==Overview==
==Overview==
Fever and skin rash are very common symptoms seen in pediatric populations both in clinic and hospital settings. Disease states associated with these symptoms are varied and can range from benign to extremely severe illness requiring prompt intervention in the emergency room or even ICU. Therefore, a vast knowledge of these disease states is very important as oftentimes, diagnosis is mainly clinical.
[[Fever]] and [[rash]] are [[symptoms]] encountered frequently in [[pediatrics]]. [[Disease states]] associated with these [[symptoms]] are varied. [[Febrile]] [[rashes]] can be classified based on [[morphology]], [[distribution of spread]], [[pattern]] of occurrence and cause. [[Fever]] results when [[exogenous]] ([[micro-organisms]]) and [[endogenous]] [[Pyrogen|pyrogens]] interact with the Organum Vasculosum of the Lamina Terminalis (OVLT) causing a rise in [[body temperature]] as a result of an increase in the [[hypothalamic]] [[set point]]. [[Fever]] and [[rash]] in kids are caused by [[infectious]] ([[bacterial]], [[viral]], [[fungal]], and [[protozoan]]) and non-[[infectious]] ([[drug]]-related [[Eruption|eruptions]] and [[Immune-mediated disease|immune-mediated]]) causes. [[Patients]] of all [[age]] groups may develop [[diseases]] that present with [[fever]] and [[rash]]. Common [[risk factors]] for the [[development]] of [[diseases]] that present with [[fever]] and [[rash]] include contact with [[Illness|ill]] individuals, poor/depressed [[immunity]], lack of [[vaccination]], very [[Young adult|young]] [[age]], and poor [[hand washing]] habits. The [[symptoms]] of [[diseases]] associated with [[fever]] and [[rash]] usually develop in the first few days from contact. The stages/phases of most [[infectious]] [[Process (anatomy)|processes]] include the [[incubation period]], [[prodromal]] [[Phase (matter)|phase]], [[illness]], decline, and [[convalescence]]. Rapid [[clinical]] [[diagnosis]] is necessary in severe cases to begin immediate [[empiric therapy]] while awaiting the test results. [[Triaging]] kids who present with [[fever]] and [[rash]] into three groups on basis of early [[symptoms and signs]] is essential for making prompt [[diagnosis]] and administering possible treatment regimen. Effective measures for [[primary prevention]] of [[fever]] and [[rash]] in [[children]] may include [[vaccination]], [[coughing]], and [[sneezing]] into [[elbows]] or [[tissue]], [[hand washing]], avoiding contact with [[Illness|ill]] individuals, [[Prevention|preventing]] exposure to [[tick bites]].

*Early clinical features include [manifestation 1], [manifestation 2], and [manifestation 3].
*If left untreated, [#%] of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
*Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].
*Prognosis is generally [excellent/good/poor], and the [1/5/10­year mortality/survival rate] of patients with [disease name] is approximately [#%].


== Diagnosis ==
==Epidemiology and Demographics==
In severe cases, quick clinical diagnosis is necessary in order to institute immediate empiric therapy while awaiting test results. It is therefore important to have detailed knowledge of symptoms and signs of the common diseases in kids that present with fever and rash.
===Age===
A practical approach to triage kids who present with fever and rash for near accurate diagnosis is to divide them into 3 groups:
* Group 1- Children presenting with severe illness and require immediate intervention based on history and physical examination
* Group 2- Children who present with recognizable viral syndromes that requires symptomatic treatment and reassurance.
* Group 3- Children with undifferentiated rashes which could either be benign or atypical presentation of serious illness. 


=== Symptoms ===
*[[Patients]] of all [[age]] [[Group (sociology)|groups]] may develop [[diseases]] that present with [[fever]] and [[rash]].
Besides fever and rash, other symptoms of possible diseases includes the following:
* runny nose
* cough
* sore throat
* history of upper respiratory tract infection or diarrheal illness
* earache
* red watery eyes (conjunctivitis)
* pruritus (which could be severe in drug related rashes)
* poor appetite
* headaches
* diarrhea
* pallor
* irritability
* pains in certain body areas (arthritis)
Important details to watch out for in the history include:
* time of onset and progression of symptoms
* location of the rash(central or peripheral) and the rate of emergence
* seasonal occurrence
* recent travel
* contact with an ill individual or animal
* detailed medication history (especially sulfonamides, NSAIDs and anticonvulsants)
* exposure to forest or other natural environment
* also important to evaluate the immune status of the patient


=== Physical Examination ===
===Race===
In addition to symptoms already listed above, additional findings on examination include;
* state of the child (how ill?)
* rash morphology and its location/distribution
* lymph node enlargement

Overview

Fever and rash are symptoms encountered frequently in pediatrics. Disease states associated with these symptoms are varied. Febrile rashes can be classified based on morphology, distribution of spread, pattern of occurrence and cause. Fever results when exogenous (micro-organisms) and endogenous pyrogens interact with the Organum Vasculosum of the Lamina Terminalis (OVLT) causing a rise in body temperature as a result of an increase in the hypothalamic set point. Fever and rash in kids are caused by infectious (bacterial, viral, fungal, and protozoan) and non-infectious (drug-related eruptions and immune-mediated) causes. Patients of all age groups may develop diseases that present with fever and rash. Common risk factors for the development of diseases that present with fever and rash include contact with ill individuals, poor/depressed immunity, lack of vaccination, very young age, and poor hand washing habits. The symptoms of diseases associated with fever and rash usually develop in the first few days from contact. The stages/phases of most infectious processes include the incubation period, prodromal phase, illness, decline, and convalescence. Rapid clinical diagnosis is necessary in severe cases to begin immediate empiric therapy while awaiting the test results. Triaging kids who present with fever and rash into three groups on basis of early symptoms and signs is essential for making prompt diagnosis and administering possible treatment regimen. Effective measures for primary prevention of fever and rash in children may include vaccination, coughing, and sneezing into elbows or tissue, hand washing, avoiding contact with ill individuals, preventing exposure to tick bites.
