Q6.7. During many epidemics, health-care professionals emphasize the importance of

Serga [27]

During many epidemics, healthcare professionals emphasize the importance of community mitigation strategies, such as wearing masks, frequent hand-washing, and social distancing because these strategies help reduce transmission even when drug-based treatments and vaccines are unavailable.

It is of vital importance in cases of epidemics to implement strategies such as:

Hand-washing
Wearing masks
Social distancing

in order to better protect our communities and ourselves.

Frequent hand-washing serves to eliminate the presence of a pathogen from the surface of your hands, reducing the risks that it will find entry into your organism or land on a surface with which others will come into contact. Should you or someone else contract the pathogen anyways, wearing a mask can help to reduce or deny the possibility of transmitting the disease.

Finally, should both previous measures fail, meaning that the virus or pathogen has infected an individual and penetrated the masks, social distancing can act as a final barrier that the pathogen will rarely be able to surpass, given that most pathogens cannot remain airborne over large distances.

For these reasons, healthcare professionals emphasize the importance of these strategies because they help reduce transmission until vaccines or drug-based treatments become available and herd immunity can be reached.
