ADDIS ABABA, Nov. 2 (Xinhua) -- Ethiopia will host the 13th World Congress on Public Health (WCPH) in April 2012, the Ethiopian Public Health Association (EPHA) said on Wednesday.The meeting will be held on April 23-27 under the theme: "Moving towards Global Health Equity- Opportunities and Treats".Speaking on the 22nd annual meeting of EPHA held here on Wednesday EPHA President Tewabech Bishaw said about 3,000 participants, including public health students from all over the world are expected to take part in the meeting.He said that preparations are well underway to successfully conduct the meeting.

SAN FRANCISCO, Nov. 29 (Xinhua) -- Hewlett-Packard (HP) on Tuesday issued a statement to refute some security flaw claims on its LaserJet printers."Today there has been sensational and inaccurate reporting regarding a potential security vulnerability with some HP LaserJet printers. No customer has reported unauthorized access. Speculation regarding potential for devices to catch fire due to a firmware change is false," HP said in the statement.Tech blog "The Red Tape Chronicle" reported earlier Tuesday that researchers from Columbia University found that a feature named "remote firmware update" on HP's Internet-connected LaserJet printers could allow hackers take control of the device by installing malicious software, and even manage the printer to catch fire.In the statement, HP said that its LaserJet printers have a hardware element called "thermal breaker" that is designed to prevent a part of the device from overheating or causing a fire, noting that it cannot be overcome by a firmware change as it was reported.The Palo Alto, California-based company said that the specific vulnerability exists for some HP LaserJet printers it placed on a public Internet without a firewall. It conceded that on Apple's Mac computers and PCs running Linux system, it is possible for a specially formatted corrupt print job to trigger a firmware upgrade.The company said that it is building a firmware upgrade to mitigate the issue and suggested consumers could place printers behind a firewall and disable remote firmware upload on exposed printers.Researchers said in the earlier report that they believed the flaw is not limited to HP printers and millions of printers around the world could be vulnerable to hack attacks.

WASHINGTON, Jan. 16 (Xinhua) -- A new study examining weather patterns around the worldwide pandemics of influenza, which caused widespread death and illness in 1918, 1957, 1968 and 2009, finds that each of them was preceded by La Nina conditions in the equatorial Pacific. The study findings are published online Monday in the Proceedings of the National Academy of Science.The study's authors -- Jeffrey Shaman of Columbia University's Mailman School of Public Health and Marc Lipsitch of the Harvard School of Public Health -- note that the La Nina pattern is known to alter the migratory patterns of birds, which are thought to be a primary reservoir of human influenza. The scientists theorize that altered migration patterns promote the development of dangerous new strains of influenza.To examine the relationship between weather patterns and influenza pandemics, the researchers studied records of ocean temperatures in the equatorial Pacific in the fall and winter before the four most recent flu pandemics emerged. They found that all four pandemics were preceded by below-normal sea surface temperatures -- consistent with the La Nina phase of the El Nino- Southern Oscillation.The authors cite other research showing that the La Nina pattern alters the migration, stopover time, fitness and interspecies mixing of migratory birds. These conditions could favor the kind of gene swapping or genetic reassortment that creates novel and therefore potentially more variations of the influenza virus."We know that pandemics arise from dramatic changes in the influenza genome. Our hypothesis is that La Nina sets the stage for these changes by reshuffling the mixing patterns of migratory birds, which are a major reservoir for influenza," says Shaman.Changes in migration not only alter the pattern of contact among bird species, they could also change the ways that birds come into contact with domestic animals like pigs. Gene-swapping between avian and pig influenza viruses was a factor in the 2009 swine flu pandemic.

CANNES, France, Nov. 3 (Xinhua) -- Chinese President Hu Jintao Thursday delivered a speech at the G20 Summit in the French resort city of Cannes. The following is the full text of Hu's speech.Promote Growth Through Win-Win CooperationRemarks by H.E. Hu JintaoPresident of the People's Republic of ChinaAt the Sixth G20 SummitCannes, 3 November 2011President Nicolas Sarkozy,Dear Colleagues,I am glad to come to Cannes to attend the sixth G20 Summit and explore with you ways to counter risks and challenges and promote global development. First of all, I wish to express sincere thanks to you, President Sarkozy, and the French government for the active efforts and thoughtful arrangements you have made for the summit.Currently, the world economic situation needs our high attention. Some major economies are experiencing economic slowdown, and some countries are facing acute sovereign debt problems. Volatility in the international financial markets persists. High inflationary pressure confronts emerging markets. The turbulence in west Asia and north Africa continues. And extreme weather and frequent natural disasters have also exerted negative impact on the world economy. As a result, the global economic recovery is fraught with instability and uncertainty and encounters growing risks and challenges.What has happened since the outbreak of the international financial crisis in 2008 shows that we are facing not just an economic and financial crisis. It is a crisis that has exposed certain deficiencies in the existing institutions and mechanisms, policies and approaches, and ways of development. The world economy is now at a crossroads and global economic governance faces arduous tasks. It is imperative that we stand on a higher plane, transcend differences on specific issues, move beyond short-term considerations, and jointly seek ways to overcome the crisis and sustain development. As the premier forum for international economic cooperation, the G20 must continue to demonstrate the spirit of standing together in times of adversity and pursuing win-win cooperation. At this critical moment, the G20 must work to address the key problems, boost market confidence, defuse risks and meet challenges, and promote global economic growth and financial stability. I wish to make the following proposals in this connection.

ISLAMABAD, Oct. 24 (Xinhua) -- Samina, 38, was shocked when doctor told her that she has been suffering from breast cancer for three years and due to late diagnosis the disease spread into her bones making the chances of survival very slim.Samina said that she is trying hard to fight the disease, at the same time she holds the doctors of her village responsible for failing to diagnose the disease in three long years. She is also concerned about her three kids too young to accept any bitter reality."I can't see the distressed faces of my children, I can't bear the fear that looms in their eyes, they know that with every coming day their mother is moving a step forward to death," Samina told Xinhua in a very low tone.When Samina and all other patients of that gloomy medical ward for breast cancer patients, in Nuclear Medicine Oncology and Radiography (NORI) hospital in Islamabad, were told that October is being observed as breast cancer awareness month they murmured that the awareness message should be reached to every nook and corner of the country this year so that no other woman would die due to unawareness.In a country like Pakistan where one in nine women is prone to breast cancer and around 40,000 women die every year due to lack of awareness of this disease. They come to visit oncology department of hospitals at a stage when the chances of survival are very remote.Omer Aftab, National Coordinator of the Pink Ribbon, said that Pakistan has the highest rate of breast cancer among Asian nations. It is the most common malignancy in women, and accounts for 38.5 percent of all female cancer patients, with 90,000 new cases every year.
