Symptoms may change with new COVID-19 variants and can vary depending on vaccination status. Possible symptoms include:\nFever or chills\nCough\nShortness of breath or difficulty breathing\nSore throat\nCongestion or runny nose\nNew loss of taste or smell\nFatigue\nMuscle or body aches\nHeadache\nNausea or vomiting\nDiarrhea\nCDC will continue to update this list as we learn more about COVID-19.\nFeeling Sick?\nStay home and away from others\n(including people you live with who are not sick) if you have symptoms that aren't better explained by another cause.\nSeek health care promptly for testing and\/or treatment if you have\nrisk factors for severe illness\n;\ntreatment\nmay help lower your risk of severe illness.\nWhen to seek emergency help\nLook for emergency warning signs* for COVID 19:\nTrouble breathing\nPersistent pain or pressure in the chest\nNew confusion\nInability to wake or stay awake\nDepending on skin tone, lips, nail beds and skin may appear pale, gray, or blue.\nIf someone is showing any of these signs, call 911 or call ahead to your local emergency facility. Notify the operator that you are seeking care for someone who has or may have COVID-19.\n*This list does not include all possible symptoms. Please call your medical provider for any other symptoms that are severe or concerning to you.\nDifference between flu and COVID-19\nInfluenza (Flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a coronavirus named SARS-CoV-2, and flu is caused by infection with one of the influenza viruses. You cannot tell the difference between flu and COVID-19 by symptoms alone because some of the symptoms are the same.\nSome nucleic acid amplification tests (NAATs), including PCR tests, can differentiate between flu and COVID-19 at the same time. If one of these tests is not available, many\ntesting locations\nprovide flu and COVID-19 tests separately.\nMarch 10, 2025","attrs_markdown":"[Skip directly to site content](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#content) [Skip directly to search](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#cdc-search__input) [Skip directly to On This Page](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#first-on-this-page)\n\n![](https:\/\/www.cdc.gov\/TemplatePackage\/5.0\/img\/uswds\/us_flag_small.png) An official website of the United States government\n\n[Here's how you know](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#gov-notice)\n\n![](https:\/\/www.cdc.gov\/TemplatePackage\/5.0\/img\/uswds\/icon-dot-gov.svg)\n\n**Official websites use .gov**\n\nA **.gov** website belongs to an official government organization in the United States.\n\n![](https:\/\/www.cdc.gov\/TemplatePackage\/5.0\/img\/uswds\/icon-https.svg)\n\n**Secure .gov websites use HTTPS**\n\nA **lock** (  ) or **https:\/\/** means you've safely connected to the .gov website.

[Español](https:\/\/www.cdc.gov\/covid\/es\/signs-symptoms\/sintomas-del-covid-19.html)\n\nFor Everyone\n# Symptoms of COVID-19\n## Key points\n- People with COVID-19 have a wide range of symptoms ranging from mild symptoms to severe illness.\n- Symptoms may appear 2-14 days after exposure to the virus.\n- Symptoms may start as mild, and some people will progress to more severe symptoms.\n\n![Health care provider taking a patient's temperature.](https:\/\/www.cdc.gov\/covid\/media\/images\/2024\/07\/gettyimages-1216034366-612x612-1.jpg)\n\n## Signs and Symptoms\nThe following list does not include all possible symptoms. Symptoms may change with new COVID-19 variants and can vary depending on vaccination status. Possible symptoms include:\n\n- Fever or chills\n- Cough\n- Shortness of breath or difficulty breathing\n- Sore throat\n- Congestion or runny nose\n- New loss of taste or smell\n- Fatigue\n- Muscle or body aches\n- Headache\n- Nausea or vomiting\n- Diarrhea\n\nCDC will continue to update this list as we learn more about COVID-19.\n\n### Feeling Sick?\n[Stay home and away from others](https:\/\/www.cdc.gov\/respiratory-viruses\/prevention\/precautions-when-sick.html) (including people you live with who are not sick) if you have symptoms that aren't better explained by another cause.\n\nSeek health care promptly for testing and\/or treatment if you have [risk factors for severe illness](https:\/\/www.cdc.gov\/respiratory-viruses\/risk-factors\/index.html); [treatment](https:\/\/www.cdc.gov\/covid\/treatment\/index.html) may help lower your risk of severe illness.