What is WBDOSS public health?

WBDOSS and the public health community work together to look into the causes of contaminated water leading to waterborne disease outbreaks and maintaining those outbreaks. They do so by having the public health community investigating the outbreaks and WBDOSS receiving the reports.

What is WBDOSS reporting?

WBDOSS relies on complete and accurate data from public health departments in individual states, territories, and other U.S. jurisdictions regarding waterborne disease and outbreak activity. In 2009, reporting to the WBDOSS transitioned from a paper form to the electronic National Outbreak Reporting System (NORS).

What is the WBDOSS system?

The Waterborne Disease and Outbreak Surveillance System ( WBDOSS) is the principal database used to identify the causative agents, deficiencies, water systems, and sources associated with waterborne disease and outbreaks in the United States. Since 1971, the Centers for Disease Control and Prevention (CDC), the Council of State and Territorial Epidemiologists (CSTE), and the US Environmental Protection Agency (EPA) have maintained this surveillance system for collecting and reporting data on "waterborne disease and outbreaks associated with recreational water, drinking water, environmental, and undetermined exposures to water." "Data from WBDOSS have supported EPA efforts to develop drinking water regulations and have provided guidance for CDC’s recreational water activities."

How does poverty affect waterborne diseases?

Poverty also increases the risk of communities to be affected by waterborne diseases. For example, the economic level of a community impacts their ability to have access to filtered water. There are South Asian communities that do not have the economic stability to provide clean water and sewage. Lower income correlates to families spending less money on water supply. Socio-economics correlates to less education, which correlates to less knowledge on waterborne diseases. Less developed areas such as Saggian do not have an existing or sufficient pipe to supply water or sewerage system. Less developed countries might be more at risk for potential outbreaks of waterborne diseases but more developed regions also are at risk to waterborne disease outbreaks. Water supply coming from private owned water supplies has a higher probability of a disease such as gastroenteritis spreading than a public (government regulated) water supply.

Perhaps the primary cause of the disease is due to infectious agents. Some of the infections include: E.coli. Giardiases. Cryptosporidiosis. Shigellosis. Naegleria . Amebic meningoencephalitis.

Why is the dispersion of chemical contaminants in the oceans at risk?

The dispersion of chemical contaminants in the ocean water can also cause the outbreak of water related disease due to the release of harmful toxins and chemicals in the water bodies that gets locked in the ice and spread across the coastal areas.

Viruses

Viruses are infectious agents that are very diverse in shape, structure, and behavior, and can only replicate themselves when inside the cell of an organism. Once a cell’s nucleus becomes infected with a virus, that infected cell then reproduces identical copies of itself at an alarming rate, with the ultimate goal of taking over the entire system.

Bacteria

A bacterium, singular for bacteria, is a single-celled organism that lives as part of a colony whose numbers can reach into the billions. They are found in almost every environment on earth and can withstand a wide range of conditions and temperatures. Bacteria aren't necessarily harmful to the human system.

Conclusion

Waterborne pathogens are everywhere but it is up to us to ensure we take the proper precautions to reduce the risk of exposure.

How many nosocomial infections are there in the US annually?

Hospital-acquired infections result from the exposure of debilitated patients to the drug-altered environment of the hospital, where indwelling urinary catheters, intravenous lines, and endotracheal tubes enter normally sterile body sites and allow microbes to penetrate and multiply. Over 2 million nosocomial infections occur in the U.S. annually. Antibiotic-resistant organisms such as Enterobacter spp., Pseudomonas spp., staphylococci, enterococci, Clostridium difficile, and fungi often are responsible for the infectious outbreaks that result. Standard precautions and infection control procedures limit the incidence of nosocomial infections.

How is CMV transmitted?

CMV is transmitted from person to person by sexual activity, during pregnancy or delivery, during organ transplantation, or by contaminated secretions; rarely, (5%) blood transfusions contain latent CMV. Health care workers caring for infected newborns or immunosuppressed patients are at no greater risk for acquiring CMV infection than are those who care for other groups of patients (approx. 3%). Pregnant women and all health care workers should strictly adhere to standard infection control precautions.

What is bloodborne infection?

An infection transmitted through contact with the blood (cells, serum, or plasma) of an infected individual . The contact may occur sexually, through injection, or via a medical or dental procedure in which a blood-contaminated instrument is inadvertently used after inadequate sterilization. Examples of blood-borne infections include hepatitis B and C and AIDS.

What is the best treatment for retinitis?

Antiviral agents such as ganciclovir and foscarnet are used to treat retinitis, colitis, and pneumonitis in immunosuppressed patients; chronic antiviral therapy has been used to suppress CMV, but this protocol has not been effective in preventing recurrence of CMV or development of meningoencephalitis. Ganciclovir has limited effect in congenital CMV. No vaccine is available.

What is an infectious disease?

A disease caused by microorganisms, esp. those that release toxins or invade body tissues. Worldwide, infectious diseases such as malaria, tuberculosis, hepatitis viruses, and diarrheal illnesses produce more disability and death than any other cause. Infection differs from colonization of the body by microorganisms in that during colonization, microbes reside harmlessly in the body or perform useful functions for it, e.g., bacteria in the gut that produce vitamin K. By contrast, infectious illnesses typically cause bodily harm.

What is the process of invasion and multiplication of microorganisms in body tissues?

invasion and multiplication of microorganisms in body tissues, as in an infectious disease. The infectious process is similar to a circular chain with each link representing one of the factors involved in the process. An infectious disease occurs only if each link is present and in proper sequence. These links are (1) the causative agent, which must be of sufficient number and virulence to destroy normal tissue; (2) reservoirs in which the organism can thrive and reproduce; for example, body tissues and the wastes of humans, animals, and insects, and contaminated food and water; (3) a portal through which the pathogen can leave the host, such as the respiratory tract or intestinal tract; (4) a mode of transfer, such as the hands, air currents, vectors, fomites, or other means by which the pathogens can be moved from one place or person to another; and (5) a portal of entry through which the pathogens can enter the body of (6) a susceptible host. Open wounds and the respiratory, intestinal, and reproductive tracts are examples of portals of entry. The host must be susceptible to the disease, not having any immunity to it, or lacking adequate resistance to overcome the invasion by the pathogens. The body responds to the invasion of causative organisms by the formation of antibodies and by a series of physiologic changes known as inflammation.

What are the body's defenses against infection?

These defenses include chemicals, e.g., lysozymes in tears, fatty acids in skin, gastric acid, and pancreatic enzymes in the bowel; mucus that traps the organism; clusters of antibody-producing B lymphocytes, e.g., tonsils, Peyer's patches; and bacteria and fungi (normal flora) on the skin and mucosal surfaces that destroy more dangerous organisms. In patients receiving immunosuppressive drug therapy, the normal flora can become the source of opportunistic infections. Also, one organism can impair external defenses and permit another to enter; e.g., viruses can enhance bacterial invasion by damaging respiratory tract mucosa.
