Flu and pneumonia are diseases that are often confused with each other, with their symptom similarities and the fact that flu, one of the upper respiratory tract infections turns into pneumonia as a result of not being treated properly. This week, we will clarify the relationship between flu and pneumonia and talk about what should be done to prevent pneumonia. Lower respiratory tract infections, including pneumonia, rank 4th among diseases that cause death worldwide. We believe that it is very important to have awareness on this issue. 
What is Pneumonia?
Pneumonia is known as a lung tissue infection. Pneumococcal bacteria are the most common bacteria that cause pneumonia. Some chemicals that irritate the lung and exposure to radiation are other reasons that cause pneumonia. Pneumonia is an important life-threatening disease in people over the age of 65 and people with chronic diseases.
Difference Between Pneumonia and Flu
Cough, runny nose, or fever are important symptoms that cause the confusion between flu and pneumonia. One of the most decisive consequences is pneumonia is rare in healthy adults without medical problems.
While pneumonia has more respiratory symptoms, the flu includes headache, muscle pain, and fatigue along with the respiratory symptoms.
The flu comes on suddenly. Pneumonia takes longer to develop, and a complication from the flu can cause pneumonia.
While the flu is caused by a viral infection, pneumonia can be caused by a bacterial infection or a viral infection.
Since flu types change every year, flu vaccination should be repeated every year to be protected against the newest type. The pneumococcal vaccine should be repeated 5 years later to prevent pneumonia.
Many doctors say flu is more contagious than pneumonia between healthy individuals. 
Ways to Prevent Pneumonia
Microbe entering the body may not cause pneumonia in every person. The same microbe can cause flu in someone with high immunity, and pneumonia in someone with low immunity.
It is possible to prevent pneumonia by keeping the body resistance high. Healthy eating, consuming plenty of water, paying attention to hygiene and regular sleep strengthen your immunity and protect against pneumonia and many diseases.
Pneumococcal bacteria are the most common bacteria that cause pneumonia.
There is a pneumococcal vaccine developed against pneumococcal bacteria. Although this vaccine does not provide 100% protection, it provides protection to people in high risk groups.
Flu is known to cause or facilitate pneumonia, so protecting from the crowd and wearing masks during flu epidemics provides protection.
