- Peak Illness: Symptoms intensify, including persistent cough, sore throat, and nasal congestion.
- Recovery Phase: Fever subsides, but fatigue and cough may linger.

Flu Virus Types
There are several types of flu viruses, but most infections in humans come from Influenza A and Influenza B. These viruses constantly change, which is why seasonal flu vaccines are updated yearly.
Common flu virus types include:
- Influenza A – the most common type, known to cause outbreaks and epidemics.
- Influenza B – typically less severe but still contagious; it contributes to seasonal flu.
- Influenza C – usually causes mild respiratory symptoms and doesn’t spread easily.
- Influenza D – mainly affects animals, not people.
Our walk-in clinic offers care for both Influenza A and B infections. If you’re unsure what’s causing your symptoms, our healthcare professionals can run flu testing to help confirm the type and start the right flu virus treatment for you.
