Frequently Asked Questions

Expert answers from our medical team

How is COVID different from a regular cold or flu?

COVID overlaps heavily with flu and colds — fever, cough, tiredness, body aches, sore throat. Loss of taste or smell is more distinctive to COVID. Only a test can confirm which virus is causing symptoms. The main practical difference: COVID has caused more severe illness in older adults and people with chronic conditions, and can lead to longer-lasting fatigue (long COVID) even after mild infection.

Should I still test if I have COVID-like symptoms?

Yes, especially if you'll be around older adults, pregnant women, or people with weak immunity — knowing lets you avoid spreading. Testing also matters if symptoms are severe enough that antiviral treatment might help (which needs to start early). Home rapid tests are widely available; PCR tests are more accurate. If you test positive, isolate as advised and monitor for worsening symptoms.

What is long COVID and how is it treated?

Long COVID is symptoms lasting more than 12 weeks after infection — commonly fatigue, brain fog, breathlessness, palpitations, and sleep problems. It can happen after even mild initial illness. Treatment is symptomatic and often multi-disciplinary (physiotherapy, pacing, mental health support, sometimes specific medications for individual symptoms). Long COVID clinics exist in major cities. Most people gradually improve over months but a subset have prolonged symptoms.

How do I protect my elderly parents from respiratory infections?

Keep their vaccinations current (annual flu, COVID boosters, pneumococcal). Wash hands before visiting, especially with a cough or cold. Skip in-person visits when you or family members are actively ill. Improve ventilation at home. Get help with chronic conditions well-controlled — diabetes and heart disease worsen respiratory infection outcomes. Have a plan for who takes them to hospital if needed.

When does a respiratory infection need urgent medical attention?

Difficulty breathing at rest, chest pain, confusion, blue lips or fingertips, inability to keep fluids down, oxygen saturation below 94% on a home pulse oximeter, or fever that's very high or lasting more than a few days. In children, look for fast breathing, chest indrawing, or refusal to feed. Don't wait — respiratory illness can worsen fast, especially in older adults.
