What is the primary method for protecting oneself against biological agents?

Personal hygiene is the primary method for protecting oneself against biological agents because it directly helps minimize the risk of exposure and infection. Practicing good personal hygiene, such as regular handwashing, using sanitizers, and maintaining cleanliness, removes potential pathogens from surfaces and prevents their spread.

While wearing protective armor can provide a layer of physical defense against certain contaminants, it is typically less practical for everyday scenarios involving biological agents. Staying indoors may reduce exposure, but it is not a foolproof method as biological agents can be present in various environments. Vaccination is an important preventive measure against specific diseases caused by biological agents, but it does not provide comprehensive protection against all potential threats. Thus, personal hygiene stands out as a constant and accessible practice that effectively helps individuals reduce their risk of encountering biological agents in day-to-day life.
