Key Findings

*Key Findings are based on results from Wednesday, January 12th - Tuesday, January 18th, 2022.

Virtually all cases in the area are now from the Omicron variant. The Omicron variant is more than 2x as contagious as previous versions of the virus. Prior variants typically required several minutes of contact to transmit. With the Omicron variant transmission can occur in a few seconds of contact. People who are not vaccinated currently have an extremely high risk of catching and transmitting the Omicron variant to others. Vaccination, as well as booster (third) doses of an mRNA vaccine remain the most potent and durable way to protect yourself from COVID-19.                                                                 
There are an estimated 24,605 active infections that have been diagnosed by lab testing. These people can infect other people. Be aware that for every diagnosed case there are approximately 4 undiagnosed people who can also transmit the COVID-19 virus. It is therefore important to realize that you can get infected by people who are unaware they are infected, and these make up the vast majority of people infected.   
Most undiagnosed people who are infected will not be aware they carry the virus and can infect others. The time between becoming infected and having symptoms averages 5-days, and this is a period when a person is typically highly infectious. The risk of infection from people with no symptoms, or mild symptoms, is the greatest single threat to members of the community. Do not assume that a lack of symptoms in people you encounter means that they cannot transmit the COVID-19 virus to you.
Across large areas of the United States there is a significant surge in COVID-19 cases occurring, especially in areas with low vaccination rates. In these areas with extremely high infection rates the Omicron variant is predominant. This variant is much more transmissible than prior variants. Booster doses of the vaccine are recommended to prevent severe infection resulting in hospitalization and/or death. 
The community is advised to develop an evidence-based risk mitigation plan that is specific to personal risk. Those vaccinated or who have recovered from a recent infection have low risk of acquiring or transmitting COVID-19. Be aware that many people mistakenly believe that they have been infected with COVID-19 earlier. Unvaccinated people need to continue to practice prevention behaviors to avoid infection.
After vaccination it is important to continue to practice prevention practices. There are two well-known features of the vaccines for COVID-19: (1) they are not instantaneously effective and (2) one dose does not provide protection sufficient to allow immunized individuals to consider themselves immune from COVID, even after two weeks have elapsed. If you have symptoms of COVID-19 after getting immunized, it is still very possible that you acquired COVID-19, and you should self-isolate and immediately seek tested. If you have had your first vaccine dose, make sure to get your second one scheduled.
Scientific evidence is strong for the effectiveness of several risk mitigation behaviors: (1) wear a mask when around others, and avoid neck gaiters and vented masks, (2) keep a distance of no-less than 6-feet from others, more is better (3) avoid crowds, (4) wash hands frequently, (5) favor gathering with people outside over inside, and open windows (even a few inches helps) when feasible with others while inside, and (6) wear a mask and crack windows when you must travel with others in a vehicle.
There is strong evidence that transmission of the virus that causes COVID-19 is occurring via aerosols. Aerosols are very small liquid particles that are breathed out when people speak, and they can float in the air like smoke for hours. Loud talking, singing, and heavy breathing from exercise generate a significant volume of aerosol particles. As a result, indoor gatherings are risky, especially when turnover of the air is infrequent. Aerosol transmission can occur at much greater distances than 6-feet. People should assume that there is no safe distance from others indoors in poorly ventilated rooms. Multiple high-quality studies have identified indoor visits to restaurants and bars as one of the most common modes of infection.   
Testing resources are particularly strained right now given the large number of people becoming infected. Hospitals in our area are urging patients who need to be tested for COVID to seek out testing sites instead of showing up to an emergency room. You can search for a testing site located near you at this website (South Carolina DHEC website).   
Currently there is adequate capacity to manage the case load of COVID-19 admissions in area hospitals.
