Coronavirus jargon doing your head in? We're here to help. Here are quick definitions of some terminologies that you may be wondering about.Coronavirus: A family of viruses that cause illnesses ranging from the common cold to more severe diseases such as SARS and MERS.SARS-CoV-2: The name given to the coronavirus that causes COVID-19 which was first discovered late last year in the city of Wuhan in China.COVID-19: An acronym created by the World Health Organization (WHO) that stands for the respiratory disease caused by (SARS-CoV-2). It stands for "coronavirus disease of 2019".Endemic: A disease that is recurring among a particular group of people or in a particular region, such as malaria.Epidemic: The widespread occurrence of an infectious disease in a population at a particular time. COVID-19 is a pandemic (because of its global spread), but it is also an epidemic in Italy.Pandemic: An epidemic that has spread over several countries or continents and is affecting a large number of people.Flattening the curve: Slowing a virus's spread to lower the peak number of cases and related demands on hospitals and infrastructure.Incubation: The incubation period is the time it takes for symptoms to appear after a person is infected. According to the WHO, most estimates of the incubation period for COVID-19 range from 1-14 days, most commonly around five days.PCR test: This is a genetic test used to find out if you have a COVID-19 infection. A swab is taken from the mucous membrane lining your nose and throat. The sample genetic instructions contained within the virus are turned into DNA then amplified in a process called polymerase chain reaction - hence PCR. This test can take hours to get a result, but several companies are trying to develop rapid molecular testing methods.R0 (pronounced R nought): The average number of people a sick person will infect. The R0 changes depending on the cases identified and how many people are tested. The R0 of Covid-19 is between two and three, meaning that each infected person will infect 2-3 other people. This is why it can spread so quickly.PPE: Personal Protective Equipment, it includes, but is not limited to, medically approved gowns, aprons or coveralls, gloves, respirators, face shields and masks.Self-quarantine: Staying home and away from other people as much as possible after exposure or potential exposure to an infection.Quarantine: Separating and restricting the movement of people exposed or suspected to be exposed to a contagious disease.Self-isolation: Isolation, as opposed to quarantine, is what someone who is confirmed to be ill with a communicable disease has to do to separate themselves from healthy people around them.Social distancing: increasing the physical space between people to slow the spread of the virus. This list includes staying home unless it is vital that you go outside, catching up with loved ones online instead of in person, strictly limiting the number of visitors to your home, and staying away from other people when you are in a public space. The WHO recommends being more than one metre away from the nearest person, while some health experts have suggested maintaining a distance of at least two metres from others.Immuno-compromised: People who have a weak immunity system due to a chronic health condition, medication or malnutrition.Underlying condition: A long-term health issue such as asthma, diabetes, HIV, chronic lung disease, cancer and more.Now you are in the know- we hope you impress your friends at your next online cocktail party!Pics: courtesy
