👉 Infection is a biological process where pathogens, such as bacteria, viruses, fungi, or parasites, invade and multiply within a host organism, leading to disease. This interaction can disrupt normal cellular functions and trigger immune responses, which may either eliminate the pathogen or cause harm to the host. Understanding infection is crucial in medicine for diagnosing diseases, developing treatments, and preventing the spread of illnesses. Effective infection control measures, such as vaccines, antibiotics, and hygiene practices, are essential to mitigate the impact of infections on public health.
