What are coronaviruses? [bg_collapse view=”link” color=”#4a4949″ icon=”arrow” expand_text=”Show More” collapse_text=”Show Less” ] Coronaviruses are a large family of viruses. Some coronaviruses cause illness in humans and others cause illness in animals, such as bats, camels, and civets. Human coronaviruses generally cause mild illness, such as the common cold. Rarely, animal coronaviruses can evolve to infect and spread among humans, causing severe diseases such as Severe Acute Respiratory Syndrome (SARS) which emerged in 2002, and Middle East Respiratory Syndrome (MERS) which emerged in 2012.
What is the COVID-19 virus? [bg_collapse view=”link” color=”#4a4949″ icon=”arrow” expand_text=”Show More” collapse_text=”Show Less” ]COVID-19 is a new strain of coronavirus that has not been previously identified in humans. It was first identified in Wuhan, Hubei Province, China, where it has caused a large and ongoing outbreak. It has since spread more widely in China. Cases have since been identified in several other countries. The COVID-19 virus is closely related to a bat coronavirus.
There is much more to learn about how COVID-19 is spread, its severity, and other features associated with the virus; epidemiological and clinical investigations are ongoing.
Outbreaks of new coronavirus infections among people are always a public health concern. The situation is evolving rapidly.
How is the virus spread? [bg_collapse view=”link” color=”#4a4949″ icon=”arrow” expand_text=”Show More” collapse_text=”Show Less” ] Human coronaviruses are spread from someone infected with COVID-19 virus to other close contacts with that person through contaminated droplets spread by coughing or sneezing, or by contact with contaminated hands, surfaces or objects.
The time between when a person is exposed to the virus and when symptoms first appear is typically 5 to 6 days, although may range from 2 to 14 days. For this reason, people who might have been in contact with a confirmed case are being asked to self-isolate for 14 days.
Most COVID-19 cases appear to be spread from people who have symptoms. A small number of people may have been infectious before their symptoms developed.
How long does COVID-19 last on surfaces? [bg_collapse view=”link” color=”#4a4949″ icon=”arrow” expand_text=”Show More” collapse_text=”Show Less” ]According to the World Health Organization, 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 a common household 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.
What are the symptoms? [bg_collapse view=”link” color=”#4a4949″ icon=”arrow” expand_text=”Show More” collapse_text=”Show Less” ] Patients may have fever, chills or sweats, cough, sore throat, runny nose, shortness of breath, loss of sense of smell or taste and other symptoms. In certain circumstances headache, muscle soreness, nausea, vomiting and diarrhoea may also be symptoms.
In more severe cases, infection can cause pneumonia with severe acute respiratory distress.
Is there a cure or vaccine? [bg_collapse view=”link” color=”#4a4949″ icon=”arrow” expand_text=”Show More” collapse_text=”Show Less” ]There are no vaccines that protect against COVID-19.
There is no specific treatment for COVID-19. Early diagnosis and general supportive care are important. Most of the time, symptoms will resolve on their own. People who have serious disease with complications can be cared for in hospital.
Should I get tested for COVID-19? [bg_collapse view=”link” color=”#4a4949″ icon=”arrow” expand_text=”Show More” collapse_text=”Show Less” ]
Patients who meet the following clinical criteria should be tested:
Fever OR chills in the absence of an alternative diagnosis that explains the clinical presentation*
Acute respiratory infection (e.g. cough, sore throat, shortness of breath, runny nose or anosmia)
Note: In addition, testing is recommended for people with new onset of other clinical symptoms consistent with COVID-19** AND who are close contacts of a confirmed case of COVID-19; who have returned from overseas in the past 14 days; or who are healthcare or aged care workers
*Clinical discretion applies including consideration of the potential for co-infection (e.g. concurrent infection with SARS-CoV-2 and influenza)
**headache, myalgia, stuffy nose, nausea, vomiting, diarrhoea
This testing can take a few days to complete and report back.
