Thinking like a parasite

Parasites are organisms that rely on hosts for food and shelter. They can enter hosts through water, food, or direct contact, causing illnesses. Parasites vary in size and type, including single-celled organisms and worms. They impact host health by secreting toxins and fighting the immune system. Parasites have complex lifecycles, often involving multiple hosts. They absorb nutrients like vitamins and amino acids from their hosts, leading to health issues. Parasites reproduce rapidly, ensuring their survival and spread.
