If you’ve tested positive for COVID-19 or strongly suspect you have it, the most important steps are to stay home, manage your symptoms, and figure out quickly whether you qualify for antiviral treatment. Most people recover at home within a week or two, but acting fast in the first few days can make a real difference, especially if you’re at higher risk for serious illness.
Confirm Your Test Results
If you have symptoms, take an at-home rapid test right away. A positive result is reliable, but a negative result doesn’t always mean you’re in the clear. If your first test comes back negative, test again 48 hours later. It can take a couple of days for viral levels to climb high enough for a rapid test to detect them.
If you were exposed to someone with COVID but don’t have symptoms yet, wait at least five full days after the exposure before testing. Testing too early often produces a false negative.
Stay Home and Limit Contact
As soon as you know you’re sick, separate yourself from other people in your household as much as possible. Sleep in a different room if you can. Use a separate bathroom if one is available. Wear a high-quality mask (N95 or KN95) when you need to be in shared spaces.
Stay home and away from others until your respiratory symptoms are clearly improving and you’ve been fever-free for at least 24 hours without using fever-reducing medication. Even after that point, wearing a mask around others for a few more days adds an extra layer of protection.
Improve Airflow in Your Home
COVID spreads through the air, so ventilation is one of the most effective tools for protecting the people you live with. Open windows on opposite sides of your home and keep interior doors open to create cross-ventilation. If you have double-hung windows, opening the top sash on one and the bottom sash on another encourages better airflow.
Run your HVAC system fan continuously rather than on the auto setting, since it only filters air while the fan is running. If possible, upgrade to a MERV 13 filter or the highest-rated filter your system can handle. A portable air purifier with a HEPA filter placed in the room where you’re spending the most time also helps. Point any fans or air cleaners so they don’t blow air directly from one person toward another.
Manage Your Symptoms at Home
Most COVID cases are mild and don’t require anything beyond basic home care. For fever, body aches, and headaches, acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) both work well. Follow the dosing instructions on the package.
Beyond medication, the basics matter more than people expect. Drink plenty of fluids, particularly water, broth, and drinks with electrolytes. Rest as much as your body asks for. A humidifier or a steamy shower can ease congestion. Honey in warm water or tea can soothe a sore throat and calm a cough (for adults and children over one year old). Keep a thermometer handy and check your temperature a couple of times a day so you can track whether your fever is improving.
If you have a pulse oximeter, use it periodically. A reading of 95% or above is normal. Anything consistently below 94% deserves a call to your doctor.
Find Out If You Qualify for Antiviral Treatment
This is the most time-sensitive step. Antiviral medication can significantly reduce your risk of ending up in the hospital, but it works best when started within the first five days of symptoms. Don’t wait to see if you get worse. Call your doctor or a telehealth service as soon as you test positive.
You’re eligible if you’re 18 or older (or at least 12 and weighing at least 88 pounds), have mild to moderate symptoms, and have at least one risk factor for severe disease. The list of qualifying conditions is longer than most people realize. It includes:
- Obesity (BMI over 30, or even being overweight with a BMI over 25)
- Diabetes (type 1, type 2, or gestational)
- Asthma or other chronic lung conditions like COPD or pulmonary hypertension
- Heart conditions such as heart failure, coronary artery disease, or cardiomyopathies
- Chronic kidney or liver disease
- Pregnancy or recent pregnancy
- Current or former smoking
- Weakened immune system from medications, organ transplant, or conditions like HIV
- Mental health conditions including depression and schizophrenia spectrum disorders
- Neurologic conditions like dementia or Parkinson’s disease
- Cancer, particularly blood cancers
- Physical inactivity
Physical inactivity and depression are on that list, which surprises many people. If any of these apply to you, don’t hesitate to ask about treatment. You don’t need to be severely ill to qualify. In fact, you shouldn’t be hospitalized at the time of treatment, as antivirals are designed for people managing symptoms at home.
Know the Emergency Warning Signs
While most people recover without problems, certain symptoms mean you need emergency care immediately. Call 911 or go to an ER if you experience:
- Trouble breathing or shortness of breath at rest
- Persistent pain or pressure in the chest
- New confusion or difficulty thinking clearly
- Inability to wake up or stay awake
- Lips, nail beds, or skin turning pale, gray, or blue
If you call 911, tell the dispatcher that the person may have COVID-19 so the responding team can take appropriate precautions.
Watch for Symptom Rebound
Some people start to feel better and then experience a return of symptoms two to eight days after their initial recovery. This can happen whether or not you took antiviral medication. Symptoms during a rebound are typically mild, and no additional antiviral treatment is currently recommended.
If your symptoms come back, treat the rebound the same way you treated the initial infection: stay home, isolate from others, and manage symptoms with rest and over-the-counter medications. You can be contagious again during a rebound, so follow the same precautions you used the first time around.
Ease Back Into Activity Slowly
One of the most common mistakes people make is jumping back into exercise or a full work schedule the moment they feel better. Pushing too hard too soon can trigger prolonged fatigue and may increase the risk of lingering symptoms.
Start with short, low-intensity activities. Walking for 10 to 15 minutes is a reasonable first step. If you feel fine the next day, gradually increase your duration and effort. Exercises done in a seated or reclined position, like stationary cycling or rowing, are easier on your cardiovascular system during early recovery than upright activities like running. The American Heart Association recommends this graduated approach, noting that building back over weeks rather than days leads to better outcomes.
If you notice that even mild exertion leaves you feeling significantly worse the following day, that’s a sign your body isn’t ready. Dial it back and give yourself more time. Persistent shortness of breath, chest pain, or a racing heart during light activity warrants a call to your doctor, as these can occasionally signal cardiac involvement that needs evaluation.
