It takes two to three days for a person to start experiencing cold symptoms after coming in contact with an infected person, according to MedlinePlus. Children are at a higher risk of catching cold since they tend to have close contact with many people.
The early symptoms that a person experiences include sneezing, nasal congestion, runny nose and scratchy throat. Adults may not have a fever, but children will experience fever. The symptoms also depend on the virus that caused the cold. In some people, the cold may get better after a few days. Having enough rest and taking fluids can help with the condition. Antibiotics should not be used in the treatment of colds.
