in the community, leading to the emergence of community-transmitted cases at the end of February, which has been unable to effectively flow and control. Where should this responsibility come from?

The two direct regulators, CDC and FDA, are obviously duty-bound. In June, 5438+10/mid-October, the CDC rejected the German-made nucleic acid detection reagent provided by the World Health Organization, and insisted on using the self-developed reagent on June,120 +65438. The FDA delayed the approval of virus testing in other laboratories, resulting in the need to send samples to CDC in Atlanta for testing.

Unfortunately, the first batch of detection reagents sent by CDC to states in early February had to be recalled urgently because of production pollution, which directly delayed the virus detection process in the United States. Until mid-February, the United States could only conduct 100 tests every day. Until March 7, the total number of tests in the United States did not exceed 6,000.

However, the Wall Street Journal quoted an anonymous source as saying yesterday that the superior director of the two institutions and US Health Secretary Azar should be responsible for a series of decision-making mistakes. It was he who asked the CDC to reject the WHO reagent, and he also instructed the FDA to postpone the approval and qualification process of other laboratories.

Santa Clara County, together with other San Francisco Bay Area counties, became the first area in the United States to implement family control on March 16. However, Cody, head of the health department of Santa Clara County, said, "If we can carry out large-scale testing in advance, know the spread of the virus in time, and know that there have been deaths, we should take action earlier."

As of today, in Santa Clara County, Silicon Valley, 1987 people were diagnosed, 95 people died, and the population was 1920000. However, the antibody test of 3,200 residents in Santa Clara County conducted by Stanford University on April 3-4 showed that at least 2.49%-4. 16% of the residents had been infected with COVID-19 virus, equivalent to 48,000 -8. 1 10,000 people, while the number officially confirmed at that time was 956. This means that the actual number of infected people is more than 50 times that of officially diagnosed people.
