What is coronavirus?

Coronavirus causes a new illness (COVID-19) that mainly affects your lungs and airways.
Symptoms in most people will be mild – a high temperature or new continuous cough, or loss of sense of smell or taste. Some people will also have difficulty with breathing (shortness of breath). A few people with COVID-19 will get severe symptoms and need medical attention. Older people and those with a long-term health condition (for example, lung disease, heart failure, diabetes) or a weakened immune system (for example, because of HIV or chemotherapy) are more likely to get worse symptoms. These are people who are offered the regular flu jab every year in the autumn.
The higher-risk groups for severe coronavirus illness include almost everyone with dementia, and many older family carers.
