In the last two years of the pandemic, the number of infected cases of coronavirus has risen dramatically. Given its current trajectory and how it is mutating, the virus has proven to be a challenge to contain.

Initially, when the first reports of the spread of the virus had started pouring in from China, it was being called the '2019 novel coronavirus'. The virus was termed as such, considering its nature and the fact that a virus of such characteristic had not been detected before.

Incidentally, both COVID-19 and SARS emanate from a coronavirus. The virus that causes SARS is termed SARS-CoV. On the other hand, the virus that causes COVID-19 is termed SARS-CoV-2.

Let us understand the Difference between Coronavirus SARS-Cov 2 and COVID-19.

What Is Coronavirus?

Coronaviruses belong to a family of viruses that thrive on an extensive range of hosts. Most of the coronaviruses are observed in bats but they can also reside in humans. A closer study of a coronavirus shows that it has several spike-like projections on its surface which can often look like a crown.

A new type of coronavirus can emerge when a virus develops the ability to transfer from an animal to a human.

What Is SARS?

SARS is a type of respiratory disease that one can get from a SARS-CoV. SARS stands for Severe Acute Respiratory Syndrome. The most common origin of the SARS virus is thought to be bats. One of the first symptoms of SARS-CoV is fever, but it may be accompanied by several other symptoms such as cough, body aches, and pains.

What Makes COVID-19 Different from SARS?

There are multiple points of Difference between Coronavirus SARS-Cov 2 and COVID-19. The following pointers highlight how they are different:

BASISCOVID-19SARS-CoV
SymptomsThe common symptoms of COVID-19 are fever, cough, fatigue, shortness of breath, muscle aches, pains, headaches, and diarrhoea.However, SARS may exhibit only fever, cough, malaise, body aches, pains, and headaches.
SeverityCases of COVID-19 are thought to be milder than SARS. Only 20% of those affected require mechanical ventilation.Out of the affected, almost 30% of the patients can require mechanical ventilation.
TransmissionTransmission of COVID-19 occurs more easily than SARS. This could be due to the development of enough viral load which occurs shortly after a person is infected with COVID-19.SARS is not transmitted as easily as COVID-19.
Incubation Period4 to 5 days5 days
Mortality Rate4.6%10.8%
R01.4 - 2.53
Male to Female ratio2.7:11:1.25

COVID-19 and SARS are caused due to coronaviruses that originate in animals before transmitting to humans. While the two viruses have many similarities, they are quite different from each other in terms of their symptoms.

FAQs on Difference between Coronavirus SARS-Cov 2 and COVID-19

Q.1. What Difference between Coronavirus SARS-Cov 2 and COVID-19 indicates that one spreads wider than the other?

Cases of SARS were contained meticulously through early detection and social distancing but in the case of COVID-19, detection of the virus is trickier. Those infected, tend to shed their viral load much before they develop visible symptoms of the infection, which further makes it difficult to contain the virus. This indicates the Difference between Coronavirus SARS-Cov 2 and COVID-19 in terms of proliferation.

Q.2. Explain the concept of receptor binding in the case of SARS and COVID-19 considering the Difference between Coronavirus SARS-Cov 2 and COVID-19.

Receptor binding is the event that describes how the spike protein on the virus is attached to the cells in the host body. Despite the Difference between Coronavirus SARS-Cov 2 and COVID-19, both use the same host cell receptor.

Q.3. How does the Difference between Coronavirus SARS-Cov 2 and COVID-19 impact the mortality rates in either case?

The location and characteristics of the population significantly affect the rate of mortality. Although the rates differ from one country to another, the average rate of mortality for the disease lies between 0.25 and 3, this is how the Difference between Coronavirus SARS-Cov 2 and COVID-19 impact the mortality rates.

Q.4. In spite of the Difference between Coronavirus SARS-Cov 2 and COVID-19, mention some ways in which SARS and COVID-19 are similar.

Despite the Difference between Coronavirus SARS-Cov 2 and COVID-19, both diseases are respiratory problems that are caused by coronaviruses and show similar stability on surfaces and air. Most of their symptoms are also similar and they can attack at-risk groups with underlying health problems.
