What are the symptoms caused by the virus from Wuhan in China, how does it spread, and should you call a doctor?
What is Covid-19 – the illness that started in Wuhan?
It is caused by a member of the coronavirus family that has never been encountered before. Like other coronaviruses, it’s come from animals. Many of these initially infected either worked or frequently shopped within the Huanan seafood wholesale market within the center of the Chinese city.
What are the symptoms this coronavirus causes?
The virus can cause pneumonia. those that have fallen ill are reported to suffer coughs, fever and breathing difficulties. In severe cases, there is often organ failure. As this is often viral infection, antibiotics are of no use.
The antiviral drugs we’ve against the flu won’t work. Recovery depends on the strength of the system. Many of these who have died were already in poor health.
Should I’m going to the doctor if I even have a cough?
In the UK, the medical advice is that if you’ve got recently traveled from areas suffering from a coronavirus, you should:
• stay indoors and avoid contact with people as you’d with the flu.
• call NHS 111 to tell them of your recent visit to the world.
Is the virus being transmitted from one person to another?
China’s national health commission has confirmed human-to-human transmission, and there are such transmissions elsewhere.
How many people are affected?
As of 4 March, the worldwide price is 3,190, while quite 93,000 people are infected in additional than 80 countries. In China, there are 2,981 deaths, and there are 80,270 cases altogether.
South Korea, the state worst hit by the outbreak outside China, has had 5,328 cases. quite 44,000 people in China have recovered from Covid-19.
There are 51 recorded cases and no fatalities so far within the UK. There are 41 cases of the virus in Australia.
Why is that this worse than normal influenza and the way worried are the experts?
We don’t yet skill dangerous the new coronavirus is, and that we won’t know until more data comes in. The death rate is around 2% within the epicenter of the outbreak, Hubei province, and fewer than that elsewhere. For comparison, seasonal flu typically features a death rate below 1% and is assumed to cause about 400,000 deaths annually globally. SARS had a death rate of quite 10%.
Another key unknown is how contagious the coronavirus is. an important difference is that unlike flu, there’s no vaccine for the new coronavirus, which suggests it’s harder for vulnerable members of the population – elderly people or those with existing respiratory or immune problems – to guard themselves. Handwashing and avoiding people if you are feeling unwell are important. One sensible step is to urge the flu vaccine, which can reduce the burden on health services if the outbreak turns into a wider epidemic.
Have there been other coronaviruses?
Severe acute respiratory syndrome (Sars) and Middle Eastern respiratory syndrome (Mers) are both caused by coronaviruses that came from animals. In 2002, Sars spread virtually unchecked to 37 countries, causing global panic, infecting quite 8,000 people and killing quite 750. Mers appears to be less easily passed from human to human, but has greater lethality, killing 35% of about 2,500 people that are infected.
Is the outbreak an epidemic and will we panic?
No. an epidemic, in WHO terms, is “the worldwide spread of a disease”. The spread of the virus outside China is worrying but not an unexpected development. The WHO has declared the outbreak to be a public health emergency of international concern. The key issues are how transmissible this new coronavirus is between people, and what proportion becomes severely ill and find yourself within the hospital. Often viruses that spread easily tend to possess a milder impact. Generally, the coronavirus appears to be hitting older people hardest, with few cases in children.
