They treat COVID-19 today with a mix of targeted antivirals, hospital-based supportive care for severe cases, and simple home care for mild illness.

Big picture

  • For most people, COVID-19 is managed at home with rest, fluids, fever control, and isolation to avoid spreading it.
  • People at higher risk (older age, chronic illnesses, weak immune system, pregnancy, etc.) may be eligible for prescription antivirals that cut the risk of hospitalization and death if started early.
  • Severe cases are treated in hospital with oxygen, anti‑inflammatory medicines, and intensive care if breathing fails.

Antiviral medicines

These drugs directly slow the virus’s ability to copy itself and work best when started within the first few days of symptoms.

  • Paxlovid (nirmatrelvir + ritonavir)
    • Taken as pills at home for 5 days.
* Preferred option for many high‑risk adults and some teens; large trials showed it reduced hospitalization and death by roughly 85–90% in high‑risk outpatients when given early.

* Not for everyone: it interacts with many common medicines and cannot be used in some kidney or liver problems, so a clinician has to check carefully first.
  • Remdesivir (Veklury)
    • An antiviral given by IV (drip in a vein), often for 3 consecutive days for outpatients at high risk, or longer in hospital.
* Also shown to lower the chance of hospitalization and death when started within about 7 days of symptom onset in high‑risk people.
  • Molnupiravir (Lagevrio)
    • Oral antiviral for adults who cannot receive other preferred options; taken for 5 days.
* Considered a “backup” choice in some guidelines because trial data show benefit but generally less than Paxlovid, and there are pregnancy‑related safety cautions.
  • Monoclonal antibodies
    • Lab‑made antibodies (for example sotrovimab in some places) have been used in high‑risk patients, but many earlier products lost effectiveness as the virus evolved; availability and recommendations now vary by country and current variants.

Hospital treatment for severe COVID

When COVID-19 causes low oxygen levels or organ failure, treatment focuses on supporting the body and calming the immune overreaction.

  • Oxygen therapy
    • Extra oxygen through nasal prongs, masks, or high‑flow devices is standard when blood oxygen drops.
* If lungs are badly affected, some patients need mechanical ventilation (a breathing machine) in intensive care.
  • Anti‑inflammatory and immune‑modulating drugs
    • Steroids like dexamethasone are used in patients needing oxygen, because they reduce the harmful inflammation that can damage lungs.
* Other agents such as baricitinib (a JAK inhibitor) or IL‑6 blockers may be added in some severe cases to fine‑tune the immune response, guided by specific hospital protocols.
  • Antivirals in hospital
    • Remdesivir can be continued or started in hospitalized patients, especially early in the course of illness, to limit viral replication.
  • General supportive care
    • Care includes fluids, treatment of blood clots, management of complications like heart strain or kidney injury, and sometimes prone positioning (lying on the stomach) to improve oxygen levels.

Home care for mild COVID

For people who are otherwise healthy and not at high risk, treatment is usually about symptom relief and preventing spread.

  • Rest, hydration, and over‑the‑counter medicines such as paracetamol/acetaminophen or ibuprofen for fever and aches are commonly recommended.
  • Monitoring for warning signs is crucial: trouble breathing, chest pain, confusion, or lips/face turning blue or very pale are reasons to seek urgent medical care.
  • Staying home while infectious, improving ventilation, and masking around others help protect family and community.

What has changed over time

Treatment has evolved since the early pandemic, and recommendations continue to be updated as new variants and studies appear.

  • Some therapies used early on (certain monoclonal antibodies, or drugs later shown not to help) have been dropped or restricted as evidence grew.
  • Antivirals like Paxlovid and outpatient remdesivir have become central tools for people at high risk when used quickly after symptom onset.
  • Vaccination and prior infections now mean a larger share of infections are milder, but high‑risk groups still benefit a lot from timely treatment.

Important: Exact options and eligibility differ by country, age, pregnancy status, other illnesses, and your current medications. Anyone with a positive test and risk factors (age 50+, chronic disease, or weakened immunity) should contact a healthcare professional quickly—often within 5 days of symptoms—to ask specifically about antiviral treatment.
