The World Health Organisation (WHO) has on Friday morning declared a coronavirus international emergency over fears of its global spread as China vowed to contain the ‘devil’ virus.

More than 9320 people have been infected worldwide, surpassing the SARS outbreak in 2002-03, and 170 people have died with cases now reported in all mainland Chinese provinces.

There are nine confirmed cases in Australia and 212 confirmed deaths so far in China.

Fresh fears that the deadly illness is sweeping the world came as densely populated India and the Philippines confirmed their first cases and Russia closed its border with China.

The virus has now landed in 18 countries, with cases in Australia climbing to nine after Victoria confirmed its third victim and Queensland declared its second case.

Johns Hopkins University’s Centre for Systems Science and Engineering in the US has produced a dashboard (updated at regular interviews with WHO data) indicating where confirmed cases are and the spread of the virus in other countries.

The dashboard is updated regularly with data from @WHO, @CDCgov, and others to illustrate how the virus is spreading in China and beyond. #nCoV2019https://hub.jhu.edu/2020/01/23/coronavirus-outbreak-mapping-tool-649-em1-art1-dtd-health/ …

WHO director general Tedros Adhanom Ghebreyesus praised China’s handling of the outbreak but said the global spread had prompted the declaration of “a public health emergency of international concern”.

“We don’t know what sort of damage this virus could do if it were to spread in a country with a weaker health system,” he warned.

“We must act now to help countries prepare for that possibility.”

“The main reason for this declaration is not because of what is happening in China, but because of what is happening in other countries.”

Dr Tedros said the declaration was “not a vote of no confidence in China”.

“On the contrary, WHO continues to have confidence in China’s capacity to control the outbreak,” he said.

“The speed with which China detected the outbreak, isolated the virus, sequenced the genome and shared it with WHO and the world are very impressive.”

The WHO declaration will trigger tighter containment and information-sharing guidelines but at this stage will not include restrictions to international travel and trade.

“There is no reason for measures that unnecessarily interfere with international travel and trade.

“We call on all countries to implement decisions that are evidence-based and consistent.”
Although there are more than 9000 people infected around the world, the death rate has been much lower than SARS which killed 774 people worldwide from about 5300 cases.

Coronavirus has claimed 212 lives, all of them in China where the outbreak originated in an illegal wildlife market, spurring anti-China sentiment and a wave of mask-buying.

Dr Tedros said there were 98 cases of coronavirus outside China, including eight cases of human-to-human transmission in four countries – Germany, Japan, Vietnam and the USA.

The WHO emergency declaration may disappoint Beijing, which had expressed confidence in defeating the “devil” virus, as dubbed by China’s president Xi Jinping.
Passenger panic

Meanwhile, the Queensland government invoked a public health emergency order on Thursday authorising the right to detain suspected carriers after two Chinese nationals flew to the Gold Coast, potentially infecting passengers on the flight.

Authorities are urgently contacting about 170 passengers on Tiger Air flight TT566 from Melbourne to the Gold Coast on Monday over fears they may have contracted the deadly coronavirus.

Two Chinese nationals on the flight – a 42-year-old female and 44-year-old male – were part of a tour group that had come from the Chinese city of Wuhan, the epicentre of the outbreak where 11 million people are in lockdown.

Victoria’s third case, a woman aged in her 40s, is in a stable condition in isolation at the Royal Melbourne Hospital.

As virus panic grips humanity, a number of countries including Australia are racing to evacuate their citizens from Wuhan and airlines such as British Airways have cancelled some flights to China.

Qantas has been accused of putting profits first by continuing to fly to infected China.

A race against time is also underway to develop a vaccine, with Australia’s CSIRO studying the virus’s behaviour and testing for potential treatments using a virus grown in the lab – the first in the world.

The research will aim to understand if vaccines developed for the virus work and are safe, with studies to be conducted at CSIRO’s high-containment Australian Animal Health Laboratory facility in Geelong.
Evacuations

Doctors are rushing to prepare Christmas Island for coronavirus evacuees currently locked down in Wuhan.

More than 600 Australian citizens have registered for advice or assistance ahead of the planned evacuation to Christmas Island, where the evacuees will be quarantined for 14 days.

Home Affairs Minister Peter Dutton has been forced to defend the heavily criticised plan to send evacuees to the island, where the federal government has held asylum seekers in detention.

“The government is making a decision here to get Australians out of a very difficult position, but our responsibility otherwise is to make sure we keep Australians safe,” he told reporters in Canberra on Thursday.

Australian Medical Association boss Tony Bartone said there were better alternatives to Christmas Island.

Some medical specialists have suggested using the Woodside army barracks near Adelaide and another facility just north of Katherine in the NT.

Christmas Island administrator Natasha Griggs said residents had expressed some concerns but had been assured that all necessary measures had been put in place to ensure the safety of locals.

