Coronavirus Diagnosis Treatment Symptoms Variants

Coronavirus Diagnosis Treatment Symptoms Variants main thing is that There is no treatment for coronavirus, but medical care can treat most of the symptoms. Antibiotics do not work on viruses.

A virus causing severe lung disease that started in China has spread to more than 50 countries, including the UK. Coronavirus is threatening due to its lethality — and its cost. A Miami Herald report from Monday has widely circulated around social media, documenting Miami resident Osmel Martinez Azcue checking himself into Miami’s Jackson Memorial Hospital for flu-like symptoms after arriving back in the US from a work trip to China. Azcue was concerned that his symptoms could have come from exposure to the novel coronavirus rapidly spreading in China and elsewhere.

The coronavirus had infected 78,927 people in China as of 28 February, with 2,790 of them dying.

What are the symptoms?

It seems to start with a fever, followed by a dry cough.

After a week, it leads to shortness of breath and some patients require hospital treatment.

The incubation period – between infection and showing any symptoms – lasts up to 14 days, according to the World Health Organization (WHO).

But some researchers say it may be as long as 24 days.

And Chinese scientists say some people may be infectious even before their symptoms appear.Coronavirus Diagnosis Treatment Symptoms Variants

How deadly is the coronavirus?

Based on data from 44,000 patients with this coronavirus, the WHO says:

  • 81% develop mild symptoms
  • 14% develop severe symptoms
  • 5% become critically ill

The proportion dying from the disease, which has been named Covid-19, appears low (between 1% and 2%) – but the figures are unreliable.

Thousands are still being treated but may go on to die – so the death rate could be higher. But it is also unclear how many mild cases remain unreported – so the death rate could also be lower.

To put this into context, about one billion people catch influenza every year, with between 290,000 and 650,000 deaths. The severity of flu changes every year.

Can coronavirus be treated or cured?

Right now, treatment relies on the basics – keeping the patient’s body going, including breathing support, until their immune system can fight off the virus.

However, the work to develop a vaccine is under way and it is hoped there will be human trials before the end of the year.

Hospitals are also testing anti-viral drugs to see if they have an impact.

How can I protect myself?

What should I do to prevent catching and spreading the virus? NHS advice: wash hands frequently with soap and water or sanitiser gel; catch coughs and sneezes with disposable tissues; throw away used tissues (then wash hands); if you don't have a tissue, use your sleeve; avoid touching your eyes, nose and mouth with unwashed hands; avoid close contact with people who are unwell

What is the advice in the UK?

Anyone experiencing symptoms, even if mild, after travelling from mainland China, Thailand, Japan, Republic of Korea, Hong Kong, Taiwan, Singapore, Malaysia or Macau in the last 14 days, is advised to stay indoors and call the NHS 111 phone service.

If you have returned from the following specific areas since February 19, you should call NHS 111 and stay indoors and avoid contact with other people even if you do not have symptoms:

  • Iran
  • lockdown areas in northern Italy
  • special care zones in South Korea
  • Hubei province

If you have returned from the following areas since February 19 and develop symptoms – even mild ones – stay indoors, avoid contact with others and call NHS 111:

  • Northern Italy (above but not including Pisa, Florence and Rimini)
  • Vietnam
  • Cambodia
  • Laos
  • Myanmar

The Foreign Office now advises against all but essential travel to 10 small towns in Lombardy and one in Veneto in Italy, which have been isolated by the country’s authorities

How fast is it spreading?

Thousands of new cases are being reported each day. However, analysts believe the true scale could be 10 times larger than official figures.

Outbreaks have now occurred in South Korea, Italy and Iran, raising fears that it could become a pandemic. A pandemic is declared when an infectious disease threatens different parts of the world simultaneously.

The WHO has said it is concerned about the number of cases with no clear link to China or other confirmed cases. It has said the window of opportunity to contain the virus was “narrowing”.

With colds and flu tending to spread fastest in the winter, there is hope the turning of the seasons may help stem the outbreak.

However, a different strain of coronavirus – Middle East respiratory syndrome – emerged in the summer, in Saudi Arabia, so there’s no guarantee warmer weather will halt the outbreak.

How did it start?

This virus is not really “new” – it is just new to humans, having jumped from one species to another.

Many of the early cases were linked to the South China Seafood Wholesale Market, in Wuhan.

In China, a lot of people come into close contact with animals harbouring viruses – and the country’s dense urban population means the disease can be easily spread.

Severe acute respiratory syndrome (Sars), which is also caused by a coronavirus, started off in bats and then infected the civet cat, which in turn passed it on to humans.

The Sars outbreak, which started in China in 2002, killed 774 of the 8,098 people infected.

The current virus – one of seven types of coronavirus – does not seem to be mutating so far. But while it appears stable, this is something scientists will be watching closely.
