Understanding Flu
What Is Flu?
The Flu is a contagious respiratory illness caused by influenza viruses (Type A or Type B) that infect the respiratory tract. During the winter season, influenza makes up the majority of diseases.
Flu can manifest in headaches, sluggishness, body aches and a runny nose. It can also produce deadly, serious or fatal symptoms, including:
- Kidney or other organ damage
- Inflammation of the heart, brain or muscles
- Pneumonia
- Death
The influenza virus is the primary cause of the flu. Keep in mind that there are many strains of the flu virus, and they constantly evolve each year.
Identifying Flu Symptoms
Once acquired, it usually takes one to three days for flu symptoms to show.
Then, it persists for approximately 7 days, or even more.
Flu affects everyone differently. Some might feel seriously ill and bedridden, while others hardly show any signs of infection.
Here are some of the symptoms flu exhibits:
- Fever and chills
- Body aches
- Sore throat, coughing
- Sneezing or runny nose
- Diarrhea and vomiting
Flu can develop into something more serious, which includes:
- Heart and other organ failures
- Ear infection
- Brain inflammation and damage
- Croup
- Bronchitis
- Pneumonia
- Death
Who Is At Risk?
Flu is a disease that can affect anyone, regardless of age.
People who are most susceptible to catching the flu virus include:
- Individuals who haven't had a flu vaccination
- Babies
- Pregnant women and their unborn baby
- Those who are 65 and older
- Torres Strait Islanders and Aboriginals (Aboriginal people and influenza)
- Smokers (Quit smoking Now)
- Individuals who have weakened immune systems
- Obese individuals
Medical conditions that could lead to acquiring a deadly form of flu include:
- Diabetes
- Kidney or Liver disease
- Nervous system conditions, like multiple sclerosis
- Down syndrome
- Blood diseases
- Lung disease
- Metabolic disorders
It's important to note that those who have had flu shots can still get sick with the flu virus, but the risk and severity of the disease, including its symptoms, will be significantly reduced.
How Can You Get The Flu?
- Touching a contaminated surface that contains the flu virus, then subsequently touching your nose, eyes or mouth.
- Contact with an infected person's fluids when he or she sneezes or coughs.
- Breathing in an infected person's cough or sneeze.
Flu is highly contagious, which means it can easily spread through families, schools, the workplace and communities.
How Can You Stay Protected From Flu?
Flu vaccination is still the best form of protection against the influenza virus.
Vaccines can lessen the risk and seriousness of the disease. Because the influenza virus constantly changes through a process called antigenic drift, every year, there are new flu vaccines to protect individuals against the new strains.
Did you know you can stop the spread of flu even if you're sick?
Here are a few best practices:
- Frequent hand-washing.
- Cover up when you cough or sneeze.
- Stay at home and away from populated areas such as schools, workplaces, and malls.
