Presentation
The disease presents as severe respiratory infection often with shock, acute kidney injury, and coagulopathy. Recently, we observed three cases who presented with neurologic symptoms. [ncbi.nlm.nih.gov]
Affected patients typically present with fever, chills, rigors, headache, a nonproductive cough, dyspnea, and myalgia. [ajronline.org]
Entire Body System
- Fever
OR Close contact 2 with a confirmed or probable case of MERS while the case was ill AND fever (>100°F) or symptoms of respiratory illness within 14 days following the close contact. (This is a lower threshold than category A.) [web.archive.org]
The first patient developed respiratory symptoms and fever 14 days after admission to hospital for an unrelated reason. He died 11 days later with multi-organ failure. [ncbi.nlm.nih.gov]
[…] or symptoms of respiratory infection; - If developing symptoms such as fever or cough, put on a mask and consult a doctor immediately. [ift.edu.mo]
To diagnose MERS, a doctor will perform a physical examination and check for fever and swollen glands. He or she will also listen to your lungs with a stethoscope. [medbroadcast.com]
Symptoms of Mers infection include fever, cough, shortness of breath and breathing difficulties. Severe complications include pneumonia and kidney failure. [asiaone.com]
- Hypoxemia
One patient required extracorporeal membrane oxygenation to treat refractory hypoxemia, and one patient died of shock with multiorgan failure. All the patients had fever, myalgia, leucopenia, normal procalcitonin level, and pneumonia. [ncbi.nlm.nih.gov]
Until more data are available, ECMO could be considered as a rescue therapy in selected MERS-CoV patients with refractory hypoxemia. [doi.org]

Respiratoric
- Dry Cough
The patient was 44 years old and had symptoms including high fever, dry cough with a little phlegm, and shortness of breath, which are roughly consistent with those associated with MERS, and had had close contact with individuals with confirmed cases [ncbi.nlm.nih.gov]

The main symptoms are a fever, a dry cough, shortness of breath, or trouble breathing. MERS may also cause a headache, muscle aches, a sore throat, fatigue, and diarrhea or there may be no symptoms at all. [healthlinkbc.ca]

Gastrointestinal
- Diarrhea
Upon arrival, he complained of diarrhea and weakness, but denied any respiratory symptoms, and he directly went to visit an emergency room. [ncbi.nlm.nih.gov]
Other symptoms may include nausea, vomiting and diarrhea. Pneumonia is common, and sometimes it may cause injury to organs, such as the kidneys. Some people only have mild symptoms. [health.utah.gov]
Middle East respiratory syndrome ( MERS ), also known as camel flu, is a viral respiratory infection caused by the MERS-coronavirus (MERS-CoV).Symptoms may range from mild to severe.They include fever, cough, diarrhea, and shortness of breath .Disease [dimsumdaily.hk]
- Nausea
Other symptoms may include nausea, vomiting and diarrhea. Pneumonia is common, and sometimes it may cause injury to organs, such as the kidneys. Some people only have mild symptoms. [health.utah.gov]
Most people with MERS-CoV infection have had severe acute respiratory illness with symptoms of: Fever Cough Shortness of breath Pneumonia Other symptoms may include chils, diarrhea, nausea, vomiting. [sfcdcp.org]
Other symptoms may include nausea, vomiting and diarrhea. Pneumonia is common, and sometimes it may cause injury to organs, such as the kidneys. [wisehealthsystem.com]
In some cases, gastrointestinal symptoms including diarrhea and nausea/vomiting have been reported. [health.govt.nz]
Others reported having gastrointestinal symptoms, like diarrhea and nausea/vomiting, and kidney failure. MERS can even be deadly. Many people have died. [cdc.gov]
Cardiovascular
- Vascular Disease
Evidence of chronic disease, including severe peripheral vascular disease, patchy cardiac fibrosis, and hepatic steatosis, was noted in the other organs. [ncbi.nlm.nih.gov]
Workup
X-Ray
- Air Bronchogram
An air bronchogram is sometimes seen within areas of consolidation (11% of cases). Less common radiographic findings include irregular linear-type airspace disease (9% of cases) ( Fig. 3 ) and multicentric cavitation (2% of cases) [ 11 ] ( Fig. 4 ). [ajronline.org]
- Left Pleural Effusion
Left lung shows moderate-sized pleural effusion with airspace consolidation. This patient was health care worker and completely recovered despite pleural effusion. [ajronline.org]
Serum
- Lymphopenia
All 3 patients had fever, cough, shortness of breath, bilateral infiltrates on chest x-ray, thrombocytopenia, lymphopenia and rises in serum creatinine kinase and alanine transaminase. [ncbi.nlm.nih.gov]
Treatment
Currently, there is no proven effective treatment. The new findings show that a combination of interferon-alpha 2b and ribavirin, drugs routinely used to treat hepatitis C, may be an effective treatment for MERS-CoV infection, said Dr. Angela L. [washington.edu]
Combination therapy with interferon-α2b and ribavirin has been used successfully as primary treatment and prophylaxis in SARS. [ncbi.nlm.nih.gov]
Treatment No vaccine or specific treatment is currently available. Treatment is supportive in hospital and intensive care facilities may be needed. Prevention in Travellers The risk to travellers to the Middle East is very low. [fitfortravel.nhs.uk]
Treatment There is no specific antiviral treatment recommended for MERS-CoV infection. Individuals with MERS often receive medical care to help relieve symptoms. For severe cases, current treatment includes care to support vital organ functions. [cdc.gov]
Prognosis
A shorter incubation period was associated with more severe disease and greater risk of mortality, and the severity of fever predicted the prognosis of MERS-CoV infection-related pneumonia. [ncbi.nlm.nih.gov]
This understanding, in turn, should improve the assessment of lung abnormalities based on chest radiographic and CT scores and allow clinicians to accurately monitor disease progression and provide more accurate information regarding patient prognosis [ajronline.org]

Pathophysiology
CNS involvement should be considered in patients with MERS-CoV and progressive neurological disease, and further elucidation of the pathophysiology of this virus is needed. [ncbi.nlm.nih.gov]
The underlying pathophysiology of MERS-CoV is not fully understood. However, it is thought that MERS-CoV may be primarily zoonotic in nature, although human-to-human transmission is limited (but possible). [ajronline.org]
Prevention
Control and Prevention Middle East respiratory syndrome coronavirus (MERS-CoV) —The World Health Organization [professionals.site.apic.org]
Prevention Currently, there is no vaccine to prevent MERS-CoV infection. The U.S. National Institutes of Health is exploring the possibility of developing one. [cdc.gov]
Prevention : There is no vaccine for MERS so prevention is critical. [phc.amedd.army.mil]
Some of this information may be applicable to control and prevention of MERS-CoV infections. [osha.gov]
No specific drug treatment exists for MERS and infection prevention and control measures are crucial to prevent spread in health-care facilities. MERS-CoV continues to be an endemic, low-level public health threat. [ncbi.nlm.nih.gov]
