Cold and flu are both related to infections of the respiratory tract so it is very difficult to determine them. Usually cold occur on a gradual basis, whereas flu comes suddenly which you cannot determine that easily since you will feel very normal in the morning but by the afternoon you will feel terrible. The recovery time typically varies from person to person. Generally cold lasts for about a week and for people with strong immunity may get affected only for 2 to 3 days. Flu is a much serious infection which lasts for about 10 to 15 days and the symptoms may lead to fatigue even after that to about a week or so. Cold rarely leads to various complications whereas flu may lead to bronchitis or pneumonia.
- Colds and flu are caused by viruses that affect the respiratory tract leading to infections in the nose and throat.
- The virus just affects the respiratory tract, but symptoms are caused due to the over flooding of the infected region by the white blood cells fled by the immune system to prevent the infection.
- Both these infections are most common during winter season wherein indoor heating literally reduces the humidity present in the air, leading to dryness of the respiratory passage resulting in providing a wonderful breeding place for the virus.
