one day. On examination, he has a temperature of 100 F. He is having a mild
tender swelling in front of and below left year. Margins of this swelling cannot be
defined.

b. Describe the epidemiology of given disease.

d. What treatment should be given?
e. Discuss the prevention and control measures of the given disease?

4. Mumps:
 Mumps is an acute infectious disease that leads to painful
swelling of the Parotid glands (Salivary gland).
Mumps is caused by an MYXOVIRUS PAROTITIS (Mumps virus).
MC age group: Children (5-9 years).
Mumps shows life long immunity.

5.  Mumps is preventable by getting vaccinated with the mumps
vaccine, usually given in combination as the measles-mumps-rubella
(MMR) vaccine.

6. Epidemiology of Mumps:
The disease occurs throughout the world.
Mumps is an endemic disease in the world.
World: About 500,000 cases are reported to WHO annually.
Children (5-9 years).
Cases occur throughout the year, but the peak incidence is in winter and
spring.
Epidemics are often associated with overcrowding.
Epidemic peaks every 2-5 years.

7. Nepal:
Mumps is an endemic disease in Nepal.
In 2022, total mumps cases reported in Nepal was 8,898.

8. Epidemiological determinants of Mumps:
Agent factors Host factors Environmental factors
MYXOVIRUS PAROTITIS
(Mumps virus).
SOURCE OF INFECTION:
Clinical Cases and Sub
clinical.
Children (5-9 years)
Natural infection with
this virus is thought to
confer lifelong
protection.
Cases occur
throughout the year, but
the peak incidence is in
winter and
spring.
 Overcrowding.

9. Mumps:
Mode of transmission of Mumps: Respiratory disease(Air droplets)
Incubation period of Mumps: 14-21 days
Period of communicability: 4 days- Symptoms- 7days
SAR: >86%

10. Clinical finding suggestive of Mumps:
Pain and Swelling of Parotid glands
(Pain and swelling at temporomandibular joint).
Often the child complains of "ear ache" on the affected side prior to the
onset of swelling.
Fever
Headache
Myalgia
Sore throat

11. Complications of mumps:
Most common complications in Children: ASEPTIC MENINGITIS
Most common complications in Adolescents: Orchitis/ Oophoritis
Q. Most common complications: ASEPTIC MENINGITIS

12. Managements of mumps:
Mumps infection is usually self-limiting.
1. Apply Ice pack or Heat pack.
2. NSAIDs
3. Eat soft food
4. Plenty of fluids
5. Gargle with warm salt water

13. Prevention and control of mumps:
1. Active immunization: MMR vaccine
 Types: Live attenuated
Strain: EDMONSTON ZAGREB S
Age of administration: 9 months and 15 months
Route of administration: SUBCUTANEOUS (S/C)
Site of administration: R. Arm
Diluent: Distilled water/ Sterile water
2. Isolation: Cases should be isolated till the clinical manifestations subside.
3. Contacts should be kept under surveillance.
