Transmission of respiratory infections can also occur by touching the nose or mouth by hand or other object exposed to the virus. What are the causes of the upper respiratory infection? URTI is usually caused by the direct invasion of the inner lining (mucosa or membrane) of the upper part by the virus or guilty bacteria. For pathogens (virus and bacteria) to invade the mucous membrane of the upper respiratory tract, they have to fight through various physical and immunological barriers. Hair in the lining of the nose acts as a physical barrier and can potentially catch invading organisms. In addition, the wet mucus inside the nasal can thicken the viruses and bacteria that enter the upper respiratory tract. There are also small structures similar to hair (cilia) that border the trachea that constantly moves any foreign invader to the pharynx to be eventually swallowed in the digestive tract and stomach. In addition to these intense physical barriers in the upper respiratory tract, the immune system also makes its part to fight the invasion of pathogens or microbes entering the upper airway. and located in the upper respiratory tract are part of the immune system that helps fight infections. Through the actions of specialized cells, antibodies and chemicals within them, invasive microbes are wrapped within them and eventually destroyed. Despite these defense processes, invasive viruses and bacteria adapt various mechanisms to resist destruction. Sometimes they can produce toxins to harm the body's defense system or change its external structural form or proteins to conceal from being recognized by inmunitary systems (change of antigenicity). Some bacteria can produce adhesion factors that allow them to cling to the mucous membrane and hinder their destruction. It is also important to note that different pathogens have a variable capacity to overcome the body's defense system and cause infections. In addition, different organisms require a time of variable appearance from the moment they enter the body until symptoms occur (incubation time). Some of the common pathogens for upper respiratory infection and their respective incubation times are as follows: SLIDESHOW What are the symptoms of upper respiratory infection?Symptoms Generally, the symptoms of upper respiratory infection result from the toxins released by pathogens, as well as the inflammatory response mounted by the immune system to fight infection.
