CDC: Man Previously Reported Having MERS Does Not Harbor the Virus
After completing additional and more definitive laboratory tests, the U.S. Centers for Disease Control and Prevention (CDC) has retracted a report made last week that an Illinois man contracted the potentially deadly MERS virus from a patient who was diagnosed with MERS in the United States after spending time as a health care worker in Saudi Arabia. The confusion over the diagnosis came from earlier tests that indicated antibodies to a coronavirus, the class of virus MERS belongs to. However, more definitive tests found that he did not harbor the MERS virus. There are six known versions of the coronavirus; four cause mild illness and two cause the much more serious MERS and SARS viruses. Read more on infectious disease.
Study: 30 Percent of the World’s Population is Obese
A new analysis of global obesity trends finds that approximately 2.1 billion people—or nearly 30 percent of the world population—are obese, according to a new study in The Lancet. Researchers found that rates of being obese or overweight climbed 20 percent in adults and 47 percent in children during the 33 years analyzed. The study, which was funded by the Bill & Melinda Gates Foundation, determined that while obesity was once more common in wealthier nations, approximately two-thirds of the world’s obese population lives in developing countries. In addition, the statistics for the United States were especially troubling; while only 5 percent of the world’s population lives in the United States, the country is home to approximately 13 percent of the world’s obese population.

Study: Lung Cancer Screening Can Scare People into Quitting Smoking
In addition to early detection and treatment of lung cancer, early screening can also scare people into quitting smoking before they even develop the disease, according to a new study in the JNCI: Journal of the National Cancer Institute. Researchers based their findings on an analysis of 14,621 current smokers, 55-70 years old, with a 30 or more pack-year smoking history and who had smoked during the last 15 years. The data was taken from the Lung Screening Study component of the U.S. National Lung Screening Trial. The study found that "...abnormal screening results may present a 'teachable moment'" and that "[f]uture lung cancer screening programs should take advantage of this opportunity to apply effective smoking cessation programs."
