CDC Science Clips: Volume 5, Issue 16, April 22, 2013

 

Attention to past and possible future pandemics leads off this week's Science Clips features. XM Davis and colleagues review data from travelers who "imported" H1n1pdm09 influenza virus, concluding that detection of such importations was a reliable indicator of sustained transmission within the country where the traveler was exposed. In a study led by DA Harnish, a properly fitted NIOSH certified filtering facepiece respirator appears to reduce airborne exposure to H1N1 influenza virus. Bringing concerns up to the present, a New England Journal of Medicine commentary by TM Uyeki and NJ Cox summarizes the emergence of influenza A (H7N9) infections in China.

In-depth investigations of recent and ongoing outbreaks and epidemics also feature prominently this week. A trio of CDC researchers led by SD Bennett describes foodborne outbreaks caused by toxin-producing enteropathogens from 1998 through 2008; the authors note the very frequent occurrence of errors in food handling. A more clinically focused investigation lead authored by SD Holmberg finds that an index of serum markers of liver fibrosis can be used to differentiate stages of chronic hepatitis C virus infection. A multidisciplinary investigation of Puerto Rico's recent epidemic of Dengue by TM Sharp et al finds differences in rates of infection by Dengue virus type and age, emphasizing the need for enhanced primary prevention strategies.

Chronic disease prevention and control requires up to date data and innovative policies. One important data source, the National Report on Biochemical Indicators of Diet and Nutrition in the U.S. Population, is featured in the article by CM Pfeiffer and colleagues. A Slonim et al, writing in the CDC journal Preventing Chronic Disease, summarize expert informant interviews on strategies to increase preventive service use among older adults.

Important data focused on vulnerable population groups at different ends of the age spectrum rounds out the featured articles for this week. Data from the National Center for Health Statistics highlights declines in United States infant mortality from 2005-2011. EL Petsonk, writing with non-CDC colleagues in an article focused on coal mine dust lung disease, reminds us that coal miners remain at risk from occupational exposures.
