What is Flu?
Flu is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe illness, and at times can lead to death. Flu is spread mainly by droplets made when people with flu cough, sneeze or talk. It can also be spread by touching surfaces or objects contaminated with the virus and then touching your mouth, nose, or eyes.
Causes of Flu
There are many causes of flu. The most common cause is the virus. Other causes include bacteria, environmental factors, and genetics.
The virus is the most common cause of flu. The virus is a tiny organism that can spread through the air, through contact with saliva or mucus, or through contact with objects that have been contaminated with the virus. The virus can cause a range of symptoms, from a mild cold to a serious illness.
Bacteria can also cause flu. There are several types of bacteria that can cause flu, including Streptococcus, Staphylococcus, and Mycoplasma. These bacteria can spread through the air, through contact with saliva or mucus, or through contact with objects that have been contaminated with the bacteria. These bacteria can cause a range of symptoms, from a mild cold to a serious illness.
Environmental factors can also cause flu. These factors include smoke, pollution, and changes in the weather. These factors can cause the virus or the bacteria to spread more easily and can increase the risk of developing flu.
Genetics can also play a role in the development of flu. Some people may be more likely to develop flu because they have a genetic predisposition to the virus or the bacteria.
