History of present illness
- Chief complaint
- I have a really sore throat.
- It is mostly the back of my throat.
- Intensity (on a scale from 0–10)
- I would say at least a 7, maybe an 8.
- It is almost a burning pain.
- It started last night.
- Precipitating events
- I think it is getting worse.
- Previous episodes
- Maybe as a child. But nothing recently.
- Alleviating factors
- Cold drinks really help.

- I also woke up with a really hoarse voice this morning.
- Previous episodes of hoarse voice
- Problems swallowing food
- Yes, it really hurts to eat or swallow so I have not really had anything to eat since yesterday.
- Able to swallow liquids
- No, I have no problem getting liquids down – but it is really painful.
Review of systems specific to sore throat
- Yes, my throat is so swollen that I really feel a bit nauseous when I talk. But I have not thrown up.
- I think so. I definitely had chills yesterday in the evening. Did the nurse not take my temperature when I got here?

- Shortness of breath
- I do not have much of an appetite right now.

- Well I am really hoarse.
- Hmm, not sure but I have kind of a gross taste in my mouth and I feel like it smells.
- Abdominal pain
- My whole belly has been hurting a little bit all day today. But it is very mild.
It is important to ask for symptoms of a common cold (rhinitis and/or headache) in patients who present with sore throat, as they are typical for viral tonsillitis but would not be expected in streptococcal pharyngitis.
Past medical history, family history, and social history
- Past medical history
- Ill contacts
- My girlfriend says she has also had a sore throat for the past couple of weeks.
- Past surgical history
- Family history
- My dad has diabetes.
- I go to college and am majoring in criminal justice, but mostly I am interested in playing football for the college team.
- I live in a dorm on campus.
- I drink 1–2 beers on the weekends. During the week I always have football practice, so I do not have time to go out or drink.
- Recreational drugs
- Football practice almost every day.
- Sexually active
- With whom
- Well, for the past 2 months, my girlfriend. And before that just a few different girls around campus.
- Men or women
- What kind of a question is that? Only women.
- Number of partners over the past year
- Dude, you are asking quite a few questions about this. Maybe 9? 10?
- Yes, I always use a condom. The last thing I need is to get one of these girls pregnant.
Obtaining a focused sexual history is important in patients presenting with a sore throat. Unprotected sex is a risk factor for HIV, and an acute HIV infection can present with sore throat (mononucleosis-like syndrome).

Counseling and challenge
- Examinee offered
- Examinee reacted appropriately to challenge.
Suggested response to challenge: “Mr. Soto, I understand that you are not feeling well and that you would like to get back home as quickly as possible. However, at this time I cannot say with certainty whether your symptoms are caused by a bacterial or viral infection. Antibiotics would only be appropriate if bacteria were causing your symptoms, and otherwise they could do more harm than good, or even cause a rash. I would like to run some tests to figure out the exact cause of your symptoms and then discuss the appropriate treatment with you. Does that sound okay?”
- Streptococcal tonsillopharyngitis: This patient's sudden-onset sore throat, tender cervical lymphadenopathy, fever, and lack of cough or other symptoms of cold meet the criteria for microbiologic testing for group A streptococcal (GAS) pharyngitis. Although tonsillar exudates are often found in streptococcal tonsillopharyngitis, they are not always present, and the palatal petechiae seen in this patient are also a typical feature of strep throat. If he is found positive, he should be treated with antibiotics to prevent rheumatic fever and poststreptococcal glomerulonephritis.
- Infectious mononucleosis (IM): IM can present similarly to bacterial pharyngitis (e.g., sore throat, lymphadenopathy, fever, fatigue) and is common in young adults. It is of particular concern in this case because of the patient's mild abdominal pain, which could indicate splenomegaly, a common finding in IM. Since splenomegaly can lead to life-threatening splenic rupture and this patient is an avid football player, he should be discouraged from playing until his IM has subsided. However, because he does not have generalized lymphadenopathy or the grayish-white deposits on the tonsils typically seen in IM, it is only the second most likely diagnosis.
- Viral pharyngitis: Viral pharyngitis could also be the cause of this patient's sore throat and erythematous oropharynx. However, his fever and lack of symptoms of cold make this diagnosis less likely than the first two.
- Throat swab allows for simple and quick detection of :group A streptococcal infection (highly specific, sensitivity 70–90%). In cases in which rapid strep testing is negative, throat culture can be used as a follow-up test.
- CBC: Not specific, but can help differentiate viral from bacterial infections. Leukocytosis is generally more common in bacterial pharyngitis, whereas lymphocytosis is more common in viral pharyngitis and infectious mononucleosis.
- Peripheral blood smear: Atypical T lymphocytes can be observed on peripheral smear in infectious mononucleosis.
- Monospot test: Confirms diagnosis of infectious mononucleosis if positive (100% specificity). If monospot testing is negative but mononucleosis is suspected, anti-EBV antibodies can be used for diagnosis.
