An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. An infectious disease is an illness resulting from an infection, and some infectious diseases are also communicable (transmissible).
Infections can be caused by a wide range of pathogens, most prominently bacteria and viruses. Hosts can fight infections using their immune systems. Mammalian hosts react to infections with an innate response, often involving inflammation, followed by an adaptive response.
Treatment for infections depends on the type of pathogen involved. Common medications include:
Antibiotics for bacterial infections.
Antivirals for viral infections.
Antifungals for fungal infections.
Antiprotozoals for protozoan infections.
Antihelminthics for infections caused by parasitic worms.
Infectious diseases remain a significant global health concern; communicable, maternal, neonatal, and nutritional diseases together accounted for an estimated 18.6% of global deaths in 2017. The branch of medicine that focuses on infections is referred to as infectious diseases.
How this connects to Paediatrics
Infectious-disease biology depends on organism properties, entry route, replication, tissue tropism and host response. Infection must be distinguished from colonization or contamination. Laboratory test timing, specimen quality and local epidemiology affect interpretation; antimicrobial choice requires current susceptibility and professional guidance.

What the underlying subject studies
Paediatrics studies health and disease across rapidly changing developmental stages. Anatomy, normal vital signs, metabolism, immune function and expected behavior vary with age, so adult assumptions cannot simply be transferred to children.
How mechanisms and evidence connect
Assess growth longitudinally and development across motor, language, cognitive and social domains. Environmental context, feeding, caregivers, immunization and congenital factors may influence health.
How to develop a sound explanation
When studying a pediatric disorder, begin with the age group, developmental context, likely mechanism and assessment principles. Emergency skills and medication dosing require dedicated, supervised pediatric training.
