Symptoms range from mild and cold-like to severe and life-threatening.\n\nAdvertisement\n\nCleveland Clinic is a non-profit academic medical center. Advertising on our site helps support our mission. We do not endorse non-Cleveland Clinic products or services. [Policy](https:\/\/health.clevelandclinic.org\/advertising)\n\nCoronaviruses have typically caused [common colds](https:\/\/my.clevelandclinic.org\/health\/diseases\/12342-common-cold). But in 2019, a new coronavirus, SARS-CoV-2, started infecting humans and causing severe illness. At the peak of the pandemic — when COVID was spreading around the world — [tens of thousands](https:\/\/pubmed.ncbi.nlm.nih.gov\/35452402\/) of people were hospitalized every day in the U.S. alone. Millions of people have died.\n\nMedical professionals’ understanding has grown a lot since the start of the pandemic. The virus itself keeps changing — we’ve gone through variants alpha, beta, gamma, delta and now omicron. Scientists have developed treatments and [vaccines](https:\/\/my.clevelandclinic.org\/health\/treatments\/24135-vaccines) that have reduced the number of people ending up in the hospital.\n\nBut COVID isn’t “over.” It can still make you severely ill, cause symptoms that last months or years, and be fatal.\n\n## Symptoms and Causes\n### Symptoms of COVID-19\nCOVID symptoms include:\n\n- [Fever](https:\/\/my.clevelandclinic.org\/health\/symptoms\/10880-fever)\n- [Sore throat](https:\/\/my.clevelandclinic.org\/health\/diseases\/8274-sore-throat-pharyngitis)\n- [Headache](https:\/\/my.clevelandclinic.org\/health\/diseases\/9639-headaches)\n- Tiredness ([fatigue](https:\/\/my.clevelandclinic.org\/health\/symptoms\/21206-fatigue))\n- [Body aches](https:\/\/my.clevelandclinic.org\/health\/symptoms\/myalgia-muscle-pain)\n- [Chills](https:\/\/my.clevelandclinic.org\/health\/symptoms\/21476-chills)\n- [Stuffy](https:\/\/my.clevelandclinic.org\/health\/diseases\/17980-nasal-congestion) or [runny nose](https:\/\/my.clevelandclinic.org\/health\/symptoms\/17660-runny-nose)\n- [Cough](https:\/\/my.clevelandclinic.org\/health\/symptoms\/17755-cough)\n- [Shortness of breath](https:\/\/my.clevelandclinic.org\/health\/symptoms\/16942-dyspnea)\n- [Loss of](https:\/\/my.clevelandclinic.org\/health\/symptoms\/16708-loss-of-taste-and-smell) or [altered](https:\/\/my.clevelandclinic.org\/health\/diseases\/22047-dysgeusia#:~:text=Dysgeusia%20is%20a%20taste%20disorder,medication%20or%20poor%20oral%20hygiene.) sense of smell and taste\n- Difficulty thinking and focusing ([brain fog](https:\/\/my.clevelandclinic.org\/health\/symptoms\/brain-fog))\n- Digestive symptoms, like [diarrhea](https:\/\/my.clevelandclinic.org\/health\/diseases\/4108-diarrhea), [nausea](https:\/\/my.clevelandclinic.org\/health\/symptoms\/nausea) and [vomiting](https:\/\/my.clevelandclinic.org\/health\/symptoms\/vomiting)\n\nSome people have no symptoms but can still spread the virus.\n\n### COVID causes\nSARS-CoV-2 virus causes COVID. It’s a type of coronavirus, a group of viruses that also cause common colds. But this isn’t the first time a coronavirus has caused serious illness. [SARS](https:\/\/my.clevelandclinic.org\/health\/diseases\/10856-severe-acute-respiratory-syndrome-sars), a severe respiratory disease that spread between 2002 and 2004, was also a coronavirus.\n\nAdvertisement\n\nCOVID spreads through respiratory droplets. This means you can get it from coughing, sneezing and talking. You might also get it from touching contaminated objects and surfaces.