Pettis County Health Center Administrator JoAnn Martin supplied the most recent update from the Centers for Disease Control on Tuesday afternoon. Pettis County is in a high-transmission, low-vaccination area.

Top five things to know about COVID-19 and the Delta variant:

1. Getting vaccinated prevents severe illness, hospitalization, death; it also helps reduce the spread of the virus in communities.
 Unvaccinated individuals should get vaccinated and continue masking until they are fully vaccinated.
 With the Delta variant, this is more urgent than ever. The highest spread of cases and severe outcomes is happening in places with low vaccinations rates.

2. Data show Delta is different than past versions of the virus: it is much more contagious.
 Some vaccinated people can get Delta in a breakthrough infection and may be contagious.
 Even so, vaccinated individuals represent a very small amount of transmission occurring around the country.
 Virtually all hospitalizations and deaths continue to be among the unvaccinated.

3. In areas with substantial and high transmission, CDC recommends that everyone (including fully vaccinated individuals) wear a mask in public indoor settings to help prevent spread of Delta and protect others.

4. CDC recommends that community leaders encourage vaccination and masking to prevent further outbreaks in areas of substantial and high transmission.

5. CDC recommends universal indoor masking for all teachers, staff, students, and visitors to K-12 schools, regardless of vaccination status. Children should return to full-time in-person learning in the fall with layered prevention strategies in place.
