Why Is It Called COVID-19? Unveiling the Name's Origin

COVID-19 is called COVID-19 because it stands for Coronavirus Disease discovered in 2019, as explained by WHO. At WHY.EDU.VN, we break down the etymology, the naming conventions, and the roles of organizations like the WHO and ICTV in this crucial process. Discover the connection between disease nomenclature, viral taxonomy, and the importance of accurate communication in this complete guide.

1. Understanding the COVID-19 Name: A Comprehensive Explanation

COVID-19 is the name given to the disease caused by the virus SARS-CoV-2. The World Health Organization (WHO) officially named it on February 11, 2020. Let’s dig into why it received this specific name, and the naming conventions involved.

1.1. What Does COVID-19 Stand For?

The acronym “COVID-19” breaks down as follows:

CO stands for Corona
VI stands for Virus
D stands for Disease
19 represents the year the disease was first identified (2019)

This naming convention helps provide a clear and concise identifier for the disease, facilitating communication among healthcare professionals, researchers, and the public.

1.2. The Distinction Between Virus and Disease Names

It’s important to recognize that the virus and the disease it causes often have different names. This distinction serves specific purposes in virology and public health.

Virus Names: These are based on the virus’s genetic structure. This is crucial for developing diagnostic tests, vaccines, and medications. The International Committee on Taxonomy of Viruses (ICTV) is responsible for naming viruses.
Disease Names: These names are designed to enable discussion around disease prevention, spread, transmissibility, severity, and treatment. The WHO officially names diseases in the International Classification of Diseases (ICD).

For example, HIV is the virus that causes AIDS. People commonly know the disease name (AIDS) but may not know the name of the virus (HIV).

1.3. The Naming of SARS-CoV-2

On February 11, 2020, the ICTV announced that the new virus would be named “Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2).” This name was chosen because the virus is genetically related to the coronavirus responsible for the SARS outbreak in 2003.

While related, the two viruses are distinct. The naming reflects the genetic similarity while acknowledging the differences in their characteristics and impacts.

1.4. WHO’s Role in Naming COVID-19

The WHO officially named the disease “COVID-19” on the same day, February 11, 2020. This naming followed guidelines previously developed with the World Organisation for Animal Health (OIE) and the Food and Agriculture Organization of the United Nations (FAO).

The collaboration between these organizations ensures a standardized and coordinated approach to naming diseases, which is crucial for global health communication and response efforts.

2. The Importance of Clear and Accurate Naming

Naming viruses and diseases accurately and clearly is essential for several reasons.

2.1. Facilitating Scientific Research

Accurate naming enables researchers to track and study viruses and diseases effectively. Standardized names help in:

Data Analysis: Researchers can aggregate and analyze data from different sources to understand the characteristics and behavior of the virus or disease.
Collaboration: Clear naming facilitates collaboration among scientists worldwide, ensuring everyone is referring to the same entity.
Development of Countermeasures: Consistent naming helps in the development of diagnostic tests, vaccines, and treatments.

2.2. Enhancing Public Health Communication

Clear and accurate naming is vital for effective public health communication. It helps:

Inform the Public: The public needs to understand what a disease is called to stay informed about health risks and preventive measures.
Reduce Confusion: Standardized names minimize confusion and ensure everyone is on the same page.
Implement Public Health Strategies: Governments and health organizations can effectively implement public health strategies when the disease is clearly identified.

2.3. Avoiding Unnecessary Fear

The WHO considered the potential for “unnecessary fear” when deciding how to refer to the virus in public communications.

Using the name “SARS” might have triggered anxiety, especially in regions severely affected by the 2003 SARS outbreak. Therefore, the WHO often refers to the virus as “the virus responsible for COVID-19” or “the COVID-19 virus” in public communications.

These designations are not intended to replace the official name of the virus, as agreed upon by the ICTV, but rather to communicate effectively with the public without causing undue alarm.

3. WHO and ICTV: Roles and Responsibilities

The WHO and ICTV play distinct but complementary roles in naming viruses and diseases.

4. Detailed Look at the Virus: SARS-CoV-2

SARS-CoV-2 is a Betacoronavirus, belonging to the same family of viruses as SARS-CoV. Understanding its genetic structure and behavior is crucial for developing effective countermeasures.

4.1. Genetic Structure and Evolution

SARS-CoV-2 is an RNA virus, meaning its genetic material is composed of ribonucleic acid (RNA). The virus’s genome consists of approximately 30,000 nucleotides, which encode for various proteins essential for its replication and infection.

Spike Protein: This protein is located on the surface of the virus and is responsible for binding to host cells, allowing the virus to enter and infect them.
Replication: Like other RNA viruses, SARS-CoV-2 has a relatively high mutation rate, which means it can evolve rapidly. This rapid evolution can lead to the emergence of new variants that may be more transmissible or resistant to vaccines and treatments.

4.2. Transmission and Infection

SARS-CoV-2 primarily spreads through respiratory droplets produced when an infected person coughs, sneezes, talks, or breathes. These droplets can land in the mouths or noses of people who are nearby or possibly be inhaled into the lungs.

Modes of Transmission:
- Close Contact: Direct contact with an infected person or their bodily fluids.
- Airborne Transmission: Virus particles can remain suspended in the air for some time, especially in poorly ventilated spaces.
- Surface Contact: Touching a contaminated surface and then touching the face.
Infection Process:
- The virus enters the body through the respiratory tract.
- The spike protein binds to the ACE2 receptor on host cells.
- The virus replicates inside the host cells.
- New virus particles are released, spreading the infection.