\n\n#### Risk factors\nYou’re at an increased risk of being hospitalized with COVID-19 if you:\n\n- Are over 65\n- Are [pregnant](https:\/\/my.clevelandclinic.org\/health\/articles\/pregnancy)\n- [Smoke](https:\/\/my.clevelandclinic.org\/health\/articles\/17488-smoking) or used to smoke\n- Have received a solid organ or [stem cell transplant](https:\/\/my.clevelandclinic.org\/health\/treatments\/22567-stem-cell-transplants)\n\nYou’re also at an increased risk if you have:\n\n- A blood disorder such as [sickle cell disease](https:\/\/my.clevelandclinic.org\/health\/diseases\/12100-sickle-cell-disease) or [thalassemia](https:\/\/my.clevelandclinic.org\/health\/diseases\/14508-thalassemias)\n- Cancer\n- Cerebrovascular disease, such as [stroke](https:\/\/my.clevelandclinic.org\/health\/diseases\/5601-stroke)\n- Chronic conditions that affect your lungs, kidneys, liver or heart\n- Congenital conditions like [cerebral palsy](https:\/\/my.clevelandclinic.org\/health\/diseases\/8717-cerebral-palsy) or [Down syndrome](https:\/\/my.clevelandclinic.org\/health\/diseases\/17818-down-syndrome)\n- Diabetes (Type 1 or Type 2)\n- [HIV\/AIDS](https:\/\/my.clevelandclinic.org\/health\/diseases\/4251-hiv-aids) or a [compromised (weakened) immune system](https:\/\/my.clevelandclinic.org\/health\/diseases\/immunocompromised)\n- Mental health conditions, such as [depression](https:\/\/my.clevelandclinic.org\/health\/diseases\/9290-depression) or [schizophrenia](https:\/\/my.clevelandclinic.org\/health\/diseases\/4568-schizophrenia) spectrum disorders\n- Neurological conditions, like [dementia](https:\/\/my.clevelandclinic.org\/health\/diseases\/9170-dementia) or [Alzheimer’s disease](https:\/\/my.clevelandclinic.org\/health\/diseases\/9164-alzheimers-disease)\n- [Obesity](https:\/\/my.clevelandclinic.org\/health\/diseases\/11209-weight-control-and-obesity)\n- [Substance use disorders](https:\/\/my.clevelandclinic.org\/health\/diseases\/16652-drug-addiction-substance-use-disorder-sud) such as alcohol, opioid or cocaine use disorder\n- [Tuberculosis](https:\/\/my.clevelandclinic.org\/health\/diseases\/11301-tuberculosis)\n### Complications of COVID\nCOVID can cause serious complications, even if you don’t feel very sick. These include:\n\n- [Pneumonia](https:\/\/my.clevelandclinic.org\/health\/diseases\/24002-covid-pneumonia)\n- [Acute respiratory distress syndrome](https:\/\/my.clevelandclinic.org\/health\/diseases\/15283-acute-respiratory-distress-syndrome-ards) (ARDS)\n- [Blood clots](https:\/\/my.clevelandclinic.org\/health\/body\/17675-blood-clots), including [pulmonary embolism](https:\/\/my.clevelandclinic.org\/health\/diseases\/17400-pulmonary-embolism) (PE) or [deep vein thrombosis](https:\/\/my.clevelandclinic.org\/health\/diseases\/16911-deep-vein-thrombosis-dvt) (DVT)\n- Heart inflammation ([myocarditis](https:\/\/my.clevelandclinic.org\/health\/diseases\/22129-myocarditis)\/[pericarditis](https:\/\/my.clevelandclinic.org\/health\/diseases\/17353-pericarditis))\n- [Cardiac arrest](https:\/\/my.clevelandclinic.org\/health\/diseases\/21736-cardiac-arrest)\n- [Multisystem inflammatory syndrome in children](https:\/\/my.clevelandclinic.org\/health\/diseases\/24592-multisystem-inflammatory-syndrome-in-children) (MIS-C)\n- [Long COVID](https:\/\/my.clevelandclinic.org\/health\/diseases\/25111-long-covid), a condition where pain, extreme fatigue and other symptoms last for months or years after a COVID infection\n\n## Diagnosis and Tests\n### How doctors diagnose COVID\nHealthcare providers diagnose COVID by swabbing your nose with a soft-tipped stick and testing it with a nucleic acid amplification test (NAAT), like a [PCR test](https:\/\/my.clevelandclinic.org\/health\/diagnostics\/21462-covid-19-and-pcr-testing). You can also test at home with a [rapid antigen test](https:\/\/health.clevelandclinic.org\/how-to-do-an-at-home-covid-test).\n\n## Management and Treatment\n### How is COVID treated?