The Centers for Disease Control and Prevention said on Tuesday that it is likely that the spread of coronavirus will reach pandemic levels, as scientists still are trying to solve how to stop the spread of the deadly virus. In the meantime, the CDC has offered some tips it believes will help prevent the spread of the disease. Avoid close contact with people who are sick.Avoid touching your eyes, nose, and mouth.Stay home when you are sick.Cover your cough or sneeze with a tissue, then throw the tissue in the trash.Clean and disinfect frequently touched objects and surfaces using a regular household cleaning spray or wipe.Follow CDC’s recommendations for using a facemask.CDC does not recommend that people who are well wear a facemask to protect themselves from respiratory diseases, including COVID-19.Facemasks should be used by people who show symptoms of COVID-19 to help prevent the spread of the disease to others. The use of facemasks is also crucial for 982

The Dow Jones Industrial Average closed down more than 800 points on Tuesday — a day after the Dow dropped more than 1,000 points in the biggest single-day loss of 2020.The Dow finished Tuesday down 878 points, marking the fourth-largest one-day drop in the market's history. Fears about the worldwide spread of COVID-19, better known as coronavirus, have prompted a slowdown in global markets. The CDC compounded fears of the spread of the disease Tuesday when it said that Americans need to prepare for "significant disruptions" to their daily lives."Ultimately we expect we will see community spread in this country," CDC Director of Immunization and Respiratory Diseases Dr. Nancy Messonier. said. "It’s not so much a question of if this will happen anymore, but rather more a question of exactly when this will happen and how many people in this country will have severe illness."The two-day drop has wiped out all year-to-date gains the Dow has made since the new year began.The loss also comes hours after President Donald Trump attempted to assuage fears of a global economic slowdown. Speaking at a press conference in India, Trump claimed that his administration would prevent the spread of the virus. "I think it's going to be under control and it's going to work out fine," Trump said. 1309

The man behind the American pastime of paint-by-numbers pictures died on April 1 at the age of 93, according to his son. Dan Robbins created the first pictures and helped popularize paint-by-numbers kits in the 1950s.Robbins' son, Larry, said his dad was working as a package designer for the Palmer Paint Company in Detroit when he came up with the idea for paint-by-numbers in the late 1940s. He worked there as a graphic artist and sold children's paint that was washable.The idea for paint-by-numbers started when Robbins' boss asked him to come up with an item that could be geared towards adults. Robbins got inspiration for the product from Leonardo da Vinci. The famous artist would hand out numbered designs to apprentices. Robbins took that concept and evolved it into paint-by-numbers.Robbins' work had a significant impact on the pop culture of the 1950s and '60s, since post-World War II Americans found themselves with leisure time to pursue hobbies and activities such as painting."Dad was a very, very modest person. He would never bring up his career. If someone asked him, he'd explain," Larry Robbins said. "Dad was into the accomplishment of providing ... for people like me who can't draw a stick man, to be able to paint and the experiencing of creating a nice piece of art work."Before computers were involved, the artists creating the pictures had to paint the image and then use a piece of acetate or clear plastic over the original to create the areas for each number. Beginner kits started with 20 colors and the number of colors increased with the level of difficulty.Robbins' son said that his father didn't get rich from his invention. Dan Robbins didn't own the company, and eventually his product's parent company, Craft Master, was bought by General Mills.Robbins ended up in the Chicago area and did his own consulting work. He did art work, packaging, and new product development until he retired in the 1980s, according to his son.His work is still on display in the Detroit Historical Museum, along with works from the likes of Henry Ford.Dan Robbins died in Toledo, Ohio, after contracting pneumonia following a series of falls, according to his son. He is survived by his wife, two sons, and several grandchildren and great-grandchildren. 2289

The first participant in a clinical trial for a vaccine to protect against the new coronavirus will receive an experimental dose on Monday, according to a government official.The National Institutes of Health is funding the trial, which is taking place at the Kaiser Permanente Washington Health Research Institute in Seattle. The official who disclosed plans for the first participant spoke on condition of anonymity because the move has not been publicly announced.Public health officials say it will take a year to 18 months to fully validate any potential vaccine. Testing will begin with 45 young, healthy volunteers with different doses of shots co-developed by NIH and Moderna Inc. There’s no chance participants could get infected from the shots, because they don’t contain the virus itself. The goal is purely to check that the vaccines show no worrisome side effects, setting the stage for larger tests.Dozens of research groups around the world are racing to create a vaccine as COVID-19 cases continue to grow. Importantly, they’re pursuing different types of vaccines — shots developed from new technologies that not only are faster to produce than traditional inoculations but might prove more potent. Some researchers even aim for temporary vaccines, such as shots that might guard people’s health a month or two at a time while longer-lasting protection is developed.Also in the works: Inovio Pharmaceuticals aims to begin safety tests of its vaccine candidate next month in a few dozen volunteers at the University of Pennsylvania and a testing center in Kansas City, Missouri, followed by a similar study in China and South Korea.Even if initial safety tests go well, “you’re talking about a year to a year and a half” before any vaccine could be ready for widespread use, according to Dr. Anthony Fauci, director of NIH’s National Institute of Allergy and Infectious Diseases.That still would be a record-setting pace. But manufacturers know the wait — required because it takes additional studies of thousands of people to tell if a vaccine truly protects and does no harm — is hard for a frightened public.President Donald Trump has been pushing for swift action on a vaccine, saying in recent days that the work is “moving along very quickly” and he hopes to see a vaccine “relatively soon.”Today, there are no proven treatments. In China, scientists have been testing a combination of HIV drugs against the new coronavirus, as well as an experimental drug named remdesivir that was in development to fight Ebola. In the U.S., the University of Nebraska Medical Center also began testing remdesivir in some Americans who were found to have COVID-19 after being evacuated from a cruise ship in Japan.For most people, the new coronavirus causes only mild or moderate symptoms, such as fever and cough. For some, especially older adults and people with existing health problems, it can cause more severe illness, including pneumonia. The worldwide outbreak has sickened more than 156,000 people and left more than 5,800 dead. The death toll in the United States is more than 50, while infections neared 3,000 across 49 states and the District of Columbia. The vast majority of people recover. According to the World Health Organization, people with mild illness recover in about two weeks, while those with more severe illness may take three weeks to six weeks to recover.___The Associated Press receives support for health and science coverage from the Howard Hughes Medical Institute’s Department of Science Education.
