Question

the common cold causes fever, congestion, headaches and runny nose. while these common symptoms can treated by over - the - counter drugs, the common cold cannot be cured with antibiotics. are colds caused by bacteria or viruses?

Explanation:

Antibiotics target bacteria by interfering with their cell - wall synthesis, protein synthesis, etc. Since the common cold is not cured by antibiotics, it is not caused by bacteria. Viruses have different structures and replication mechanisms than bacteria, and antiviral medications (not antibiotics) are used for viral infections (though there are limited over - the - counter effective antiviral for common cold compared to symptom - relieving drugs).

Viruses
