How a person gets infects with the parasites of mumps?

The mumps virus is primarily spread through respiratory droplets, which are produced when an infected person coughs, sneezes, or talks. These droplets can be inhaled by someone who is in close contact with the infected person (within about 6 feet). The virus can also be spread through contact with saliva or mucus from an infected person, such as by sharing drinks or kissing.

Less commonly, the mumps virus can also be spread through contact with contaminated surfaces or objects. The virus can survive on surfaces for several hours, so it is important to wash your hands frequently and avoid touching your face if you are in a public place.

Mumps is most contagious in the days leading up to and following the development of symptoms. However, people who are infected with the virus can be contagious for up to 5 days before they develop symptoms, and for up to 9 days after their symptoms have disappeared.

The incubation period for mumps is typically 12 to 25 days. This means that it can take up to 25 days for someone who has been exposed to the virus to develop symptoms.
