’Flu symptoms usually come on quite quickly, and unlike a cold, can be quite severe early on, usually with fever & body aches.

The worst symptoms can last for a week or more and may be severe enough to keep you in bed for a number of days. The symptoms can linger on after the worst of the infection has passed.

If you have flu symptoms and have difficulty with breathing, sudden dizziness, severe or persistent vomiting, you should get medical care right away.

Causes

’Flu is highly contagious and can be contracted from being in contact with someone who has the virus, as it is easily spread through their coughs & sneezes.

You can catch it from touching anything that someone with an active ’flu virus has recently touched (such as a keyboard, door handle, or cup handle), and of course from kissing or close physical contact with an infected person.

FAQs

How is flu different from a common cold?

Flu symptoms usually come on suddenly and are more severe than a cold. Fever, muscle aches, and extreme tiredness are common with flu but rare with a cold. Colds are generally milder and mainly affect the nose and throat.

How does flu spread?

The flu spreads mainly through droplets from coughs and sneezes. You can also get infected by touching surfaces contaminated with the virus and then touching your mouth, nose, or eyes.

Who is at higher risk for severe flu?

People at higher risk include young children, adults over 65, pregnant women, and individuals with chronic conditions such as asthma, diabetes, or heart disease.

When should I see a doctor for flu symptoms?

See a doctor if you experience high fever, difficulty breathing, chest pain, persistent vomiting, confusion, or if your symptoms worsen instead of improving after a few days. High-risk individuals should seek medical advice early.

How can I protect my family and others if I have the flu?

Stay home until symptoms improve, cover your mouth and nose when coughing or sneezing, wash hands frequently, and avoid close contact with vulnerable individuals like the elderly or those with chronic illnesses.
