Chapter 12 tackles infectious diseases. We have pathogens to thank for all of the diseases that exist. Diseases can be endemic (the common cold), an epidemic (the plague), or a pandemic (the flu). It is important to understand how our immune system operates in relation to the fight against pathogens, and how we can aid our immune system in that fight. Avoiding germy situations, or disinfecting properly when coming in contact with germs, as well as mindfulness are great ways to help your body and avoid disease.
Viruses are the smallest known pathogens, and cause viral infections such as mono, hepatitis, herpes, mumps, measles, and rubella. Other pathogens include bacteria, fungi, protozoans, parasitic worms, and prions.
Trying to prevent the spread of pathogens has consequently caused antibiotic resistance for humans. Some of these issues include overabundance of antibiotics in foods, unnecessary prescriptions, and the misuse/overuse of cleaning products. By understanding these issues, we can hopefully avoid them!
The chapter goes on to discuss sexually transmitted diseases and infections, which we have already addressed in previous chapters. Basically they are spread through infected body fluids, which is why protection and testing should be a common practice in our lives.
With cold and flu season approaching, stay safe out there and remember what you have learned from this chapter about spreading and preventing infectious diseases!
