Communicable
Diseases
Rubella, Rubeola, Roseola,
Fifth’s Disease, Chicken Pox, Scarlet Fever, Mononucleosis

Review terminology r/t communicable
diseases:
◦

Incubation period
Prodromal symptoms
Period of communicability
Types of Isolation: contact, respiratory

Immunizations can prevent many of these
diseases—primary prevention strategy
Careful handwashing to prevent transmission
in essential for healthcare practitioners and
for families
Infection Control: pp. 1019-1020 & Box 27-3
(9th ed.); pp. 193-195 & Box 6-1 (10th ed.)
Early identification of symptoms so that
treatment can be initiated is also paramount
to a good outcome.
Prevention


If a child is admitted to the hospital with an
UNDIAGNOSED EXANTHEMA, strict isolation is
instituted until a diagnosis is confirmed.
These are a few communicable diseases that require isolation:

diphtheria
chickenpox
Measles, mumps, rubella
tuberculosis
adenovirus
Haemophilus influenzae type B
influenza
meningitis
Mycoplasma pneumonia, pseudomonas aeroginosa pneumonia
pertussis
RSV
streptococcal pharyngitis, scarlet fever
Clostridium difficile, e.coli, shigella
pneumonia / pneumonic plague /


Any immunocompromised children—those
receiving steroid or immunosuppressive
therapy, are always at risk for viremia,
especially from viruses like herpes zoster.

Children with sickle cell anemia may develop
aplastic anemia from erythema infectiosum
(EI)[Fifth’s Dz]. The human parvovirus
(HPV) infects and lyses RBC precursors.

Diphtheria and Scarlet Fever are bacterial
and prevention of complications requires
compliance with antibiotic therapy.
Prevent complications

High-risk children exposed to chickenpox
should receive VZIG (varicella zoster immune
globulin).

Acyclovir (Zovirax) may be used to treat
varicella infections in high risk children with
the disease.

Vitamin A supplementation in high doses has
recently been shown to decrease morbidity
and mortality rates in measles. Careful
instruction to parents on safe storage of
Vitamin A is essential.
Prevent complications

Alleviate itching that is one of the most
common discomforts of rashes
◦ Cool/tepid baths without soap, may use oatmeal
◦ Calamine/Caladryl lotions must be applied sparingly
to prevent toxic levels being absorbed. They
contain diphenhydramine.
◦ Wear lightweight, loose clothing, keep cool
◦ Keep nails short, wear mittens on young children
◦ Suggest po. Diphenhydramine (Benadryl)



Offer antipyretics (acetominophen or
ibuprofen) for fever and general malaise
Lozenges, saline rinses for sore throats
Suggest quiet activities
Provide comfort
Provide accurate information re: period of
communicability and period of recovery.
 Provide support and encouragement.
 Review importance of compliance with
therapy.
 No Salicylate products with all viral
diseases because of link to
Reye Syndrome (p.1462-3 10th ed.)—

metabolic encephalopathy: fever, profoundly
impaired consciousness, and liver dysfunction.
Support family and child

Review Table 16-1 Communicable Diseases of
Childhood pp. 608-614 (Hockenberry et al, 9th ed.)
 Table 6-2 in 10th ed. Pp. 212-218

Know association of high fever and febrile seizures with
Roseola and importance of careful antipyretic
management.

Know common sx of Rubeola (measles) including koplik’s
spots, photophobia.

Know period of communicability of Varicella/chickenpox
and appropriate counsel to parents re: when child can
return to school

Know etiology of Scarlet Fever, common sx, management,
and when to return to school

Know risks to fetus if Rubella is contracted in the mother’s
first trimester of pregnancy

Know appearance of rash for Fifth Disease (HPV)
Which is which??
Fifth Disease
Roseola
Chicken pox
Scarlet Fever
Etiology: Epstein Barr Virus
 Natural Hx:

◦
◦
◦
◦
◦
◦
Typically self-limiting & uncomplicated
-7Incubation period: 30-60 days
Preclinical stage: 3-5 days
Acute illness: 7-20 days
Convalescence: 2-6 weeks
Viral excretion may occur many months after
infection
◦ Often asymptomatic and difficult to diagnose
Mononucleosis
(pp.1175-7 10th ed.)
Transmission: through saliva (usually
intimate contact, thus the nickname,
‘Kissing Disease’)
 Pathophysiology

◦ EBV infects B-lymphocytes lymphoproliferation
◦ Lab results: atypical lymphocytes called Downey cells




 WBC’s especially lymphs and
 liver enzymes
EBV antibody titer 
+ Monospot test
Mononucleosis (cont’d)

Signs and Symptoms
◦ General malaise
◦ Sore throat, gelatinous film over palate and
uvula, red macules on palate
◦ Tonsillar enlargement, white exudate on
tonsils, red pharynx
◦ Fever
◦ Macular rash (trunk)
◦ Abdominal pain
◦ Cervical lymphadenopathy
◦ Splenomegaly
◦ Hepatomegaly
Mononucleosis (Cont’d)
Population most affected:12-26 yr olds
 Nursing concerns


◦
◦
◦
Potential for secondary infection
Potential for injury
School absenteeism
Possible complications:
 Aseptic meningitis
 Encephalitis
 Guillian Barré Syndrome
 Splenic rupture
Mononucleosis (cont’d)

Primary prevention
◦ General health promotion measures

Secondary prevention
◦ Prompt medical attention for sore throats to r/o strep
throat
◦ Screening to r/o secondary bacterial infection

Tertiary prevention
◦ Palliative:
 Fever (rest,  calories,  fluids, Acetominophen
 Saline gargles
 Soft foods
◦ No contact sports
◦ Referral for home-bound teacher, if pt has to
stay home for lack of energy and malaise
◦ Can go to school if feels up to it

That should do it!
Wash your hands and stop the
spread of these communicable
diseases!
