If you think you have COVID, the first step is to take a rapid antigen test and isolate yourself from others while you figure out your status. Most people recover at home with rest and basic over-the-counter medication, but acting quickly matters, especially if you’re at higher risk for severe illness and may need a prescription antiviral within the first five days of symptoms.
Recognize the Current Symptoms
COVID symptoms today look a bit different from what circulated in earlier years. The most common signs with recent variants include a severe sore throat (often described as sharp or stabbing, especially when swallowing), persistent fatigue, mild cough, nasal congestion or runny nose, fever, muscle aches, and sneezing. Some people also experience digestive symptoms like nausea or diarrhea, though that’s less common. The intense sore throat tends to hit early and is often the symptom that sends people reaching for a test.
These symptoms overlap heavily with the flu and other respiratory viruses. A rapid test is the only reliable way to tell the difference at home.
When and How to Test
Use a rapid antigen test as soon as you notice symptoms. If the result is negative but you still feel sick, don’t assume you’re in the clear. The FDA recommends two negative antigen tests taken 48 hours apart for people with symptoms before you can confidently rule out COVID. If you were exposed but don’t have symptoms, the bar is even higher: three negative tests, each 48 hours apart.
A faint line on a rapid test counts as a positive result. It means you have infectious viral particles in your body, just at a lower level than a bold dark line would indicate. A faint line could mean you’re at the very beginning of an infection and viral load is still building, or that you’re on the tail end of one. Either way, treat it as positive.
Managing Symptoms at Home
Most people with COVID have mild illness and recover without medical intervention. Over-the-counter pain relievers like acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) can bring down a fever and ease body aches, sore throat pain, and headaches. Beyond medication, the basics matter: drink plenty of fluids, rest as much as your body asks for, and use honey or throat lozenges for that sore throat.
Keep a thermometer handy and monitor your temperature. A fever that breaks and stays gone for 24 hours without medication is one of the key markers that you’re turning a corner.
Who Should Seek Prescription Treatment
Antiviral treatment exists for people at higher risk of developing severe COVID. You’re eligible if you’re 50 or older, or younger with a medical condition that raises your risk. The treatment works best when started within five days of your first symptoms, so if you fall into a high-risk category, contact your doctor or a telehealth provider quickly rather than waiting to see how you feel.
The list of conditions that increase your risk is broader than many people realize. It includes:
- Diabetes (type 1 or type 2)
- Heart conditions (heart failure, coronary artery disease, possibly high blood pressure)
- Chronic lung disease (moderate-to-severe asthma, COPD, pulmonary hypertension)
- Chronic kidney or liver disease at any stage
- Being overweight or obese (BMI of 25 or higher, with risk increasing sharply at higher BMI)
- A weakened immune system (from cancer treatment, organ transplant medications, or long-term corticosteroid use)
- Pregnancy
- Current or former smoking
- Mental health conditions including depression and schizophrenia spectrum disorders
- HIV, cancer, cystic fibrosis, sickle cell disease, or dementia
Age alone is a significant factor. More than 81% of COVID deaths occur in people over 65. If you’re in that age group, treatment is worth pursuing even if your symptoms feel mild at first.
One thing to know about antivirals: roughly one in five people who take them experience what’s called “rebound,” where symptoms improve and a test turns negative, then the virus comes back with a positive test and potentially contagious virus a few days later. Harvard Medical School researchers found the rebound rate was 20.8% among those taking the antiviral compared to just 1.8% without it. Rebound doesn’t mean the drug failed, and most rebound cases are still mild, but it’s worth being aware of so you’re not caught off guard.
When to Call 911
Most COVID cases stay mild, but certain warning signs mean you need emergency care immediately. Call 911 if you or someone you’re caring for develops trouble breathing, persistent chest pain or pressure, new confusion, or an inability to wake up or stay awake. Skin, lips, or nail beds turning pale, gray, or blue (depending on skin tone) is another signal that oxygen levels have dropped dangerously. When you call, let the operator know COVID is suspected so the medical team can prepare.
How Long to Isolate
Current CDC guidance says you can return to normal activities when both of these have been true for at least 24 hours: your symptoms are improving overall, and you haven’t had a fever without the help of fever-reducing medication. For many people, that means roughly three to five days at home, though it varies.
Clearing that 24-hour threshold doesn’t mean you’re no longer contagious. Your body is still working to eliminate the virus. For the next five days after you resume activities, take extra precautions: wear a well-fitting mask around others, keep your distance when possible, improve ventilation in shared spaces, and wash your hands frequently. After that five-day period, you’re typically much less likely to spread the virus to anyone.
Protecting the People Around You
While you’re symptomatic, stay in a separate room from household members if you can. Use a separate bathroom if one is available. Open windows or run an air purifier to improve airflow. If you need to be in shared spaces, a well-fitting N95 or KN95 mask significantly reduces transmission risk for both you and the people nearby.
Let close contacts know you’ve tested positive so they can monitor themselves and test if symptoms develop. They should watch for symptoms for 10 days after their last exposure to you and consider testing even without symptoms, using that three-test protocol spaced 48 hours apart.
