👉 Millions of bacteria, viruses, fungi, and parasites can enter the body through various routes, such as the air, food, water, or direct contact with infected individuals. Once inside, these pathogens can cause infections if they evade the body's immune defenses or establish a foothold in vulnerable tissues. Millions of these microorganisms can multiply rapidly, leading to conditions ranging from mild infections like strep throat to severe illnesses such as pneumonia, sepsis, or meningitis. The severity of an infection depends on factors like the pathogen's virulence, the host's immune status, and the site of infection. Effective prevention and treatment strategies, including antibiotics, antivirals, antifungals, and hygiene practices, are crucial in managing and reducing the impact of infections.
