COVID-19 is a disease whose name derives from “coronavirus disease 2019.” It is caused by an infection from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). COVID-19 is often referred to more simply as COVID.
COVID-19 primarily affects the respiratory system. It has a 0.66% fatality rate, with those at an increased age, with a high body mass index, or with a history of lung or heart diseases being at a higher risk. In 80% of cases, it produces only mild symptoms.
However, in severe cases, it can cause critical illness, potentially leading to respiratory failure, septic shock, and multiple organ dysfunction syndrome.
A longer-term, but less understood, condition is called “long COVID,” which can result in post-infection conditions, including fatigue, heart problems, neurological concerns, and digestive issues.
The virus that causes COVID-19 is highly infectious, which led to a pandemic that was officially declared by the World Health Organization (WHO) on March 11, 2020. While the end of the pandemic was not officially announced by the WHO, many leading experts pinpointed its conclusion as occurring in the late spring or early summer of 2022.
COVID-19 had a profound impact on clinical laboratories, with a huge demand for SARS-CoV-2 testing occurring throughout the world, stimulated by government subsidies.
The COVID-19 pandemic resulted in lockdowns, masking, social distancing, and several other infection prevention measures to attempt to slow the spread of SARS-CoV-2. It also disrupted social, business, and educational activities throughout the world.
Several vaccines were developed in late 2020 and early 2021 to prevent the spread of COVID-19. While initially effective, such vaccination shows waning effectiveness over time, requiring booster shots. The vaccines were developed quickly—in less than a year—and are notable for being the first time that mRNA vaccine technology was ever authorized and approved for general use by healthcare regulators.
While the term “COVID-19” technically refers to the disease caused by SARS-CoV-2, the term is often misused to describe the virus. “COVID-19 testing”, for example, was often used to describe what would correctly have been referred to as SARS-CoV-2 testing, as the presence of the SARS-CoV-2 infection does not always cause COVID-19. “Asymptomatic COVID-19” is another misuse of the term, as COVID-19 is a disease that will produce some form of symptoms.
The nuances of the difference between SARS-CoV-2 and COVID-19 have generally been lost on the public, the media, and government officials, resulting in the two terms being used interchangeably.
