The U.S. population grew by the smallest rate in at least 120 years from 2019 to 2020.Figures released Tuesday by the U.S. Census Bureau show the U.S. population grew by 0.35% from July 2019 to July 2020, an increase of 1.1 million people in a nation with an estimated population of more than 329 million residents.Demographer William Frey says population growth in the U.S. already had been stagnant over the past several years due to immigration restrictions and a dip in fertility.However, the pandemic exacerbated that lethargic-growth trend.Even during the height of the Spanish flu, the growth rate was higher — 0.49%. 632

The World Health Organization is preparing for the "worst case scenario" as it continues to respond to the Ebola outbreak in the Democratic Republic of Congo.Peter Salama, deputy director-general of emergency preparedness and response at the WHO, said in Geneva, Switzerland, on Friday that it's "going to be tough and it's going to be costly to stamp out this outbreak."As of Wednesday, 32 people are suspected to have been infected with Ebola viral disease, including three health care workers. Eighteen of those have died, including one of the health care workers.Of the suspected cases, two have been confirmed as Ebola using laboratory tests, and 10 samples are awaiting results."The number of suspected, probable and confirmed cases is significant, so we are very concerned, and we are planning for all scenarios, including the worst-case scenario," Salama said.Ebola virus disease, which most commonly affects people and nonhuman primates such as monkeys, gorillas and chimpanzees, is caused by one of five Ebola viruses. On average, about 50% of people who become ill with Ebola die.The disease is endemic to the Democratic Republic of Congo, and this is the nation's ninth outbreak since the discovery of the virus in the country in 1976.The latest outbreak is occurring in the Bikoro health zone, 400 kilometers (about 250 miles) from Mbandaka, the capital of Equateur province.Bikoro health zone has a population of about 163,000, with three hospitals and 19 health centers, most with limited functionality, according to WHO.Given the remote location of the outbreak, Salama said, response efforts will be extremely challenging. "It is a dire scene in terms of infrastructure," he said."To give you a sense, we are talking about an area that is 280 kilometers even from the provincial capital of Equateur," he said.The WHO is working with authorities in Congo and is in discussions with the World Food Programme to arrange airlifting supplies to the affected areas. UNICEF is also making doctors available as well as sanitation and hygiene specialists to help contain the outbreak.The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission, either through direct contact with bodily fluids such as blood or secretions or contact with materials that are contaminated with these liquids.Personal protective equipment has been sent to the affected region, and the WHO is planning to have mobile laboratories running by the weekend, after receiving approval from the country's Ministry of Health.Initial control efforts are focusing on tools such as surveillance and monitoring, safe burials and case management.Vaccines along with doctors and epidemiologists are on standby in case they are needed, according to the UN.If they are needed, "WHO is in discussions with the government and, if pertinent, will seek approval from the national regulatory authority and the Ethics Review committee to use vaccines against Ebola as part of the response," spokesman Tarik Jasarevik said.The current vaccine against Ebola is experimental and not a licensed product. Salama pointed out that its use also comes with many challenges, as the vaccine needs to be stored long-term at temperatures between minus 60 to minus 80 degrees Celsius (minus 76 to minus 112 Fahrenheit)."This is not a simple logistical effort; it's not like doing a polio campaign with oral polio vaccines, where we get it immediately out to the field. This is a highly complex sophisticated operation in one of the most difficult terrains on Earth," Salama said.Nine neighboring countries are on high alert, Salama said, but the WHO says the current risk of disease spreading to them is low.West Africa experienced the largest recorded outbreak of Ebola over a two-year period beginning in March 2014; a total of 28,616 confirmed, probable and suspected cases were reported in Guinea, Liberia and Sierra Leone, with 11,310 deaths, according to the WHO.  3999

The U.S. will pay drug company Pfizer .95 billion to produce and deliver 100 million doses of the company's COVID-19 vaccine candidate should the drug prove effective in human trials the company said in a press release on Wednesday.Pfizer will deliver the vaccine if and when the drug receives Emergency Use Authorization from the FDA after a large-scale Phase 3 trial.According to the reports, the deal includes an option for the government to purchase an additional 500 million doses of the vaccine.“Expanding Operation Warp Speed’s diverse portfolio by adding a vaccine from Pfizer and BioNTech increases the odds that we will have a safe, effective vaccine as soon as the end of this year,” Health and Human Services Sec. Alex Azar said in a statement. “Depending on success in clinical trials, today’s agreement will enable the delivery of approximately 100 million doses of this vaccine to the American people.”Pfizer and German firm BioNTech are working together to develop the vaccine.On Monday, Pfizer said in a press release that results from Phases 1 and 2 of a German trial indicated that the drug "could potentially be administered safely, with a manageable tolerability profile," according to data from the tests.Biotech company Moderna is also working to develop a coronavirus vaccine. That candidate will move into Phase 3 testing by the end of the month, and the government has also agreed to purchase and distribute the drug should the large-scale test prove effective. 1497

The view from the airplane window just got a little bit weirder -- or at least it did over Ireland.Several airborne sightings of at least one "very bright" unidentified flying object were seen last Friday, according to air traffic control audio logs.Chatter between airline pilots and Irish air traffic control focused briefly on the sightings, with at least four aviators confirming that they'd seen the phenomenon.The exchange began when one pilot asked Shannon air traffic control if there was nearby military activity. When the air traffic controller replied in the negative, the pilot said that she had seen something moving "so fast.""It came up on our left hand side (rapidly veered) to the north, we saw a bright light and it just disappeared at a very high speed ... we were just wondering. We didn't think it was a likely collision course .. (just wondering) what it could be," she said.A pilot on Virgin Flight 76 added that his flight crew had seen "two bright lights at 11 o'clock (which) seemed to bank over to the right and then climb away at speed." 1073

The University of Iowa ticket office says they are suspending ticket sales for the upcoming football season.In a statement on their ticket website, school officials said that those who renewed their season tickets and paid their per-seat contributions by June 30 would be included in any potential seating plans for Kinnick Stadium.The university also announced that the Hawkeye Express would not operate for the upcoming season because of the potential of reduced capacity.“Hawkeye fans are excited about the upcoming season, and we appreciate their continued enthusiasm and support,” said Henry B. and Patricia B. Tippie, Director of Athletics Chair Gary Barta. “With the current information available, we need to pause additional sales and focus on reduced-capacity seating models based on our season ticket holders. We anticipate finalizing this by late July and will share it with our fans. The option of having the ability to accommodate as many Hawkeye fans who are comfortable attending a game in Kinnick Stadium is still one of the scenarios.”New sales of the digital season pass, mini-plans, and single-game ticket sales were also put on hold. 1161
