Aches, chills, coughs and fevers - the flu is a disturbing respiratory condition. By detecting and treating symptoms early, you can help prevent the spread of the flu. But what are the symptoms? How does a flu differ from the common cold? And is Panadol (Paracetamol) good for treating symptoms of flu?
The flu is a common seasonal viral infection of the respiratory tract.
The flu is caused by influenza viruses that can spread quickly from one person to another. It is incredibly common, and most people will get the flu at some point in their lives. It can cause serious illness and, in some cases, even death.
The World Health Organization estimates that around three to five million people suffer severe cases of influenza each year. An average 290,000 to 650,000 people die from respiratory issues caused by flu viruses annually1. However, most cases of flu can be treated at home with flu medicine and bed rest.
What are the most common flu symptoms?
It can be difficult to distinguish influenza from the common cold. But the flu usually comes on more suddenly. A fever is often the first sign of the illness.
Influenza usually begins abruptly. The exact symptoms will differ from person to person, but some of the first signs include fever, muscle pain, and a general feeling of discomfort and tiredness.
1. Fever: A fever happens when your body is trying to fight an infection. If your body temperature rises above 38°C or 100°F, you have a fever.
2. Myalgia: Muscle pain (or myalgia) is a common complaint of the flu. Your muscles might ache only in some places or it can feel like your entire body is hurting. There are many other reasons for myalgia, so if this is your only sign, it may not be influenza.
3. Discomfort: Malaise describes a sensation of general weakness and discomfort. You will notice that something is not right and start to feel unwell. It’s often accompanied by fatigue when you have the flu.
Could it be coronovirus?
If you have a high temperature, a new, continous cough or a change in your sense of smell or taste, fatigue, you might be infected with the SARS COVID-19. Please seek medical advice.
Flu symptoms – What to look out for?
Signs and symptoms of seasonal influenza include a fever, cough, body aches and muscle pain, chills, fatigue and a general feeling of discomfort.
Because the flu spreads quickly, detecting symptoms early can encourage people to isolate and prevent further spreading of the virus. You’ll also be able to treat yourself quickly and avoid the illness getting worse.
Common signs of the flu are:

Treatment of seasonal influenza usually includes bed rest, staying warm, and pain medication like Panadol (Paracetamol). If your symptoms persist or get worse, you should see a doctor.
The flu can leave you feeling weak, tired, and unable to focus on your daily tasks. One of the most important things to do when you’re sick is to rest to help your body heal more quickly. From flu tablets to home remedies, which influenza treatment you choose will often depend on the severity of your symptoms.
1. Rest and stay warm: If you notice flu symptoms, you should stay in bed. Sleep has been shown to be restorative and helps the body recover more quickly when you have the flu. It’s important that you stay at home to avoid spreading the virus to other people. Also wash your hands more often and use a tissue when sneezing.
2. Rehydrate: Drink plenty of fluids—water, electrolyte-enhanced drinks or decaf tea/coffee—to replenish lost fluids from diarrhea or vomiting. When your body sweats because of fever, you need to replace the lost water. Avoid caffeinated drinks as these can dehydrate you further.
3. Medicine: Paracetamol (the ingredient in Panadol) or ibuprofen can help lower a fever and make you feel better. It can take around an hour for acetaminophen like Panadol to work and you should feel relief for up to five hours. Because of the wide range of over-the-counter flu medications available, you may wonder is Panadol good for flu? Panadol Cold & Flu + Decongestants caplets is a special formulation that helps you feel better much more quickly than standard flu tablets. It doesn’t just treat the fever and aches, but also a stuffy and runny nose, so you can rest more comfortably.
4. Antiviral drugs: Antiviral tablets are prescription medicines that help reduce the duration of the flu. They’re given to people who are at higher risk of developing complications from influenza to avoid severe health consequences.
What are the complications from the flu?
With proper care and treatment, the flu isn’t serious in most cases and should go away within seven days. Symptoms such as a cough can linger longer.
Some people may also develop more severe symptoms and complications after they get the flu. These can be life-threatening so it’s important you recognize them early on.
Encephalitis: Encephalitis is a very rare complication of the flu. It occurs when the flu virus enters the brain and causes inflammation of the nerve tissue. Signs of this infection include a severe headache, very high fever, nausea and vomiting, and mental confusion. You should call for emergency help if you have hallucinations, double vision, seizures or have difficulty speaking or hearing. Encephalitis is a medical emergency.
What is flu? The causes explained
The viruses that cause the flu are known as influenza type A, influenza type B, and influenza type C. Influenza type A is found in many species including humans, pigs, and birds; while types B and C mostly occur in humans (Although dogs and pigs5 have been known to be infected with type C). The illness passes from person to person through droplets in the air when people sneeze or cough.
Worldwide, annual flu epidemics are estimated to result in about 3 to 5 million cases of severe illness1. Children are more likely to get the flu than adults under the age of 65.4
Although anyone can get the flu, some people are at a higher risk of developing complications. They include:
A Flu Shot for Prevention
While influenza is treatable and, in most people, does not cause severe complications, the best action is prevention. Anyone older than six months and without any life-threatening allergies should get vaccinated, according to the US Centers for Disease Control and Prevention.5
Washing your hands regularly, avoiding touching your nose and mouth, and staying home if you’re not feeling well are other ways you can stop the spread of the flu.
