Concept explainers
To answer:
Give two reasons why cold viruses are more prolific in the winter.
Introduction:
The common cold occurs in humans and most of the individuals are infected with the common cold at least twice per year. The rhinoviruses are the most common infection in the upper respiratory system. The common cold infects mostly in the nose, but it also causes infection in sinuses, larynx, and throat. The common symptoms include a sore throat, sneezing, running nose, headache, cough, and fever. The lower respiratory tract has higher temperature, which does not allow the the cold virus to grow. The acidic pH and the warm temperature also inhibit the cold virus growth in the stomach.
