What is a patogene?

A pathogen is a microorganism that causes disease. This can include bacteria, viruses, fungi, and parasites. Pathogens can spread through the air, water, food, or contact with an infected person or animal. Some common pathogens include:

* Bacteria: such as Salmonella, E. coli, and Streptococcus pneumoniae

* Viruses: such as influenza, measles, and HIV

* Fungi: such as Candida, Aspergillus, and Cryptococcus

* Parasites: such as malaria, hookworm, and tapeworm

Pathogens can cause a wide range of diseases, from mild to severe. Some pathogens can even be fatal. The severity of a disease depends on the type of pathogen, the person's immune system, and other factors.

There are a number of things that can be done to prevent the spread of pathogens, including:

* Washing your hands frequently with soap and water

* Covering your mouth and nose when you cough or sneeze

* Avoiding contact with people who are sick

* Getting vaccinated against preventable diseases

* Practicing safe sex

* Eating only properly cooked food

* Drinking only clean water

By following these tips, you can help to reduce your risk of getting sick from a pathogen.
