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 ...
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]
Rabies is a viral disease that causes encephalitis in humans and other mammals. [ 1 ] It was historically referred to as hydrophobia ("fear of water") due to the symptom of panic when presented with liquids to drink. Early symptoms can include fever and abnormal sensations at the site of exposure. [ 1 ]
Turbot reddish body iridovirus. Megalocytivirus is a genus of viruses in the family Iridoviridae [ 1] and one of three genera within this family which infect teleost fishes, along with Lymphocystivirus and Ranavirus. [ 2] Megalocytiviruses are an emerging group of closely related dsDNA viruses which cause systemic infections in a wide variety ...
Natural reservoir. In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival.
Viruses are by far the most abundant biological entities on Earth and they outnumber all the others put together. [ 89 ] They infect all types of cellular life including animals, plants, bacteria and fungi. [ 6 ]: 49 Different types of viruses can infect only a limited range of hosts and many are species-specific.
Water for injection is water of extra high quality without significant contamination. [1] A sterile version is used for making solutions that will be given by injection. [2] Before such use other substances generally must be added to make the solution isotonic. [3] Isotonic solutions containing water for injection can be given by injection into ...
Portable water purification devices are self-contained, easily transported units used to purify water from untreated sources (such as rivers, lakes, and wells) for drinking purposes. Their main function is to eliminate pathogens, and often also of suspended solids and some unpalatable or toxic compounds. These units provide an autonomous supply ...
