Obesity increases susceptible and mortality to H1N1 virus.
In the 2009 H1N1 pandemic medical science recognized that obesity increased the risk of contracting the virus. Tests on vaccinated obese individuals showed immunecell function at only 70% compared to normal weight individuals. Death rates in obese and morbidly obese H1N1 patients were 3 and 7.6 times the rate of normal weight patients. Research in obese mice showed a 25% mortality rate compared to zero in lean mice with similar immune deficiencies as found in humans.
Frequently I find something in the literature that is absolutely fascinating. It often has to do with health related research and the way it is visualized and communicated. Today, I want to share with you just such results!
In recent months we have been deluged with news about the H1N1 influenza pandemic. You may have wondered, did it really start in Mexico, and how did it spread globally so quickly? Flu viruses continually mutate as they multiply. By analyzing these mutations, scientists can develop a family tree and model how and when the disease spreads!
World now at the start of 2009 influenza pandemic--first one since 1968.
Last Thursday, June 11, the World Health Organization declared the new influenza A H1N1 (formerly known as swine flu) a pandemic. This novel virus strain has not previously circulated in the human population. Although declared as "moderate", the speed at which it has spread, and the potential for a much more virulent form to develop spurred this declaration. No restrictions on travel or border closures have been declared.
