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.
Cucumber mosaic virus
CMV is mainly transmitted by aphids. It can also be spread mechanically by humans. However CMV is less stable than viruses like TMV and therefore is not as easily spread by humans. The virus, as spread by aphids, has an acquisition period of five to ten seconds and an inoculation period of about a minute. However after two minutes the probability of inoculation largely decreases and within two hours is no longer able to be spread by that particular vector. This virus is non persistent and is stylet borne. CMV is carried by 60–80 different species of aphids and can also be transmitted by seed.
