Understanding Influenza

Influenza, commonly called the flu, is a contagious viral infection that affects the nose, throat and lungs. Symptoms usually begin suddenly and range from mild to severe. Most people recover within a week, but flu can lead to serious complications in young children, older adults, pregnant individuals and those with long‑term medical conditions.

Flu spreads easily in the winter months when people spend more time indoors. Inspire Pharmacy helps provide guidance on effective treatments and prevention options to reduce symptoms and promote faster recovery.

• Sudden fever
• Muscle aches
• Fatigue and weakness
• Dry persistent cough
• Sore throat

Causes of Influenza

Influenza is caused by flu viruses that spread through respiratory droplets when an infected person coughs, sneezes or talks. The virus can also spread when someone touches a contaminated surface and then touches their nose, mouth or eyes.

Cold temperatures and poor ventilation increase transmission, which is why flu season peaks during winter.

• Respiratory droplets
• Close contact with infected individuals
• Touching contaminated surfaces
• Weakened immune system
• Cold weather environments

Symptoms of Influenza

Flu symptoms typically come on quickly, unlike the common cold. They often include fever, body aches, chills and headaches. Some individuals may experience vomiting or diarrhoea, especially children.

Most symptoms improve within 5–7 days, but fatigue may continue for weeks.

• High temperature
• Headache
• Body aches
• Chills
• Nasal congestion

Treatment Options for Influenza

Most cases of flu can be managed at home with rest, hydration and over‑the‑counter medicines for pain and fever. Steam inhalation and warm fluids may help relieve congestion. Antiviral medication may be recommended for people at higher risk of complications or for severe cases.

These antivirals work best when taken within the first 48 hours of symptoms.

• Rest and hydration
• Paracetamol or ibuprofen
• Antiviral medicines (when appropriate)
• Cough suppressants
• Warm steam inhalation

Prevention & Long‑Term Management

The annual flu vaccine is the most effective way to prevent influenza. Good hygiene practices, such as regular hand‑washing, covering coughs and keeping frequently touched surfaces clean, help reduce the spread.

Boosting immunity through healthy lifestyle habits also provides long‑term defence.

• Flu vaccination
• Frequent hand‑washing
• Avoiding close contact with sick people
• Cleaning shared surfaces
• Healthy diet and sleep routine

Seek urgent medical help if you experience difficulty breathing, chest pain, severe dehydration, confusion, persistent high fever or symptoms lasting longer than a week.

High‑risk individuals, including pregnant people and those with chronic illnesses, should seek advice as soon as symptoms begin.