\nCOVID can be treated with antiviral medications. These include [nirmatrelvir\/ritonavir](https:\/\/my.clevelandclinic.org\/health\/drugs\/23671-nirmatrelvir-ritonavir-tablets) (Paxlovid®), [remdesivir](https:\/\/my.clevelandclinic.org\/health\/drugs\/23851-remdesivir) (Veklury®) and [molnupiravir](https:\/\/my.clevelandclinic.org\/health\/drugs\/23771-molnupiravir-oral-capsules) (Lagevrio™). When taken within the first five days, antivirals can help you feel better and reduce your risk of severe illness and long COVID.  \n  \nIf you’re severely ill and hospitalized, your healthcare provider might treat you with:\n\n- [Monoclonal antibody](https:\/\/my.clevelandclinic.org\/health\/treatments\/22246-monoclonal-antibodies) treatment\n- [Supplemental oxygen](https:\/\/my.clevelandclinic.org\/health\/treatments\/23194-oxygen-therapy)\n- [Corticosteroids](https:\/\/my.clevelandclinic.org\/health\/treatments\/corticosteroids-glucocorticoids)\n- [Mechanical ventilation](https:\/\/my.clevelandclinic.org\/health\/treatments\/15368-mechanical-ventilation)\n#### Recovery time\nMany people recover from symptoms like congestion, sore throat and cough in about two weeks. But tiredness, shortness of breath and other symptoms can linger for weeks or even months afterwards.\n\n#### How long are you contagious with COVID?\nYou can be contagious with COVID from a couple of days before your symptoms start to about eight to 10 days after.\n\n### When should I see my healthcare provider?\nIf you have symptoms of COVID, talk to your provider early to see if you should take an antiviral. See your provider if your symptoms last longer than four weeks, especially if they aren’t improving.\n\n#### When should I go to the ER?\nCall 911 or get to an emergency room if you experience:\n\nAdvertisement\n\n- Difficulty breathing\n- [Chest pain](https:\/\/my.clevelandclinic.org\/health\/symptoms\/21209-chest-pain)\n- Severe leg pain, warmth or other signs of deep vein thrombosis\n- Blue or gray skin, lips or nails ([cyanosis](https:\/\/my.clevelandclinic.org\/health\/diseases\/24297-cyanosis))\n- [Confusion](https:\/\/my.clevelandclinic.org\/health\/symptoms\/25206-confusion)\n\nCare at Cleveland Clinic\n\n[Get Cold, Flu & COVID-19 Care](https:\/\/my.clevelandclinic.org\/services\/cold-flu-covid-19-care)\n\n[Find a Walk-in Location Near You](https:\/\/my.clevelandclinic.org\/services\/cold-flu-covid-19-care#locations-panel)\n\n## Outlook \/ Prognosis\n### What can I expect if I have COVID?\nThe outlook for COVID is different for everyone. Some people have only mild symptoms. Some get very sick and need to be hospitalized. Sometimes, your symptoms seem to get better and then get much worse. Always seek emergency medical attention for severe symptoms, no matter when they happen.\n\n### Is there anything I can do to feel better?\nOver-the-counter medications can help ease some of the symptoms of COVID, though they won’t treat the virus itself. If your child has COVID, talk to their pediatrician before giving them medications to make sure they’re safe to take.\n\n## Prevention\n### Can COVID be prevented?\nMaking sure you’re up to date with a current [COVID vaccine](https:\/\/my.clevelandclinic.org\/health\/procedures\/covid-vaccine) is the best way to reduce your risk of getting sick with COVID — and reduce your risk of severe illness [if you do get sick](https:\/\/health.clevelandclinic.org\/breakthrough-covid-cases). You’re also less likely to get long COVID if you’re vaccinated.\n\nYou can also reduce your risk by washing your hands frequently and wearing a mask when COVID is spreading. Be courteous and [avoid being around others](https:\/\/health.clevelandclinic.org\/does-someone-in-your-home-have-covid-19-heres-what-to-do) if you’re sick or might’ve been exposed to someone who’s sick.