In December 2019, an outbreak of a novel coronavirus occurred in Wuhan, Hubei Province, China. The virus quickly spread throughout Hubei Province and to other provinces in mainland China, before spreading internationally. Quarantine measures implemented in mainland China and border control measures including travel restrictions implemented internationally, contained the virus and delayed significant spread. However, by the end of February 2020, cases had been reported in 57 countries with rapid increases in Iran, South Korea and Italy.
On 11 March 2020, the World Health Organisation (WHO) declared COVID-19 as a pandemic.
As the coronavirus pandemic spreads around the world, many of us have concerns and questions.
What are the symptoms? How should you prepare? How is it spread? – we hope the information below answers all your questions on the disease outbreak spreading across the world.
What Is a Coronavirus?
Coronaviruses (CoV) are a large family of viruses that cause illness ranging from the common cold to more severe diseases such as Middle East Respiratory Syndrome (MERS-CoV) and Severe Acute Respiratory Syndrome (SARS-CoV). A novel coronavirus (nCoV) is a new strain that has not been previously identified in humans.
Coronaviruses are zoonotic, meaning they are transmitted between animals and people. Detailed investigations found that SARS-CoV was transmitted from civet cats to humans and MERS-CoV from dromedary camels to humans. Several known coronaviruses are circulating in animals that have not yet infected humans.
What is COVID-19?
COVID-19 is the infectious disease caused by the most recently discovered coronavirus. This new virus and disease were unknown before the outbreak began in Wuhan, China, in December 2019.
How did the outbreak start?
The source of the coronavirus is believed to be a “wet market” in Wuhan which sold both dead and live animals including fish and birds.
Such markets pose a heightened risk of viruses jumping from animals to humans because hygiene standards are difficult to maintain if live animals are being kept and butchered on site. Typically, they are also densely packed.
The animal source of the latest outbreak has not yet been identified, but the original host is thought to be bats. Bats were not sold at the Wuhan market but may have infected live chickens or other animals sold there.
Bats are host to a wide range of zoonotic viruses including Ebola, HIV and rabies.
As at 06:30 hrs on 14 March 2020, there were 197 confirmed cases of coronavirus (COVID-19), including 3 deaths, in Australia. Of the 197 Australian cases reported, 27 of these cases are reported to have recovered.
Across the world
Across the world, there have been more than 140,500 confirmed cases of coronavirus (COVID-19) and more than 5,300 reported deaths.
Of confirmed cases reported globally, the case fatality rate is approximately 3.7%.
What are the symptoms of COVID-19?
The most common symptoms of COVID-19 are fever, tiredness, and dry cough. Some patients may have aches and pains, nasal congestion, runny nose, sore throat or diarrhea. These symptoms are usually mild and begin gradually. Some people become infected but don’t develop any symptoms and don’t feel unwell. Most people (about 80%) recover from the disease without needing special treatment. Around 1 out of every 6 people who gets COVID-19 becomes seriously ill and develops difficulty breathing. Older people, and those with underlying medical problems like high blood pressure, heart problems or diabetes, are more likely to develop serious illness. People with fever, cough and difficulty breathing should seek medical attention.
How does COVID-19 spread?
People can catch COVID-19 from others who have the virus. The disease can spread from person to person through small droplets from the nose or mouth which are spread when a person with COVID-19 coughs or exhales. These droplets land on objects and surfaces around the person. Other people then catch COVID-19 by touching these objects or surfaces, then touching their eyes, nose or mouth. People can also catch COVID-19 if they breathe in droplets from a person with COVID-19 who coughs out or exhales droplets. This is why it is important to stay more than 1 meter (3 feet) away from a person who is sick.
What can I do to protect myself and prevent the spread of disease?
Protection measures for everyone
Stay aware of the latest information on the COVID-19 outbreak, through the Australian Government Department of Health. Many countries around the world have seen cases of COVID-19 and several have seen outbreaks. Authorities in China and some other countries have succeeded in slowing or stopping their outbreaks. However, the situation is unpredictable so check regularly for the latest news.
You can reduce your chances of being infected or spreading COVID-19 by taking some simple precautions:
- Regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water.
Why? Washing your hands with soap and water or using alcohol-based hand rub kills viruses that may be on your hands.
- Maintain at least 1 metre (3 feet) distance between yourself and anyone who is coughing or sneezing.
Why? When someone coughs or sneezes they spray small liquid droplets from their nose or mouth which may contain virus. If you are too close, you can breathe in the droplets, including the COVID-19 virus if the person coughing has the disease.
- Avoid touching eyes, nose and mouth.
Why? Hands touch many surfaces and can pick up viruses. Once contaminated, hands can transfer the virus to your eyes, nose or mouth. From there, the virus can enter your body and can make you sick.
- Make sure you, and the people around you, follow good respiratory hygiene. This means covering your mouth and nose with your bent elbow or tissue when you cough or sneeze. Then dispose of the used tissue immediately.
Why? Droplets spread virus. By following good respiratory hygiene you protect the people around you from viruses such as cold, flu and COVID-19.
