the number of cases worldwide coronavirus has overtaken that the SARS epidemic, which spread to more than two dozen countries in 2003.
There are approximately 8,100 cases of Sars – acute respiratory syndrome -. reported during an outbreak of eight months
But the nearly 10,000 cases of the new virus have been confirmed, mostly in China, since it emerged in December.
More than 100 cases have been reported outside of China, in 22 countries.
The death toll so far stands at 213 – all in China. In total, 774 people were killed by Sars.
On Thursday, during a new outbreak.
Britain on Friday
In another development, the US also declared a public health emergency and said it would prohibit any foreign nationals who have visited China in the last two weeks of entering the country.
Estimated by the University of Hong Kong shows the actual number of cases may be much higher than official figures suggest. Based on the mathematical model of the outbreak, the experts there say more than 75,000 people may have been infected in the Chinese city of Wuhan alone, where the virus originated.
Most of the cases outside China on those who have been to Wuhan. But Germany, Japan, Vietnam, USA, Thailand and South Korea have reported cases of person-to-person -. Patients infected by people who have traveled to China head
Wuhan Communist Party said on Friday the city should take quick steps to contain the virus.
“If the measures of strict control has been taken, the result will be better than now,” Ma Guoqiang told state broadcaster CCTV.
As governments around the world acted to contain the virus, WHO spokesman Chris Lindmeier warned that the closure of the border could actually accelerate the spread, with tourist countries illegal entry.
“As we know from other scenarios, either Ebola or other cases, whenever people want to travel, they will. And if the official line is not opened, they will find an unofficial way,” he said.
He said that the best way to track the virus in official border crossings.
Sars is a type of coronavirus that first appeared in China’s Guangdong province in November 2002, when the outbreak ends the following July, it spread to more than two dozen countries.
The new coronavirus appeared only last month. So far, it has spread to countries with fewer and – while many people have been infected globally – has resulted in fewer deaths.
On Wednesday, the number of confirmed cases in China surpassed the SARS epidemic.
Sars is also estimated to have cost the global economy more than $ 30bn (£ 22bn).
But economists said the new coronavirus may have greater impact on the world economy. This has forced global companies including technology giants, carmakers and retailers to close while in China.
China has also been criticized by the UN global health bodies to hide the scale of the original Sars outbreak.
This has been hailed as the latest virus responded with harsh measures, including effective quarantining of millions of people in cities.
But in an interview with CCTV on Friday, the head of the Communist Party of Wuhan said transport restrictions should be brought in at least 10 days in advance.
“The epidemic might have lightened a little, and not up to the current situation,” Ma said.
The forecast of the University of Hong Kong showed the epidemic is doubling in size roughly every week, and that the cities of China may have imported some cases sufficient to start a local epidemic.
“big cities overseas transport links close to China has the potential to also become the epicenter of the outbreak since it spreads large pre-symptom cases except public health interventions are quite large in both population and individual level be implemented immediately,” said Professor Joseph Wu.
Why is this outbreak is more difficult to stop than Sars?
The answer is not down to China – the speed and scale of the state’s response to the new virus is widely considered unprecedented. The difference is how the virus behaves in the human body.
Sars is brutalInfections that you can not miss – the patient is infectious only when they have symptoms. This makes it relatively easy to isolate sick and quarantine anyone who may have been exposed.
But the new virus-nCov 2019, is more difficult to spot and therefore more difficult to stop.
from the perspective of the virus, have survived much smarter strategy evolution of Sars.
The best estimate is only one-in-five cases cause severe symptoms, so it is not an infected person turned in a hospital, you have to go out and find them.
and we get a detailed documented cases of people spreading the virus even before they have symptoms.
There is a tendency to only focus on how deadly the virus is. But this, in combination with the virus’s ability to spread, which determines the actual threat.
A confirmed case in Tibet means the virus has now reached every county in mainland China.
The central province of Hubei, where most deaths occur, is in a state of lockdown. Province of 60 million people is home to Wuhan, which is the heart of the outbreak.
The city had effectively been closed and China has put a lot of restrictions on the transportation in place to prevent the spread of the virus. People who have been in Hubei were also told to work from home.
China said it would send a charter plane to bring back the Hubei population residing abroad “as soon as possible”. A foreign ministry spokesman said this was due to “practical difficulties” Chinese citizens have faced abroad.
This virus affects the Chinese economy, the world’s second largest, with more and more countries advised their citizens to avoid all non-essential travel to the country.
voluntary evacuation of hundreds of foreign nationals from Wuhan progress.
Britain, Australia, South Korea, Singapore and New Zealand are expected to quarantine all the refugees for two weeks to monitor them for symptoms and avoid contagion.
