  • Lesions can appear on the scalp, in the mouth, ears, genital regions and armpits

  • Disease is spread by droplets in the air and by contact with the watery blisters.

Scarlet Fever

1-3 days feeling very tired, sore throat, fever, and vomiting.

Brief, nonspecific illness consisting of fever, malaise, myalgias, and headache. Often spreads in epidemics among children.

Red, flushed cheeks, reddened face with white ring around the mouth, red lace-like rash on trunk and extremities. Lasting 7-9 days.

  • Sunlight makes rash worse.

  • Face has “slapped cheek” appearance.

  • May fade and recur for few weeks.

Virus shed in stool, good handwashing important!







DISEASE


SIGN/SYMPTOMS

TYPE OF RASH

OTHER FEATURES

Impetigo

Rash appears as little pin sized “pimples” but evolves quickly into major skin eruptions filled with pus.

Begins as pin sized blisters that break, allowing the discharge to spread on the skin surface, causing skin breakdown. White or yellow crust form at the sites, can cover large areas if untreated.

  • Children often have this rash around the mouth particularly under the nose and chin.

  • Impetigo “itches”

  • Handwashing important

  • Treatment with antibiotics

*Heat Rash*

(Prickly heat)




Often appears in moist skin folds of legs, arms, & neck; also at waistline and on buttocks

Bands or reddened areas or patches of reddened areas.

  • Heat rash is a result of hot, humid weather conditions and the skin contact with itself, diapers or clothing. Most often associated with plastic diaper pants or disposable diaper plastic irritating the skin surface and increasing stimulus of sweat glands.

Diaper Rash

Reddened skin on buttocks, or “diaper area” as a result of irritation or infection from stool, urine or prolonged skin contact with plastic diapering materials. Develops in moist areas.

Rash can be generalized reddened skin surface, evolving to blistered appearance and skin breakdown, with inflamed, moist and bleeding patches. This rash causes discomfort and pain.

“ Diaper rash” can be caused by prolonged contact with soiled diapers; however, some viral or fungal organisms may cause sores and blistering appearance.

Drug or food reaction


Occasionally fever, red, runny eyes, sores in the mouth, genital regions, and asthma like symptoms to extreme difficulty breathing.

Rash may appear as raised skin areas like “welts” or as “hives” in a cluster. Itching usually present. Rash may appear quickly, may be isolated areas to a complete body rash.

  • Discuss introduction of medicines or new foods to prevent further illness.

  • Can appear quickly and be serious. (This rash appears for no other apparent reason.)

Smallpox

Fever for 2-4 days before rash, extremely ill.

Rash starts with small bumps on face and upper arms, then spreads over the whole body, more concentrated on extremities and face. The lesions become blistered, then filled with pus, then scab over.

  • Rash is most often confused with early chickenpox




  • Fever and severe illness for several days before rash onset suggests smallpox and not chickenpox.