“By and large, the Christmas Island residents understand that this is a humanitarian mission and they’re generally supportive,” she said.

Four cases of coronavirus have been confirmed in NSW, three cases have been confirmed in Victoria and two cases have been confirmed in Queensland.

Of the four NSW cases, two men have been discharged from hospital after tests showed they were no longer infectious.

Economic impact

A WHO global emergency declaration could further spook markets, already shuddering at the ripple effects of damage to China’s economy.

Chris Weston, head of research at Melbourne brokerage Pepperstone, said an emergency declaration by the WHO could alarm investors.

“The fear is that they (the WHO) might raise the alarm bells … so people are taking money off the table,” he said.

The 2002-2003 Severe Acute Respiratory Syndrome also came from China, killing about 800 people and costing the global economy an estimated $US33 billion ($49 billion).

Economists fear the impact could be bigger this time as China now accounts for a larger share of the world economy.

CORONA VIRUS

Hi folks,

This is from a doctor in Hong Kong who consulted with his friend (who currently works on SARS prevention research) on some effective ways to prevent the Coronavirus. It was originally written in Cantonese style Chinese so I used my best attempt to translate it into English for you guys. Worth a read.

About the virus:

1. It is pretty large in size (cell is about 400-500nm diameter), so any normal mask (not just the  N95 feature) should be able to filter it out. However, when someone who's infected sneezes in front of you, it will take a great 3 meters (about 10 feet) before it drops to the ground and is no longer airborne.

2. When the virus drops on metal surface, it will live for at least 12 hours. So remember if you come in contact with any metal surface, wash your hands with soap thoroughly.

3. The virus can remain active on fabric for 6-12 hours. Normal laundry detergent should kill the virus. But if you are really worried, you can add some non-chlorine bleach or oxygen bleach . For winter clothing that does not require daily washing, you can put it out under the sun to kill the virus.

About the symptoms of the pneumonia caused by Coronavirus:

1. It will first infect the throat, so the throat will have the dry sore throat feeling which will last for 3 to 4 days

2. Then the virus will blend into the nasal fluid and drips into the trachea and enter the lungs, causing pneumonia. This process will take 5 to 6 days. 

3. With pneumonia, comes high fever and difficulty in breathing. The nasal congestion is not like the normal kind. You will feel like you are drowning in water. It's important to go seek immediate medical attention if you feel like this.

About prevention:

1. The most common way of getting infected is by touching things in public, so you must wash your hands frequently. The virus can only live on your hands for 5-10 mins, but a lot can happen in those 5-10 mins (you can rub your eyes or pick your nose unwittingly lol).

2. Aside from washing your hands frequently, you can gargle with Betadine Sore Throat Gargle to eliminate or minimize the germs while they are still in your throat (before dripping down to your lungs).

Some of you may not agree with this, but at least you have read it and know some key info about the virus. Hope this helps!

Cheers

Differences between bacterial and viral infection

Differences between bacterial and viral infection

While bacteria and viruses can both cause mild to serious infections, they are different from each other. This is important to understand, because bacterial and viral infections must be treated differently. Misusing antibiotics to treat viral infections contributes to the problem of antibiotic resistance.

Bacteria vs viruses

Bacteria and viruses are too tiny to be seen by the naked eye, can cause similar symptoms and are often spread in the same way, but that’s where the similarities end.

A bacterium is a single, but complex, cell. It can survive on its own, inside or outside the body.
Most bacteria aren’t harmful. In fact, we have many bacteria on and inside our body, especially in the gut to help digest food.

Viruses are smaller and are not cells. Unlike bacteria, they need a host such as a human or animal to multiply. Viruses cause infections by entering and multiplying inside the host’s healthy cells.


Bacterial vs viral infection

As the names suggest, bacteria cause bacterial infections, and viruses cause viral infections.

It is important to know whether bacteria or viruses cause an infection, because the treatments differ. 

Examples of bacterial infections include whooping cough, strep throat, ear infection and urinary tract infection (UTI).

Viral infections include the common cold, flu, most coughs and bronchitis, chickenpox and HIV/AIDS.

It can be difficult to know what causes an infection, because viral and bacterial infections can cause similar symptoms. Your doctor may need a sample of your urine, stool and blood for a ‘culture’ test to have the bugs identified under a microscope.

Treatment of bacterial and viral infection

Bacterial infection treatment


Doctors usually treat bacterial infections with antibiotics. They either kill bacteria or stop them multiplying.

But since antibiotic resistance is a growing problem, antibiotics may be prescribed only for serious bacterial infections.

Viral infection treatment
The treatment of viral infections can include:
managing symptoms, such as honey for coughs and warm fluids like chicken soup for oral hydration, paracetamol to relieve fever
stopping viral reproduction using antiviral medicines, such as medicines for HIV/AIDS and cold sores preventing infection in the first place, such as vaccines for flu and hepatitis

Remember: Antibiotics won’t work for viral infections.
