Those without immunity from vaccination or a recent infection (past 7-months) remain at risk, especially since viral variants that are much more transmissible are now the most common infection. Vaccination is the most potent and durable way to protect yourself from COVID-19, and vaccination currently protects against the new variants. The region has experienced a significant decline in the number of daily of COVID-19 cases per 100,000 people – but this includes a large proportion of people with immunity from vaccination and recent infection. Almost no infections are occurring among people who are fully vaccinated or had a recent infection. The few that do get infected after vaccination typically have brief asymptomatic or very mild cases. As a result, the standard metric of cases per day per 100k population is declining as fewer people are at risk. However, the risk to those who have not been vaccinated or had a recent infection is currently elevated as virtually all new infections are occurring in the shrinking group of those without immunity. Those who have had a prior infection should still get vaccinated. Be aware that many people mistakenly believe that they were infected earlier.           
This week the 7-day average of new infections decreased 8% since the prior week. Those without immunity from vaccination or a recent infection (past 7-months) are still at risk. It is important that those without immunity from vaccination or a recent infection maintain sustained vigilance in practicing behavioral prevention such as wearing masks, keeping a distance from others, avoiding indoor gatherings, and good hand hygiene.   
The Florence area experienced a significant post- winter holiday period with the number of daily cases per 100,000 population exceeding 150 per day, an extremely high level of infection. With the introduction of vaccines the case rate has diminished dramatically. The current number of infections diagnosed each day for every 100,000 people (7-day rolling average) is 3.3. One week ago, this value was 3.2. Be aware that these values can increase quickly, so it is important to remain vigilant.    
This past week there were 61 cases in the past week. In the prior week there were 66 cases. 
There are an estimated 127 active infections diagnosed by lab testing. These people can infect other people. This is down from 157 in the last weekly report. It is estimated that approximately 5 times the number of diagnosed cases go undiagnosed, yielding over 700 active cases in the area combining diagnosed and undiagnosed. 
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 was a significant surge in COVID-19 cases over and after the winter holiday period, and this has subsided in most areas. Numerous variants of the virus that have been detected throughout the US are now more than 80% of cases, and many of these are known to be more easily transmitted than the initial version of the virus. There are concerns over new surges in infections among those who have not been vaccinated in the coming months.  
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 very low risk of acquiring or transmitting COVID-19. Be aware that many people mistakenly believe that they have been infected with COVID-19 earlier. Those unvaccinated need to continue to practice prevention behaviors.
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. 
There are currently few delays in getting appointments for COVID-19 diagnostic testing, and results are being returned quickly. An exception is prior to holidays. If you plan to be tested prior to holidays be aware that delays in getting appointments and return of results may occur.   
Currently there is adequate capacity to manage the case load of COVID-19 admissions in area hospitals.

COVID-19 Projections for the MUSC Florence Medical Center

We are in the process of developing a hospital impact model, that will provide analysis of patients seeking care at MUSC Florence Medical Center over time for the current stage of the pandemic. Results will be updated as soon as they are available.
