Flu

Flu

Although our medicine is very advanced, and we can cure many diseases, we still cannot beat a simple flu. This is because it mutate very fast, and our antibodies and vaccines cannot identify it as a virus, so they cannot destroy it. Interesting fact is that virus change only ‘’its appearance’’ so our defense mechanism cannot detect it like danger.

People make a serious mistake when thinking that flu and common cold are the same disease. The flu is caused by different viruses and it has much longer and severe symptoms. Its full name is Influenza. Flu viruses are active during the whole year, but during the winter, this disease is known as season flu. The symptoms of flu are: headache, high temperature, tiredness, sore throat and general aches. You can take paracetamol or ibuprofen, to lower down your temperature. But all you can do is to stay home, in bed, and drink a lot of fluid. After a few days you will feel better. If you are older than 65 or you are pregnant, you should visit a doctor after the first symptoms appear, because it can get complicated and cause more severe health problems! In the UK, 600 persons per year die, because complications caused by flu! Antibiotics are useless in case of a flu, because it is caused by a virus, not by bacteria.

The flu virus is spread in fluid droplets sneezed or coughed into the air. When a person inhales that virus, it will start to multiply in your body. The cells in your throat will be affected first. But, our immune system is very effective, and after a few days, it will destroy the virus.
