During many epidemics, <u>healthcare </u>professionals emphasize the importance of community mitigation strategies, such as wearing masks, frequent hand-washing, and social distancing because these strategies help <u>reduce </u><u>transmission </u><u>even when drug-based treatments and vaccines are unavailable.</u>
It is of <u>vital </u>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<u> eliminate the presence of a </u><u>pathogen</u> <u>from the surface of your hands</u>, 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 <u>final barrier</u> that the pathogen will rarely be able to surpass, given that most pathogens <u>cannot remain airborne over large distances. </u>
For these reasons, healthcare professionals emphasize the importance of these strategies because they help reduce transmission <u>until vaccines or drug-based treatments become available and </u><u>herd immunity </u><u>can be reached. </u>

Explanation
to be completely honesty i have no knowledge if learning the current benefactor of the object asked in this particular question.
Answer:
Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell. Indeed, apart from random mutations, each successive duplicate cell will have the same genetic composition as its parent, due to the inheritance of the same chromosome set and similar biological environment. This works well for replacing damaged tissue or for growth and expansion from an embryonic state. Because the genes contained in the duplicate chromosomes are transferred to each successive cellular generation, all mitotic progeny are genetically similar. However, there are exceptions. For example, there are genetic variations that arise in clonal species, such as bacteria, due to spontaneous mutations during mitotic division. Furthermore, chromosomes are sometimes replicated multiple times without any accompanying cell division. This occurs in the cells of Drosophila larvae salivary glands, for example, where there is a high metabolic demand. The chromosomes there are called polytene chromosomes, and they are extremely large compared to chromosomes in other Drosophila cells. These chromosomes replicate by undergoing the initial phases of mitosis without any cytokinesis (Figure 2). Therefore, the same cell contains thick arrangements of duplicate chromosomes side by side, which look like strands of very thick rope. Scientists believe that these chromosomes are hyper-replicated to allow for the rapid and copious production of certain proteins that help larval growth and metamorphosis
