Influenza (flu) is highly infectious. 2 main viruses cause flu, Influenza A and B. Flu can be more serious than a cold and severe cases can result in breathing difficulties and pneumonia. People can die from flu. Flu can occur throughout the year, but it is most common in Autumn and Winter.
Symptoms include:
- Fever and chills
- Cough, sore throat and runny or stuffy nose
- Muscle aches, joint pains, headaches and fatigue (feeling very tired)
- Nausea, vomiting and diarrhoea (more common in children than adults).
Symptoms may last for more than a week. Some people may have a very mild illness (those who have some immunity from a previous infection or those who have been vaccinated), whilst others may become very unwell. Those particularly at high risk of flu, include the elderly, the very young, pregnant women, people over 65 years of age, Aboriginal and Torres Strait Islanders and those who are immunocompromised (those with a weaker immune system).
Diagnosis and treatment
Flu is diagnosed with a PCR (nose and throat) swab. If you become unwell, and you suspect you may have flu, it is important to speak with your GP to see if you should be tested.
Antivirals may be offered to patients with severe disease and to people at higher risk of severe disease from influenza. Antiviral treatment should be started as soon as possible after the onset of symptoms, ideally within 48 hours of symptom onset.
Get vaccinated
You should talk to your GP and rheumatologist about receiving a flu vaccine. A flu vaccine will not give you the flu, nor will it prevent you from catching flu, but it will prevent severe disease or complications from developing, particularly if you are at high risk. Anyone over the age of 6 months can be vaccinated against flu.
