Parotid gland
Mumps is seen to be a common cause of parotid gland swelling - 85% of cases occur in children younger than 15 years. The disease is highly contagious and spreads by airborne droplets from salivary, nasal, and urinary secretions. Symptoms include oedema in the area, trismus as well as otalgia. The lesion tends to begin on one side of the face and eventually becomes bilateral. The transmission of the paramyxovirus is by contact with the infected persons saliva. Initial symptoms tend to be a headache and fever. Mumps is not fatal, however further complications can include swelling of the ovaries or the testes. Diagnosis of mumps is confirmed through viral serology, management of the condition includes hydration and good oral hygiene of the patient requiring excellent motivation. However, since the development of the mumps vaccine, given at the age of between 4–6 years, the incidence of this viral infection has greatly reduced. This vaccine has reduced the incidence by 99%.
Australian Vaccination-risks Network
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.