\n\nIf you have a compromised immune system, the monoclonal antibody medication pemivibart (Pemgarda™) might be an option. A provider gives it to you in an IV (through your vein) to reduce your risk of getting COVID (pre-exposure prophylaxis).\n\nAdvertisement\n\n## Additional Common Questions\n### How long should I quarantine after a positive COVID test with symptoms?\nAccording to current CDC recommendations in the U.S., you should self-isolate until you’ve met both of the following criteria:\n\n- It’s been five days since your symptoms first appeared and your symptoms are improving.\n- You haven’t had a fever for 24 hours and you haven’t used fever-lowering medications during this time.\n### A note from Cleveland Clinic\nThe beginnings of the COVID pandemic might seem far away at this point. Remembering things like elbow bumps and virtual birthday parties might even seem quaint. But COVID had a devastating effect on the world — and it seems to be here to stay. Vaccinations and antiviral medications can help reduce your risk of severe illness.\n\nAdvertisement\n\n[![Cleveland Clinic logo](https:\/\/my.clevelandclinic.org\/_next\/static\/media\/logo-ccf.1e52a22b.svg?w=3840&q=75)](https:\/\/my.clevelandclinic.org\/)[![Cleveland Clinic icon](https:\/\/my.clevelandclinic.org\/_next\/static\/media\/CCFLogo.000428c6.svg?w=3840&q=75)](https:\/\/my.clevelandclinic.org\/)\n\n[![Health Essentials logo](https:\/\/my.clevelandclinic.org\/_next\/static\/media\/HealthEssentials.b811bb06.svg?w=3840&q=75)](https:\/\/health.clevelandclinic.org\/)\n\n![Subscription icon](https:\/\/assets.clevelandclinic.org\/transform\/482db8cd-aa1e-45b5-a2a4-cf6aa5e5d2d4\/Health-Essentials?w=256&q=75)\n\n## Better health starts here\nSign up for our Health Essentials emails for expert guidance on nutrition, fitness, sleep, skin care and more.\n\n[Example email](https:\/\/assets.clevelandclinic.org\/transform\/2ff943a2-abb1-4a1c-8ede-f8848703e789\/HealthEssentials-SampleEmail-2026)[Sign up](https:\/\/my.clevelandclinic.org\/health-essentials-sign-up)\n\n[Sign up](https:\/\/my.clevelandclinic.org\/health-essentials-sign-up)[Example email](https:\/\/assets.clevelandclinic.org\/transform\/2ff943a2-abb1-4a1c-8ede-f8848703e789\/HealthEssentials-SampleEmail-2026)\n\n### Experts You Can Trust\nMedically Reviewed.\n\nLast updated on 02\/28\/2025.\n\nLearn more about the [Health Library](https:\/\/my.clevelandclinic.org\/health\/about) and our [editorial process](https:\/\/my.clevelandclinic.org\/about\/website\/editorial-policy).\n\n### References\nCleveland Clinic’s health articles are based on evidence-backed information and review by medical professionals to ensure accuracy, reliability and up-to-date clinical standards.\n#### View Sources\n\n### Experts You Can Trust\nMedically Reviewed.\n\nLast updated on 02\/28\/2025.\n\n### References\nCleveland Clinic’s health articles are based on evidence-backed information and review by medical professionals to ensure accuracy, reliability and up-to-date clinical standards.\n\n- Bock A.

View image online (https://my.clevelandclinic.org/-/scassets/images/org/health/articles/covid-symptoms) COVID symptoms can range from mild and cold-like to severe and life-threatening. COVID-19 is a respiratory illness caused by the SARS-CoV-2 [virus](https://my.clevelandclinic.org/health/body/24861-virus), a type of coronavirus. Symptoms range from mild and cold-like to severe and life-threatening. Advertisement Cleveland Clinic is a non-profit academic medical center. Advertising on our site helps support our mission. We do not endorse non-Cleveland Clinic products or services. [Policy](https://health.clevelandclinic.org/advertising) Coronaviruses have typically caused [common colds](https://my.clevelandclinic.org/health/diseases/12342-common-cold). But