COMMUNICABLE DISEASECommunicable diseases are those diseases which may be transmitted from person to person. (When a communicable disease is suspected, please keep in mind that this is a confidential matter.)
Communicable disease can be transmitted via any of the following routes:
Direct contact with infected individuals or body fluids.
Contact with contaminated objects such as clothing, bed linen, equipment, or other belongings.
Droplet spread by coughing, sneezing, or talking.
Airborne dust/particles or moisture in the air.
Contaminated food and water.
Some of the following signs and symptoms may indicate the beginning of a
Fever (over 100.4) Jaundice Red and/or draining eye(s) Chills Nausea Sore throat Cough Pain Stiff neck with fever Headache Rash Vomiting Controlling Communicable Disease in Schools Any person who is suspected of having a communicable disease should be excluded from school by the principal. The student will need to remain in the health room, isolated, if possible, until arrangements are made for him/her to be taken home.
When available, the professional judgment of the RN shall be used to determine the exclusion/readmission to school, based on established protocols, in accordance with standard medical procedures and practice. A written statement from the student’s licensed health care provider that the person is free from communicable disease is required for readmission to school. If parent/guardian identifies Chickenpox, no note from doctor is required but student may not return to school until all lesions are dried to the crust stage.
Persons at increased risk for complications include:
Individuals with immune system disorders.
Individuals with sickle cell disease.
Individuals on steroid therapy.
Individuals on chemotherapy.
Individuals who are organ transplant recipients.
Individuals with tracheostomies.
CHICKENPOXSigns and Symptoms Young children - fever, headache, tiredness, loss of appetite, about the same time as rash appears.
Older children and adults - above signs and symptoms may appear one or two days before onset of rash.
Rash A rash may change in appearance rapidly. Sequence of rash: (1) flat red spot (2) elevated area containing clear fluid (3) crusted lesions. All stages of the rash may appear on any area of the body at one time. Rash most dense on trunk; less dense on arms, legs and face, including scalp and inside of nose and mouth.
Cause Varicella - zoster virus Incubation Period From contact to the development of signs and symptoms: usually 14-16 days. May be as short as 10 days or as long as 21 days.
Transmission Person is infectious to others 1-2 days prior to eruption of rash and until ALL lesions are dry and crusted (approximately 5-6 days). Transmission directly from lesions or droplet, coughing, etc. or indirectly from clothing freshly soiled by discharge from vesicles or mucous membranes of infected person.
Treatment Itching may be minimized by soaking in water with baking soda or oatmeal. Physicians will sometimes prescribe antihistamines if a child is uncomfortable or irritable. Body temperature control may be necessary with some children. Do not give aspirin or Pepto Bismol.
Complications Uncommon. Reye's Syndrome has been associated with chickenpox. Immunocompromised children are at higher risk for complications. They may experience prolonged eruption of lesions and high fever, and are contagious throughout this period.
Immunization Varicella Zoster vaccine (Varivax) is available through private pediatricians and the Sumter County Health Department. Immunization after exposure can lessen the severity of the disease. Clinical illness after re-exposure is rare, but may occur particularly in immunocompromised persons.
School Action Encourage parent/guardian to report cases to school office.
The student is excluded from school until all lesions are dried to the crust stage.
Contact the school RN if you have any questions.
FIFTH DISEASE (Erythema Infectiosum) Signs and Symptoms First signs and symptoms are low grade fever, malaise, and a rash on the cheeks that gives a flushed appearance (sometimes referred to as a "slapped face" look). Within two or three days the “lacy look”, a slightly raised rash, will spread to the arms, legs and trunk, usually not appearing on the palms or soles. The duration of the illness is normally 5 to 10 days.
The rash will sometimes recur for several weeks, particularly when the individual is exposed to sunlight or heat, exercise, or stress.
Cause Parvovirus B19 Incubation Period Time from contact to the development of signs and symptoms ranges from 4 to 20 days.
Transmission Transmitted primarily through contact with infected respiratory secretions. May be transmitted from mother to unborn child.
Treatment Parent/guardian should be urged to take children with the above symptoms to a physician to be diagnosed.
Complications Exposed pregnant women should notify their obstetrician.
School Action For re-entry to school: If rash is present, a physician statement of diagnosis and "not contagious” must accompany the student.
Student should not be in school if they have a fever.
INFECTIOUS HEPATITIS (Hepatitis A) Signs and Symptoms Fever, loss of appetite, vomiting, abdominal discomfort, indefinite feeling of being ill.
Dark urine (coffee color) with light stools may be noticed. Yellow (jaundice) color of the skin and the whites of the eyes follow this in a few days. Severity increases with age.
Children are more apt to have mild cases, frequently without jaundice.
Cause Hepatitis virus, Type A Incubation Period Time from contact until the development of signs and symptoms 15-50 days, average of 28-30 days.
Transmission The virus is present in intestinal contents of infected persons and is passed in bowel movements. Where sanitation is poor, the virus can be transferred from sewage to drinking water, milk, vegetables, and seafood. Close person-to-person contact, the use of contaminated articles, and failing to wash hands thoroughly after handling contaminated objects can be sources of transmission. Person becomes infectious to others approximately two weeks before jaundice appears and remains infectious for about one week following evidence of jaundice.
Treatment A physician should see all cases of suspected hepatitis. Severity of cases can vary from illness of 1 to 2 weeks to an occasionally disabling disease of several months. Bed rest and careful observation are recommended until signs and symptoms have subsided.
Complications Severity tends to increase with age, but complete recovery is the rule.
Immunization There is a vaccine against Type A Hepatitis. Close contacts of confirmed hepatitis cases such as household members, persons exposed in day care centers or other group living situations, or persons known to be exposed to contaminated food or water should receive immune globulin as soon after exposure as possible. Immune globulin provides protection for about two months.
