Mumps Virus Pathogenesis Clinical Features
Mumps Mumps Mumps is an acute viral illness. Parotitis and orchitis were described by Hippocrates in the 5th century BCE. In 1934, Johnson and Goodpasture showed that mumps could be transmitted from infected patients to rhesus monkeys and demonstrated that mumps was caused by a filterable agent present in saliva. This agent was later shown to be a virus. Mumps was a frequent cause of outbreaks among military personnel in the prevaccine era, and was one of the most common causes of aseptic meningitis and sensorineural deafness in childhood. During World War I, only influenza and gonorrhea were more common causes of hospitalization among soldiers. Outbreaks of mumps have been reported among military personnel as recently as 1986. Mumps Virus Mumps virus is a paramyxovirus in the same group as parainfluenza and Newcastle disease virus. Parainfluenza and Newcastle disease viruses produce antibodies that cross- 11 react with mumps virus. The virus has a single-stranded RNA genome. The virus can be isolated or propagated in cultures of various human and monkey tissues and in embryonated eggs. It has been recovered from the saliva, cerebrospinal fluid, urine, blood, milk, and infected tissues of patients with mumps. Mumps virus is rapidly inactivated by formalin, ether, chloroform, heat, and ultraviolet light. Pathogenesis The virus is acquired by respiratory droplets. It replicates in the nasopharynx and regional lymph nodes. After 12–25 days a viremia occurs, which lasts from 3 to 5 days. During the viremia, the virus spreads to multiple tissues, including the meninges, and glands such as the salivary, pancreas, testes, and ovaries. -

Managing Communicable Diseases in Child Care Settings
MANAGING COMMUNICABLE DISEASES IN CHILD CARE SETTINGS Prepared jointly by: Child Care Licensing Division Michigan Department of Licensing and Regulatory Affairs and Divisions of Communicable Disease & Immunization Michigan Department of Health and Human Services Ways to Keep Children and Adults Healthy It is very common for children and adults to become ill in a child care setting. There are a number of steps child care providers and staff can take to prevent or reduce the incidents of illness among children and adults in the child care setting. You can also refer to the publication Let’s Keep It Healthy – Policies and Procedures for a Safe and Healthy Environment. Hand Washing Hand washing is one of the most effective way to prevent the spread of illness. Hands should be washed frequently including after diapering, toileting, caring for an ill child, and coming into contact with bodily fluids (such as nose wiping), before feeding, eating and handling food, and at any time hands are soiled. Note: The use of disposable gloves during diapering does not eliminate the need for hand washing. The use of gloves is not required during diapering. However, if gloves are used, caregivers must still wash their hands after each diaper change. Instructions for effective hand washing are: 1. Wet hands under warm, running water. 2. Apply liquid soap. Antibacterial soap is not recommended. 3. Vigorously rub hands together for at least 20 seconds to lather all surfaces of the hands. Pay special attention to cleaning under fingernails and thumbs. 4. Thoroughly rinse hands under warm, running water. 5. -

Mumps Fact Sheet Department of Health
Mumps Fact Sheet Department of Health Mumps What is mumps? Mumps is a disease caused by a virus. You can catch mumps through the air from an infected person’s cough or sneeze. You can also get it by direct contact with an infected surface. The virus usually makes you feel sick and causes a salivary gland between your jaw and ear to swell. Other body tissues can become infected too. What are the symptoms? After a person is exposed to mumps, symptoms usually appear in 16 to18 days. But, it can take 12 to 25 days after exposure. The symptoms are usually: • Low-grade fever • Headache • Muscle aches • Stiff neck • Fatigue • Loss of appetite • Swelling and tenderness of one or more of the salivary glands • Some people have just mild symptoms, or no symptoms. What are the complications of mumps? Severe complications are rare. A small number of people may have inflammation of the brain and tissues that cover the brain and spinal cord (encephalitis/meningitis). Or, they may have inflammation of the testicles, ovaries or breasts. Deafness or spontaneous abortion may also occur. How long is a person with mumps contagious? A person with mumps can pass it to others from 2 to 3 days before the swelling starts until five daysafter the swelling begins. Is there a treatment for mumps? There is no treatment. Acetaminophen or ibuprofen can ease fever and pain. If my child or another family member has been exposed to mumps, what should I do? Immediately call your local health department, doctor or clinic for advice. -

Managing CD in Childcare Setting
MANAGING COMMUNICABLE DISEASES IN CHILD CARE SETTINGS There are a number of steps providers and staff of child care homes and centers can take to prevent or reduce the incidents of illness among children and adults in the child care setting. Prepared jointly by: Bureau of Children and Adult Licensing Michigan Department of Human Services and Divisions of Communicable Disease & Immunization Michigan Department of Community Health Daily Steps to Keep Children and Adults Healthy To provide for a healthier and safer environment on a daily basis the following steps should be taken: 1. Wash hands of children and adults frequently with soap and warm running water especially after diapering, toileting, and nose wiping, as well as before feeding, eating and handling food, for at least 20 seconds. Alcohol-based hand rub with at least 60 percent alcohol content may be used if running water is not available or if hands are not visibly soiled. 2. Dry hands with single-service paper towels and turn off the faucet with the paper towel or use an air blow dryer. 3. Provide tissues throughout the home or center. Staff should use tissues, individually and often, to wipe young children’s nasal drainage. Remember to wash hands after each wipe. 4. Teach children (and adults) to cough or sneeze into tissue or their sleeve and not onto others, food or food service utensils. 5. Careful observation by caregivers for a change in a child’s appearance or behavior that might indicate beginning illness. Observations should be communicated to the parent so that medical advice and diagnosis can be sought. -
