Final answer:
Influenza and measles are two diseases that require airborne precautions due to their spread through inhalation of infected respiratory aerosols.
Step-by-step explanation:
Two examples of diseases that require airborne precautions are influenza (also known as the flu) and measles. These diseases are transmitted when pathogens contained in droplets are expelled into the air through actions such as coughing, sneezing, or talking. Influenza is a respiratory illness that can lead to significant morbidity and mortality, especially during epidemic outbreaks. Measles, once controlled through widespread vaccination, has seen resurgences in areas with lowered vaccination rates. Both of these diseases can be spread through the inhalation of respiratory aerosols from an infected person, making it essential that airborne precautions, such as wearing masks and ensuring proper ventilation, are adhered to in order to prevent their spread.
