Middle East Respiratory Syndrome (MERS): Symptoms, Causes, Treatment

What are the symptoms of Middle East respiratory syndrome?

Middle East Respiratory Syndrome (MERS) is a viral respiratory illness that is caused by the MERS-CoV virus. The symptoms of MERS can range from mild to severe and may include:

1. Fever: A high fever, usually above 38°C (100.4°F), is a common symptom of MERS.
2. Cough: A cough is a frequent symptom of MERS, and it can be dry or productive of mucus.
3. Shortness of breath: Shortness of breath or difficulty breathing is a common symptom of MERS, and it can be severe in some cases.
4. Chills: Some people with MERS may experience chills, which are a feeling of coldness or shivering.
5. Fatigue: Fatigue or feeling tired is a common symptom of MERS.
6. Headache: A headache is a common symptom of MERS, and it can be severe in some cases.
7. Muscle pain: Muscle pain or weakness is a common symptom of MERS.
8. Sore throat: A sore throat is a common symptom of MERS, and it can be accompanied by a cough.
9. Runny nose: A runny nose or congestion is a common symptom of MERS.
10. Diarrhea: Diarrhea is a common symptom of MERS, and it can be severe in some cases.

In severe cases, MERS can cause more serious symptoms, such as:

1. Respiratory failure: In severe cases, MERS can cause respiratory failure, which requires mechanical ventilation to support breathing.
2. Pneumonia: Pneumonia is a complication that can occur in people with MERS, especially in those who are older or have underlying health conditions.
3. Acute respiratory distress syndrome (ARDS): ARDS is a life-threatening condition that occurs when the lungs become inflamed and fill with fluid, making it difficult for the body to get enough oxygen.

It’s important to note that not everyone with MERS will experience all of these symptoms, and the severity of the symptoms can vary widely from person to person. If you suspect you have been exposed to MERS or are experiencing symptoms, it’s essential to seek medical attention immediately.

What are the causes of Middle East respiratory syndrome?

Middle East Respiratory Syndrome (MERS) is a viral respiratory illness caused by the MERS-CoV virus. The virus is a member of the coronaviruses family and is believed to have originated from bats. The exact mechanism of transmission from bats to humans is not yet fully understood, but it is thought to occur through an intermediate animal host.

The primary source of MERS-CoV is camels, which are infected with the virus and can shed it in their saliva, urine, and other bodily fluids. Human-to-human transmission has also been reported, primarily in healthcare settings, where close contact with infected patients or contaminated surfaces can occur.

The risk factors for MERS include:

1. Exposure to camels: People who have been in contact with camels, such as camel handlers, farmers, or people who consume camel products, are at higher risk of contracting MERS.
2. Travel to affected areas: Traveling to countries where MERS has been reported, such as Saudi Arabia, the United Arab Emirates, Qatar, and Oman, increases the risk of exposure.
3. Close contact with infected individuals: People who have been in close contact with individuals who have MERS, such as healthcare workers or family members, are at higher risk of infection.
4. Weakened immune system: People with weakened immune systems, such as those with chronic illnesses or taking immunosuppressive therapy, are at higher risk of severe illness and death from MERS.

The exact mechanisms of transmission are still being studied, but it is believed that the virus is primarily spread through:

1. Direct contact: Direct contact with infected animals or contaminated surfaces.
2. Indirect contact: Indirect contact with infected animals or contaminated surfaces through contaminated air, water, or food.
3. Human-to-human transmission: Human-to-human transmission through close contact with infected individuals or contaminated surfaces.

It’s essential to take precautions to prevent the spread of MERS-CoV, especially in healthcare settings and among people who have been in close contact with infected individuals or animals.

How is the diagnosis of Middle East respiratory syndrome made?

The diagnosis of Middle East Respiratory Syndrome (MERS) is typically made through a combination of clinical evaluation, laboratory tests, and radiological imaging. The diagnostic process usually involves the following steps:

1. Clinical evaluation: A healthcare provider will conduct a thorough medical history and physical examination to assess the patient’s symptoms and overall health.
2. Laboratory tests: Laboratory tests are used to confirm the presence of MERS-CoV in the patient’s body. These tests may include:
   • Real-time reverse transcription polymerase chain reaction (rRT-PCR): This test detects the genetic material of MERS-CoV in respiratory secretions, such as saliva or sputum.
   • Serology: This test detects the presence of antibodies against MERS-CoV in the patient’s blood.
   • Blood culture: This test is used to rule out other bacterial infections that may cause similar symptoms.
3. Radiological imaging: Radiological imaging tests, such as chest X-rays or computed tomography (CT) scans, are used to evaluate the extent of lung involvement and detect any signs of pneumonia or other complications.
4. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing: In some cases, SARS-CoV-2 testing may be performed to rule out COVID-19 infection.

A diagnosis of MERS is typically made based on a combination of the following criteria:

1. Clinical presentation: The patient must have symptoms consistent with MERS, such as fever, cough, and shortness of breath.
2. Laboratory results: The patient must have laboratory evidence of MERS-CoV infection, such as positive PCR or serology results.
3. Radiological findings: The patient must have radiological evidence of lung involvement, such as infiltrates or consolidation on chest X-ray or CT scan.

A definitive diagnosis of MERS can only be made by a healthcare provider who has experience in diagnosing and managing infectious diseases.

What is the treatment for Middle East respiratory syndrome?

There is no specific treatment for Middle East Respiratory Syndrome (MERS), but the main goal of treatment is to manage symptoms and support the patient’s breathing and overall health. The treatment approach typically includes:

1. Supportive care: Patients with MERS receive supportive care, including:
   • Oxygen therapy: Oxygen supplementation to help improve oxygen levels in the blood.
   • Mechanical ventilation: Mechanical ventilation may be necessary in severe cases to support breathing.
   • Fluid management: Fluid management is crucial to prevent dehydration and maintain proper fluid balance.
   • Pain management: Pain management is important to reduce discomfort and improve quality of life.
2. Antiviral medications: Antiviral medications may be prescribed to help reduce the severity of symptoms and duration of illness, but their effectiveness is still being studied.
3. Corticosteroids: Corticosteroids may be used to reduce inflammation in the lungs and improve lung function.
4. Vasopressors: Vasopressors may be used to support blood pressure and circulation.
5. Cardiovascular support: Cardiovascular support may be necessary in some cases, including the use of pacemakers or implantable cardioverter-defibrillators.

It’s essential to note that MERS-CoV is a rapidly evolving virus, and treatment approaches are still being refined. Patients with MERS should be treated in a hospital setting by healthcare professionals experienced in managing infectious diseases.

In addition to medical treatment, public health measures are crucial to prevent the spread of MERS-CoV. These measures include:

1. Isolation: Isolation of patients with MERS-CoV infection to prevent transmission to others.
2. Contact tracing: Contact tracing to identify and monitor individuals who have been in close contact with patients with MERS-CoV infection.
3. Personal protective equipment (PPE): Use of PPE, such as masks, gloves, and gowns, by healthcare workers caring for patients with MERS-CoV infection.
4. Environmental cleaning and disinfection: Environmental cleaning and disinfection of surfaces and equipment to prevent transmission.

It’s essential to work closely with healthcare professionals and follow recommended guidelines to prevent the spread of MERS-CoV.
