澳大利亚现在已经累计确诊449例！最近Google Trend 筛选出来几个问题，也是全球人们最关心的关于新冠病毒的问题，看看这些问题是否也是你想问的呢？
There are two things doctors take into consideration when it comes to deciding whether you need to be tested: your symptoms and your history (the likelihood that you have been exposed to the illness).
Symptoms of novel coronavirus can feel like a cold or flu and include:
a dry cough 干咳
sore throat 嗓子疼
a runny nose 流鼻涕
shortness of breath 气短
diarrhea and nausea have also been reported but are less common 腹泻以及恶心
At this stage, testing is recommended only for those who have symptoms and may have encountered the illness. This includes people who have returned from overseas within the last 14 days or those who have been in contact with someone known to have the illness.
If you are concerned that you or someone in your family may have coronavirus symptoms and should get tested, then it's best to call coronavirus health information hotline on 1800 020 080 for advice.
This hotline has been expanded to a 24/7 operation that will triage （分流）people to a fever clinic or suggest they phone their local GP for follow up.
If you are going to you visit your doctor, call ahead. This will ensure the clinic can take steps to protect staff and other patients, and also check whether you're likely to be at risk.
Doctors may ask if you've recently been in countries affected by coronavirus, such as mainland China, Iran, South Korea or Italy, or if you have been in contact with someone who has a confirmed or suspected case of the disease.
"It is important that [the individual] calls ahead of time to book an appointment and tell the medical professional about their symptoms, travel history and any recent close contact with someone who has COVID-19," said a spokesperson from the Department of Health.
If you do go to get tested, ask your doctor what precautions to take — whether you should wear a mask, for example.

The COVID-19 test can be ordered by a specialist coronavirus clinic, your local GP or a hospital emergency department.
The Federal Government has announced plans to create up to 100 coronavirus pop-up clinics across the country.
But these testing facilities vary state by state, so it's best to first be in touch with the coronavirus health information hotline on 1800 020 080 for advice.
Testing methods may include a blood test, a swab test inside your nose or in the back of your throat, or a sputum (mix of saliva and mucus) test.
Remember, you may still need a GP referral before attending new clinics, so be sure to check first.
Medical and mental health staff will soon be able to bulk-bill sessions conducted over video conferencing services like FaceTime, Skype and WhatsApp.

Unfortunately there isn't a clear answer to this question.
Modelling by Australian scientists, including James McCaw a the University of Melbourne, may hold some clues.
He said it was likely COVID-19 would become a permanent, seasonal disease in humans after this initial epidemic.
"Just as for [2009 swine flu], the virus will cause a large initial epidemic, perhaps followed by subsequent waves of infection, and then reduce to low levels," Professor McCaw said.
"But it is unlikely to truly disappear, just like seasonal influenza doesn't truly disappear each year.
"This is different to SARS — which we truly eliminated because we successfully controlled it before it could fully establish itself in the human population."
But other experts have differing views.
"My personal opinion and my hope is that .... [the COVID-19 outbreak] will disappear with time, rather than becoming established in the population," William Rawlinson, senior medical virologist with NSW Health Pathology told the ABC last week.
WA Premier Mark McGowan has said modelling indicated coronavirus would be spreading in Australia in April or May, and the peak of the epidemic would happen in August, and Professor McCaw said these time frames were consistent with the models he's been working on.

It's a question a lot of people have been asking, and science is starting to give us a clearer picture of the answer.
One study that brought together data from 22 previous studies on coronaviruses(but not this new 2019 strain) found human coronaviruses could theoretically last on surfaces at room temperature for up to nine days.
That sounds like a long time, but a lot of factors come into play, tweeted Angela Rasmussen, a virologist at Columbia University in the US.
Some of these factors include:
The type of surface: Viruses survive on shiny, hard surfaces longer than soft ones
Whether it's exposed to sunlight: UV radiation kills viruses
Temperature and humidity: Viruses last longer at lower temperatures and lower humidity
The study concluded that disinfecting surfaces with 0.1 per cent sodium hypochlorite or 62–71 per cent ethanol significantly reduced the infectivity of coronavirus on surfaces, and that the authors expected a similar effect against the SARS-CoV-2.
Another crucial way to avoid getting infected from touching a contaminated surface? Keep your hands clean and don't touch your face. Here's a reminder on how to wash your hands effectively.
Testing methods for the coronavirus may include a blood test, a swab test inside your nose or in the back of your throat, or a sputum (mix of saliva and mucus) test.
This won't last long, but the time it takes to get results may vary according to your location.
A Department of Health spokesperson said the timeframe depends on where the specimen is collected, among other factors.
Patients are asked to isolate themselves while waiting for a result.
The recommendations about testing and quarantine are being updated daily as the situation evolves.
