As the seasons change it’s not uncommon to find yourself fighting a case of sniffles, covering a new cough, or rubbing itchy eyes…but what causes this and what are theses symptoms different depending on the time of year?

Summer colds and winter colds share similarities, but there are notable differences:

  1. Causative Viruses:
    • Summer Colds: Often caused by enteroviruses or adenoviruses, which thrive in the heat.
    • Winter Colds: Typically caused by rhinoviruses, which are less heat tolerant.
  2. Spread and Contagion:
    • Both types can spread through infectious droplets (sneezing, coughing).
    • Summer colds occur less frequently due to fewer indoor gatherings during warm weather.
  3. Symptoms:
    • Winter Colds: Sneezing, runny nose, congestion, itchy throat, and fever.
    • Summer Colds: May include coughing, sweating, and fever.
    • Allergies: Last longer and lack fever.
  4. Differentiating Allergies:
    • Colds: Symptoms appear sequentially.
    • Allergies: Symptoms emerge simultaneously.
    • Nasal Discharge: Thicker and colored for colds, translucent for allergies.

How to Fight a Cold:

Remember, even in the heat, the rhinovirus can still spread, so take care and rest up!
