What are the different causes of respiratory infections?

Viruses, bacteria and fungi are among the common causes of respiratory infections, while viruses lead the way as the most common. Bacteria are usually other most common and fungi generally cause respiratory infections less frequently. Sometimes the initial cause of respiratory infection irritation of the respiratory tract, which leaves a person vulnerable to infection. Most people sometimes suffer from minor respiratory infections and serious infections can rarely develop. An individual with a depressive immune system is more likely to develop a serious and hard -to -healing infection than an average person, but anyone can become a victim of a serious respiratory disease.

In most places, the viruses are highest in the list of causes of respiratory infection. This is due to the fact that viruses that cause this type of infection are usually highly contagious and spread by droplets in the air and contact. For example, a person could capture virus -breathing in the same air space in which the infected person has just cooked or sneezed. One can alsocatch the virus by kissing an infected person or touching the surface that has a virus on it and then touches his eyes, nose or mouth.

Bacteria are also common causes of respiratory infections. Sometimes these infections are contractual in almost the same way as viruses, but they can also evolve in other ways. For example, if a person inhales a substance that contains bacteria causing infection, he may illustrate. A person can also develop a viral infection that complicates bacterial infection - it is a special problem for people who have weakened immune systems. For example, a person can develop the flu, but instead of getting better in a week, it progresses into bacterial lung infection.

The common causes of respiratory infection belonged to the fungus, albeit rarely. Sometimes a person inhas mold spores and as a result is ill, but it is not always easy to identify the cause of the infection in this case. In other casesECH can start fungal infection in another part of the body and then spread to infect the respiratory system. Mushrooms can infect anyone, but those with weakened immune systems may prove to be the most vulnerable. For example, a person who has an immune system, such as an immune deficiency syndrome (AIDS), may be more likely to develop fungal respiratory infections and have difficulty fighting than a person with a normal immune system.
