Centers for Disease Control and Prevention (CDC). (16 Oct 2017). Waterborne Disease & Outbreak Surveillance Reports.

Description of outbreak

        The outbreak is about the WBDOSS “Waterborne Disease and Outbreak Surveillance System” collect the data on the waterborne disease then outbreaks connected by the recreational water, environmental and the drinking water along with the undetermined exposure to water. The Surveillance program of WBDO is conducted to;

Characterize the etiology as well as epidemiology of the WBDOS along with to identify the important pathogen of waterborne and the deficiencies of the water system.

Improve the investigation and the detection capabilities

Collaborate with federal, local ,and the international agencies on the initiatives (Craun & al, 2006)

        The outbreak report is evaluated by CDC (Centers for Disease Control) and EPA Environmental Protection Agency to determine the epidemiologic evidence which is sufficient and it’s implicate to water as the probable sources of illness. However this outbreak is limited for the environmental data and it includes in the surveillances database but the outbreak has lack of necessary epidemiologic data.

Description of pathogen

        In the distributions system of the outbreak the most common and identified pathogen is the Giardia. The distribution systems which are the vulnerable for the animal and the human facts and the contamination might be the becoming risk of the common and the identified emerging waterborne pathogens. Due to the different pathogens ‘which is the relatively resistant and the residual disinfectant of the concentration is maintained in the system which is most important to prevent the contaminations for the entering systems. Most of the illness is caused by the Giardia and the bacterial pathogens (CRAUN, 2001)

Potential sources

        Drinking water is the potential sources which is used to exposure the pathways of with pathogens that is also absorbed these pathogens. The distribution systems is connected with the WBDOS and tended to the small contamination which is usually affects the portion of the distribution system limiting the potential sources to exposure the pathways of the pathogen. The resulted of this outbreak is associated with the WBDOS has the more than the 1000 illness by the largest causing of the 5000 illness. However the chemical etiology is found the 35% of the WBOD and the system of distribution is caused through the bacterial 17% of the protozoon, and the 14% of Viral, and the undermined pathogen is 30%. (Craun & al, 2006)

Disease investigation principles

        For the investigation of the disease the principle which is used to encompass the collection and the analysis of the water sample for the pathogenic microgormnaism. There are the two principles like the culture dependent methods, and the molecular methods , whereas the culture dependent methods is used for the pathogens of the detection of water and these methods are limited though the low sensitivity and the excessive time of the reliable results (Ramírez-Castillo & al, 2015).
