The WHO on Thursday “announced the deaths of two men from H5N1 avian influenza, one from Egypt and another from China whose death was reported earlier in the media,” CIDRAP News reports. Both men are suspected to have contracted the virus from avian sources, although an investigation into the man from China’s exposure to the virus is ongoing, according to news service. “The two infections and deaths push the WHO global H5N1 count to 576 cases and 339 deaths. According to WHO records, the number of H5N1 cases and deaths reported in 2011 so far are modestly higher than 2010 (60 cases versus 48, and 33 deaths versus 24),” CIDRAP writes (Schnirring, 1/5).
Pneumonia & Flu
Author Laurie Garrett, senior fellow for global health at the Council on Foreign Relations, writes in this Foreign Policy opinion piece that the announcement that researchers from Norway and the U.S. have developed a supercontagious variety of bird flu “has highlighted a dilemma: How do you balance the universal mandate for scientific openness against the fear that terrorists or rogue states might follow the researchers’ work — using it as catastrophic cookbooks for global influenza contagion?” She continues, “Along with several older studies that are now garnering fresh attention, [the research] has revealed that the political world is completely unprepared for the synthetic-biology revolution” and notes “there are no consistent, internationally agreed-upon regulations governing synthetic biology, the extraordinarily popular and fruitful 21st-century field of genetic manipulation of microorganisms.”
Research into transmissible bird flu strains remains “urgent” despite flu investigators’ recent declaration of a “60-day moratorium on avian flu transmission because of the current controversy,” Yoshihiro Kawaoka of Tokyo University and the University of Wisconsin-Madison, “a lead researcher on one of two recent studies showing how H5N1 can be transmitted through airborne droplets” among ferrets, writes in a commentary published Wednesday in the journal Nature, Reuters reports. In December, the U.S. National Science Advisory Board for Biosecurity “asked two leading journals, Nature and Science, to withhold details of both studies for fear it could be used by bioterrorists,” the news agency notes.
The Centers for Disease Control and Prevention (CDC) on Monday released a 268-page annual report that “profiles a wide range of CDC influenza-related projects around the world, from flu surveillance in Indonesia to vaccine effectiveness studies in El Salvador and epidemiology training in Ghana,” CIDRAP News reports. The report also “describes the CDC’s collaborations with the World Health Organization (WHO), outlines projects it supports in about 40 countries, … describes specific studies undertaken in many of those countries,” “lists international training conferences it has sponsored, and describes the CDC program for sharing diagnostic test kits and reagents,” the news service writes. “Over the past six years the [international] program has undergone remarkable growth and has expanded to provide support to over 40 countries, all WHO regional offices and WHO headquarters,” the report notes, according to CIDRAP. “The report, covering 2011, is the third annual account of the agency’s global flu activities, which have expanded greatly in the past decade,” the news service adds (Roos, 10/30).
“As researchers from both sides of the debate over two controversial H5N1 studies weighed in [Tuesday] on full publication versus a more cautionary approach, two U.S. journals” — the Journal of Infectious Diseases (JID) and its sister publication, Clinical Infectious Diseases — “said they are developing policies to address any future such instances,” CIDRAP News writes. “We are developing policies that address these issues on a case-by-case basis, so that freedom of scientific expression can be maintained without sacrificing individual safety or national security,” JID Editor Martin Hirsch wrote in an editorial, the news service notes, adding, “He also introduced three new JID perspective pieces that discuss the difficult issues” (Schnirring, 3/28).
The debate about two studies showing that, with few genetic mutations, H5N1 bird flu strains could become more easily transmissible among ferrets, a laboratory model for humans, “has become a debate about the role of science in society. Two questions should be addressed here: should this type of research be conducted at all; and if so, should all data generated by this research be published?” Ab Osterhaus, head of the Institute of Virology, at Erasmus Medical Centre in Rotterdam, writes in a Guardian opinion piece. A team from Erasmus conducted one of the two studies, he notes.
Rep. Sensenbrenner Sends ‘Fact-Finding Letter’ To White House Science Adviser About Bird Flu Studies
“Representative Jim Sensenbrenner (R-Wis.), a former head of the House committees on science and the judiciary, and currently vice chair of the House Committee on Science, Space, and Technology, last week sent a ‘fact-finding letter’ to White House science adviser John Holdren, asking pointed questions about how the U.S. government has handled the controversy” surrounding two studies that showed how H5N1 bird flu virus could be manipulated to become transmissible among ferrets, a model for humans, “and questioning whether it should have funded the two flu studies,” ScienceInsider reports. “The [Obama] Administration’s response has appeared ad hoc, delayed, and inadequate,” Sensenbrenner writes, adding, “An ad hoc approach is inadequate to balance the priorities of public health and the free flow of academic ideas,” according to the article, which includes the full text of the letter.
The National Science Advisory Board for Biosecurity (NSABB) is scheduled this week to hold “a closed-door meeting to once again look at unpublished manuscripts describing” two studies that showed how H5N1 bird flu virus could be manipulated to become transmissible among ferrets, a model for humans, NPR’s health blog “Shots” reports, noting that the meeting “will include a classified briefing from the intelligence community.” The article examines the “dual use” nature of the studies, meaning “legitimate scientific work that’s intended to advance science or medicine, but that also might be misused with the intent to do harm.” Though the “concept of dual use got a lot of attention even before this bird flu controversy,” scientists, institutions and funding agencies do not always have policies in place to review the potential consequences of research, the blog notes (Greenfieldboyce, 3/26).
“Preventable childhood deaths caused by illnesses such as pneumonia and diarrhea can be nearly eliminated in 10 years,” researchers from the Johns Hopkins Bloomberg School of Public Health and the National Institutes of Health write in a new commentary featured in the June issue of the Journal of the American Medical Association,” a Johns Hopkins press release reports. In the commentary, “researchers outline a strategy and benchmarks for curbing childhood preventable deaths and recommend a new common vision for a global commitment to end all preventable child deaths,” the press release notes (6/14).
The New York Times examines several studies published in the journals Nature and Science looking at how the H5N1 bird flu virus could mutate to become more virulent among humans and outlines the history of controversy surrounding the studies. “While scientists have offered two possible ways in which H5N1 might become a human flu, they’re almost certainly not the only two,” the newspaper writes, adding, “There is no checklist of mutations that any bird flu must acquire to start infecting humans.” According to the newspaper, “Anthony S. Fauci, director of the National Institute of Allergy and Infectious Diseases, hopes scientists will be able to amass a longer list of potential mutations, and even find a common denominator in how they alter H5N1,” which might make it “possible to monitor emerging strains for signs that they are about to cross over into humans” (Zimmer, 6/25).
