Good hygiene plays a critical role in preventing bacterial infections by limiting exposure and reducing microbial growth. Regular handwashing, clean wound care, safe food handling, and environmental sanitation interrupt transmission pathways. When hygiene lapses occur, bacteria can enter the body through skin breaks, respiratory droplets, or contaminated surfaces, increasing infection risk. In clinical practice, prevention is paired with treatment when infections develop. Antibiotics, including cephalexin capsules, may be prescribed to manage susceptible bacterial conditions under professional guidance. However, medication works best alongside consistent hygiene habits, which lower recurrence, protect communities, and support antimicrobial stewardship by reducing unnecessary antibiotic use overall.
