Mumps is a contagious viral infection that causes swelling of the salivary glands. It is caused by the mumps virus, an RNA virus of the paramyxovirus family. The virus is transmitted through droplets from the saliva or mucus of an infected person. Common symptoms include fever, headache, muscle aches, and swelling of the salivary glands. While usually self-limiting, complications can sometimes occur affecting organs like the testes, ovaries or brain. The mumps virus is most contagious in the days before and during the onset of swelling.

2. Things to remember
 Respiratory infection
 epidemic parotitis.
 Self limiting
 Not fatal
 Causative organism – mumps virus (RNA virus )
 Transmission – droplet infection

3.  Mumps typically starts with a few days of fever,
headache, muscle aches, tiredness, loss of
appetite, and is followed by painful swelling of
salivary glands.

4. Agent factors
 AGENT :- RNA VIRUS of PARAMYXOVIRUS
family
Genus :- Rubula virus
 Can be grown readily in chick embryo or tissue
culture
 There is only 1 serotype

5.  SOURCE OF INFECTION :- Both clinical and
subclinical (30-40% of all cases)
• Virus can be isolated from the saliva and from swabs
taken from the surface of stenson’s duct
• Also found in blood urine human milk and occasionally in
CSF

6.  PERIOD OF COMMUNICABILITY
• Usually 4 – 6 days before the onset of symptoms
and a week or more there after
• Period of maximum infectivity :- just before and at
the onset of swelling
• No longer infectious after the swelling is subsided

7. Host factors
 Age &sex :- mostly in children of age group 5 – 9 yrs
•More severe in adults than children
• Immunity :- 1 attack , clinical or subclinical is
assumed to induce lifelong immunity
• Most infants below the age of 6 months are
immune because of maternal antibodies

8. Environmental factors
 Endemic disease
 Case occur throughout the year
 Peak incidence is in winter and spring
 Epidemics are often associated with overcrowding

9. Mode of transmission
 Mainly by droplet infection and after direct contact
with the infected persons .
Incubation period
Varies from 2 – 3 weeks , usually 18 days

10. Clinical features
 Pain and swelling in either one or both the parotid
glands
 Sublingual and submandibular glands may also involve
 Earache often present on the affected side prior to the
onset of swelling
 Pain and swelling in the opening of mouth before the
swelling is evident .
 May also affect the testes , pancrease , CNS , ovaries ,
prostrate etc..

11.  In severe cases there may be fever , headache and
other constitutional symptoms which last for 3 – 5
days .
 Swelling subsides slowly over 1 – 2 weeks
