On an average day, you encounter many bacteria, viruses, and fungi, which can make you sick. Infections/ infectious diseases/communicable diseases are caused by pathogens (bacteria, viruses, fungi, and parasites) that can cause diseases.  

Let’s look at the most common Infections that you should be careful about.
