Severe Acute Respiratory Syndrome (SARS) Description

SARS is a serious and potentially life-threatening respiratory illness caused by the SARS-associated coronavirus (SARS-CoV). The symptoms of SARS are similar to those of other common respiratory viral infections, but are more severe.

• Initial Symptoms: SARS usually begins with flu-like signs and symptoms, including fever, chills, muscle aches, headache, and occasionally diarrhea [1].
• Progression of Symptoms: After about a week, the symptoms can progress to include high fever, cough, shortness of breath, and in severe cases, pneumonia [2][6].
• Respiratory Distress: Infection with the SARS virus can cause acute respiratory distress, which can lead to serious complications if left untreated [5].

Key Facts

• SARS is a viral respiratory illness caused by a coronavirus.
• Symptoms appear after 3 to 10 days and include fever, headache, chills, muscle aches, cough, and shortness of breath.
• SARS can lead to pneumonia, which can be life-threatening if not treated promptly.

Severe Acute Respiratory Syndrome (SARS) Signs and Symptoms

SARS, a viral disease caused by a SARS-associated coronavirus, can manifest in various ways. The symptoms typically begin with flu-like signs and progress to more severe respiratory issues.

• Initial Symptoms: Fever, chills, muscle aches, headache, and occasionally diarrhea are common initial symptoms of SARS.
• Progressive Symptoms: After about a week, the following symptoms become apparent:
  • Fever of 100.5 F (38 C) or higher
  • Dry cough
  • Shortness of breath

It's essential to note that SARS can be challenging to recognize in children as it may mimic other respiratory diseases like influenza.

• Additional Symptoms: Some individuals may experience additional symptoms, including:
  • Headache
  • Chills and rigors (shivering)
  • General feeling of discomfort
  • Body aches

These symptoms are based on information from various sources [1-8].

Diagnostic Tests for Severe Acute Respiratory Syndrome (SARS)

There are several diagnostic tests available to detect SARS-CoV-2, the virus that causes COVID-19.

• Molecular Diagnostic Tests: These tests detect the genetic material of the virus and include:
  • Real-time PCR (Polymerase Chain Reaction) tests [7]
  • Nucleic acid extraction procedures involving untreated specimens [4]
• Antigen Diagnostic Tests: These tests detect specific proteins on the surface of the virus, such as:
  • Rapid antigen tests that can quickly detect fragments of proteins found on or within the virus [9]
• Serological Tests: These tests detect antibodies produced by the body in response to infection, such as:
  • Serological tests for SARS-CoV-2 [7]

Types of Diagnostic Tests

There are two main categories of testing to diagnose SARS-CoV-2:

1. Real-time PCR (RT-PCR): This test identifies viral RNA and is commonly used to detect the virus in respiratory specimens.
2. Serological tests: These tests detect antibodies produced by the body in response to infection.

Authorized Diagnostic Tests

The following diagnostic tests have been authorized for emergency use:

• Molecular diagnostic tests [1]
• Antigen diagnostic tests that have been authorized individually [3]

Current Status of Drug Treatment for Severe Acute Respiratory Syndrome (SARS)

The search results indicate that there is no specific antiviral treatment available for SARS, and the best treatment strategy remains unknown [4]. However, several laboratory tests can help detect the virus [1].

Existing Treatments

Some existing drugs have been used to treat SARS, including:

• Ribavirin: This antiviral medication was used extensively during the SARS outbreak [3].
• Corticosteroids: These were also used to reduce inflammation and swelling in the lungs [3].
• Lopinavir/ritonavir: A combination of these two medications has been investigated as a potential treatment for SARS, but its effectiveness is still unclear [9].

Current Research

Research is currently underway to develop an effective antiviral drug for SARS-CoV. However, until then, people with SARS may receive mainly supportive therapy, including oxygen and fluids to help ease symptoms [5]. Remdesivir has been recently indicated for the treatment of COVID-19, but its effectiveness in treating SARS is still unknown [2].

Challenges

The development of an effective antiviral drug for SARS is a significant challenge. The virus has shown resistance to various treatments, and there is currently no established treatment specifically for SARS [13]. As a result, the best course of treatment often depends on the individual's symptoms and overall health.

Differential Diagnosis of Severe Acute Respiratory Syndrome (SARS)

Severe Acute Respiratory Syndrome (SARS) is a life-threatening illness caused by the SARS-CoV2 virus. When diagnosing SARS, it's essential to consider various differential diagnoses that can present with similar symptoms.

Possible Differential Diagnoses:

• Bacterial Pneumonia: Bacterial pneumonia can cause severe respiratory symptoms, including cough, fever, and difficulty breathing (1).
• Multisystem Organ Failure: Multisystem organ failure can occur in SARS patients, leading to complications such as acute respiratory distress syndrome (ARDS), sepsis, and septic shock (2).
• Acute Respiratory Distress Syndrome (ARDS): ARDS is a severe form of lung injury that can be caused by various factors, including viral infections like SARS-CoV2 (10).
• Influenza: Influenza can cause severe respiratory symptoms, including pneumonia and acute respiratory failure (not explicitly mentioned in the context but relevant to differential diagnosis).

Key Diagnostic Features:

When diagnosing SARS, healthcare providers should look for key features such as:

• Severe respiratory symptoms, including cough, fever, and difficulty breathing
• Radiographic evidence of pneumonia or lung injury
• Multisystem organ failure, including ARDS, sepsis, and septic shock
