Coronavirus symptoms, how to detect them at home, and how to protect yourself from the infection. The original post about the current coronavirus pandemic is published on BBC.

Coronavirus has spread to 169 countries or territories, including the UK, and claimed more than 18,000 lives.

So, what is the disease, how does it spread and when are people most infectious?

How do I Protect Myself from Coronavirus?

The best thing is regular and thorough hand washing, preferably with soap and water.

Coronavirus spreads when an infected person coughs 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 for limiting the spread.

Face masks do not provide effective protection, according to medical experts.

What are the Coronavirus Symptoms?

The symptoms of Coronavirus are as follows. Coronavirus infects the lungs. The symptoms start with a fever followed by a dry cough, which can lead to breathing problems.

This is a new, continuous cough and means coughing a lot for more than an hour, or having three or more coughing episodes in 24 hours (if you usually have a cough, it may be worse than usual).

It takes five days on average to start showing the Coronavirus symptoms, scientists have said, but some people will get symptoms much later than this. In fact, the World Health Organization (WHO) says the incubation period lasts up to 14 days.

Ear, nose, and throat specialists have also noticed rising reports of anosmia – the term for loss of smell.

And increasing numbers of people on social media have been reporting a lost sense of smell and taste. Some have tested positive for coronavirus.

However, the evidence so far is only anecdotal and viruses behind the common cold often lead to lost senses of smell and/or taste.

People will be most infectious when they have Coronavirus symptoms, but there have been suggestions some can spread the virus even before they are sick.

The early symptoms can easily be confused with other winter bugs including colds and flu.

How Deadly is Coronavirus?

The proportion dying from the disease appears low (between 1% and 2%) – but the figures are unreliable.

Thousands are being treated but may go on to die – so the death rate could be higher. But it may also be lower if lots of mild cases are unreported.

A World Health Organization examination of data from 56,000 patients suggests:

  • 6% become critically ill – lung failure, septic shock, organ failure and risk of death
  • 14% develop severe symptoms – difficulty breathing and shortness of breath
  • 80% develop mild symptoms – fever and cough and some may have pneumonia

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. The data from China also suggests that men are at a slightly higher risk of dying from the virus than women.

Treatment relies on keeping the patient’s body going, including breathing support, until their immune system can fight off the virus. Work to develop a vaccine is underway.
