question:
Paragraph: The research was released Monday as the state started its first statewide campaign to prevent the disease. The most recent case came out of Hilo, where a resident contracted the disease in late November. Department of Health officials suspect the Big Island patient accidentally ingested an infected slug while drinking from a garden house. People contract the disease by ingesting food contaminated with snails or slugs that carry parasitic larvae from rat droppings. The state's $300,000 campaign will include a series of television and radio announcements urging people to wash fruits and vegetables before eating them to avoid the potentially debilitating disease, which affects the brain and spinal cord. The Legislature earlier this year granted the Health Department $1 million over the next two years to control the spread of rat lungworm. There were 18 laboratory-confirmed cases in Hawaii this year. The Big Island has seen the most cases at 11, followed by Maui at six. Sue Jarvi, a professor at the University of Hawaii at Hilo, said the recent study shed light on how common the disease is in rats. Jarvi said rats near Hilo Harbor and Hilo International Airport are especially worrisome because some end up getting transported to the mainland and other countries, potentially exporting rat lungworm. The Centers for Disease Control and Prevention, UH-Hilo and researchers in Thailand are all reviewing parasites that were collected, Jarvi said. "The risk of rat lungworm disease is present on all islands and there are basic steps we can take each day to reduce this risk and help prevent infection," said Keith Kawaoka, the department's deputy director of environmental health. "Knowledge is the best defense we can provide people with to collectively protect our communities from rat lungworm disease in Hawaii." Claim: Hawaii launches campaign to prevent spread of rat lungworm.
answer:
Almost 94 percent of rats in the Hilo region are infected with the parasite that causes rat lungworm disease, a recent study on the meningitis-like disease showed.

question:
Paragraph: Although Pfizer continues to test the drug, called dacomitinib, in another Phase III study, hopes for its success have now largely faded, according to ISI Group analyst Mark Schoenebaum. "We believe consensus expectations (for the drug) will be close to zero given today's readout" of unsuccessful trial results, Schoenebaum said in a research note. In one of the failed trials, called ARCHER 1009, patients given Pfizer's once-daily pill did not show improved survival without the cancer worsening, compared with Roche Holding AG's widely used Tarceva (erlotinib). Tarceva is the current standard of care in patients with mutated forms of a protein called Epidermal Growth Factor Receptor (EGFR). The protein plays a role in normal regulation of cell growth, but when mutated is believed to cause cells to proliferate and thereby help spur various types of cancer. Dacomitinib is designed to block several types of Epidermal Growth Factor receptors, while Tarceva and similar treatments for lung cancer target only one type of receptor. Cowen and Co had forecast annual sales of $500 million by 2020 for dacomitinib, if it were approved for lung cancer. That would make it a moderate-sized product for Pfizer, the largest U.S. drugmaker, which has annual revenue of $50 billion. Schoenebaum said there has been little investor interest in the drug and that Wall Street had expected it to generate annual sales of only $300 million by 2018. The second failed trial, named BR.26, involved patients that previously had failed to benefit from chemotherapy as well as from treatment with an EGFR inhibitor. Overall survival of patients taking the Pfizer drug was not prolonged in the study, compared with patients given a placebo. Pfizer said adverse events seen with dacomitinib were consistent with those seen in smaller earlier studies. In the meantime, Pfizer said dacomitinib is also being tested in a third late-stage trial, called ARCHER 1050, among patients with advanced non-small cell lung cancer who have not received prior treatment. The study will compare dacomitinib with Iressa (gefitinib), an EGFR inhibitor sold by AstraZeneca Plc. Results from that study are expected in 2015. Pfizer shares were little changed in morning trading on the New York Stock Exchange. Claim: Pfizer lung cancer drug fails in two large studies.
answer:
Pfizer Inc on Monday said one of its experimental drugs had failed to meet its goals in two late-stage studies among patients who had received prior treatment for advanced non-small cell lung cancer, the most common form of the disease.

question:
Paragraph: Legionnaire's is a flu-like illness contracted when infected water vapor is inhaled. The elderly and people with weakened immune systems can be particularly susceptible. The Illinois Department of Public Health reported 12 cases at Covenant Assisted Living in Batavia through August. The two new cases were reported in recent days. State officials say the retirement home plans to clean its water systems, including cooling towers that release water drops into the air. The agency's director, Dr. Ngozi Ezike, says there could be additional cases, even with corrective measures. Illinois reported over 500 cases of Legionnaires' disease in 2018. Claim: Officials: 2 new cases of Legionnaires' in suburban Chicago.
answer:
Public health officials are worried an outbreak of Legionnaires' disease at a suburban Chicago retirement home appears to be spreading with two new cases in the nearby community.
