    Family history- anyone have asthma or any other chronic diseases and malignancy

    Physical examination
    Vital sign- BP,PR, RR,Temp
    General-hydrational status, any skin rash, pallor, lymp node enlargement
    Throat examination- check for injected throat/ tonsillitis
    Don’t forget to check ear and nose as well because ear, nose and throat are connected to each other so the problem might come from one if this
    Respiratory examination- check if there dullness on percussion, reduce air entry and vocal resonance and any rhonci or crepitation(to exclude lung infection)
    Management (for viral fever)
    -patient education
    From what you tell me and examination, you might have a viral fever. It is a self-limiting infection so no need to take any antibiotic just make sure that’s you get enough sleep and rest, drink a a lot of plain water and avoid close contact with other because it is infectious.
    -Lifestyle modification
    Take a good diet and do regular exercise to improve your immune system
    -investigation
    FBC- check WBC, Hb, platelet(to exclude bacterial infection)
    -medication
    Analgesic- paracetamol / aspirin
    Cough mixture- diphenhydramine
    Refer to drug discussion for detailed.
    Safety netting
    • To came back again if fever not settled (most of viral fever settled completely within a week), any severe abdominal pain, vomiting, marked changes in body temperature, from fever to low temperature change in mental status such as irritability or lethargy(warning sign for dengue fever)

  2. Thank you for your answer

    Medications:
    symptom relief -
    1)antipyretic: PCM 1g Qid/ PRN
    we don't normally give aspirin
    2) syp benadryl 15mls TDS/ PRN (cough)
    3) antihistamine - actifed/ piriton
    4) no need for antibiotics as it is viral in origin

    You check FBC TRO viral thrombocytopenia and also to exclude bacterial infection as you mentioned

    Viral fever is self limiting - normally last for 4-5 days and resolve by one week as you mentioned

    warning signs for DF MUST also include any bleeding tendnecies such nose bleed, PR bleed, haemoptysis, hemetemesis, gum bleed and heavy menses

    the other important warning signs of DF is abdominal pain( eigastric pain) with inability to tolerate orally (nausea/ poor appetite with vomitting +/- diarrhea)

    Bed rest and increase fluid intakes (any fluids) is the best advise for viral fever. Advise taking soups/ porridge if they have poor appetite. Exercising may be a bit too much for them.

    DO you know what is the name of the criterias to differentiate between viral and bacterial infections in a patient presenting with fever, cough and RN?

  4. Recommendation is that antibiotics (either penn v, amoxycillin or erythromicin) should be started in urti pts if they have at least 3 out of 4 criteria (tonsillar exudate, fever T> 38, cervical LN, absent of cough). This criteria indicates that the urti is bacteria rather than viral.

  5. The name of the criteria is McIsaac criteria. Please refer to Cpg sore throat.
