According to a comprehensive report from China News Service, July 21, relevant officials said that on the 19th local time, a senior aide to the Speaker of the House of Representatives Pelosi and a White House official tested positive for the new crown. The two had previously participated in the same event.

On the other hand, the delta variant strain is spreading rapidly in the United States, and American infectious disease expert Fauci said that this variant has unprecedented infectious power.

　　Officials said that both had been vaccinated against the new crown, the symptoms were mild, and they had not had close contact with US President Biden or Pelosi.

But these cases show that Americans who have been vaccinated may still be infected and spread the new crown virus, and Congress and White House officials are not immune.

　　On the 20th local time, Pelosi’s deputy chief of staff Hamill confirmed that a senior spokesperson from the Speaker’s Office was diagnosed on the 19th.

Just a few days ago, the senior spokesperson met with a group of Democratic officials from Texas who went to Washington, D.C., to try to prevent a new election law promoted by Texas Republicans from being passed in the state.

　　Hamill said the spokesperson has been fully vaccinated and has not been exposed to Pelosi since his diagnosis.

　　He said in a statement on the 20th: "Except for those who have not been in contact with this person or who have recently tested negative, the entire press office is working remotely. Our office will continue to closely follow the guidance of the Office of the Attending Physician of the House of Representatives. "

　　The confirmed incident also sounded the alarm on Capitol Hill.

　　On the 20th local time, Pelosi, her assistants and security personnel walked into a closed party caucus meeting wearing masks.

Dozens of aides, reporters and other staff in the Capitol also wore masks.

In the past few weeks, Pelosi has not worn a mask in most cases.

　　In addition, the COVID-19 detection point set up in the basement of the Capitol has been lined up for the first time in a few weeks.

　　At the same time, the White House also confirmed that the confirmed White House staff had never had close contact with senior White House officials.

Last week, this staff member and Pelosi’s assistant attended the same event in Washington, DC, welcoming Democrats from Texas.

　　A White House official said: “The White House is ready to conduct periodic testing for breakthrough cases. This reminds us again that the new crown vaccine can effectively prevent severe illness or hospitalization. We hope that our colleagues can recover as soon as possible.”

　　Among the more than 40 Texas Democrats who went to Washington, DC, several have been diagnosed with the new crown. During their stay in Washington, they met with the Democrats of the United States Congress and the Vice President of the United States.

　　As the more contagious delta variant spreads across the United States, the number of new crown cases across the United States is on the rise, especially in unvaccinated communities.

Experts warn that people who have been vaccinated may still be infected with the new coronavirus, but the vaccine reduces their risk of severe illness and death.

　　According to the "New York Times" report, the United States reported about 35,000 new confirmed cases on the 19th, an increase of nearly 200% from two weeks ago.

　　The Director of the Centers for Disease Control and Prevention (CDC) Valensky said on the 20th that the Delta variant strain accounted for 83% of all newly sequenced new coronavirus cases in the United States.

In the past week, the number of deaths from the new crown in the United States has increased by nearly 48%, with an average of 239 new deaths every day.

　　American infectious disease scientist Fauci said that the Delta variant strain is unprecedented in infectiousness.

But he also added that several new coronavirus vaccines that have been authorized for emergency use in the United States are still highly effective against the variants.
