The NHS has listed three main symptoms of coronavirus, that people should be aware of and ready to act upon.
What are the symptoms?
- A new, continuous cough, where you cough a lot for more than an hour, or have three or more coughing episodes in 24 hours
- Fever – where your temperature is above 37.8C
- Loss of smell or taste
If you, or someone you live with, has any of these symptoms the advice is stay at home to stop the risk of giving coronavirus to others.
The US Centers for Disease Control and Prevention’s list of symptoms also includes chills, repeated shaking, muscle pain and sore throat.
It takes five days on average to start showing the symptoms, but some people will get them much later. The World Health Organization says incubation lasts up to 14 days.
When do people need to go to hospital?
The majority of people with coronavirus will recover after rest and pain relief (such as paracetamol).
The main reason people need hospital treatment is difficulty breathing.
Doctors may scan the lungs to see how badly they are affected and give support, such as oxygen or ventilation, if needed.
If you are so breathless that you are unable to speak more than a few words you will be told to call 999, as this is a medical emergency.
If you become so ill that you’ve stopped doing all of your usual daily activities then it will advise speaking to a nurse.
What happens in intensive care?
Intensive care units are specialist wards for people who are very ill.
Coronavirus patients will get oxygen support, which can involve using a facemask or a tube in the nose.
The most invasive way – for the most seriously ill patients – is ventilation where air, with increased levels of oxygen, is pushed into the lungs via a tube in the mouth, nose or through a small cut in the throat.
What should I do if I have mild symptoms?
Patients with mild symptoms should self-isolate at home for at least seven days.
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.
How do I protect myself?
The best thing is regular and thorough hand washing, preferably with soap and water.
Coronavirus spreads when an infected person coughs or sneezes small droplets – packed with the virus – into the air. These can be breathed in, or cause an infection if you touch a surface they have landed on, then your eyes, nose or mouth.
So, coughing and sneezing into tissues, not touching your face with unwashed hands, and avoiding close contact with infected people are important.
People will be most infectious when they have symptoms, but some may spread the virus even before they are sick.
