Why Severe Acute Respiratory Syndrome (SARS) is So Dangerous

Severe Acute Respiratory Syndrome (SARS) is a highly infectious respiratory disease that first emerged in Guangdong Province, China in November 2002. The disease spread rapidly throughout the world in 2003, causing widespread panic and fear. SARS is caused by the SARS coronavirus (SARS-CoV), which is a type of coronavirus that has caused other serious outbreaks in the past, including the COVID-19 pandemic. In this blog post, we will explore why SARS is so dangerous and how it can cause severe illness.

The Contagiousness of SARS

SARS is a highly contagious disease that is considered one of the most dangerous in the world. The virus is transmitted through respiratory droplets, which makes it easy to spread from person to person. This is a major concern in places where people are in close proximity, such as hospitals, schools, and public transportation systems. The virus can survive on surfaces for a prolonged period of time, which means that it can easily be transmitted through contact with contaminated objects.

The highly contagious nature of SARS is due to several factors. For example, the virus can be transmitted even before symptoms appear, making it difficult to identify and contain. In addition, the virus can mutate quickly, which makes it difficult to develop effective treatments and vaccines. Furthermore, the virus can cause a wide range of symptoms, from mild to severe, which makes it difficult to diagnose and treat.

Given the high contagiousness of SARS, it is important to take steps to prevent its spread. These steps include frequent hand washing, avoiding close contact with infected individuals, wearing masks in public settings, and disinfecting surfaces regularly. In addition, healthcare professionals must be vigilant in identifying and containing outbreaks of the disease in order to prevent its spread to the wider population..

Severe Symptoms

Patients with SARS can experience a wide range of symptoms, from mild to severe. The disease typically starts with flu-like symptoms such as fever, headache, and body aches, but it can quickly progress to severe respiratory distress. Many patients develop pneumonia, which can lead to acute respiratory distress syndrome (ARDS) and respiratory failure.

In addition to the symptoms mentioned above, some patients with SARS also experience gastrointestinal symptoms such as diarrhea and vomiting. This can further complicate the disease and make it difficult for patients to recover.

Furthermore, SARS can also have long-term effects on a patient’s health. Studies have shown that some patients continue to experience fatigue, muscle weakness, and joint pain even after they have recovered from the acute phase of the illness. These long-term effects can significantly impact a patient’s quality of life and ability to function normally, even after they have been discharged from the hospital.

It is important to note that the severity of the symptoms can vary depending on the patient’s age, immune system, and overall health. While some patients may only experience mild symptoms, others can quickly deteriorate and require intensive care. Therefore, it is crucial for healthcare providers to closely monitor and manage patients with SARS in order to provide the best possible care and outcomes.

Lack of Treatment

One of the most concerning aspects of SARS is the lack of specific treatment for the disease. While supportive care can be provided to help manage symptoms, there is no cure for SARS. This means that patients who develop severe illness may not be able to recover, especially if they do not receive prompt and appropriate medical care.

Furthermore, the lack of a specific treatment for SARS has resulted in a serious public health concern, as the disease can spread rapidly and potentially lead to large-scale outbreaks. As a result, there is an urgent need to identify effective treatments and vaccines to prevent and control the spread of SARS.

In recent years, researchers have made significant progress in understanding the molecular mechanisms underlying SARS and other coronaviruses. This has led to the identification of several potential targets for antiviral therapy, including viral protease inhibitors, RNA synthesis inhibitors, and other small molecule compounds.

‘Despite these advances, the development of effective treatments and vaccines for SARS remains a challenging task.”

This is due in part to the complex nature of the virus and the difficulty in predicting its behavior. However, ongoing research efforts are focused on developing new strategies and therapies to combat SARS and other emerging infectious diseases.


Severe Acute Respiratory Syndrome (SARS) is a highly contagious respiratory disease that can cause severe illness and even death. The disease is dangerous because it is highly contagious, can cause severe symptoms, and there is no specific treatment or vaccine available. While SARS is no longer a major public health threat, it is important to remember the lessons learned from the outbreak in 2003 to help prevent future outbreaks of similar diseases. We must remain vigilant and take measures to prevent the spread of infectious diseases, both now and in the future.
