Disease: The Next Big One

BOZEMAN, Montana — Grim prognostications of pestilence are as old as the Book of Revelation, but they have not gone out of style or been rendered moot. Plague is a tribulation that science, technology and social engineering haven’t fixed. In the mid-1960s, some public health officials imagined that antibiotics and other modern therapies would enable us to “close the book” on infectious diseases and so make it possible to focus on noncommunicable afflictions, like heart attack, diabetes and stroke. But that optimism was mistaken...

Extension of the Haiti Cholera Disaster to Mexico

Operational Biosurveillance - biosurveillance.typepad.com - October 1, 2013

Mexico is reporting upwards of 44 cases of cholera now with one fatality involving Hidalgo State and Mexico City.  The appearance of cholera in Mexico City is deeply concerning from the standpoint of the "tip of the iceberg": we only know of the recognized cases.  There are likely others out there.

 

A couple of points about this:

1. Totally expected to see expansion of the Nepalese cholera from Haiti to the DR, to Cuba, and now to Mexico. It is likely to include many other countries in that region before all is said and done.

2. It is likely to spread in Mexico in 'fits and starts' due to lack of indigenous immunity and will cause disruption.

3. It will likely spread along trade and migrant labor routes to the US and other countries doing business with Mexico.

4. Communities in the US may be caught unawareness due to basic expectation of border communities in Texas serving as "canaries in a coal mine" for the rest of the country. We propose the migrant labor routes penetrate deep into the US and far from these border communities.

Smartphone attachment detects viruses and bacteria

theengineer.co.uk - The Engineer - September 18, 2013

Researchers at UCLA have developed a portable smartphone attachment that can be used to perform field testing to detect viruses and bacteria.

This cellphone-based imaging platform could be used for specific and sensitive detection of sub-wavelength objects, including bacteria and viruses and therefore could enable the practice of nanotechnology and biomedical testing in field settings and even in remote and resource-limited environments,’ Aydogan Ozcan, professor of electrical engineering and bioengineering at the UCLA Henry Samueli School of Engineering and Applied Science, said in a statement.

Using this device, which attaches directly to the camera module on a smartphone, Ozcan’s team was able to detect single human cytomegalovirus (HCMV) particles.

The Effect of Exclusive Breastfeeding on Infant Morbidity in Guinea Conakry

Infant morbidity caused by infectious diseases is prevalent in Guinea. However, a study shows that exclusive breastfeeding significantly protected the infants against many of the studied morbidities (OR: 0.28, CI: 0.15-0.51) and specifically against diarrhea (OR: 0.38; 95% CI: 0.17 – 0.86), respiratory infections (OR: 0.27; 95% CI: 0.14 – 0.50), and low growth rate (OR: 0.11; 95% CI: 0.02 – 0.46), but not for otitis, urinary infection, or meningitis. This is to suggest that public health officials should encourage breastfeeding in order to reduce incidence of those diseases.

Dangerous strains of E. coli may linger longer in water

Submitted by Luis Kun

homelandsecuritynewswire.com - June 14th, 2013

A toxin dangerous to humans may help E. coli fend off aquatic predators, enabling strains of E. coli that produce the toxin to survive longer in lake water than benign counterparts, a new study finds.

Researchers from the University at Buffalo and Mercyhurst University reported these results online 7 June in the journal Applied and Environmental Microbiology.

“The take-home lesson is that E. coli that produce Shiga toxin persisted longer in recreational water than E. coli that don’t produce this toxin,” said UB Professor of Biological Sciences Gerald Koudelka, Ph.D., who led the study. “This is because the toxin appears to help E. coli resist predation by bacterial grazers.”

To stop MERS, longer quarantines may be necessary

usatoday.com - May 29th, 2013 - Maria Cheng

A detailed look at two cases of a deadly new respiratory virus called MERS suggests people who have the disease should be isolated for at least 12 days to avoid spreading it, doctors reported Wednesday.

The new germ, a respiratory infection, was first seen in the Middle East and so far has sickened more than 40 people worldwide, killing about half of them.

In the report published online in the journal Lancet, French scientists said the first patient visited Dubai.
