An American was possibly exposed to Ebola while recently providing medical assistance in Congo, according to a release from the University of Nebraska Medical Center College of Public Health.The person, who has not been identified, is headed to the Nebraska Medical Center in Omaha for monitoring, the release states, adding the Nebraska Medical Center is home to one of the nation's few dedicated biocontainment units."This person may have been exposed to the virus but is not ill and is not contagious," said Ted Cieslak, infectious diseases specialist with Nebraska Medicine and associate professor of epidemiology in the University of Nebraska Medical Center College of Public Health. "Should any symptoms develop, the Nebraska Medicine/UNMC team is among the most qualified in the world to deal with them."The Democratic Republic of Congo is going through one of the deadliest Ebola outbreaks in history. The outbreak began August 1 and has left more than 300 people dead, with 545 confirmed cases recorded as of Saturday, according to the country's health ministry. Another 48 cases are considered probable.The World Health Organization said protests in Congo over election delays and a deteriorating security situation are interfering with their field teams' ability to carry out Ebola vaccinations in some areas. The American, the Nebraska release states, is not an official patient and is being taken privately to the medical center. Federal, state and county public health officials plan to monitor the person in a secure area not accessible by the public or any patients. Monitoring could take as long as two weeks, the release states.No updates will be given on the person's status during the monitoring period unless needed, the release also states. If it is necessary, though, the individual will be transferred to the Nebraska Biocontainment Unit, where regular updates will be provided.This isn't the first time possible Ebola patients were treated at the Nebraska Medical Center. Nebraska Medicine treated three patients with Ebola in 2014. In 2015, five Americans were monitored at the center after being exposed to the virus in West Africa, but none developed the disease. 2234

Airlines in multiple countries have suspended the use of Boeing's new 737 MAX 8 aircraft over concerns about its safety, after an Ethiopian Airlines flight of the same model crashed Sunday killing all 157 on board.Flight ET302 to Nairobi had just taken off from the Ethiopian capital of Addis Ababa Sunday when it reported technical problems and asked for permission to turn back. It crashed shortly afterwards.As the crash investigation got underway, the Civil Aviation Administration of China ordered Monday that all domestic Boeing 737 MAX 8 jets be out of the air by 6 p.m. local time, due to its principle of "zero tolerance for safety hazards."China has one of the world's largest fleets of Boeing 737 MAX 8, operating 97 of the planes, according to Chinese state-run media.The move was followed by an announcement from Ethiopian Airlines that the carrier had grounded its fleet of Boeing 737 MAX 8 jets as an "extra safety precaution." Cayman Airways also said on Monday it was grounding both of its "new Boeing 737 MAX 8 aircraft ... until more information is received."Sunday marked the second time in less than six months that a new Boeing aircraft crashed just minutes into a flight. A Lion Air Boeing 737 MAX 8 flight went down over the Java Sea last October, killing all 189 people on board.Both crashes are under investigation and there is no evidence of a link between the two, but similarities in the incidents have prompted caution among some airlines."Given in both air crashes, the aircrafts were newly delivered Boeing 737 MAX 8, and both accidents occurred during the take-off, they share certain similarities," the Chinese administration said in a statement. It added that it would contact Boeing and the US Federal Aviation Administration to confirm "flight safety" issues before allowing the planes to fly again.Mary Schiavo, a CNN aviation analyst and the former Inspector General of the US Transportation Department, called the two incidents "highly suspicious.""Here we have a brand-new aircraft that's gone down twice in a year. That rings alarm bells in the aviation industry, because that just doesn't happen," she said.State-owned Ethiopian Airlines is one of Africa's leading aviation groups, and the continent's largest carrier by number of passengers.The Kenyan and Ethiopian governments announced a joint disaster response team on Monday to investigate the crash. Kenya's Cabinet Secretary of Transport James Macharia described it as a "very complex investigation."In a statement Sunday, Boeing said it was "deeply saddened" to hear about the loss of life in the Ethiopian Airlines plane crash."A Boeing technical team will be traveling to the crash site to provide technical assistance under the direction of the Ethiopia Accident Investigation Bureau and US National Transportation Safety Board," the statement said.Investigations ongoing after crashThe Ethiopian Airlines flight to Nairobi, in Kenya, lost contact with authorities shortly after takeoff at 8.44 a.m. local time, just minutes after it left Bole International Airport.Tewolde GebreMariam, Ethiopian Airlines CEO, said at a press conference Sunday that the pilot had reported technical difficulties and had been given clearance to return to the Ethiopian capital.An eyewitness told CNN they saw smoke coming from the plane before it crashed on Sunday.GebreMariam said a routine maintenance check hadn't revealed anything before takeoff. The pilot was a senior Ethiopian Airlines employee who had flown more than 8,000 hours and had an "excellent flying record," he added."As it is a fresh incident, we have not been able to determine the cause. As I said, it is a brand new airplane with no technical remarks, flown by a senior pilot and there is no cause that we can attribute at this time," GebreMariam said.Speaking on Monday, Kenyan Transport Secretary Macharia said relatives of the victims would be given "the utmost attention," including accommodation and flights to Ethiopia, if necessary.The US National Transportation Safety Board said on Sunday it would be sending a team of four to assist in the investigation into the crash.CNN aviation expert Richard Quest said while a "final determination" on the cause of the crash might be years away, information from the flight recorders should be retrieved within a matter of weeks.Global disasterCitizens of 35 countries were among the 157 people killed in Sunday's crash, including 32 Kenyans, 18 Canadians, nine Ethiopians and eight passengers each from China, Italy and the United States.The United Nations has announced 19 of their staff members were among the dead, including employees of the World Food Programme, the Office of the High Commissioner on Refugees and the Food and Agriculture Organization.Not all victims have been named, but some details have been released.The Ethiopian government expressed its "deepest condolences to the families," in a statement from the office of Prime Minister Abiy Ahmed. 4985

Americans have welcomed him into their living rooms since 1984, and for decades, the beloved host of Jeopardy became a daily staple in many people’s lives. This week, on the familiar set of the popular game show, Alex Trebek delivered somber news: he was diagnosed with pancreatic cancer. "Just like 50,000 others each year, this week I was diagnosed with stage 4 pancreatic cancer,” Trebek said in the video. “Now, normally the prognosis for this is not very encouraging, but I’m going to fight this, and I’m going to keep working." The sad reality is Trebek is right. Pancreatic cancer is one of the deadliest types of the disease. “The 5-year survival rate is just 9 percent,” says Julie Fleshman with the Pancreatic Cancer Action Network. Fleshman says it’s also not an easy disease to diagnose early, because symptoms like back pain and stomach aches can be benign. Therefore, pancreatic cancer is often only diagnosed when it's reached stage 4, meaning it has spread to other parts of the body. But Fleshman says Trebek's video message may be a breath of fresh air for anyone battling the disease. "I think having hope and empowerment when diagnosed with a difficult disease like pancreatic cancer is extremely important, and Alex’s message yesterday was courageous and inspiring to all of us," she says.In his announcement, Trebek inserted a bit of his trademark humor, saying he was going to fight this because “truth told, I have to, because under the terms of my contract I have to host Jeopardy for three more years!"Trebek asked for prayers from his fans.
