Frequently asked questions – Coronavirus disease (COVID-19)
What is a coronavirus and COVID-19?
Coronaviruses are a large family of viruses known to cause respiratory infections. These can range from the common cold to more serious diseases such as Severe Acute Respiratory Syndrome (SARS). This new coronavirus originated in Hubei Province, China and the disease caused by the virus is named COVID-19.
How is this coronavirus spread?
COVID-19 is most likely to spread from person-to-person through:
- Direct close contact with a person while they are infectious (showing symptoms) or in the 24 hours before their symptoms appeared
- Close contact (shaking hands) with a person who has a confirmed infection who coughs or sneezes
- Touching objects or surfaces (such as door handles or tables) contaminated from a cough or sneeze from a person with a confirmed infection, and then touching your mouth or face
What are the symptoms of COVID-19?
The symptoms of COVID-19 are similar to other colds and flus and include:
- Sore throat
- Difficulty breathing
While coronavirus is of concern, it is important to remember that most people displaying these symptoms are likely suffering with a cold or other respiratory illness – not coronavirus.
What do I do if I develop symptoms?
If you develop symptoms within 14 days of arriving in Australia or within 14 days of last contact with a confirmed case, you should arrange to see your doctor for urgent assessment.
You should telephone the health clinic or hospital before you arrive and tell them your travel history or that you have been in contact with a confirmed case of coronavirus.
You must remain isolated either in your home, hotel or a health care setting until public health authorities inform you it is safe for you to return to your usual activities.
Should I be tested for COVID-19?
You will only be tested if your doctor decides you meet the criteria:
- You have returned from overseas in the past 14 days and you develop respiratory illness with or without fever
- You have been in close contact with a confirmed COVID-19 case in the past 14 days and you develop respiratory illness with or without fever
- You have severe community-acquired pneumonia and there is no clear cause
- You are a healthcare worker who works directly with patients and you have a respiratory illness and a fever
It is important to remember that many people with symptoms similar to COVID-19 will not have the virus.
Who needs to isolate?
All people who arrive in Australia from midnight 15 March 2020, or think they may have been in close contact with a confirmed case of coronavirus, are required to self-isolate for 14 days.
Someone I live with is getting tested for COVID-19. Should I self-isolate and get tested as well?
If a household member is a suspected case, you may need to be isolated. This will be determined by your public health unit on a case-by-case basis. Your public health unit will contact you if you need to isolate.
What does isolate in your home mean?
If you have been diagnosed with COVID-19, you must stay at home to prevent it spreading to other people. You might also be asked to stay at home if you may have been exposed to the virus. Staying at home means you:
- Do not go to public places such as work, school, shopping centres, childcare or university
- Ask someone to get food and other necessities for you and leave them at your front door
- Do not let visitors in — only people who usually live with you should be in your home
You do not need to wear a mask in your home. If you need to go out to seek medical attention, call ahead first, and wear a surgical mask (if you have one) to protect others. You should stay in touch by phone and on-line with your family and friends.
What is social distancing?
Social distancing is one way to help slow the spread of viruses such as COVID-19.
Social distancing includes:
- staying at home when you are unwell
- avoiding large public gatherings if they’re not essential
- keeping a distance of 1.5 metres between you and other people whenever possible and minimising physical contact such as shaking hands
There’s no need to change your daily routine, but taking these social distancing precautions can help protect the people in our community who are most at risk.
Who is most at risk of a serious illness?
Some people who are infected may not get sick at all, some will get mild symptoms from which they will recover easily, and others may become very ill, very quickly. From previous experience with other coronaviruses, the people at most risk of serious infection are:
- People with compromised immune systems (e.g. cancer)
- Elderly people
- Aboriginal and Torres Strait Islander people, as they have higher rates of chronic illness
- People with diagnosed chronic medical conditions
- People in group residential settings
- People in detention facilities.
- Very young children and babies.*
*At this stage the risk to children and babies, and the role children play in the transmission of COVID-19, is not clear. However, there has so far been a low rate of confirmed COVID-19 cases among children, relative to the broader population.
How is the virus treated?
There is no specific treatment for coronaviruses. Antibiotics are not effective against viruses. Most of the symptoms can be treated with supportive medical care.
How can we help prevent the spread of coronavirus?
Practising good hand and sneeze/cough hygiene and keeping your distance from others when you are sick is the best defence against most viruses.
- Wash your hands frequently with soap and water, before and after eating, and after going to the toilet
- Cover your cough and sneeze, dispose of tissues, and use alcohol-based hand sanitiser
- If unwell, avoid contact with others (stay more than 1.5 metres from people)
- Exercise personal responsibility for social distancing measures
