A medical test that can show if a person has had the coronavirus and now has some immunity. The test detects antibodies in the blood, which are produced by the body to fight off the disease.
Someone who has a disease but does not have any of the symptoms it causes. Some studies suggest some people with coronavirus carry the disease but don’t show the common symptoms, such as a persistent cough or high temperature.
The first part of the UK’s strategy to deal with the coronavirus, which involved trying to identify infected people early and trace anyone who had been in close contact with them.
One of a group of viruses that can cause severe or mild illness in humans and animals. The coronavirus currently sweeping the world causes the disease Covid-19. The common cold and influenza (flu) are other types of coronaviruses.
The disease caused by the coronavirus first detected in Wuhan, China, in late 2019. It primarily affects the lungs.
The second part of the UK’s strategy to deal with the coronavirus, in which measures such as social distancing are used to delay its spread.
Fixed penalty notice
A fine designed to deal with an offence on the spot, instead of in court. These are often for driving offences, but now also cover anti-social behaviour and breaches of the coronavirus lockdown.
Flatten the curve
Health experts use a line on a chart to show numbers of new coronavirus cases. If a lot of people get the virus in a short period of time, the line might rise sharply and look a bit like a mountain. However, taking measures to reduce infections can spread cases out over a longer period and means the “curve” is flatter. This makes it easier for health systems to cope.
Short for influenza, a virus that routinely causes disease in humans and animals, in seasonal epidemics.
Supports firms hit by coronavirus by temporarily helping pay the wages of some staff. It allows employees to remain on the payroll, even though they aren’t working.
How the spread of a disease slows after a sufficiently large proportion of a population has been exposed to it.
A person whose body can withstand or fend off a disease is said to be immune to it. Once a person has recovered from the disease caused by the coronavirus, Covid-19, for example, it is thought they cannot catch it again for a certain period of time.