in 2019, a new coronavirus, SARS-CoV-2, started infecting humans and causing severe illness. At the peak of the pandemic — when COVID was spreading around the world — [tens of thousands](https://pubmed.ncbi.nlm.nih.gov/35452402/) of people were hospitalized every day in the U.S. alone. Millions of people have died. Medical professionals’ understanding has grown a lot since the start of the pandemic. The virus itself keeps changing — we’ve gone through variants alpha, beta, gamma, delta and now omicron. Scientists have developed treatments and [vaccines](https://my.clevelandclinic.org/health/treatments/24135-vaccines) that have reduced the number of people ending up in the hospital. But COVID isn’t “over.” It can still make you severely ill, cause symptoms that last months or years, and be fatal. ## Symptoms and Causes ### Symptoms of COVID-19 COVID symptoms include: - [Fever](https://my.clevelandclinic.org/health/symptoms/10880-fever) - [Sore throat](https://my.clevelandclinic.org/health/diseases/8274-sore-throat-pharyngitis) - [Headache](https://my.clevelandclinic.org/health/diseases/9639-headaches) - Tiredness ([fatigue](https://my.clevelandclinic.org/health/symptoms/21206-fatigue)) - [Body aches](https://my.clevelandclinic.org/health/symptoms/myalgia-muscle-pain) - [Chills](https://my.clevelandclinic.org/health/symptoms/21476-chills) - [Stuffy](https://my.clevelandclinic.org/health/diseases/17980-nasal-congestion) or [runny nose](https://my.clevelandclinic.org/health/symptoms/17660-runny-nose) - [Cough](https://my.clevelandclinic.org/health/symptoms/17755-cough) - [Shortness of breath](https://my.clevelandclinic.org/health/symptoms/16942-dyspnea) - [Loss of](https://my.clevelandclinic.org/health/symptoms/16708-loss-of-taste-and-smell) or [altered](https://my.clevelandclinic.org/health/diseases/22047-dysgeusia#:~:text=Dysgeusia%20is%20a%20taste%20disorder,medication%20or%20poor%20oral%20hygiene.) sense of smell and taste - Difficulty thinking and focusing ([brain fog](https://my.clevelandclinic.org/health/symptoms/brain-fog)) - Digestive symptoms, like [diarrhea](https://my.clevelandclinic.org/health/diseases/4108-diarrhea), [nausea](https://my.clevelandclinic.org/health/symptoms/nausea) and [vomiting](https://my.clevelandclinic.org/health/symptoms/vomiting) Some people have no symptoms but can still spread the virus. ### COVID causes SARS-CoV-2 virus causes COVID. It’s a type of coronavirus, a group of viruses that also cause common colds. But this isn’t the first time a coronavirus has caused serious illness. [SARS](https://my.clevelandclinic.org/health/diseases/10856-severe-acute-respiratory-syndrome-sars), a severe respiratory disease that spread between 2002 and 2004, was also a coronavirus. Advertisement COVID spreads through respiratory droplets. This means you can get it from coughing, sneezing and talking. You might also get it from touching contaminated objects and surfaces. #### Risk factors You’re at an increased risk of being hospitalized with COVID-19 if you: - Are over 65 - Are [pregnant](https://my.clevelandclinic.org/health/articles/pregnancy) - [Smoke](https://my.clevelandclinic.org/health/articles/17488-smoking) or used to smoke - Have received a solid organ or [stem cell transplant](https://my.clevelandclinic.org/health/treatments/22567-stem-cell-transplants) You’re also at an increased risk if you have: - A blood disorder such as [sickle cell disease](https://my.clevelandclinic.org/health/diseases/12100-sickle-cell-disease) or [thalassemia](https://my.clevelandclinic.org/health/diseases/14508-thalassemias) - Cancer - Cerebrovascular disease, such as [stroke](https://my.clevelandclinic.org/health/diseases/5601-stroke) - Chronic conditions that affect your lungs, kidneys, liver