As we are experiencing the current flu season, staying informed helps you protect yourself and those around you. With the current flu season in Singapore, learning preventive measures, tests available and symptoms relief is important.
Recognising Flu Symptoms
Flu symptoms often appear suddenly. Common signs include high fever, chills, sore throat, dry cough, muscle and body aches, headache, fatigue, and sometimes nausea. Many people also notice blocked or runny nose, though nasal symptoms are typically less prominent than with a common cold. The abrupt onset and intensity of symptoms can help you distinguish influenza from milder respiratory infections, especially during the period of flu season.
Compared with a cold, which usually starts gradually with sneezing, a mild sore throat, and nasal congestion (often without a significant fever), flu tends to strike quickly and more severely. High temperature, pronounced body aches, and marked tiredness are hallmarks that can make daily tasks difficult. If you are uncertain, consider using home screening options and explore neutral symptom-relief methods to support your comfort while you monitor how you feel. Recognising the behaviour of the flu virus and how influenza presents can help guide next steps.
Seek medical advice if you experience persistent high fever (above 38°C) for more than two days, chest pain, shortness of breath, confusion, signs of dehydration, or if symptoms worsen. People at higher risk—such as older adults, pregnant individuals, and those with chronic illnesses—should consult a healthcare professional early. Early, appropriate care may help shorten recovery time and reduce the risk of spreading to others.
How to Reduce Your Risk: Preventive Measures
Annual vaccination is one of the most effective ways to lower your risk of catching the flu and developing complications. In Singapore, the influenza vaccine is recommended each year, particularly for older adults, young children, pregnant women, and people with chronic health conditions. Appointments are available through participating clinics and pharmacies. Vaccination helps your immune system recognise flu virus and can reduce severity if you do become unwell.
Daily habits also play a crucial role in prevention. Some preventive measures include washing your hands frequently with soap and water for at least 20 seconds, or using an alcohol-based hand sanitiser when handwashing isn’t possible. Avoid touching your face—especially your eyes, nose, and mouth. Practise good respiratory etiquette by covering coughs and sneezes with a tissue or your elbow, and dispose of tissues promptly. Clean frequently touched surfaces, maintain sensible distance in crowded places, and stay at home if you are unwell.
A balanced diet, adequate sleep, and regular activity support normal immune function. Vitamins and supplements such as vitamin C, vitamin D, and zinc contribute to the normal functioning of the immune system, while probiotics support gut health, which is linked to overall immunity. Combining vaccination with everyday hygiene are some practical preventive measures against influenza and the circulating flu virus.
Flu Testing in Singapore
Quick confirmation can help guide care during peak flu season. Testing available options include rapid antigen tests at clinics and healthcare providers; these deliver results within minutes and are useful for timely decision-making. More sensitive molecular (PCR) tests are also offered through medical facilities; they detect influenza A and B with high accuracy and are often recommended for people at higher risk of complications. While clinical testing remains the standard, at-home screening kits for cold and flu-like symptoms are increasingly accessible for preliminary checks and can be part of testing available pathways now.
You can book flu testing through a GP clinic, selected healthcare centres, or via telehealth providers who can advise on the most suitable option. If you prefer to monitor symptoms initially, prepare a home care kit with essentials—such as thermometers, fever reducers, hydration solutions, tissues, throat lozenges, and nasal sprays—to manage discomfort safely while you observe your symptoms and assess for influenza caused by the flu virus.
After testing, a positive result typically means resting, hydrating, and following medical advice, particularly if you are in a higher-risk group. Where possible, isolate to reduce transmission and monitor your temperature regularly. A negative test early in illness may not completely rule out flu; if symptoms persist or worsen, seek clinical evaluation. In all scenarios, maintain good hygiene, wear a mask if you are unwell, and continue with some preventive measures.
Safe and Effective Symptom Relief
Managing symptoms well can help you feel better and reduce disruption to your routine. Over-the-counter options include paracetamol or ibuprofen to relieve fever, headaches, and body aches, and decongestants for nasal blockage. Saline nasal sprays can soothe irritated nasal passages, while throat lozenges and cough syrups may ease a sore throat and troublesome cough.
Pair medicines with simple home measures. Prioritise rest and adequate sleep to support recovery. Steam inhalation or a warm shower can help loosen mucus and ease congestion. A warm salt-water gargle may provide short-term relief for a sore throat, and using a humidifier can help maintain comfortable moisture levels in your home environment, aiding symptoms relief while the flu virus circulates.
Hydration and nutrition are important. Sip water regularly and consider oral rehydration solutions if you have a fever or sweating. Warm fluids such as clear soups and herbal teas can be soothing while helping you maintain fluid intake. Choose balanced, easy-to-digest meals rich in fruits, vegetables, and lean proteins to provide essential nutrients. If your appetite is low, opt for small, frequent meals.
When to See a Healthcare Professional
Recognising red flags and seeking timely care can reduce the risk of complications. Contact a healthcare professional if you have persistent high fever (38°C or above) for more than three days, severe sore throat with difficulty swallowing, chest pain, shortness of breath, wheezing, confusion, signs of dehydration (such as very dark urine or dizziness), or a worsening cough producing green or bloody mucus. Vulnerable groups—including older adults, pregnant individuals, young children, and people with chronic conditions like asthma, diabetes, or heart disease—should seek advice early, even if symptoms are mild.
