If you have COVID, the most important steps are to test to confirm, rest at home, manage your symptoms with over-the-counter medications, and determine whether you qualify for antiviral treatment within the first five days. Most people recover at home without medical intervention, but acting quickly on a few key decisions can shorten your illness and protect the people around you.
Confirm With a Test
If you have symptoms like fever, cough, sore throat, or body aches, take a rapid antigen test right away. A negative result on the first test doesn’t rule out COVID, especially early in an infection. If that first test comes back negative, test again at least 48 hours later. Two negative tests spaced 48 hours apart give you much more confidence in the result.
If you were exposed to someone with COVID but don’t have symptoms yet, wait at least five full days after your exposure before testing. Testing too early in that scenario often produces a false negative because viral levels haven’t built up enough to detect.
Find Out If You Qualify for Antivirals
This is the most time-sensitive decision. Prescription antiviral treatment needs to start within five days of your first symptoms to be effective, so don’t wait to look into it. You’re most likely to qualify if you’re over 65, have multiple chronic health conditions, are immunocompromised, or aren’t up to date on COVID vaccinations. Risk increases substantially for people over 75 and for those on medications that suppress the immune system, such as chemotherapy.
Contact your doctor, an urgent care clinic, or a telehealth service as soon as you test positive if any of those risk factors apply to you. The standard antiviral course is a five-day regimen taken twice daily. Even if you’re not sure whether you qualify, it’s worth asking, because clinicians can assess your individual risk and make a judgment call.
You may have heard about “rebound,” where symptoms or viral levels return after finishing the antiviral course. Clinical trial data shows viral rebound occurred in roughly 8% of people who took the antiviral, compared to about 6% of people who took a placebo. The difference was small and not statistically significant in most analyses, meaning rebound appears to be a feature of COVID itself rather than a side effect of treatment.
Managing Symptoms at Home
Most COVID cases are mild enough to treat at home the same way you’d handle a bad cold or flu. Acetaminophen and ibuprofen both help with fever, headaches, and body aches. Stay well hydrated, especially if you have a fever, and rest as much as your body is asking you to. There’s no special COVID-specific remedy needed for mild illness.
For congestion and cough, standard over-the-counter cold medications can take the edge off. Sleep with your head slightly elevated if breathing feels easier that way. Most people start turning the corner within a week, though fatigue can linger longer.
Protecting Others in Your Home
COVID spreads through the air, so ventilation is your strongest tool for protecting housemates. Open windows when weather allows, and if you have a portable air cleaner with a HEPA filter, put it in the room where the sick person is isolating. Choose a unit rated for the size of that room, and position it so the airflow doesn’t blow directly from one person to another.
If someone in the household is especially vulnerable (elderly, immunocompromised, or has a serious chronic condition), place the air cleaner in the room where that person spends the most time instead. Wearing a well-fitting mask when you need to leave your isolation room, washing your hands frequently, and keeping shared bathroom surfaces clean all reduce the odds of spreading the virus to family members.
Emergency Warning Signs
A small percentage of people develop severe illness, and knowing the red flags matters. Call 911 or head to the emergency room if you experience any of the following:
- Trouble breathing or shortness of breath that doesn’t improve with rest
- Persistent pain or pressure in the chest
- New confusion or difficulty thinking clearly
- Inability to wake or stay awake
- Color changes in the lips, nail beds, or skin, which may appear pale, gray, or blue depending on skin tone
If you call 911, let the operator know you have or may have COVID so the responding team can prepare.
Getting Back to Normal Activity
How quickly you can return to exercise and daily routines depends on how sick you were. If you tested positive but never developed symptoms, you can generally resume exercise after three or four symptom-free days. If your symptoms were mild and didn’t involve your heart or lungs, you can start easing back in once the illness has run its course and you feel symptom-free.
The key word is “easing.” Start at a lower intensity than your usual workouts and build back gradually. If you experienced significant heart or lung involvement during your illness, get clearance from your doctor before returning to exercise. People diagnosed with inflammation of the heart muscle should wait three to six months before resuming physical activity.
Watch for Lingering Symptoms
Most people recover fully, but some develop persistent symptoms that last weeks, months, or in rare cases, years. These can include fatigue, brain fog, shortness of breath, sleep problems, and a range of other issues that don’t follow an obvious pattern. The majority of people with lingering symptoms see significant improvement within three months, but the timeline varies widely.
If you have symptoms that persist well beyond your initial illness, are hard to explain, or are affecting your daily life, bring them up with your healthcare provider. Some people experience overlapping symptoms that benefit from a coordinated care approach rather than treating each issue in isolation.
