To "become infected with" refers to the process by which an organism or an object acquires a harmful living agent, known as a pathogen, which then begins to multiply and cause a detrimental physiological response. Infection typically occurs when a pathogen, such as a bacteria, virus, fungus, or parasite, invades the body or infects an object in its living environment.
When someone becomes infected with a pathogen, it means that the pathogen has successfully breached the person's immune system defenses and established itself in their body. This often leads to the onset of various symptoms, which can range from mild to severe depending on the type of pathogen and the individual's overall health. Common signs of infection include fever, inflammation, pain, fatigue, and organ dysfunction.
Infection can be spread through various means, such as direct contact with an infected individual or contaminated surfaces, ingestion of contaminated food or water, inhalation of airborne pathogens, or through vectors like mosquitoes or ticks. The transmission of infection is a complex process influenced by factors such as the pathogen's ability to survive outside a host, the duration and strength of contact, and the susceptibility of the recipient.
Prevention and control of infections involve measures such as practicing good hygiene, using protective barriers like masks and gloves, avoiding close contact with infected individuals, maintaining cleanliness of living environments, and receiving vaccinations when available. Prompt diagnosis and appropriate treatment are also essential in managing infections and preventing their spread to others.
