How Does BioProtect Protection Work?

The active ingredient in BioProtect polymerizes to all surfaces and is both colorless and odorless.

Think of BioProtect as a layer of electrically charged swords.  When a microorganism comes in contact with the treated surface, the quaternary amine sword punctures the cell membrane and the remnants are then electrocuted.

Since nothing is transferred to the now dead cell, the antimicrobial does not lose it’s strength and the sword is now ready for the next cell to contact it.  (NOTE: Normal cleaning of the treated surfaces is necessary in order for the BioProtect   antimicrobials to continue their effectiveness.  Dirt buildup,  paint, dead microbes, etc. will cover the treatment prohibiting it from killing microorganisms.)

The relationship between entomological indicators of Aedes aegypti abundance and dengue virus infection

The relationship between entomological indicators of Aedes aegypti abundance and dengue virus infection

Abstract

Routine entomological monitoring data are used to quantify the abundance of Aeaegypti. The public health utility of these indicators is based on the assumption that greater mosquito abundance increases the risk of human DENV transmission, and therefore reducing exposure to the vector decreases incidence of infection. Entomological survey data from two longitudinal cohort studies in Iquitos, Peru, linked with 8,153 paired serological samples taken approximately six months apart were analyzed. Indicators of Aeaegypti density were calculated from cross-sectional and longitudinal entomological data collected over a 12-month period for larval, pupal and adult Aeaegypti. Log binomial models were used to estimate risk ratios (RR) to measure the association between Aeaegypti abundance and the six-month risk of DENV seroconversion. RRs estimated using cross-sectional entomological data were compared to RRs estimated using longitudinal data. Higher cross-sectional Aeaegypti densities were not associated with an increased risk of DENV seroconversion. Use of longitudinal entomological data resulted in RRs ranging from 1.01 (95% CI: 1.01, 1.02) to 1.30 (95% CI: 1.17, 1.46) for adult stage density estimates and RRs ranging from 1.21 (95% CI: 1.07, 1.37) to 1.75 (95% CI: 1.23, 2.5) for categorical immature indices. Aeaegypti densities calculated from longitudinal entomological data were associated with DENV seroconversion, whereas those measured cross-sectionally were not. Aeaegypti indicators calculated from cross-sectional surveillance, as is common practice, have limited public health utility in detecting areas or populations at high risk of DENV infection.    Read More...

Flint water crisis likely the cause of deadly Legionnaires outbreak

Flint water crisis likely the cause of deadly Legionnaires outbreak

(CNN)Virginia Tech Professor Marc Edwards released to CNN the unpublished results of a study that show the Flint water crisis most likely caused the deadly outbreak of Legionnaires disease that killed at least 12 people since 2014.

Edwards is the independent Virginia Tech researcher who found lead in Flint's drinking water back in 2015, when state officials still denied it was leeching into the water supply.
The engineering professor says he recreated the crisis in his lab this winter and found that the corrosive water created an environment where bacteria could flourish.   Read More.....

Singapore: First Zika cluster of 2017 discovered in Hougang, fogging begins

Singapore: First Zika cluster of 2017 discovered in Hougang, fogging begins

The confirmation of two locally transmitted cases of the Zika virus at Simon Place, near Kovan in Hougang and the discovery of a cluster have triggered frenzy among people. Though MOH declined to reveal any information about the patients, who fortunately are not pregnant, it has ordered vector control operations in the area.

NEA has released a notice stating that thermal fogging will be carried out. Officers were also seen going from door to door at about 9am informing residents about the fogging. Residents were urged to stay indoors and keep their pets in safe places. They were also asked to cover food properly during the time of fogging.   Read More....

NASA Satellite Identifies Global Ammonia ‘Hotspots’

NASA Satellite Identifies Global Ammonia ‘Hotspots’

Study ties fertilizers, animal waste, changes to atmospheric chemistry and climate change to increased ammonia over the United States, Europe, China and India

 

The first global, long-term satellite study of airborne ammonia gas has revealed “hotspots” of the pollutant over four of the world’s most productive agricultural regions. The results of the study, conducted using data from NASA’s Atmospheric Infrared Sounder (AIRS) instrument on NASA’s Aqua satellite, could inform the development of strategies to control pollution from ammonia and ammonia byproducts in Earth’s agricultural areas.    Read More

Estimation of polio infection prevalence from environmental surveillance data

Estimation of polio infection prevalence from environmental surveillance data

Keeping an eye on polio

As the eyes are a mirror of the soul, a city’s sewage is a reflection of its people’s health. Berchenko et al. take advantage of a natural experiment in southern Israel to quantify this relationship for polio. By measuring virus shed into sewage waste in cities in which a known number of people received a live polio vaccine, the authors created tools that can be used to monitor polio incidence in other cities. Thus, virus levels in sewage waste can give an early warning of the reappearance of viral disease or verify its absence.   Read More....
