Cold or COVID – Quick Answer

Cold: A mild viral infection primarily affecting the nose and throat. Symptoms often include:

Runny or stuffy nose
Sneezing
Sore throat
Mild fatigue
Occasional mild fever

COVID-19: A viral respiratory infection caused by SARS-CoV-2. Symptoms can overlap but may be more severe:

Fever or chills
Persistent cough
Loss of taste or smell
Shortness of breath
Severe fatigue or body aches
Headaches

Quick tip: If you have loss of taste or smell, high fever, or breathing difficulties, treat it as COVID until tested negative.

Example:

A person with mild sneezing and a runny nose likely has a cold.
A person with fever, cough, and sudden loss of smell should consider COVID testing immediately.

The Origin of Cold or COVID

The term cold has been used since the Middle Ages to describe mild respiratory infections caused by various viruses. The word itself comes from Old English ceald, meaning low temperature, as people associated chills with sickness.

COVID is short for Coronavirus Disease 2019, first identified in Wuhan, China, in late 2019. It refers to the viral infection caused by SARS-CoV-2, a new strain of coronavirus. Unlike the common cold, which can be caused by hundreds of viruses (like rhinoviruses), COVID is caused by a single, highly contagious virus with global implications.

Historical note: While colds have existed for centuries, COVID-19 rapidly became a pandemic, leading to new terminology in everyday language and official health communication.

Key rule: Use all-caps COVID when referring to the disease (both US and UK). The hyphen and year (COVID-19) are also standard internationally.

Which Spelling Should You Use?

United States: Use COVID-19 in all professional, educational, and medical writing.
United Kingdom & Commonwealth: COVID-19 is standard, but sometimes news articles lowercase it as Covid-19.

Advice: Avoid writing covid, covid19, or Cold or covid inconsistently in content. Official spelling is recognized worldwide.
