Mumps
Mumps is considered most contagious in the five days after the onset of symptoms, and isolation is recommended during this period. In someone who has been admitted to the hospital, standard and droplet precautions are needed. People who work in healthcare cannot work for five days.
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.
