While the rains bring new life and revival, they also bring many waterborne diseases.

At any given time, half of the world's hospital beds are occupied by patients suffering from waterborne diseases.

Millions died of drowning while some died from starvation or from waterborne diseases such as cholera and typhus.

Five to six million people, mostly children, die every year due to waterborne diseases, such as diarrhea, and air pollution.

People who are infected by a waterborne disease are usually confronted with related costs and not seldom with a huge financial burden.

These improvements included chlorination of drinking water, filtration and sewage treatment which led to the decline in deaths caused by infectious waterborne diseases such as cholera and intestinal diseases.

Bioconcentration can also be defined as the process by which a chemical concentration in an aquatic organism exceeds that in water as a result of exposure to a waterborne chemical.

Integration of emergency sanitation measures into disaster preparedness and mitigation policies and plans could help avert epidemics of waterborne diseases when large numbers of people are displaced by disasters or conflicts.

By 9 March 2009 The World Health Organization (WHO) estimated that 4,011 people had succumbed to the waterborne disease since the outbreak began in August 2008, and the total number of cases recorded had reached 89,018.

In every case there's a lot of variation, but something about the environment the people are living in, and I think the only realistic explanation is that it's the degree of waterborne transmission, favored the harmful strains in one place, and mild strains in another.

In that connection, we welcome the proposal by the Government of Germany to hold a third international conference on early warning to discuss aspects of the global early warning system for waterborne meteorological and geological disasters. We call upon countries to actively promote that initiative.

So the task is to try to figure out how to determine whether or not you could get an organism like this to evolve towards mildness by blocking waterborne transmission, thereby allowing the organism only to be transmitted by person to person contact, or person food person contact both of which would really require that people be mobile and fairly healthy for transmission.
