Viruses and bacteria can significantly impact the human body by causing a range of illnesses and infections. Bacteria, some of which are beneficial to our health, can lead to diseases such as strep throat or urinary tract infections when pathogenic strains invade. Viruses, on the other hand, invade host cells to replicate, often resulting in illnesses like the common cold or influenza. The body's immune response to these pathogens is essential for recovery, but it can also contribute to symptoms like inflammation and fever.
