New Orleans Repeats Mistakes as It Rebuilds

Many Houses Built in Areas Katrina Flooded Are Not on Raised Foundations By Peter Whoriskey, Washington Post Staff Writer. Thursday, January 4, 2007; Page A01

"It's terrifying: We're doing the same things we have in the past but expecting different results," said Robert G. Bea, a professor of civil engineering at the University of California at Berkeley and a former New Orleans resident who served as a member of the National Science Foundation panel that studied the city's levees.

Unlike many homes being rebuilt in the New Orleans area, this one is being put on a raised foundation. (By Ellis Lucia -- Timespicayune)

Magnitude of International Mobility Annually: • 802 million international arrivals (2006) • 200 million permanent residents outside of their country of birth • 32.9 million persons of concern (UNHCR) • 50,000 smuggled and trafficked persons • 15,000 unaccompanied/separated children Migration Health Consultants Inc. / McMaster University

What is the evidence? •

The contribution to climate change by greenhouse gases generated by fossil fuels and other human made gases – with a component of transportation (of goods and people by conveyances).



The extension of the boundaries of infectious disease zones by contiguous extension of ecological zones supporting vector or nonvector transmission of infectious diseases.

. . . Will not be addressed. Migration Health Consultants Inc. / McMaster University

16

What is the evidence - 1? 1. The establishment of new zones of endemic

infectious diseases, or the “skip” pattern of diseases, introduced by mobile populations or importation of goods. 2. The precipitous and forced movement of people due to extreme and sudden weather events that result in new ecological niches that support infectious diseases.

Migration Health Consultants Inc. / McMaster University

17

What is the evidence - 2? 3. The slowly evolving ecological impacts of environmental change that either force or attract population movement and the classical determinants of health. 4. The temporary movement of populations from low prevalence to higher infectious disease prevalence zones for humanitarian, business or recreational purposes.

FDA lifts 2-week-old ban on most spinach after outbreak Only specific brands will now carry warning Lisa Leff, The Associated Press October 1, 2006

The recent outbreak is the 20th connected to leafy green vegetables - lettuce or spinach - since 1995, half of them linked to farms in central California's Salinas Valley. Investigators don't yet know how the greens linked to the current outbreak became tainted, and may never know for sure, Acheson said. Migration Health Consultants Inc. / McMaster University

Peanut Butter Brand Is Recalled In China 10:52 AM, February 26th 2007

Inspectors in Beijing are recalling peanut butter imported from the United States that may be contaminated with salmonella. The state-run news agency Xinhua reported on the recall of 156 cases of "Peter Pan" and "Great Value" peanut butter. China's Ministry of Health was reportedly notified by the World Health Organization about the possibility of contamination. Migration Health Consultants Inc. / McMaster University

Water, food ... and then strippers 'There must be, like, 750,000 men in town . . . How can I not make money?‘ Rosie Dimanno. New Orleans. Oct. 2, 2005. 08:20 AM

So critical is the carnal business to the city's economy that even Mayor Ray Nagin dropped by a strip joint the other day, to see how things were shakin' (though he didn't go inside). The bacchanalia of the Big Easy is . . . why more than a few would like to see the whole metropolis re- invented, sanitized.

The temporary movement of populations from low prevalence to higher infectious disease prevalence Examples: Predominately “sun destinations”/high prevalence • Malaria: risk in sub-Saharan Africa • Leptospirosis – Eco-tourism, Asia • STI’s/MDR: everywhere • Skin infections: leishmanisis, ARO Migration Health Consultants Inc. / McMaster University

By NEIL SYSON JULIE MOULT and NICK PARKER September 14, 2006 AIDS timebomb Everson Banda lured women for sex sessions at his holiday campsite caravan. The African asylum seeker — who was in Britain illegally and nicknamed himself Ace — bedded scores of women trippers and 13 co-workers in three seasons at the resort.

Cargo plane crashes in Winnipeg, killing pilot Fri. Oct. 7 2005 6:35 AM ET CTV.ca News Staff

Although a Federal Express plane that crashed in Winnipeg Thursday was carrying potentially dangerous viruses. But this is the second accident involving potentially dangerous viruses in less than a year. In March a FedEx van carrying Ebola, hepatitis and tuberculosis was side-swiped in traffic.

The Cessna 208 was flying from Winnipeg to Thunder Bay, Ont., when it went down.
