COVID-19

DEFINITION

COVID-19 is a respiratory illness caused by a new form of coronavirus.

WHAT IS A CORONAVIRUS?

Coronaviruses form a large family of viruses that can cause a range of illnesses. These include the common cold as well as more serious diseases like SARS (severe acute respiratory syndrome) and MERS (Middle East respiratory syndrome). COVID-19 is a newly discovered coronavirus.

Many animals also have coronavirus-related illnesses. When one of those viruses mutates and passes onto humans, the disease can be more severe because the human body has not developed immunity to it. Both the SARS and MERS diseases are examples of this happening in recent years. 1

WHO IS AT RISK?

The people most at risk of getting the virus are those who: 2

  • have been to a country or area in the last 14 days that has a high risk of COVID-19
  • have been in close contact with someone who is a confirmed case of COVID-19
  • are in correctional and detention facilities
  • are in group residential settings

The following people are at increased risk of developing serious illness if they get COVID-19:

  • Aboriginal and Torres Strait Islander people, 50 years and older, with one or more chronic medical conditions
  • those 70 years or older or 65 years and older with chronic medical conditions
  • those with a chronic condition or compromised immune system
  • people living in an aged care facility
  • people with a disability

DELTA VARIANT

The COVID-19 Delta variant was first identified in December 2020. Within a matter of months, this particular variant spread to over 98 countries around the world. Delta is 40-60 percent more transmissible or contagious than the alpha strain of COVID-19.

Studies are underway and initial data suggests the Delta variant might cause more severe illness than previous strains in unvaccinated people.

Individuals infected with the Delta variant, including fully vaccinated people, can transmit it to others. Fully vaccinated people, however, appear to be infectious for a shorter period. The greatest risk of transmission is among unvaccinated people who are much more likely to contract, and therefore transmit the virus.3

SIGNS AND SYMPTOMS

Symptoms of COVID-19 can range from mild illness to pneumonia. Some people will recover easily, and others may get very sick very quickly. People with COVID-19 may experience symptoms such as: 4

  • fever
  • coughing
  • sore throat
  • shortness of breath

Other symptoms can include:

  • runny nose
  • acute blocked nose (congestion)
  • headache
  • muscle or joint pains
  • nausea
  • diarrhoea
  • vomiting
  • loss of sense of smell
  • altered sense of taste
  • loss of appetite
  • fatigue

If you are experiencing any of these symptoms, seek medical advice and get tested.

PREVENTION 

A vaccine teaches your body to fight the infection by stopping you from catching COVID-19, or at least making it less deadly.

The Australian Government has secured COVID-19 vaccine from manufacturers Pfizer (Comirnaty) and AstraZeneca (Vaxzevria). The Moderna vaccine is expected to be rolled-out in mid-September. 5

COVID-19 vaccines will be free for everyone living in Australia. You will not need a prescription from a GP to get vaccinated. The COVID-19 vaccination is voluntary. Vaccination protects against serious illness, hospitalisation and death from COVID-19. The vaccine you receive may depend on: 6

  • availability
  • the clinical guidelines that determine who each vaccine is safe for

You can also reduce your chances of being infected with or spreading COVID-19 by taking some simple precautions: 7

  • regularly and thoroughly clean your hands with an alcohol-based hand rub or wash them with soap and water
  • maintain at least 1.5 metres distance between yourself and others
  • avoid going to crowded places
  • avoid touching your eyes, nose and mouth
  • cover your mouth and nose with your bent elbow or tissue when you cough or sneeze. Dispose of the used tissue immediately and wash your hands
  • face masks help stop droplets spreading when someone speaks, laughs, coughs, or sneezes, including someone who has coronavirus (COVID-19) but feels well. Face masks are an additional protective physical barrier to protect you and your loved ones
  • stay at home and self-isolate even with minor symptoms such as cough, headache, mild fever, until you recover. Have someone bring you supplies. If you need to leave your house, wear a mask to avoid infecting others
  • if you have a fever, cough and difficulty breathing, seek medical attention, but call by telephone in advance if possible and follow the directions of your local health authority

SAFETY CONCERNS

A rare but serious side effect has been identified, involving thrombosis (clotting) with thrombocytopenia (low blood platelet count) in a small number of people following vaccination with the COVID-19 AstraZeneca (Vaxzevria) vaccine. 

