The common cold is known by other names including acute coryza, nasopharyngitis, cold, head cold or rhinopharyngitis. This condition mainly affects the upper respiratory tract causing sneezing, runny nose and nasal congestion.
It is known as the common cold for a reason since it affects billions of people each year. People experience common cold more times than other conditions. Children tend to be the most affected by the common cold than adults. Its virus is usually very contagious during the first 2 or 3 days of a cold, so a person can get it when an affected person sneezes or coughs, as stated by MedlinePlus.
