Covid symptoms: What are they and how do I protect myself?

There are three main symptoms of coronavirus.

If you have any of them, you should get a test.

Public Health England says about 85% of people with Covid will have at least one of these symptoms.

People infected with new variants such as Delta may be more likely to have other symptoms, such as headache, sore throat or a runny nose, according to research from the Zoe Covid Study and an ONS survey.

If you have any symptoms you should get tested as soon as possible and not leave home for any other reason.

It takes five days on average from the moment you're infected for symptoms to show.

No - it can affect multiple organs and has several less common symptoms.

Scientists using data on the health of four million people say Covid has six sub-types:

Researchers think that vomiting, diarrhoea and abdominal cramps could be a sign of coronavirus in children.

Some people who catch Covid develop chilblain-like lesions on their toes or fingers.

It can happen to anyone, but is more common in children and teenagers.

For some it's painless, but the rash can be very sore and itchy.

It appears to be a side effect of the body switching into attack mode to fight off the virus.

Writing in the British Journal of Dermatology, researchers say they've pinpointed which parts of the immune system are responsible, which should lead to better treatments.

Lots of other viruses have similar symptoms to Covid, including flu.

Public Health England says just under half of people who have one of the three main Covid symptoms will not have it.

If you have a positive test result you should self-isolate at home for at least 10 days from the time symptoms started.

Most people will only have mild symptoms, which can be managed with pain relief (like paracetamol), bed rest and fluids.

You should not go to a GP surgery, pharmacy or hospital.

Since 16 August, people who are double jabbed (or aged under 18) don't have to self-isolate if they're identified as a close contact of a person who tests positive.

Getting vaccinated is the best way to prevent serious illness, hospitalisation or death from Covid.

If you are seriously unwell and you have a medical emergency you should call 999 - this includes feeling so breathless that you can't speak more than a few words.

If you're worried your symptoms are getting worse, use the NHS 111 website England, NHS Inform in Scotland or the equivalents in Wales and Northern Ireland.

The main reason people need hospital care is for difficulty breathing where they may be given oxygen.

The most seriously ill patients may require ventilation - where patients are sedated and air is pushed into their lungs.

Older people, and those with pre-existing medical conditions (such as asthma, diabetes, heart disease, high blood pressure), are more likely to become severely ill. Men are at slightly higher risk of dying from the virus than women.
