COLUMBIA, S.C. - March 19th, 2026 - The South Carolina Department of Health and Environmental Control (DHEC) issued a strong advisory today, urging all residents to receive updated COVID-19 and influenza vaccines as cases of both illnesses demonstrate a concerning increase throughout the state. Public health officials are bracing for a potentially challenging peak of respiratory virus season and emphasize that preventative measures, particularly vaccination, are crucial to protecting individual health and the capacity of the state's healthcare system.

While COVID-19 is no longer considered a public health emergency in the same way it was during the height of the pandemic, the virus continues to circulate and evolve. DHEC data reveals a noticeable uptick in positive cases over the last four weeks, with hospitalizations also showing a corresponding, albeit slower, rise. This increase is attributed to newer variants that, while generally causing less severe illness in vaccinated individuals, are still capable of causing significant morbidity and mortality, especially among vulnerable populations. The current dominant strain, tentatively designated XBB.1.27.4, displays increased transmissibility and a degree of immune evasion, highlighting the need for updated vaccine formulations.

The flu season, too, is demonstrating a late surge. Traditionally, influenza activity peaks in December and January, but this year's patterns are unusual. DHEC epidemiologists suspect a combination of factors, including lower vaccination rates during the 2025-2026 season and the continued presence of lingering COVID-19 immunity impacting the typical spread of influenza, have contributed to this delayed peak. The current predominant influenza strain is A/H3N2, which historically impacts older adults and individuals with chronic health conditions more severely.

"We're seeing a convergence of both COVID-19 and influenza activity, creating a significant burden on our healthcare facilities," explained Dr. Amelia Hernandez, DHEC's State Epidemiologist, in a press conference this morning. "The updated vaccines are specifically designed to address the currently circulating variants of both viruses. They are not just boosters; they are reformulated to provide a more targeted and effective immune response. We cannot stress enough the importance of getting vaccinated, not just for your own protection, but to help protect those around you who may be more vulnerable."

DHEC's recommendation extends to all South Carolinians six months of age and older. They strongly advise getting both the updated COVID-19 vaccine and the annual flu shot. The vaccines are widely available at pharmacies, doctor's offices, and local health clinics throughout the state. DHEC is also hosting a series of mobile vaccination clinics in underserved communities to ensure equitable access.

The agency is also reiterating the importance of non-pharmaceutical interventions, such as frequent handwashing, staying home when sick, and wearing masks in crowded indoor settings, particularly for those who are immunocompromised. However, officials emphasize that these measures are most effective when used in conjunction with vaccination.

Looking ahead, DHEC is closely monitoring the situation and preparing for the possibility of future variant emergence. They are collaborating with the Centers for Disease Control and Prevention (CDC) to track viral mutations and assess the effectiveness of current vaccines. Research is also underway to develop pan-coronavirus vaccines that would offer broader and more durable protection against multiple variants.

The state's healthcare providers are also urging residents to stay informed and proactive. "We're seeing a lot of patients coming in with symptoms that could be either COVID or the flu," said Dr. David Chen, a primary care physician in Charleston. "Early diagnosis and treatment are key to preventing severe illness. Don't hesitate to seek medical attention if you're feeling unwell."

Residents can find more information about COVID-19 and flu vaccines, as well as locate vaccination sites, on the DHEC website at [ scdhec.gov ]. The site also provides information on symptoms, testing, and treatment options. DHEC encourages all South Carolinians to prioritize their health and take the necessary steps to protect themselves and their communities from these respiratory illnesses.

Furthermore, DHEC is actively working with schools and businesses to promote vaccination and provide resources for implementing workplace safety protocols.