The Australian Technical Advisory Group (ATAGI) recommends that the COVID-19 Pfizer (Comirnaty) vaccine is preferred over the AstraZeneca (Vaxzevria) vaccine in adults aged under 60 years. The ATAGI also recommends that people under 60 years who have had their first dose of the AstraZeneca (Vaxzevria) vaccine should have their second dose. 8

COVID-19 vaccination is available through general practice respiratory clinics, and state and territory vaccination clinics. These sites have been expanded to participating general practices and to selected pharmacies as well.

WHO IS ELIGIBLE FOR COVID-19 VACCINATION?

Pfizer (Comirnaty) vaccine

Australians aged between 12 and 59 years are eligible for the Pfizer (Comirnaty) vaccine. 

Parents and guardians can book an appointment for a child aged 12-15 years to have the Pfizer (Comirnaty) vaccine at a GP, Commonwealth vaccination clinic or through the online COVID-19 Vaccine Eligibility Checker9.

AstraZeneca (Vaxzevria) vaccine
You can book an appointment for the AstraZeneca (Vaxzevria) vaccine if you are:

  • 60 years or older.
  • If you are aged 18-59 years of age, you can choose to receive the AstraZeneca (Vaxzevria) vaccine following an appropriate assessment of suitability by a qualified health professional; and if you provide verbal or written consent10

NOTES

Wearing a face mask protects you and your community by providing an additional physical barrier to coronavirus (COVID-19).  For a face mask to be effective, it must fit well and cover your nose and mouth. This means that face shields, bandanas, or scarves or loose snoods, loose buffs or loose neck gaiters on their own will not provide effective protection from COVID-19.

Call 1800 020 080 if you are seeking information on coronavirus (COVID-19) or help with the COVIDSafe app. This line operates 24 hours a day, seven days a week. If you need to get tested, you can:

  • attend a free COVID-19 respiratory clinic
  • contact your doctor and they will arrange the test, this may attract a fee

COVID-19 respiratory clinics are dedicated health centres located around the country, focusing on testing people with symptoms of respiratory infection.

TREATMENT OPTIONS

Vaccination is a safe and effective means of preventing serious illness and death from COVID-19. There is  no cure for COVID-19, however medical care can treat most of the symptoms. Seek medical attention and testing if:

  • you think you might have COVID-19
  • in the last 14 days you have been to a country or area with a high risk of COVID-19
  • you have been in close contact with someone with COVID-19

WHAT TO DO IF YOU HAVE COVID-19

If you have been diagnosed with COVID-19, stay at home. You may need to do this for up to 14 days to help reduce the possible spread of infection. Follow these steps:

  • stay at home and ask other people to get food and other necessities for you and leave them at your front door
  • rest, drink plenty of fluid, and eat nutritious food
  • only people who usually live with you should be in your home. Do not let in visitors
  • stay in a separate room from other family members and use a dedicated bathroom if possible
  • clean and disinfect frequently touched surfaces
  • if you need to leave home to seek medical attention, wear a surgical mask and practise regular hand washing to protect others12

PHARMACIST'S ADVICE

Ask your Pharmacist for advice.

  1. Ask your Pharmacist for the most up-to-date information about the COVID-19 vaccination.
  2. Ensure everyone in your family has enough medication at home. If any prescriptions are due for a refill, make sure you submit them to your Pharmacy.
  3. If you do become unwell, ask your Pharmacist if medical supplies can be delivered to your home.
  4. To help prevent spreading or contracting the virus, practise regular hand washing. Soap is available from your Pharmacy. Hand sanitiser gel may also be available and can be used if soap and water are not available.
  5. Surgical masks can help prevent the spread of infection. These are available from your Pharmacy.
  6. If you do become unwell, paracetamol or ibuprofen will help to control your fever. Make sure you have enough on hand for yourself and family members. Ask your Pharmacist for advice.
  7. It is also important to stay well hydrated. Powders and solutions containing electrolytes are available from your Pharmacy.
