Respiratory illness in South Carolina: when to stay home, and what to do about it

Most coughs don't come with a label. A fever in Myrtle Beach could be COVID-19, flu, RSV or a plain cold, and the first few days often look the same. That's why current CDC guidance treats common respiratory viruses together.

The basic rule: stay home and away from others while you're sick. Go back to normal activities once your symptoms are improving overall and you've been fever-free for at least 24 hours without fever-reducing medicine, then take extra care for the next five days. It sounds simple. It gets complicated when illness collides with a school attendance policy, a shift you can't cover, or a court date.

This section is about those collisions. We cover the public-health side clearly, point you to the right person for everything else, and flag the emergency warning signs that should never wait.

A question we hear a lot

What should I know before getting into South Carolina public health?

Start with who issues the guidance. The South Carolina Department of Public Health (DPH) handles state data and local recommendations, while the CDC sets national guidance on COVID-19, flu and RSV. Check the date on anything you read, because respiratory-virus advice changes with new evidence and new seasons.
