Paragraph: Nigeria has reported 317 confirmed cases in two months, more than the total for all of last year. The World Health Organization says there are 20 suspected cases across the border in Benin. Nigeria has reported 72 deaths so far. There is no vaccine for the hemorrhagic fever, which is transmitted through the bodily fluids of sick people. Humans also can contract the disease by coming into contact with food contaminated by rat excrement. Those with the disease initially present with high fever but in extreme cases can later suffer bleeding from the nose and mouth. Claim: Nigeria reports record high Lassa fever cases with 317.
Health authorities say a Lassa fever outbreak in Nigeria has reached a record high and there are suspected cases in neighboring Benin as well.

Paragraph: Homebred beef cattle are seen at a local cattle market in Hongseong, about 170 km (106 miles) south of Seoul July 29, 2008. A rare genetic mutation may underlie some cases of mad cow disease in cattle and its discovery may help shed light on where the epidemic started, U.S. researchers reported on Friday. REUTERS/Lee Jae-Won The mutation, in an Alabama cow that tested positive in 2006 for bovine spongiform encephalopathy, or BSE, is identical to one that causes a related brain-wasting disease in humans. This suggests BSE may sometimes arise spontaneously in cattle. Jurgen Richt of Kansas State University said cattle producers must never let down their guard against BSE because cattle anywhere, at any time, can develop the disease. The finding may support a 2005 theory that the BSE epidemic in cattle could be traced to feed contaminated with cattle remains from India, the researchers report in the Public Library of Science journal PLoS Pathogens. BSE or mad cow disease swept through British dairy herds in the 1980s, forcing the destruction of millions of animals. No one ever found where it came from but most experts thought at the time it came from cattle feed that contained the remains of sheep infected with a similar disease called scrapie. Cattle were never known to develop BSE before the epidemic, but some experts have argued they may have. This report lends credence to that idea. BSE, scrapie and a human version called Creutzfeldt-Jakob disease, or CJD, are brain-destroying illnesses called transmissible spongiform encephalopathies. In some cases, animals or people that eat brain and nervous system material from victims of these diseases can develop them, too. They are passed along by misfolded infectious protein fragments called prions. A very rare disease called variant CJD has been found in people who ate infected beef products. Fatal and incurable, it has affected just 167 people so far. Most countries now ban the use of meat and other parts from mammals in food for cattle. They also ban the use of potentially infectious tissues such as brain and spinal cord in human food. "There are tendencies around the world, now that the feed-borne epidemic has gone down, to relax these rules and regulations," Richt said in a telephone interview. "So if we have these genetic cases popping up here and there and we don't have our mitigations in place, we will have another epidemic somewhere." He suggested breeding the gene out of cattle. "We can clean the world cattle herd of that mutation," Richt said. CJD is also known to pop up spontaneously in the human population. A genetic mutation causes the disease in one in a million people globally. Richt and colleagues tested the brain of the Alabama cow and found a mutation identical to the prion gene mutation that causes some cases of CJD. It is probably rare in cattle, found in fewer than one in 2,000, they said in the report, published here But the animal passed along its mutation to its heifer, which suggests it is inherited. Claim: Gene mutation underlies some mad cow disease: study.
A rare genetic mutation may underlie some cases of mad cow disease in cattle and its discovery may help shed light on where the epidemic started, U.S. researchers reported on Friday.

Paragraph: Not a word about costs difficult to comprehend given the estimates the New York Times provided of $120,000 per course of treatment for one and "at least tens of thousands" per year for another. Is this not an issue worthy of a line? Adequate explanation of the benefits reported in both studies. Not a single word about potential harms, as opposed to a New York Times story, which described variously for the two drugs: Again, is this not worthy of at least a line? Adequate explanation of the evidence. Interestingly, both this story and the one from Reuters provided information from the ASCO meetings and neglected to tell readers that both studies have been published in a peer reviewed journal. The NY Times provided both sources. No disease-mongering of melanoma. Two independent experts were quoted. Adequate job reporting the comparisons seen in the trials of the two drugs. The story makes it clear that vemurafenib is experimental and Yervoy is commercially available. Unfortunately, the story includes a prediction from the ASCO President and others that , "vemurafenib will almost certainly get FDA approval this year." While this may occur, it is not certain. And a little shoe leather journalism would easily find someone who would remind readers that FDA approval is not a fait accompli. Because of this, we judge this unsatisfactory. The relative novelty of the two drugs was established. It's clear the story did not rely on a news release. Claim: Two new drugs extend survival for melanoma patients
More broadly, the story contained none of the restrained context provided by the Times. Read and compare. Stories about cancer perhaps especially melanoma because of its treatment challenges should balance promise with realistic context. This story fell short in comparison with the competing New York Times story.
