Coronavirus: The number of fatalities increases to 81 and China is extending holidays.

Coronavirus update - roadblocks and ghost cities: in the province where the Coronavirus virus originated.

Coronavirus China.





The number of people killed by the new coronavirus in China has risen to 81, and almost 3,000 have been declared sick.

The National New Year was extended by three days to Sunday to limit the spread.

In Hubei, the total numbers of victims rose from 56 to 76, with another five cases reported in several other cities. Wuhan was sealed and travel bans were introduced in other cities.

More than 44 cases abroad were confirmed, affecting Thailand, the United States and Australia, according to a bbc news report on coronavirus

Apart from China, there were no deaths.

Coronavirus: Businesses are telling employees to stay home.
Chinese coronavirus: In Shanghai the authorities have prevented companies from returning to work until 10th February. The ban applies to all companies except public services, medical companies, medical service providers and supermarkets.

Meanwhile, World Health Organisation Director General Tedros Adhanom Ghebreyesus is in Beijing to discuss the epidemic with the Chinese government and health experts.

EPA: Cases of coronavirus in China.

81 Deaths.

2,827 Cases confirmed.

5,794 Suspected cases.

461 critical.

51 Recovered and released from the hospital.


After a wave of travel by the end of the year, the prospect of half a billion people returning to the country in trains, planes and buses is the last thing the government.

The Chinese Prime Minister Li Keqiang visited Wuhan, the capital of Hubei Province and the center of Hubei on Monday.

Experts suspect that there are many more people infected, but it is difficult to determine the actual number due to a number of factors, including the asymptomatic nature of some people.

Professor Neil Ferguson, a public health expert at Imperial College London, told the British newspaper The Guardian that his "best estimate" of the number of infected people is 100,000, while the data collected by the Department of Medicine at Li Ka Shing University in Hong Kong is probably 43,000.

Wuhan: The city where the virus started.

However, research by the University of Hong Kong has also shown that tens of thousands of people can be infected every day when the epidemic reaches its peak without public health intervention. As they predicted, the Dean of Medicine Gabriel Leung recommended "substantial and draconian measures" to limit the mobility of the population.

Since the coronavirus causes a severe acute respiratory infection, neither special medicine nor vaccine exists.

Most deaths occur among the elderly or those with previous respiratory problems.

What happens to Wuhan?

Mobility from the 11-million-strong city has been severely restricted, at the same time small vehicles have been prohibited from entering from the streets.

On the border with Hubei Province, workers check the temperature of people before entering the province.

Local government in Wuhan said no one has left the Chinese city in the last four days. About 4,096 tourists from Wuhan are still outside the national borders, whereas five million New Year's Eve tourists have abandoned the Chinese city before the shutdown.

The number of deaths is growing to at least 80 as thousands of new cases are registered in China.

2020 outbreak of the new coronavirus, which began in the Chinese city of Wuhan, has already claimed the lives of 80 people in China. There have been confirmed cases in many other countries. 

The vast majority of the almost 3,000 people infected by the virus to date are living inside China.

Wuhan City mayor said that in the capital of Hubei Province, about 3,000 patients were treated for the corona virus . Half of these patients, he said, will eventually get a positive test result for the disease.

Number of deaths across China had risen to at least 80 by Monday. Most of these deaths, 76, occurred in central Hubei province, the centre of the epidemic. The first death occurred on Saturday in Shanghai, a city of 24 million people.

There are 2,744 confirmed cases across China, of which 1,423 occurred in Hubei. According to the report, the youngest verified victim was a 9-month-old girl from Beijing. 


How the spread of the Wuhan virus affects the price of gold

The price of gold on Monday soared to its highest level in more than six years on fears of the spread of a new deadly coronavirus outside of China.

This reduced the investors ’appetite for investing in risky assets such as stocks, but sparked a demand for safe haven assets, including gold, MarketWatch said.

An outbreak of pneumonia in the Chinese city of Wuhan began in mid-December 2019, a previously unknown coronavirus became the causative agent. According to the latest data, about 2.8 thousand people were infected in China, 80 people were killed. 

In addition, cases have been reported in countries such as Thailand, Australia, Singapore, Japan, the United States, Malaysia and France.

“The spread of the Wuhan virus caused a sell-off in the stock markets, which is likely to push gold demand up,” said independent trader Stephen Innes.

Quotations of gold contracts for delivery in February reached 0.7% during trading on Monday - up to $ 1,582.2 an ounce. This is the highest level since 2013, according to FactSet. Silver for March delivery rose 0.5% to $ 18.2 an ounce.

What are Coronaviruses

Coronaviruses are a large group (i.e. classified taxonomic ) of RNA viruses with a common virus shell, belonging to the Taxonomic Ortho Coronaviridae subfamily of the Coronaviridae family. 

Depending on each type, coronavirus can cause a variety of diseases, from colds to more serious ones such as bronchitis, bronchitis, pneumonia, Middle East respiratory syndrome (MERS-CoV), 6 severe acute respiratory syndrome (SARS-CoV), 6, etc., which are all common in the Coronaviridae family.

Most people become infected with these viruses at some time in their life.

To date, 39 coronavirus species have been recorded. Several species are of recent investigation because several particular strains had not been previously identified in humans.

There is little information on the transmission, severity and clinical impact and there are no approved treatments to date, however several of the symptoms can be treated, the therapeutic options depend on the clinical status of each patient. 

With the development of a diagnostic test PCR (polymerase chain reaction) researchers can detected the specific infection coronavirus Wuhan (2019-nCoV), which is causing an epidemic of pneumonia in 2019 and 2020.

History and evolution of the virus.

Recent common ancestor of the coronavirus has been found in the 9` century BC. Studies conducted during the last decade of the twentieth century managed to date the most recent common ancestors of:

  • Betacoronavirus: 3300 a. C.
  • Deltacoronavirus: 3000 a. C.
  • Gammacoronavirus: 2800 a. C.
  • Alphacoronavirus: 2400 a. C.


According to these studies, at that time the main factor in the source of the coronavirus was warm blood, particularly from bats and birds.

Bovine coronavirus separated from horse coronavirus in the late 18th century. The cattle coronavirus and the OC43 human coronavirus separated in 1899. Another estimate is that the OC43 human coronavirus separated from the bovine coronavirus in 1890. 

The Bovine Coronavirus and Canine respiratory coronavirus (CRCoV) separated from their common ancestor in 1951. The most common ancestor to the OC43 human coronavirus dates from the 1950s. 

The coronavirus respiratory syndrome of Middle Eastern, although associated with several types of bats, seems to have deviated from it several centuries ago. The coronavirus of bats is more closely associated with the coronavirus of SARS, from which it separated in 1986.
