Why we have no cure for common cold yet?
Common cold is a viral infectious disease of the upper respiratory tract that mainly affects the nose. With other health problems or already weak immune system, one may develop pneumonia also.
Over 200 virus strains are implicated in causing the common cold, with rhinoviruses being the most common. These viruses stick to the cells at the back of your throat. They quickly reproduce from the cells to spread to neighboring cells in the rest of the tract.
And while we can treat the symptoms of cold by isolating the virus like other diseases, we cannot cure it, because of their different types and rapid mutation property of each of those types. Thus, in the time it takes to develop a vaccine, it will no longer be useful to us.
Symptom difference with flu and Pneumonia?
Apart from acute viral respiratory illness being a common symptom, the basic difference between below diseases are:
Common cold: Less severe symptoms, runny nose, sore throat
Influenza (flu): severe symptoms, (less likely to have a runny nose), fever, chills, fatigue, muscle aches
Pneumonia: severe symptoms, sharp chest pain with inhalation, excessive sweating, increased breathing and heart rate and light blueness around the mouth and lips.
