where does the influenza virus settle in your body
Influenza Influenza viruses bind through hemagglutinin onto sialic acid sugars on the surfaces of epithelial cells, typically in the nose, throat, and lungs of mammals, and intestines of birds (Stage 1 in infection figure).[67] After the hemagglutinin is cleaved by a protease, the cell imports the virus by endocytosis.[68]
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]
