Water-borne diseases are illnesses caused by ingesting water contaminated with human or animal waste containing pathogens. They are a major global public health issue, causing over 2 million deaths annually, especially among children in developing countries. Improving access to clean water and sanitation could reduce the global disease burden by an estimated 4%. Common water-borne diseases are caused by bacteria, viruses, protozoa and parasites transmitted via contaminated water sources.

2.  Water-borne diseases are any illness caused by drinking water
contaminated by human or animal faeces, which contain
pathogenic microorganisms. commonly are transmitted in
contaminated fresh water.
 Infection commonly results during bathing, washing, drinking,
in the preparation of food, or the consumption of Food.
 Waterborne infections are caused by ingestion, airborne or
contact with contaminated water by a variety of infectious
agents which includes bacteria, viruses, protozoa and
helminthes.

3.  It is estimated to cause more than 2.2 million
deaths pear year and higher cases of illness every
day, including diarrhea, gastrointestinal diseases
and systematic illnesses.
 About 1.4 millions of these deaths are children .
 It is suggested that waterborne diseases have an
economic cost associated of 1 billion dollars
annually only in the United state and Worldwide,
an economic loss of nearly 12 billion US dollars per
year is estimated .
 About 780 million people do not have access to a
purified water source, and an estimated 2.5 billion
people lack access to improved sanitation
worldwide.

4.  3.2% of deaths globally are attributable to unsafe water
caused by poor sanitation and hygiene .
 The World Health Organization has reported that
improving water quality can reduce the global disease
burden by approximately 4%.
 Various forms of waterborne diarrheal disease probably
are the most prominent examples, and affect mainly
children in developing countries; according to the World
Health Organization, such diseases account for an
estimated 4.1% of the total daily global burden of disease

7.  Water-borne diseases spread by
contaminating drinking water systems with
feces and urine of infected animals or people.
 sources of water may be contaminated by
infected animals or people. Runoff from:
 Flood water
 Landfills
 Sewer pipes
 Septic fields
 Industrial or residential developments.

8.  To improve the people’s hygienic behaviour .
 To provide them with certain basic needs:
drinking water, washing and bathing facilities
and sanitation. Malaria transmission is
facilitated when large numbers of people sleep
outdoors during hot weather, or sleep in houses
that have no protection against invading
mosquitoes.

10.  Motile,Rod-shaped, flagellate, facultative aerobic, Gram-
negative bacterium.
 A number of its serovars are serious human pathogens.
 Domain:Bacteria
 Kingdom:Eubacteria
 Phylum:Proteobacteria
 Class:Gammaproteobacteria
 Order:Enterobacteriales
 Family:Enterobacteriaceae
 Genus:Salmonella
 Originally isolated in 1880 by Karl J. Erberth
 Currently, 107 strains of this organism have been isolated, many
containing varying metabolic characteristics, levels of virulence, and
multi-drug resistance genes that complicate treatment in areas that
resistance is prevalent.
 Diagnostic identification can be attained by growth on MacConkey and
EMB agars, and the bacteria is strictly non-lactose fermenting.
