You can acquire an infectious disease by:

Acquiring an infectious disease can occur through several routes of exposure, and each scenario presented highlights a different method of transmission.

When cleaning up infected blood, doing so with ungloved and chapped hands increases the risk of transmission because broken skin can allow pathogens to enter the body easily.

Injuring yourself with contaminated broken glass also presents a means for infectious agents to enter the bloodstream. Any contact with a sharp object that has come into contact with an infectious substance raises the potential for disease transmission.

Additionally, rubbing your eyes after touching a contaminated surface can lead to infection. The mucous membranes of the eyes are particularly susceptible to pathogens, and touching them after contact with contaminated surfaces allows for direct introduction of infectious agents.

Each of these scenarios illustrates a legitimate pathway through which infectious diseases can spread, confirming that all options represent valid ways to acquire an infection.
