What is the Flu?

Many people have likely encountered the contagious and widespread virus known as the flu, or influenza, at some point in their lives.


The flu symptoms are frequently mistaken for those of a cold, but they are considerably more severe. A cold may only result in minor sniffles, whereas the flu can make you feel so unwell that getting out of bed becomes a challenge.


The flu presents itself rapidly and typically persists for about a week. It is possible to contract the flu at any time of the year, but it is more prevalent during winter. The virus is transmitted through coughing and sneezing from person to person.

Symptoms of Flu

For adults, symptoms of flu include:

  • A sore throat

  • Chills

  • Blocked or a runny nose

  • The temperature of 38°C or may be higher

  • Tiredness

  • Cough

  • Sneezing

  • A headache

  • Achy muscles, usually in legs, arms, back, shoulder, and neck

  • Wheezing while breathing

  • No appetite

    If you experience flu-like symptoms, they typically resolve within a week without treatment. However, it is recommended to consult a doctor in some instances.

Causes of Flu

When someone coughs or sneezes, they release tiny droplets that contain a virus, which is responsible for causing the flu.

It's highly contagious because the germs can survive up to 24 hours on your hands and other surfaces.

How Flu is Diagnosed?

It is typically unnecessary for individuals to seek medical attention or a diagnosis for the flu, as it typically resolves on its own within a week.


It's important to note that certain individuals face a greater risk of experiencing complications from the flu. In such instances, seeking medical treatment may be necessary.


If you are pregnant or over the age of 65 and have flu, it is recommended that you consult a doctor. Additionally, if your symptoms don't improve after a week, or if you have a chronic condition like asthma or diabetes or a weakened immune system, it would be wise to see a doctor.


If you have concerns about your baby or child displaying intense flu symptoms, it is advisable to seek the guidance of a doctor for further assistance.

Flu during Pregnancy

Recovering from the flu is usually a quick process, and medical intervention is typically not necessary. However, during pregnancy, it is crucial to watch for any signs of complications that may arise.


It is advisable to consult a doctor for further guidance if you are expecting and contracting the flu.
