A new study out of a pediatric medical center in Chicago suggests that young children do not only spread COVID-19 more efficiently than adults, but they could be major drivers in the pandemic as schools start to reopen.The report was published at the end of July and examined concentrations of COVID-19 in the nasopharynx, or the upper region of the throat that connects nasal passages. According to the results, children ages 5 and younger who develop mild to moderate symptoms have 10 to 100 times as much COVID-19 in their nasopharynx as adults.“This is a very complex issue involving not just the virus, but everything else,” said Dr. Kwang Sik Kim, director of pediatric infectious disease at Johns Hopkins University Hospital. "We don’t have any real data to indicate to schools what they should do, what is the best recipe they need to follow.”The study raised concerns about the erratic behavior of children and how it could play a factor in the virus’ spread, reading, "Behavioral habits of young children and close quarters in school and daycare settings raise concern for SARS-CoV-2 amplification in this population as public health restrictions are eased. In addition to public health implications, this population will be important for targeting immunization efforts as SARS-CoV-2 vaccines become available.”“Don’t, under any circumstance, even think about opening that school for in-class instruction until you’ve got the virus under control,” said Lily Eskelsen Garcia, president of the National Education Association.Eskelsen Garcia teaches 39 6th-graders in Salt Lake City and says unless the infection rate of a community is below 5 percent, as outlined by the CDC and WHO, school districts should not even consider opening for in-person instruction.Currently, the infection rate in the United States is 7.8 percent."If you open a school before you get the infection rate under control, you will turn that school into the community’s super-spreader,” said Eskelsen Garcia.“Make a decision for today based on the information available today, and then act differently when you have data tomorrow. I think that’s the right approach,” said Dr. Kim. 2170

A Saudi mission that resulted in the apparent death of journalist Jamal Khashoggi in Istanbul was organized by a high-ranking officer with the General Intelligence Presidency, Saudi Arabia's main intelligence service, three sources familiar with the case told CNN.One of those sources described the officer as close to the inner circle of Crown Prince Mohammed bin Salman. It is unclear whether the crown prince authorized an interrogation, abduction or killing. Several officials CNN spoke with said the mission could not have happened without the direct knowledge of the 33-year-old crown prince, the kingdom's de facto ruler, who is known by his initials "MBS."A second source said the officer assembled and sent his own team to interrogate Khashoggi. They suspected Khashoggi of having ties to the kingdom's arch rival, Qatar, the source said. There has been no evidence to substantiate Khashoggi had such ties.Another source told CNN the mission's organizer was not transparent about what he told Riyadh, which, the source said, explained why the government had no clear information for days. 1105

A US Army veteran who served two tours in Afghanistan has been deported to Mexico, US Immigration and Customs Enforcement said.The deportation follows an earlier decision by US authorities to deny Miguel Perez's citizenship application because of a felony drug conviction, despite his service and the PTSD he says it caused.Perez, 39, was escorted across the US-Mexico border from Texas and handed over to Mexican authorities Friday, ICE said in a statement.Perez, his family and supporters, who include Sen. Tammy Duckworth of Illinois, had argued that his wartime service to the country had earned him the right to stay in the United States and to receive mental health treatment for the PTSD and substance abuse."This case is a tragic example of what can happen when national immigration policies are based more in hate than on logic and ICE doesn't feel accountable to anyone," Duckworth said in a statement following reports of Perez's deportation. "At the very least, Miguel should have been able to exhaust all of his legal options before being rushed out of the country under a shroud of secrecy."Perez was born in Mexico and legally came to the United States at age 8 when his father, Miguel Perez Sr., a semi-pro soccer player, moved the family to Chicago because of a job offer, Perez told CNN earlier. He has two children born in the United States. His parents and one sister are now naturalized American citizens, and another sister is an American citizen by birth.It's a complicated case. Perez has said that what he saw and experienced in Afghanistan sent his life off the rails, leading to heavy drinking, a drug addiction and ultimately to his felony conviction."After the second tour, there was more alcohol and that was also when I tried some drugs," Perez said last month. "But the addiction really started after I got back to Chicago, when I got back home, because I did not feel very sociable."In 2010, he was convicted in Cook County, Illinois, on charges related to delivering more than 2 pounds of cocaine to an undercover officer. He was sentenced to 15 years and his green card was revoked. He had served half his sentence when ICE began deportation proceedings. He had been in the agency's custody since 2016.Perez has said he was surprised to be in ICE detention and mistakenly believed that enlisting in the Army would automatically give him US citizenship, according to his lawyer, Chris Bergin. His retroactive application for citizenship was denied earlier this month. While there are provisions for expediting troops' naturalization process, a main requirement is that the applicant demonstrate "good moral character," and the drug conviction was enough to sway the decision against his application, Bergin said.Perez enlisted in the Army in 2001, just months before 9/11. He served in Afghanistan from October 2002 to April 2003 and again from May to October 2003, according to his lawyer. He left the Army in 2004 with a general discharge after he was caught smoking marijuana on base.Perez went on a hunger strike earlier this year, saying he feared deportation would mean death. Aside from not getting the treatment he needs, he told CNN that he fears Mexican drug cartels will try to recruit him because of his combat experience and will murder him if he doesn't cooperate."If they are sentencing me to a certain death, and I am going to die, then why die in a place that I have not considered my home in a long time?" he asked. 3475

A student at Island Park High School in Florida was suspended after the principal and other staff members saw him imitating a gun with his hands and pretending to shoot in a classroom.This happened Friday. "You shouldn't be doing something like that at all," former Island Park High School student Devan Hinton said."It's just not something to be taken lightly," Sam Sherman, who lives in Fort Myers, told Scripps station WFTX in Fort Myers, Florida.The principal called the Lee County Sheriff's Office to file an incident report after he saw the student "imitating a rifle with his hands and pointing it to the classroom."Another staff member described the student making "a gesture with his arm simulating as if he was firing a weapon into the classroom."A third staff member said the student "stood in the classroom doorway and made a machine gun style pose with his arms pretending to shoot at the classroom.""That isn't OK. With everything going on, that's not something to joke about. That's lives in someone's hands," Hinton said.The principal said he didn't think the student was serious but will not tolerate this behavior in school, so he suspended him.It's an action Sherman said he agrees with for the safety of the students."It's better to be preventative than wait and let it go on, and God forbid something else occur," he said.The principal of Island Park High School, Arthur Nauss, sent WFTX this statement:"I took the disciplinary action of sending the student home after I observed him pointing his finger at another student imitating that he was shooting a gun. The student pointing the finger and the student he was pointing at know each one another and were laughing at one another. There was no threat being issued but I believe it necessary to make it clear to the student, and all our students, that this is unacceptable behavior considering the recent events here in Florida. I called the student’s mother to inform her of what had occurred and let her know I would be working with the student in the future to ensure this behavior does not reoccur.When the student returns to school he will be informed that any future actions such as this one will result in a suspension or expulsion from school. I will also let him know that actions like this in the future will be reported to the appropriate authorities." 2379