or heart - Congenital conditions like [cerebral palsy](https://my.clevelandclinic.org/health/diseases/8717-cerebral-palsy) or [Down syndrome](https://my.clevelandclinic.org/health/diseases/17818-down-syndrome) - Diabetes (Type 1 or Type 2) - [HIV/AIDS](https://my.clevelandclinic.org/health/diseases/4251-hiv-aids) or a [compromised (weakened) immune system](https://my.clevelandclinic.org/health/diseases/immunocompromised) - Mental health conditions, such as [depression](https://my.clevelandclinic.org/health/diseases/9290-depression) or [schizophrenia](https://my.clevelandclinic.org/health/diseases/4568-schizophrenia) spectrum disorders - Neurological conditions, like [dementia](https://my.clevelandclinic.org/health/diseases/9170-dementia) or [Alzheimer’s disease](https://my.clevelandclinic.org/health/diseases/9164-alzheimers-disease) - [Obesity](https://my.clevelandclinic.org/health/diseases/11209-weight-control-and-obesity) - [Substance use disorders](https://my.clevelandclinic.org/health/diseases/16652-drug-addiction-substance-use-disorder-sud) such as alcohol, opioid or cocaine use disorder - [Tuberculosis](https://my.clevelandclinic.org/health/diseases/11301-tuberculosis) ### Complications of COVID COVID can cause serious complications, even if you don’t feel very sick. These include: - [Pneumonia](https://my.clevelandclinic.org/health/diseases/24002-covid-pneumonia) - [Acute respiratory distress syndrome](https://my.clevelandclinic.org/health/diseases/15283-acute-respiratory-distress-syndrome-ards) (ARDS) - [Blood clots](https://my.clevelandclinic.org/health/body/17675-blood-clots), including [pulmonary embolism](https://my.clevelandclinic.org/health/diseases/17400-pulmonary-embolism) (PE) or [deep vein thrombosis](https://my.clevelandclinic.org/health/diseases/16911-deep-vein-thrombosis-dvt) (DVT) - Heart inflammation ([myocarditis](https://my.clevelandclinic.org/health/diseases/22129-myocarditis)/[pericarditis](https://my.clevelandclinic.org/health/diseases/17353-pericarditis)) - [Cardiac arrest](https://my.clevelandclinic.org/health/diseases/21736-cardiac-arrest) - [Multisystem inflammatory syndrome in children](https://my.clevelandclinic.org/health/diseases/24592-multisystem-inflammatory-syndrome-in-children) (MIS-C) - [Long COVID](https://my.clevelandclinic.org/health/diseases/25111-long-covid), a condition where pain, extreme fatigue and other symptoms last for months or years after a COVID infection ## Diagnosis and Tests ### How doctors diagnose COVID Healthcare providers diagnose COVID by swabbing your nose with a soft-tipped stick and testing it with a nucleic acid amplification test (NAAT), like a [PCR test](https://my.clevelandclinic.org/health/diagnostics/21462-covid-19-and-pcr-testing). You can also test at home with a [rapid antigen test](https://health.clevelandclinic.org/how-to-do-an-at-home-covid-test). ## Management and Treatment ### How is COVID treated? COVID can be treated with antiviral medications. These include [nirmatrelvir/ritonavir](https://my.clevelandclinic.org/health/drugs/23671-nirmatrelvir-ritonavir-tablets) (Paxlovid®), [remdesivir](https://my.clevelandclinic.org/health/drugs/23851-remdesivir) (Veklury®) and [molnupiravir](https://my.clevelandclinic.org/health/drugs/23771-molnupiravir-oral-capsules) (Lagevrio™). When taken within the first five days, antivirals can help you feel better and reduce your risk of severe illness and long COVID. If you’re severely ill and hospitalized, your healthcare provider might treat you with: - [Monoclonal antibody](https://my.clevelandclinic.org/health/treatments/22246-monoclonal-antibodies) treatment - [Supplemental oxygen](https://my.clevelandclinic.org/health/treatments/23194-oxygen-therapy) - [Corticosteroids](https://my.clevelandclinic.org/health/treatments/corticosteroids-glucocorticoids) - [Mechanical