Prevention It is better to avoid this disease by good personal and household hygiene, sanitary disposal of body wastes, training children in good toilet habits and HANDWASHING.
HEPATITIS B Signs and Symptoms Gradually developing loss of appetite, abdominal discomfort, nausea, and vomiting.
Sometimes joint pain and rash occurs. Often jaundice (yellowish tint of eyes and skin) appears later. Fever may or may not be present. Seriousness of illness varies.
Cause Hepatitis B virus (HBV) Incubation Period Usually 45-180 days, average 60-90 days.
Transmission The virus is passed either directly from those who are already infected or indirectly from their body fluids. The virus can live on a surface for up to 30 days.
The most common ways of getting the disease are:
Through needle stick or needle sharing.
Through breaks in the skin by way of cuts or scrapes and exposure to blood or other body fluids.
Through exposure to blood or other body fluids via the eyes or mouth.
Through sexual contact.
Through body piercing or tattooing.
Treatment Studies with antiviral drugs are in progress.
Complications Acute hepatic necrosis (liver tissue death), cirrhosis of the liver, liver cancer, chronic hepatitis, with or without symptoms, or death.
Immunization Hepatitis B vaccine is routine for infants and adolescents and is also indicated for persons with high risk of exposure to hepatitis. Immunoglobulin (IG or HBIG) is used to immunize known contacts of persons with hepatitis.
School Action Utilize standard precautions in handling body fluids and items contaminated with body fluids.
Emphasize good personal hygiene, particularly hand washing, to all students and staff members.
IMPETIGO Signs and Symptoms Lesions, yellow to red, weeping and crusted or pustular, especially around the nose, mouth and cheeks, or on the extremities. Early lesions are raised and contain fluid, later they contain pus, and finally become crusted.
Cause Staphylococcal and streptococcal organisms (bacteria) Incubation Period Variable and indefinite. Commonly 4-10 days.
Transmission Impetigo is extremely contagious and is usually transmitted by contaminated hands, particularly where there are open draining areas. Easily transmitted by direct contact with infected persons. The hands are the most important instrument for transmitting infection.
Good hand washing is vital.
Treatment Application of an antibiotic ointment, after soaking crusts in mild, soapy water. If infection is widespread, physicians will sometimes prescribe oral antibiotics.
Possible Complication Seldom scarring. Occasionally enlarged lymph nodes, which may indicate extensive infection or accompanying infection.
Signs and Symptoms Fever, general malaise, conjunctivitis, runny nose, and a cough start three to four days before rash appears and continue for approximately 10 days.
Rash Rash appears first on face and neck and progresses down to involve trunk, arms and legs.
On the fifth day after the rash appears, it begins to fade. Some scaling of skin on trunk may occur.
Cause Measles Rubella virus Incubation Period Time from contact to development of disease is 7-18 days.
Transmission Airborne droplet or direct contact with nasal or throat secretions of infected persons. Child is infectious from first signs of illness until 5 or 6 days after rash appears.
Treatment Physician or health department should be contacted so diagnosis can be confirmed.
Parent/guardian should seek assistance from physician in dealing with child's signs and symptoms.
Complications - Most serious: encephalitis. Others: deafness, otitis media, croup, pneumonia, diarrhea.
Immunization Available. Should be administered after 12 months of age and again between 4-6 years of age. Usually given with rubella and mump vaccines as MMR.
School Action Emphasize good personal hygiene, particularly hand washing, to all students and staff members.
INFECTIOUS MONONUCLEOSIS (MONO)Signs and Symptoms Sore throat, malaise, swollen lymph nodes, and fever. In young children the disease is generally mild and more difficult to recognize. Most commonly recognized in high school and college students.
Cause Epstein-Barr virus Incubation Period Time from contact to the development of signs and symptoms - 4 to 6 weeks.
Transmission Virus is transmitted from person to person through saliva either directly or indirectly from contact with eating utensils, drinking glasses or beverage containers.
Treatment In the early stages of mononucleosis, the primary management strategy is rest. Many physicians feel that physical exertion and stress may prolong the course of symptoms or precipitate relapse. This appears to be more of a problem in adolescents or young adults, many of whom complain of fatigue, with or without exertion, weeks or months after the onset of symptoms.
Complications Uncommon Immunization None available School Action Students with infectious mononucleosis can re-enter school as soon as symptoms subside and they are feeling well.
They should present a note from a physician stating limitations of physical activity when returning to school.
Most young children do not require restriction of activities.
MUMPS Signs and Symptoms Fever, swelling and tenderness of one or more of the salivary glands.
Cause Virus Paramyxovirus Incubation Period Time from contact until the development of signs and symptoms - 14-21 days.
Transmission By droplet (coughing, sneezing, etc.) and by direct contact with saliva of infected person.
Most infectious 24-48 hours before illness begins and can continue as long as 9 days after swelling is first observed.
Treatment Parent/guardian should seek assistance from physicians in dealing with signs and symptoms. Bed rest with observation of signs and symptoms is recommended.
Complications Hearing impairment (rare) Immunization Available. Should be administered after 12 months of age. Usually given with measles and rubella vaccines as MMR.
School Action Emphasize good personal hygiene, particularly hand washing, to all students and staff members.
PINK EYE (Acute Contagious Conjunctivitis) Signs and Symptoms Tearing, irritation, inflammation (redness) of the conjunctiva (lining of eyelids and covering of eye), swollen eyelids, crusting or discharge in one or both eyes.
Causes Acute bacterial, viral, or allergic Incubation Period Bacterial is usually 24 to 72 hours.
