Influenza
Usually called the flu, influenza is caused by a virus and spreads from person to person through the air by coughing, sneezing or talking, and by touching a person’s hands, a surface or object.
How does it infect?
The flu virus infects your breathing through the nose, throat and sometimes your lungs. It differs from a cold as the symptoms such as fever, sore throat and muscle aches develop quickly and last about a week. You can have a very mild to a severe flu, and at times you can develop complications such as pneumonia and bronchitis which require a hospital visit. Sometimes these complications can lead to death.
If you have other medical conditions such as diabetes, it can make them worse. There is a need to get vaccinated every year because the viruses circulating in the community are always changing and immunity from the vaccine does not last a long time. It is especially important that people at risk get a flu shot each year.

Colds
The runny nose, headache, sore throat or ‘stuffy’ feeling you get during a common cold is caused by one of many viruses – often a rhinovirus – and they can infect your nose, throat, sinuses and airways. The symptoms are usually a blocked or runny nose, sneezing, sore throat and a cough. You might also have a fever, mild aching muscles and general tiredness. These symptoms usually last for less than a week.
Steps to prevent the spread?
There are steps you can take when you have a cold or flu, to help prevent spreading illness:
- try to stay away from other people to prevent the virus from spreading;
- cover your mouth when coughing or sneezing and wash your hands;
- throw away tissues as soon as you have used them and wash your hands;
- stay home from work to prevent spreading it to others and keep children home from school.