ventilation](https://my.clevelandclinic.org/health/treatments/15368-mechanical-ventilation) #### Recovery time Many people recover from symptoms like congestion, sore throat and cough in about two weeks. But tiredness, shortness of breath and other symptoms can linger for weeks or even months afterwards. #### How long are you contagious with COVID? You can be contagious with COVID from a couple of days before your symptoms start to about eight to 10 days after. ### When should I see my healthcare provider? If you have symptoms of COVID, talk to your provider early to see if you should take an antiviral. See your provider if your symptoms last longer than four weeks, especially if they aren’t improving. #### When should I go to the ER? Call 911 or get to an emergency room if you experience: Advertisement - Difficulty breathing - [Chest pain](https://my.clevelandclinic.org/health/symptoms/21209-chest-pain) - Severe leg pain, warmth or other signs of deep vein thrombosis - Blue or gray skin, lips or nails ([cyanosis](https://my.clevelandclinic.org/health/diseases/24297-cyanosis)) - [Confusion](https://my.clevelandclinic.org/health/symptoms/25206-confusion) Care at Cleveland Clinic [Get Cold, Flu & COVID-19 Care](https://my.clevelandclinic.org/services/cold-flu-covid-19-care) [Find a Walk-in Location Near You](https://my.clevelandclinic.org/services/cold-flu-covid-19-care#locations-panel) ## Outlook / Prognosis ### What can I expect if I have COVID? The outlook for COVID is different for everyone. Some people have only mild symptoms. Some get very sick and need to be hospitalized. Sometimes, your symptoms seem to get better and then get much worse. Always seek emergency medical attention for severe symptoms, no matter when they happen. ### Is there anything I can do to feel better? Over-the-counter medications can help ease some of the symptoms of COVID, though they won’t treat the virus itself. If your child has COVID, talk to their pediatrician before giving them medications to make sure they’re safe to take. ## Prevention ### Can COVID be prevented? Making sure you’re up to date with a current [COVID vaccine](https://my.clevelandclinic.org/health/procedures/covid-vaccine) is the best way to reduce your risk of getting sick with COVID — and reduce your risk of severe illness [if you do get sick](https://health.clevelandclinic.org/breakthrough-covid-cases). You’re also less likely to get long COVID if you’re vaccinated. You can also reduce your risk by washing your hands frequently and wearing a mask when COVID is spreading. Be courteous and [avoid being around others](https://health.clevelandclinic.org/does-someone-in-your-home-have-covid-19-heres-what-to-do) if you’re sick or might’ve been exposed to someone who’s sick. If you have a compromised immune system, the monoclonal antibody medication pemivibart (Pemgarda™) might be an option. A provider gives it to you in an IV (through your vein) to reduce your risk of getting COVID (pre-exposure prophylaxis).

According to current CDC recommendations in the U.S., you should self-isolate until you’ve met both of the following criteria: - It’s been five days since your symptoms first appeared and your symptoms are improving. - You haven’t had a fever for 24 hours and you haven’t used fever-lowering medications during this time. ### A note from Cleveland Clinic The beginnings of the COVID pandemic might seem far away at this point. Remembering things like elbow bumps and virtual birthday parties might even seem quaint. But COVID had a devastating effect on the world — and it seems to be here to stay. Vaccinations and antiviral medications can help reduce your risk of severe illness.
