Risk Factor: Age
One of the major risk factors for contracting the common cold is age. Children who are younger than six years old are particularly vulnerable to this viral infection. The reason behind this susceptibility lies in their less-developed immune systems. Additionally, young children are likely to spend a significant amount of time in day care centers or schools where they come into contact with other children, increasing their exposure to viruses.
Children at this age are often less conscious of the spread of viruses and may not cover their mouths while coughing or sneezing. Furthermore, they tend to touch various objects and toys, inadvertently contaminating them with the cold virus.
Risk Factor: Weakened Immune System
A weakened immune system can be attributed to various factors and conditions. Certain individuals are born with primary immune deficiency diseases, while others may experience a weakened immune system due to factors such as burns, diabetes, or undergoing chemotherapy. When the immune system is not strong enough to combat viruses, the body becomes susceptible to infections.
