Infection prevention refers to practices aimed at reducing the risk of spreading infections, particularly in healthcare settings. This includes proper hand hygiene, using personal protective equipment (PPE), and ensuring that surfaces and medical instruments are clean and disinfected. By following these guidelines, healthcare workers can protect themselves and their patients from harmful pathogens. Another key aspect of infection prevention is vaccination. Vaccines help the body build immunity against specific diseases, reducing the likelihood of outbreaks. Public health campaigns often promote vaccination to protect communities, especially vulnerable populations like the elderly and those with weakened immune systems.
