Infectious disease. Waterborne diseases are conditions (meaning adverse effects on human health, such as death, disability, illness or disorders) [1]: 47 caused by pathogenic micro-organisms that are transmitted by water. These diseases can be spread while bathing, washing, drinking water, or by eating food exposed to contaminated water. [2]
Major outbreaks. Water virology was born after a large hepatitis outbreak transmitted through water was confirmed in New Delhi between December 1955 and January 1956. [4] Viruses can cause massive human mortality. The smallpox virus killed an estimated 10 to 15 million people per year until 1967. [3] Smallpox was finally eliminated in 1977 by ...
Water stagnation for as little as six days can completely change bacterial community composition and increase cell count. [3] Stagnant water may be classified into the following basic, although overlapping, types: Water body stagnation (stagnation in swamp, lake, lagoon, river, etc.) Surface and ground waters stagnation. Trapped water stagnation.
Cholera. A person with severe dehydration due to cholera, causing sunken eyes and wrinkled hands and skin. Cholera (/ ˈkɒlərə /) is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. [4][3] Symptoms may range from none, to mild, to severe.

Mycobacterium marinum is an acid-fast, aerobic bacterium which can infect humans. [4] Infection is usually associated either with swimming, preparing sea food, or with keeping or working with aquarium fish. [2] Infections of humans are rare due to the chlorination of water. [4] The bacteria penetrate the skin through trauma, usually from bites ...
The bacteria are ubiquitous in fresh water, and cultured fish reared in ponds or raceways are the primary concern – with disease most prevalent in air temperatures above 12–14 °C. Due to the appearance of bacterial clumps, it can be mistaken for a fungal infection. The disease is highly contagious, and the outcome is commonly fatal.
Elizabethkingia meningoseptica (King 1959) Kim et al. 2005. Elizabethkingia meningoseptica is a Gram-negative, rod-shaped bacterium widely distributed in nature (e.g. fresh water, salt water, or soil). It may be normally present in fish and frogs; it may be isolated from chronic infectious states, as in the sputum of cystic fibrosis patients.
Streptococcus shiloi (Eldar, 1994) Streptococcus iniae is a species of Gram-positive, sphere-shaped bacterium belonging to the genus Streptococcus. Since its isolation from an Amazon freshwater dolphin in the 1970s, S. iniae has emerged as a leading fish pathogen in aquaculture operations worldwide, resulting in over US$ 100M in annual losses.
