Are there bacteria in spit

There are bacteria in saliva, and there is normal flora in the human mouth. As long as there is no imbalance in the bacterial flora, it means that the oral cavity is relatively healthy. If there is an imbalance in the bacterial flora, some diseases may occur. In addition, for some patients, droplet-transmitted diseases are also relatively common, and these diseases are also relatively numerous, such as common tuberculosis, more common viral colds, etc.

Which diseases are spread through droplets?

In life, many people will fall ill inexplicably during the peak period of epidemics. In fact, some diseases can be transmitted through droplets in the air, especially in crowded places such as shopping malls, squares, and schools. Students in school must learn more about campus infectious diseases so that they can take timely preventive measures during the peak period of the disease. Which diseases in schools are transmitted through droplets? This is also a question that many students and parents want to know.

Droplet transmission is the main route of transmission for many infectious agents. Droplets are dispersed by air disturbances and float in the wind for a short time and distance. They adhere to the next host when they breathe, open their mouths, or accidentally touch the surface of their eyes, causing the new host to be infected. Since the droplets are small in quality and quantity and cannot carry heavier pathogens, parasitic infections are rarely transmitted to other individuals through this route.

Respiratory diseases are generally transmitted through air and droplets, such as tuberculosis, SARS, mumps, influenza, common cold, measles, etc. It is recommended to increase physical exercise, strengthen physical fitness, and improve immunity so as to avoid illness. For many students, they should also pay attention to personal hygiene. Once someone is suffering from an infectious disease, they must be isolated in time so that the body can stay healthy.
