Flu

Flu is the short term for influenza. When we sneeze or cough, then we can spread this viral infection if we are affected from it. When we have this kind of infection, then we feel uncomfortable. This infection will get better in a period of one week. In every part of the year we can be affected with flu. But this infection is most common in the winter. This infection is known as seasonal flu. But there is difference between flu and common cold. They are not the same condition. When you have flu, then this kind of infection is not caused by the same group of viruses which are causing the common cold. When you have flu, then they can start suddenly. Also they can last longer than the symptoms of the common cold and they are more severe.

  1. Flu symptoms: You feel unwell which means that you cannot do the everyday activities. You have aching muscles or fever. The symptoms of the flu come in very quick way.
  2. Cold symptoms: The symptoms of this condition are coming gradually. In the most cases they are affecting the throat and nose. The symptoms of this condition are mild symptoms. This means that you are not all day long in your bed and you can do the everyday activities such as go to work, school, college etc.

Complications of flu: People who are in their older ages, people who have weak immune system, people who take medications in long period and pregnant women are having the biggest chances to get complications from flu. If you are in the mentioned groups, then you must take your annual flu vaccination. Also you must visit your doctor as soon as possible if you have the mentioned symptoms of flu.

People with chronic obstructive pulmonary disease and asthma if they get flu, then they can notice that they symptoms of their disease are more severe than before. This disease also can affect diabetic people. It can cause them hyperglycaemia which means that they will have high blood sugar levels. People who suffer from diabetes type 1 and who get flu this condition can worsen their disease into diabetic ketoacidosis which is very serious and dangerous disease caused by lack of insulin in their bodies.
