Viruses and Bacteria


Viruses and bacteria, invisible to the naked eye, wield immense influence. Viruses are tiny parasites, hijacking host cells to replicate and spread diseases like the flu and COVID-19. Bacteria, diverse microorganisms, play roles from digestion to nitrogen fixation. Some are harmful, causing infections, while others are beneficial, aiding in food production. Antibiotics battle bacterial infections, but misuse leads to resistance. Viruses have no cure; vaccines prevent their havoc. The ongoing battle against these microscopic foes highlights the delicate balance between their potential for harm and their crucial roles in shaping ecosystems and human health. Understanding them is vital for a healthier world.
