"Comparing Viral and Bacterial Infections:"
Comparing Viral and Bacterial Infections: Bacterial and Viral Infections show some similarities: • They can cause illness, and even death • Are highly infectious- meaning they can be passed from person to person Bacterial and Viral Infections Are Different • Bacterial Infections are caused by living organisms (bacteria)- single-celled prokaryotes • Viral Infections are caused by things that usually are not considered alive. Examples of Bacterial Infections: • The Common Cold • Strep Throat • Mononucleosis • Ear infections, etc Examples Of Viral Infections: • Eth Flu • HIV (AIDS virus) • Herpes • Hepatitis • Chicken Pox • Measles, Mumps We treat Bacterial Infections with: • Rest • Antibiotics- because the cells that cause us to get sick are alive, we can kill them (by poisoning them with antibiotics) Viral Infections • We cannot use antibiotics on these because you cannot kill something that isn’t alive. • We treat the symptoms with medicines that help with fever, aches, congestion, etc. We can prevent Viral Infections by using Vaccines • Vaccines work by introducing a dead or weakened virus into your body, so your immune system can generate antibodies that will destroy the real virus. We can prevent Viral Infections by using Vaccines • When the “real” virus infects your body, your immune system quickly reacts by producing antibodies that destroy the virus before you get sick.
