Last year, due a number of factors associated with how we managed COVID, the number of people affected by the flu was significantly less than usual. In 2019 in Australia, there were more than 300,000 people diagnosed with the flu, compared to only about 21,000 nationally for the same time last year.

While the attention on COVID is vital, we cannot forget the risks associated with the flu. With the colder weather fast approaching, there comes an increased risk of viruses spreading through the community. Older people can be particularly susceptible, which can lead to complications, so it is important to keep an eye on symptoms – and have a COVID test.

The flu can be deadly, with more than 800 deaths reported around Australia from the flu in 2019, compared to 36 last year. Fortunately, the measures taken last year to contain the spread of COVID had a significant effect in also reducing transmission of the flu.

Understanding the difference between colds and the flu is useful, as they are caused by different viruses. While both are unpleasant, the flu can be much more serious for vulnerable people.

The common cold affects the nose, throat and upper airways, producing symptoms such as a blocked or runny nose, sore throat, coughing, fever and general congestion. A cold can be caused by over 200 different viruses and, unfortunately, there is no vaccination to protect against it. Flu symptoms are very similar, however may be more intense and appear quicker. The flu may also be accompanied by chills, which is less common for a cold.

It is critical to take steps to minimise spreading viruses to others, and the best way to do this is to practise good hygiene. An annual flu vaccination is also a good idea to prevent catching the flu virus – your GP, local pharmacy or council can provide these and now is the ideal time to be immunised. It is important to remember, without having the vaccination, you will be unable to visit an aged care facility.

As we head into winter and continue to battle the new world of COVID, remember to stay aware of the risks of other illnesses such as cold and flu.
