where does the cold virus live in the body
Common cold The common cold, also known simply as a cold, is a viral infectious disease of the upper respiratory tract that primarily affects the nose.[7] The throat, sinuses, and larynx may also be affected.[5] Signs and symptoms may begin less than two days following exposure.[5] They include coughing, sore throat, runny nose, sneezing, headache, and fever.[2][3] People usually recover in seven to ten days.[2] Some symptoms may last up to three weeks.[6] In those with other health problems, pneumonia may occasionally develop.[2]
Viral entry Prior to entry, a virus must attach to a host cell. Attachment is achieved when specific proteins on the viral capsid or viral envelope bind to specific proteins called to receptor proteins receptors on the cell membrane of the target cell. A virus must now enter the cell, which is covered by a phospholipid bilayer, a cell's natural barrier to the outside world. The process by which this barrier is breached depends upon the virus. Types of entry are:
