What is community spread and how does it work?

In: Biology
[ad_2]

Community spread just means a person was infected by another person within the community (for example, a town or city), rather than that person being infected by someone traveling to the community or that person traveling outside the community and being infected. People talk about community spread because when that is happening, it means that the spread will be very hard to stop. If infections are still occurring just from people traveling, it can be possible to isolate those people and the people they’ve been in contact with and potentially stop the disease spreading through the whole community.
