What is one method to prevent horizontal transmission of infections?

Using proper hand hygiene is a crucial method for preventing horizontal transmission of infections. This type of transmission occurs when infections are spread from one person to another, often through direct or indirect contact. Effective hand hygiene, which includes regular handwashing with soap and water or the use of alcohol-based hand sanitizers, helps eliminate pathogens that can be easily transferred during interactions. By cleaning hands thoroughly, individuals significantly reduce the likelihood of passing on harmful microorganisms that can cause illness, thereby breaking the chain of infection.

In contrast, while avoiding contact with others may reduce transmission, it's often impractical in many social and professional settings. Improving ventilation systems can help reduce airborne pathogens but does not directly address hand-to-hand or surface-to-hand transmission. Limiting vaccinations is counterproductive, as vaccinations are essential for preventing the spread of infections, particularly amongst populations that may be at higher risk.
