Brucella include arthritis or epididymo-orchitis, spondylitis, neurobrucellosis, liver abscess formation, and endocarditis, the latter potentially fatal. Human brucellosis is usually not transmitted from human to human; people become infected by contact with fluids from infected animals (sheep, cattle, or pigs) or derived food products, such as unpasteurized milk and cheese. Brucellosis is also considered an occupational disease because of a higher incidence in people working with animals (slaughterhouse cases). People may also be infected by inhalation of contaminated dust or aerosols, and as such, the CDC has labeled "Brucella" species as highly weaponizable. Human and animal brucellosis share the persistence of
Human milk bank bank in the US. The 1960’s saw a decline in milk banking because of recent advances in neonatal care and baby formula. Despite these new advancements, in 1980 the World Health Organization and the United Nations Children’s fund maintained their position that donor breast milk is the best alternative to the mother’s breast milk. The practice of milk banking declined further with the HIV epidemic. The need for stringent screening increased the cost of operating milk banks, forcing them to close doors. Improved screening methods and standardization of procedure have made donated milk a viable alternative to mother’s breast milk.
