Common Cold
What is it?
The common cold is an infection of the nose and throat (upper respiratory tract). In most cases, the common cold is harmless, despite feeling unwell. A variety of viruses can cause colds. The most common cause is the rhinovirus.

Transmission
Sneezing, coughing, or speaking can release tiny droplets containing infectious agents. Inhalation of air droplets can cause the common cold virus to be transmitted. Sometimes the droplets land on a surface contaminating it, touching the surface while the virus is active and then touching your face can transmit the virus.
Diagnosis
The Doctor can diagnose most common colds with an examination and checking symptoms. The Doctor may recommend tests if they suspect other conditions. To rule out other infections, the Doctor may request a rapid antigen test (RAT), a polymerase chain reaction (PCR) swab, a chest x-ray, and a rapid influenza diagnostic test (RIDT).
