The COVID-19 pandemic has not only reshaped our daily lives but also introduced a new lexicon that has become an integral part of our global conversation. As we navigate through this unprecedented time, understanding the key terms and phrases related to the virus is crucial for staying informed and communicating effectively. This article aims to provide a comprehensive guide to the English expressions that have emerged in response to the pandemic.

1、Coronavirus (COVID-19): The term "coronavirus" refers to a large family of viruses that can cause illnesses ranging from the common cold to more severe diseases. The specific virus that caused the pandemic is known as SARS-CoV-2, and the disease it causes is called COVID-19, which stands for "coronavirus disease 2019."

2、Pandemic: A pandemic is an outbreak of a disease that occurs over a wide geographic area and affects an exceptionally high proportion of the population. The World Health Organization (WHO) declared COVID-19 a pandemic on March 11, 2020.

3、Outbreak: An outbreak refers to a sudden increase in the number of cases of a disease in a particular area or among a specific group of people.

4、Social Distancing/Physical Distancing: This term refers to the practice of maintaining a safe distance from others (usually 6 feet or 2 meters) to prevent the spread of the virus. It has become a cornerstone of public health advice during the pandemic.

5、Quarantine: Quarantine is the separation of a person or group of people reasonably believed to have been exposed to a communicable disease but not yet symptomatic, from others who have not been so exposed, to prevent the possible spread of the communicable disease.

6、Isolation: Isolation is the separation of a person or group known to have a contagious disease from those who are not infected, to prevent the spread of the disease.

7、Lockdown: A lockdown is a strict restriction on movement or access to a community or facility, implemented to control the spread of a contagious disease.

8、Vaccine: A vaccine is a biological preparation that provides active acquired immunity to a particular disease. The development and distribution of COVID-19 vaccines have been a global priority.

9、Booster Shot: A booster shot is an additional dose of a vaccine given to maintain immunity levels. For COVID-19, booster shots have been recommended to extend the duration of protection against the virus.

10、Vaccination Passport: A vaccination passport is a digital or physical document that certifies an individual's COVID-19 vaccination status, often required for international travel or entry into certain venues.

15、N95 Mask: An N95 mask is a type of respiratory protective device designed to filter out at least 95% of airborne particles, including large respiratory droplets containing the virus.

16、Virus Variants: Virus variants are changes in the virus's genetic material. Variants of concern have been identified due to their potential to increase transmissibility, severity of disease, or decrease in effectiveness of public health measures.

17、Herd Immunity: Herd immunity is a form of indirect protection from infectious disease that occurs when a large percentage of a population becomes immune to the disease, either through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who are not immune.

18、Telemedicine: Telemedicine is the remote diagnosis and treatment of patients via telecommunications technology, which has seen a surge during the pandemic to minimize in-person contact.

19、Zoom Fatigue: This term describes the physical and mental exhaustion that can result from prolonged exposure to videoconferencing, a common mode of communication during lockdowns and social distancing measures.

Understanding these terms is essential for anyone looking to engage in informed discussions about the pandemic, whether in a professional setting, with friends and family, or on social media.
