Most people with the flu are contagious from about one day before symptoms appear until five to seven days after getting sick. Children and people with weaker immune systems can spread it a little longer. A rapid flu test at CareFirst can confirm the flu and help your provider decide whether antiviral medication is right for you.

What Illness Treatment Covers
Urgent care is the comfortable middle ground between your primary care office and the emergency room. It is built for illnesses that cannot wait a few days but are not severe enough to need emergency care. Our providers can evaluate your symptoms, run rapid tests right in the clinic, and get you on the mend, all in one visit. No appointment and no referral needed.
Common Illnesses We Treat
Here are the everyday illnesses we see and treat most often, grouped by how they tend to show up.
Cold, flu, and respiratory infections. Coughs, congestion, body aches, and fever are some of the most common reasons people walk in. We can run a rapid flu or COVID-19 test, check for bronchitis, and order a chest X-ray if pneumonia is a concern. Good to know: the flu is generally contagious from about one day before symptoms start until five to seven days after, and a typical cold runs its course in seven to ten days.
Sinus, throat, and ear concerns. Sinus pressure, a scratchy or itchy throat, and ear pain are easy to treat and easy to test for. A rapid strep test takes only a few minutes and tells us whether antibiotics make sense. We commonly treat sinus infections, strep throat, tonsillitis, laryngitis, and ear infections in both kids and adults. For quick relief from sinus pressure, warm compresses, saline rinses, and staying hydrated help while your body fights the infection.
Stomach and digestive illness. A stomach bug or norovirus can bring on nausea, vomiting, diarrhea, and cramping. We can assess your symptoms, treat dehydration with IV fluids if needed, and help you feel steady again. Norovirus usually clears within one to three days, and you can stay contagious for a couple of days after you feel better, so rest and handwashing matter.
Infections and other common illnesses. We also treat urinary tract infections, pink eye, skin infections like cellulitis, hand, foot, and mouth disease, RSV, and mild allergic reactions. For a suspected UTI, our team can confirm it with a simple urine test and start treatment the same day. Learn more about our UTI treatment.

Same-Day Testing On Site
You do not have to visit a separate lab to find out what is going on. Our clinics offer on-site lab testing with results while you wait, including rapid strep, rapid flu, COVID-19, urinalysis, mono tests, and basic blood work.

Frequently Asked Questions About Illness Treatment
The infection itself usually is not spread person to person, but the viruses that often trigger sinus infections, like the common cold, can be. If a virus is behind your symptoms, normal precautions like handwashing and covering coughs help protect the people around you.
Viral pink eye often clears on its own in one to two weeks, while bacterial pink eye can improve within a few days of starting antibiotic drops. Because pink eye spreads easily, it is worth getting checked so you know which type you have and how to keep from passing it along.
Most fevers from common viral illnesses last two to three days. Call a provider or come in if a fever climbs above 103°F, lasts more than three days, or comes with a stiff neck, rash, confusion, or trouble breathing. Any fever in an infant under three months old needs immediate medical attention.
Yes. Our clinics run rapid strep, flu, and COVID-19 tests on site with results while you wait. See our full lab testing page for the complete list.
