What do all the terms mean?

Skip to main story

• Asymptomatic

  A person who has a disease but is displaying no symptoms of that illness. A study of one village in Italy suggests 50-75% of Covid-19 cases there could be asymptomatic.

• Containment phase

  The first part of the UK’s strategy to deal with coronavirus involved trying to catch cases early and trace anyone who had been in close contact

• Coronavirus

  A generic name for a group of viruses which cause illness and disease in humans and animals. The disease caused can be severe or mild. The common cold and influenza (flu) are examples of coronaviruses.

• Covid-19

  Covid-19 is the name of the specific disease caused by the type of coronavirus first detected in Wuhan in China in late 2019. It primarily affects the lungs.

• Delay phase

  The second part of the UK strategy to deal with coronavirus involves delaying its spread by introducing ‘social distancing’ where people avoid close contact with others by working from home, avoiding public transport and restricting major events.

• Flatten the curve

  Describes measures to prevent a very high number of cases of disease occurring at the same time and potentially overloading health services. By slowing transmission rates through measures like social distancing, cases take place over a longer period of time and hospitals remain within capacity – the ‘peak’ of cases is flattened into a smoother curve on a chart.

• Flu

  Flu is a virus which routinely causes disease in humans and animals. There are two main types or strains of flu, A and B. These are responsible for seasonal flu epidemics.

• Herd immunity

  Describes how the spread of a disease can be limited by a certain number of people (or animals) being exposed to it and acquiring immunity, therefore slowing its spread.

• Immune

  A person whose body can withstand or fend off disease is said to be immune to that disease. Once a person has recovered from Covid-19, they are thought to have some immunity to the disease – that is, they cannot get it again – for a certain period of time. However how long immunity lasts is not known, and there have been some reports of people testing positive for a second time.

• Incubation period

  The period of time between catching a disease and the body starting to display symptoms.

• Lockdown

  Any restriction on movement or daily life, where public buildings are closed and people urged to remain at home behind closed doors. Lockdowns have been imposed in several countries as part of drastic efforts to control the spread of disease.

• Mitigation phase

  The fourth part of the UK’s strategy to deal with coronavirus involves mitigating the impact of a high number of case on public services. This could mean the NHS stopping all non-critical care and police only responding to major crimes and emergencies.

• NHS 111

  The NHS’s 24-hour phone line which offers medical advice to anyone who rings it. Anyone who suspects they may have coronavirus symptoms is asked to call NHS 111 rather than attend a GP surgery or hospital A&E.

• Outbreak

  Multiple cases of a disease occuring rapidly, either in a cluster or in multiple locations, is known as an outbreak.

• Pandemic

  An epidemic of serious disease spreading rapidly in several countries simultaneously is known as a pandemic.

• Quarantine

  Means the isolation of people who have been exposed to a contagious disease to prevent it spreading to others.

• Sars

  Sars or SARS refers to Severe Acute Respiratory Syndrome, a type of coronavirus which emerged in Asia in 2003.

• Self-isolation

  Means staying inside and avoiding all contact with other people with the aim of preventing any possible spread of disease.

• Social distancing

  Taking measures to avoid coming into direct contact with others. This can mean avoiding any social gatherings, and in daily life, keeping a distance of at least 2 metres from other people.

• State of emergency

  Usually refers to measures taken by a government to restrict daily life while it deals with a crisis. This can involve closing schools and workplaces, restricting the movement of people and even possibly deploying the armed forces to support regular emergency services.

• Symptoms

  Symptoms are any outward physical sign of disease, such as a cough, sore throat or fever. They are triggered by the body’s immune system as it attempts to fight off the infection.

• Vaccine

  A substance which causes the body to produce antibodies, which fight off a disease, and gives immunity against further infection.

• Virus

  A tiny agent which replicates inside the living cells of any organism. Viruses can cause these cells to die and interupt the body’s normal chemical processes, causing disease.
