Background
- The current national and international pandemic is from a virus named SARS-CoV-2 (previously 2019-nCoV), which causes a disease named COVID-19.
- Also known as "2019 Novel Coronavirus"
- First detected in Wuhan, China
Clinical Features
Broad Testing Recommendations
The CDC has expanded testing beyond the initial travel to china recommendations[1]
- Test any person who has fever or respiratory illness AND had close contact with a known COVID-19 patient
- Test any person who has fever or respiratory illness AND a history of travel to CDC-classified high risk areas or areas with recent significant community spread
- Test any person who has severe respiratory illness AND is being admitted to the hospital
- Test any hospitalized person who has respiratory illness AND no alternative diagnosis
- Consider testing any person who has respiratory illness AND lives in a residential facility such as a nursing home or recently returned from a cruise
Differential Diagnosis
Influenza-Like Illness
- Influenza
- Parainfluenza
- URI
- Pneumonia
- Sinusitis
- Toxic exposure
- Pyelonephritis
- Bronchitis
- Coronavirus
Causes of Pneumonia
Bacteria
Viral
- Common
- Influenza
- Respiratory syncytial virus
- Parainfluenza
- Rarer
- Adenovirus
- Metapneumovirus
- Severe acute respiratory syndrome (SARS)
- Middle east respiratory syndrome coronavirus (MERS)
- 2019-nCoV (COVID-19)
- Cause other diseases, but sometimes cause pneumonia
Fungal
- Histoplasmosis
- Coccidioidomycosis
- Blastomycosis
- Pneumocystis jirovecii pneumonia (PCP)
- Sporotrichosis
- Cryptococcosis
- Aspergillosis
- Candidiasis
Parasitic
Evaluation
Patient rooming
- Evaluation of patients does not need to occur in the hospital and can easily occur outside the ED if the patient is not in extremis
- Although negative pressure rooms are preferred due to the droplet precautions, a non-negative pressure room is acceptable
Viral Test
- In the United States, the US Centers for Disease Control is distributing the CDC 2019-Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel to public health labs through its International Reagent Resource[2]
- Internationally the WHO has distributed kits based on the RT-PCR platform[3]
- BIOFIRE RESP PANEL Corona Virus assay does NOT detect this subtype - DO NOT USE
Management
Personal Protective Equipment
Clinical Assessment
PPE for evaluating a patient clinically should include:
- N95
- Face mask
- Surgical Gown and gloves
- The video below indicates the proper order for donning and doffing PPE for clinical evaluation of a patient
During Intubation
- N95 or PAPR
- Surgical Mask over N95
- Goggles that surround eyes with facial contact, face shield, or full joint-replacement-hood with visor
- Bunny suit, preferably with hood or disposable fluid-proof gown
- If no hooded suit available, sterile disposable cap
- 2 pairs gloves, 1 under sleeves of bunny suit or gown and 1 over, under-layer gloves would ideally be long cuffed
Mild Cases
- Supportive care is mainstay of therapy for patients with mild viral symptoms
- Most patients will do well enough for discharge home
- Discuss with Dept of Public Health, who will guide testing and, if discharging, help patient remain in isolation at home
Respiratory failure
- NIPPV may increase the spread of viral particles via droplets making early intubation the preferred airway management strategy in patients with respiratory distress/failure
- Using 2 viral filters attached to a 2 tube NIPPV circuit in a negative pressure room may sufficiently prevent viral spread
- During BVM, if needed, use a viral filter
- Due to the viral spread risk early intubation is the preferred means of airway managment
Disposition
- Mild cases for perons under investigation for Covid19 awaiting a positive test result can self quarantine at home in conjunction with the local Public Health Dept
- If admitting, needs to be placed in negative pressure isolation room with airborne and droplet precautions
