Overview
COVID-19 is a rapidly evolving situation and a heterogenous disease entity. A suspected or confirmed CVOVID-19 patient can have as common finding as fever and as unique yet significant finding as anosmia. Although, the most common physical examination findings in patients infected with coronavirus include fever, cough, and shortness of breath.[1] The patient may just have abdominal pain and tenderness on examination.[2] The general appearance of the patient infected with coronavirus-19 depends on the severity of the illness. High clinical suspicion and careful physical exam are they key to early diagnosis and treatment of SARS CoV2 infection.
Physical Examination
Physical exam of a suspected or confirmed case of SARS CoV2 patient should be conducted in a private room, preferably a negative pressure one. The examiner should have PPE that includes gloves, gowns or aprons, masks, or respirators covering the mouth and nose, goggles, and face shields.[3] If possible and the patient is in no respiratory distress, patient should wear a surgical mask.[4]
Appearance of the Patient
- General appearance of the patient infected with coronavirus depends on the severity of the illness.
- Patients with mild disease may appear healthy.
- Patients will appear sick, lethargic, and short of breath in severe disease.
Vital Signs
- Heart rate: A healthy asymptomatic patient may have a normal heart rate but that does not rule out infection. Increased heart rate can be due to fever, hypoxia, shock due to sepsis, and anxiety.
- Temperature:High fever (>100.4°F )[5]
- Respiratory rate:
- Oxygen saturation:
- Blood pressure:
Skin
- Skin examination of patients with COVID-19 includes the following lesions:
- Erythema multiforme-like[6] Further studies are required to evaluate exact etiology these lesions to be COVID-19, drug intake or any other conditions.
- Erythematous maculo-papular[7]: Acral eruption of erythemato‐violaceous papules and macules, with possible bullous evolution, or digital swelling can be seen.
- Urticarial[8][9]
- Chickenpox-like[8][10]
- Purpuric peri-flexural[11]
- Transient livedo reticularis[12]
- Acro-ischemic[13]: The lesion constitutes finger or toe cyanosis, skin bullae and dry gangrene.
- Chilblain-like[14]:They constitute bilateral red-purple papules on the dorsum of the fingers and diffuse erythema in the subungual area of thumb. Late in the SARS CoV2 disease course, pseudo‐chilblain pattern frequently appear.
- COVID-19 Toes: Toes and fingers turn purple or pink as happens during cold. It is mostly seen in younger patients. A patient presented with purple toes should be tested for COVID-19 virus infection.
HEENT
- Head examination:
- Eye examination:
- Conjunctivitis: has been reported but there is no well established data regarding this manifestation.[15]
- Epiphora: Patients can have teary eyes due to conjunctivitis itself or foreign body sensation.[16]
- Although there are no reports of blurred vision but visual acuity should be accessed.
- Ear exam:
- Nasal exam:
- Throat exam:
Neck
- A patient with severe hypoxia will be using accessory muscles for respiration visible on the neck exam.
- Jugular venous pressure:[17]
- High JVP or Jugular Venous Distension (JVD) can be a sign of COVID-19-associated heart failure or COVID-19-associated myocarditis.
- Low JVP: shows low CVP indication low intravascular volume. In patients with COVID-19 associated ARDS, CVP guides the fluid management.
Lungs
- Coronavirus infection mimics the pulmonary examination findings of pneumonia, such as:
- Increased respiratory rate[18]
- Percussion dullness
- Bronchial or decreased breath sounds
may reveal increased work of breathing using accessory muscles, circumoral cyanosis, and/or confusion from hypoxia. Lung sounds initially are unremarkable, but the patient can develop a mild expiratory wheeze
Heart
Abdomen
- Abdominal examination of patients infected with COVID-19 is usually normal.
- Some patients report abdominal pain.[19]
Back
- Back examination of patients infected with coronavirus is usually normal.
Genitourinary
- Genitourinary examination of patients infected with coronavirus is usually normal.
Neuromuscular
- Neuromuscular examination of patients infected with coronavirus shows:
- Cranial Nerve 1 or Olfactory nerve should be examined to evaluate for anosmia. Studies suggests that anosmia can be an important clue, heping the diagnosis of COVID-19 specially in the early stages.[20] According to a study published anosmia and aguesia to be strong predictors of COVID-1 infection.[21]
Extremities
- Extremities examination of patients infected with coronavirus is usually normal.
