INSIGHT

Why No Common Cold Cure?

  • There are over 160 different cold viruses, called rhinoviruses, making a single cure impossible.
  • Each virus has a unique shape, preventing antibodies from one cold from protecting against another.
INSIGHT

Cold Transmission

  • Colds spread through breathing, sneezing, or touching contaminated surfaces, not cold temperatures.
  • The virus can survive on surfaces for up to 24 hours, highlighting the importance of hand hygiene.
ADVICE

Contagion Period

  • If you have cold symptoms, stay home and avoid contact with others.
  • The belief that you're not contagious after a few days while still symptomatic is a myth.