- Stay home if you feel unwell. If you have a fever, cough and difficulty breathing, seek medical attention and call in advance. Follow the directions of your local health authority.
Why? National and local authorities will have the most up to date information on the situation in your area. Calling in advance will allow your health care provider to quickly direct you to the right health facility. This will also protect you and help prevent spread of viruses and other infections.
- Keep up to date on the latest COVID-19 hotspots (cities or local areas where COVID-19 is spreading widely). If possible, avoid traveling to places – especially if you are an older person or have diabetes, heart or lung disease.
Why? You have a higher chance of catching COVID-19 in one of these areas.
Should I worry about COVID-19?
Illness due to COVID-19 infection is generally mild, especially for children and young adults. However, it can cause serious illness: about 1 in every 5 people who catch it need hospital care. It is therefore quite normal for people to worry about how the COVID-19 outbreak will affect them and their loved ones.
We can channel our concerns into actions to protect ourselves, our loved ones and our communities. First and foremost among these actions is regular and thorough hand-washing and good respiratory hygiene. Secondly, keep informed and follow the advice of the local health authorities including any restrictions put in place on travel, movement and gatherings.
Who is at risk of developing severe illness?
While we are still learning about how COVID-2019 affects people, older persons and persons with pre-existing medical conditions (such as high blood pressure, heart disease, lung disease, cancer or diabetes) appear to develop serious illness more often than others.
Are antibiotics effective in preventing or treating the COVID-19?
No. Antibiotics do not work against viruses, they only work on bacterial infections. COVID-19 is caused by a virus, so antibiotics do not work. Antibiotics should not be used as a means of prevention or treatment of COVID-19. They should only be used as directed by a physician to treat a bacterial infection.
Is there a vaccine, drug or treatment for COVID-19?
Not yet. To date, there is no vaccine and no specific antiviral medicine to prevent or treat COVID-2019. However, those affected should receive care to relieve symptoms. People with serious illness should be hospitalized. Most patients recover thanks to supportive care.
Possible vaccines and some specific drug treatments are under investigation. They are being tested through clinical trials. The World Health Organisation is coordinating efforts to develop vaccines and medicines to prevent and treat COVID-19.
The most effective ways to protect yourself and others against COVID-19 are to frequently clean your hands, cover your cough with the bend of elbow or tissue, and maintain a distance of at least 1 meter (3 feet) from people who are coughing or sneezing.
Is COVID-19 the same as SARS?
No. The virus that causes COVID-19 and the one that caused the outbreak of Severe Acute Respiratory Syndrome (SARS) in 2003 are related to each other genetically, but the diseases they cause are quite different.
SARS was more deadly but much less infectious than COVID-19. There have been no outbreaks of SARS anywhere in the world since 2003.
Should I wear a mask to protect myself?
Only wear a mask if you are ill with COVID-19 symptoms (especially coughing) or looking after someone who may have COVID-19. Disposable face mask can only be used once. If you are not ill or looking after someone who is ill then you are wasting a mask. There is a world-wide shortage of masks, so the World Health Organisation urges people to use masks wisely.
The most effective ways to protect yourself and others against COVID-19 are to frequently clean your hands, cover your cough with the bend of elbow or tissue and maintain a distance of at least 1 meter (3 feet) from people who are coughing or sneezing.
How long does the virus survive on surfaces?
It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).
If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose.
At the same time, the World Health Organisation is reportedly encouraging people to use as many digital payment options as possible. Viruses can survive on hard surfaces like coins for days in some cases. Australian dollars, a blend of fabric and paper, are harder for viruses to stick to.
Is it safe to receive a package from any area where COVID-19 has been reported?
Yes. The likelihood of an infected person contaminating commercial goods is low and the risk of catching the virus that causes COVID-19 from a package that has been moved, travelled, and exposed to different conditions and temperature is also low.
Is it best to cancel routine doctor and dental appointments?
No, you still have to take care of yourself. We have taken every safety measure to ensure you are protected from the virus.
What is involved in testing for the coronavirus? Is it the same as when they do a nasal swab for influenza?
To collect a sample for a diagnostic test for SARS-CoV-2, the virus that causes the COVID-19 disease, doctors typically use the same method of collection as they would for influenza: a nasopharyngeal swab. For this swab, a tiny Q-tip on plastic or a wire stem is put up your nose about 3 or 4 inches.
A doctor may also do a throat swab. In some cases, if you have a “wet” cough, a doctor may also have you cough up some phlegm into a collection cup. These specimen are then packed with ice and shipped to a lab for testing.
To determine if someone has recovered from the coronavirus, at least two different nasal swabs taken at least 24 hours apart must test negative.
Is there anything I should not do?
The following measures ARE NOT effective against COVID-2019 and can be harmful:
- Wearing multiple masks
- Taking antibiotics
In any case, if you have fever, cough and difficulty breathing seek medical care early to reduce the risk of developing a more severe infection and be sure to share your recent travel history with your health care provider.
