Childhood immunizations in the United States
Mumps is a contagious disease caused by the virus by the same name. Since most people in the United States have been vaccinated, mumps is now a rare disease in this country. Currently there are no specific treatments for mumps.
Mumps is spread person to person by droplets of saliva or mucus from the mouth, nose or throat of an infected person. This is done through coughing, sneezing, talking, and coming into contact with contaminate items. Transmission likely occurs before the salivary glands swell an up to 5 days after the swelling begins.
Thrips
Many thrips are pests of commercial crops due to the damage caused by feeding on developing flowers or vegetables, causing discoloration, deformities, and reduced marketability of the crop. Some thrips serve as vectors for plant diseases, such as tospoviruses. Over 20 plant-infecting viruses are known to be transmitted by thrips, but perversely, less than a dozen of the described species are known to vector tospoviruses. These enveloped viruses are considered among some of the most damaging of emerging plant pathogens around the world, with those vector species having an outsized impact on human agriculture. Virus members include the tomato spotted wilt virus and the impatiens necrotic spot viruses. The western flower thrips, "Frankliniella occidentalis", has spread until it now has a worldwide distribution, and is the primary vector of plant diseases caused by tospoviruses. Their small size and predisposition towards enclosed places makes them difficult to detect by phytosanitary inspection, while their eggs, laid inside plant tissue, are well-protected from pesticide sprays. When coupled with the increasing globalization of trade and the growth of greenhouse agriculture, thrips, unsurprisingly, are among the fastest growing group of invasive species in the world. Examples include "F. occidentalis", "Thrips simplex", and "Thrips palmi".
