Summary
Middle Eastern Respiratory Syndrome Coronavirus (MERS-CoV) caused 206 deaths by March 2014, with a 42% mortality rate. Human infections likely stem from camels, with limited human-to-human spread observed.
Area of Science:
- Infectious Diseases
- Virology
- Public Health
Background:
- Middle Eastern Respiratory Syndrome Coronavirus (MERS-CoV) emerged in 2012.
- Associated with significant mortality (42% as of March 2014).
- Primarily linked to camel exposure, with limited human-to-human transmission.
Purpose of the Study:
- To summarize the epidemiology and clinical features of MERS-CoV.
- To highlight transmission routes and patient demographics.
- To review current treatment outcomes.
Main Methods:
- Review of reported MERS-CoV cases.
- Analysis of epidemiological data.
- Clinical case descriptions.
Main Results:
- 206 deaths reported by March 2014.
- Predominant origin of cases in the Middle East (Saudi Arabia).
- Typical symptoms include fever, chills, and acute respiratory distress syndrome; gastrointestinal symptoms less common.
- Older males with comorbidities represent the majority of severe cases.
- Undetected minimally symptomatic cases are likely.
- No effective therapies identified; supportive care is standard.
Conclusions:
- MERS-CoV poses a significant public health threat.
- Camel-to-human transmission is the primary route.
- Further research into effective treatments is crucial.
- Ongoing surveillance is necessary to monitor MERS-CoV spread.

Respiratory disorders, a prevalent health concern globally, are generally divided into two primary categories: upper and lower respiratory tract disorders. The categorization is based on the area of the respiratory system they affect.
Upper respiratory disorders impact the airways above the vocal cords, encompassing areas like the nose, sinuses, and throat. Various conditions fall under this category, including the common cold and allergic rhinitis. These disorders can stem from several causes,...

The treatment for acute respiratory failure varies based on factors like the underlying cause, overall health, and severity. A collaborative healthcare team is essential for early detection, often through arterial blood gas analysis. Identifying the cause is the primary goal, with treatment strategies adjusted for ventilation/perfusion (V/Q) mismatch, shunting, or diffusion impairment.

Acute respiratory failure is a condition characterized by the inability of the lungs to perform their primary function: gas exchange. This failure leads to insufficient oxygen levels (hypoxemia) in the blood, elevated carbon dioxide levels (hypercapnia), or both, causing critical impairment in organ function.
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...

Type I Respiratory Failure, or hypoxemic respiratory failure, occurs when the partial pressure of oxygen (PaO2) in arterial blood falls below 60 mmHg while breathing room air without a corresponding increase in arterial carbon dioxide levels (PaCO2). This condition highlights a significant impairment in the lungs' capacity to oxygenate the blood.
The underlying physiological abnormalities that contribute to hypoxemic respiratory failure include:

Hypercapnic respiratory failure, also known as Type 2 or ventilatory respiratory failure, is a severe condition characterized by the body's inability to effectively remove carbon dioxide (CO2) from the bloodstream. It leads to an arterial CO2 pressure (PaCO2) exceeding 45 mmHg and a blood pH above 7.35. This situation indicates that the body's ventilatory demand, or the ventilation needed to maintain normal PaCO2 levels, surpasses its supply or the maximum gas flow achievable without...

Respiratory failure can manifest suddenly or gradually, characterized by a rapid decline in PaO2 and a rapid rise in PaCO2. This situation indicates a severe respiratory problem that may quickly become a life-threatening emergency. One of the early signs of hypoxemic Acute Respiratory Failure (ARF) is a change in mental status due to the brain's sensitivity to oxygen levels and changes in acid-base balance. Symptoms such as restlessness, confusion, and agitation suggest inadequate oxygen...
