(AP) -- Health experts say extraordinary measures against swine flu - most notably quarantines imposed by China, where entire planeloads of passengers were isolated if one traveler had symptoms - have failed to contain the disease. http://www.physorg.com/news177847015.html Medicine & Health Thu, 19 Nov 2009 10:10:01 EST news177847015 Immunity to whooping cough lasts at least 30 years on average, much longer than previously thought, according to a new study by researchers based at the University of Michigan and the University of New Mexico. Details are published October 30 in the open-access journal PLoS Pathogens. http://www.physorg.com/news176067229.html Medicine & Health Thu, 29 Oct 2009 20:34:20 EST news176067229 (PhysOrg.com) -- University of Adelaide researchers have shown they can predict the biggest population peaks of disease-carrying mosquitoes up to two months ahead. http://www.physorg.com/news157107944.html Medicine & Health Tue, 24 Mar 2009 10:09:13 EST news157107944 Researchers at Rhode Island Hospital have completed a study to better understand the impact of infection control measures during a possible flu pandemic. Their study focused on the likelihood of the transmission of flu from individuals showing no symptoms (asymptomatic) or from individuals who are infected but have not yet exhibited symptoms. The researchers call on the scientific community to better understand the transmission of influenza in order to provide guidelines for effective pandemic flu planning. Their findings are published in the March-April 2009 edition of Public Health Reports. http://www.physorg.com/news154192370.html Medicine & Health Wed, 18 Feb 2009 15:13:27 EST news154192370 Researchers from the US Centers for Disease Control and Prevention (CDC) and the Johns Hopkins Bloomberg School of Public Health have found that dengue transmission in Puerto Rico is dependent upon local climate and short-term changes in temperature and precipitation. Details are published February 17 in the open-access journal PLoS Neglected Tropical Diseases. http://www.physorg.com/news154079366.html Medicine & Health Tue, 17 Feb 2009 07:49:59 EST news154079366 "Conventional wisdom - and conventional theory - tells us that when infection can potentially be spread to almost everyone in a community, such as for measles, a disease outbreak can never be contained using voluntary vaccination," says Chris Bauch and Ana Persic, researchers from the University of Guelph. "However, our work shows conventional wisdom may be wrong for diseases that are spread primarily through close contact, such as smallpox." Their findings appear in the open-access journal PLoS Computational Biology on February 6th. http://www.physorg.com/news153145959.html Biology Fri, 06 Feb 2009 12:33:05 EST news153145959 Most successful vaccines and drugs rely on protecting humans or animals by blocking certain bacteria from growing in their systems. But, a new theory actually hopes to take stopping infectious diseases such as West Nile virus and Malaria to the next level by disabling insects from transmitting these viruses. Research to be presented at the 57th American Society of Tropical Medicine and Hygiene (ASTMH) annual meeting in New Orleans, explains how vaccines and drugs may not only be able to stop disease transmission, but also prematurely kill the vectors carrying these diseases; such vectors include ticks, sand flies and mosquitoes - the insects responsible for most deaths world wide. http://www.physorg.com/news147463549.html Medicine & Health Tue, 02 Dec 2008 18:05:49 EST news147463549 Blood transfusions are a valuable treatment mechanism in modern medicine, but can come with the risk of donor disease transmission. Researchers are continually studying the biology of blood products to understand how certain diseases are transmitted in an effort to reduce this risk during blood transfusions. According to a study in sheep prepublished online in Blood, the official journal of the American Society of Hematology, the risk of transmitting bovine spongiform encephalopathy (BSE, commonly known as "mad cow disease") by blood transfusion is surprisingly high. http://www.physorg.com/news139151528.html Medicine & Health Thu, 28 Aug 2008 14:12:08 EST news139151528
