Rubulavirus
If not vaccinated against mumps, susceptible individuals catch the disease by breathing around an infected person who has coughed or sneezed, releasing their contaminated saliva. Those who have had mumps are usually immune to future infections of the disease. Children have the highest risk of catching mumps, and it is rare for an adult to contract mumps. The incubation period for mumps can range from a couple weeks to a month, while the illness period is a few weeks. The swelling of the salivary glands is caused when the virus travels from the respiratory tract to the salivary glands and multiplies within the glands, causing the glands to swell.

Dorey has written that "passing through a measles infection is sometimes required, for whatever reason, to strengthen some part of a person's vital force", and that diseases such as measles, mumps, rubella and chicken pox are benign conditions that do not kill children in industrialized countries. During a studio debate on Channel 7's "Sunday Night" current affairs program covering the death of a four-week-old baby from whooping cough, Dorey claimed that no one ever dies from the disease, and described her own children's case of the disease as a "storm in a teacup" that was easily handled with natural remedies. The NSW Health Care Complaints Commission criticised the AVN's position, saying that it "ignores the risks of exposure to, and the adverse effects of childhood illnesses". Independent data shows that measles causes the most vaccine-preventable deaths of any disease. It resulted in about 96,000 deaths in 2013. Before immunization in the United States between three and four million cases occurred each year, and the fatality rate is approximately 0.2% of those infected. Most of those who are infected and who die are less than five years old.
