First we arrived at the first station!

Well then, I will explain. I am calling it "viruses" as a whole by collecting viruses, bacteria and fungi, which cause diseases. Viruses and bacteria ・ fungi are "pathogens", respectively, but their structure and structure are different.

What is fungus? I have never heard of it.

Fungus says things about mold.

Transferring from [pathogen present] to [pathogen free] is said to be "infection" and this method of migration is called "infection route". Infection routes include contact infection, droplet infection, air infection, oral infection, and mother-to-child infection. Let's take a closer look at each infection route.

First of all, it is about contact infection. Contact infection is an infection route mainly infected from the mouth by touching hands, fingers, vomit or the like. Measles with symptoms like colds (measles), noroviruses causing vomiting and diarrhea, etc. are infected by this "contact infection" route.

Next, it is about droplet infection. Droplet infection is a route that infects by coughing or sneezing containing bacterial particles of 0.005 mm or larger. Bacteria land on the ground in about 1 m. Influenza, common cold, pain under the ear, mumps accompanied by fever etc. are infected by this "droplet infection" route.

Next, it is about air infection. Airborne infection is a pathway in which particles smaller than 0.005 mm are infected in the air and are infected. Tuberculosis etc infects by this "air infection" route.

What is different between air infection and droplet infection?

You noticed a nice place.

The difference between droplet infection and air infection is that the droplet infected bacteria contain moisture and are heavy, so it will land on the ground about 1 meter. On the other hand, airborne bacteria are light, so they continue to drift in the air.

Next, it is about oral infection. Oral infection refers to the route of infection when mouthing foods, drinks and dishes with pathogens. Viral gastroenteritis (also infectious gastroenteritis) that food poisoning caused by mouthing food and drinks which are dirty by V. cholerae, nausea etc. are infected by this "oral infection" route.

Next, I am about mother-to-child infection. Mother - to - child infection is the pathway where pathogens infect mothers to their babies. Illness such as toxoplasmosis and type B pneumonia infects with this "mother-to-child transmission" route.

Did you know about each infection route?

Yes!

Yes!!
