If you just tested positive for COVID-19, the most important step is to stay home and away from others until your symptoms have been improving for at least 24 hours and any fever has been gone for 24 hours without fever-reducing medication. Most people have mild illness and recover at home without needing medical attention, but there are a few things worth doing in the first day or two that can make a real difference in how you feel and how quickly you bounce back.
How Long to Stay Home
The CDC’s current guidance moves away from a fixed number of isolation days. Instead, the rule is symptom-based: stay home while you’re feeling sick, and return to normal activities once your symptoms have been improving overall for at least 24 hours, with no fever during that time (and no help from acetaminophen or ibuprofen to keep the fever down).
Once you’re back out, take extra precautions for the next five days. That means wearing a well-fitting mask around others, keeping distance when possible, improving airflow in shared spaces, and practicing good hand hygiene. You’re still shedding some virus during this window, even though you feel better.
If you want more certainty about whether you’re still contagious, rapid antigen tests can help. A negative rapid test is a reasonable signal that your viral load has dropped significantly. Some people test negative within five or six days; others continue testing positive for a week or more.
Check Whether You Qualify for Antiviral Treatment
This is the most time-sensitive decision after a positive test. Prescription antivirals work best when started early in the illness, ideally within the first five days of symptoms. They’re designed for people at higher risk of severe COVID, including adults over 65, people with conditions like diabetes, heart disease, obesity, chronic lung disease, or a weakened immune system, and anyone whose doctor judges them at elevated risk.
You’ll need a prescription, which means contacting your doctor, an urgent care clinic, or a telehealth provider quickly. If you have risk factors, don’t wait to see if symptoms worsen before calling. The treatment window is narrow and the drugs are less effective once the virus has had time to multiply.
One thing to be aware of: somewhere between 6% and 32% of people who take the most commonly prescribed antiviral experience a “rebound,” where symptoms or a positive test return a few days after finishing the course. Rebound cases are generally mild, but they can be frustrating. This doesn’t mean the medication failed. It still significantly reduces the risk of hospitalization in high-risk individuals.
Managing Symptoms at Home
For the majority of people, COVID-19 feels like a bad cold or flu and responds to the same basic care. Acetaminophen and ibuprofen both help with fever, headaches, and body aches. Stay well hydrated, especially if you have a fever, since your body loses fluid faster when your temperature is elevated. Rest as much as you can, even if your symptoms feel manageable. Pushing through often extends recovery time.
Sore throat lozenges, honey in warm water, and nasal saline rinses can help with upper respiratory symptoms. If congestion is significant, a standard decongestant may help you sleep. There’s no special COVID-specific remedy needed for mild cases.
Protecting Others in Your Household
Household transmission is common, but you can reduce the odds significantly with a few practical steps. If possible, stay in a separate room and use a separate bathroom. Wear a mask when you need to be in shared spaces.
Ventilation makes a surprisingly big difference. Open windows, even cracked slightly, to bring in fresh outdoor air. If you have a central HVAC system, switch the fan setting from “auto” to “on” so it runs continuously and filters air even when the heat or AC isn’t actively cycling. Use pleated filters rather than basic flat ones for better filtration. A portable HEPA air purifier in the room where you’re isolating, or in shared living spaces, adds another layer of protection. Choose one rated for the square footage of the room.
Turn on exhaust fans in bathrooms and kitchens, and keep them running. If you place a fan near an open window, point it outward to push air (and virus particles) outside rather than toward other people in the home. Keep shared time in common areas short, and gather in larger rooms where people can spread out.
Warning Signs That Need Emergency Care
Most people recover without complications, but certain symptoms signal that the infection is becoming dangerous. Call 911 or go to an emergency room if you experience:
- Trouble breathing or shortness of breath at rest
- Persistent pain or pressure in your chest
- New confusion or difficulty thinking clearly
- Inability to stay awake or difficulty being roused from sleep
- Color changes in the lips, nail beds, or skin, such as pale, gray, or blue tones
These symptoms can develop suddenly, sometimes after a few days of feeling like the illness is improving. If you live alone, let a friend or family member know you’re sick so someone checks on you daily.
What Recovery Looks Like
Most mild cases resolve within one to two weeks. Fatigue and a lingering cough often hang on longer than other symptoms, sometimes for several weeks, even when you’re no longer contagious. This is normal and doesn’t necessarily mean something is wrong.
If symptoms persist beyond four weeks, or if new symptoms appear after you thought you’d recovered (brain fog, heart palpitations, exercise intolerance), that may point to a longer recovery pattern sometimes called long COVID. Mention it to your doctor so they can help you manage it rather than assuming it will resolve on its own.