\n\n## When to seek emergency help\nLook for emergency warning signs\\* for COVID 19:\n\n- Trouble breathing\n- Persistent pain or pressure in the chest\n- New confusion\n- Inability to wake or stay awake\n- Depending on skin tone, lips, nail beds and skin may appear pale, gray, or blue.\n\nIf someone is showing any of these signs, call 911 or call ahead to your local emergency facility. Notify the operator that you are seeking care for someone who has or may have COVID-19.\n\n*\\*This list does not include all possible symptoms. Please call your medical provider for any other symptoms that are severe or concerning to you.*\n\n## Difference between flu and COVID-19\nInfluenza (Flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a coronavirus named SARS-CoV-2, and flu is caused by infection with one of the influenza viruses. You cannot tell the difference between flu and COVID-19 by symptoms alone because some of the symptoms are the same.\n\nSome nucleic acid amplification tests (NAATs), including PCR tests, can differentiate between flu and COVID-19 at the same time. If one of these tests is not available, many [testing locations](https:\/\/www.cdc.gov\/covid\/testing\/index.html) provide flu and COVID-19 tests separately.\n\n**Keep Reading:** [Similarities and Differences between Flu and COVID-19](https:\/\/www.cdc.gov\/flu\/symptoms\/flu-vs-covid19.htm)\n\n## Resources\n### Videos\n[Symptoms of Coronavirus Disease 2019 (youtube.com)](https:\/\/www.youtube.com\/watch?v=F70BzSFAZfw)\n\n## On This Page\n- [Signs and Symptoms](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#cdc_symptoms_section_1-signs-and-symptoms)\n- [When to seek emergency help](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#cdc_symptoms_seek_help-when-to-seek-emergency-help)\n- [Difference between flu and COVID-19](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#cdc_symptoms_compare-difference-between-flu-and-covid-19)\n- [Resources](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#cdc_symptoms_res-resources)\n\n## Related Pages\n- [About COVID-19](https:\/\/www.cdc.gov\/covid\/about\/index.html)\n- [People with Certain Medical Conditions and COVID-19](https:\/\/www.cdc.gov\/covid\/risk-factors\/index.html)\n- [COVID-19 Vaccines](https:\/\/www.cdc.gov\/covid\/vaccines\/index.html)\n- [Testing](https:\/\/www.cdc.gov\/covid\/testing\/index.html)\n- [Treatment](https:\/\/www.cdc.gov\/covid\/treatment\/index.html)\n\n[View All Covid](https:\/\/www.cdc.gov\/covid\/site.html#gen)\n\n[People with Certain Medical Conditions and COVID-19](https:\/\/www.cdc.gov\/covid\/risk-factors\/index.html)\n\nMarch 10, 2025\n\n[Sources](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#content-sources) [Print](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#print) [Share](https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html#share)\n\n[Facebook](https:\/\/www.facebook.com\/sharer\/sharer.php?u=https%3A%2F%2Fwww.cdc.gov%2Fcovid%2Fsigns-symptoms%2Findex.html \"Share to Facebook\")   [LinkedIn](https:\/\/www.linkedin.com\/shareArticle?url=https%3A%2F%2Fwww.cdc.gov%2Fcovid%2Fsigns-symptoms%2Findex.html&title=Symptoms%20of%20COVID-19 \"Share to LinkedIn\")   [Twitter](http:\/\/twitter.com\/share?url=https%3A%2F%2Fwww.cdc.gov%2Fcovid%2Fsigns-symptoms%2Findex.html&text=Symptoms%20of%20COVID-19 \"Share to Twitter\")   [Syndicate](https:\/\/tools.cdc.gov\/medialibrary\/index.aspx#\/sharecontent\/https:\/\/https:\/\/www.cdc.gov\/covid\/signs-symptoms\/index.html \"Embed this Page\")\n\nContent Source:\n\n[National Center for Immunization and Respiratory Diseases](https:\/\/www.cdc.gov\/ncird\/index.html); [Coronavirus and Other Respiratory Viruses Division](https:\/\/www.cdc.gov\/ncird\/divisions-offices\/index.html)\n\n## Related Pages\n- [About COVID-19](https:\/\/www.cdc.gov\/covid\/about\/index.html)\n- [People with Certain Medical Conditions and COVID-19](https:\/\/www.cdc.gov\/covid\/risk-factors\/index.html)\n- [COVID-19 Vaccines](https:\/\/www.cdc.gov\/covid\/vaccines\/index.html)\n- [Testing](https:\/\/www.cdc.gov\/covid\/testing\/index.html)\n- [Treatment](https:\/\/www.cdc.gov\/covid\/treatment\/index.html)\n\n[View All Covid](https:\/\/www.cdc.gov\/covid\/site.html#gen)\n\nBack to Top\n\n## [Covid](https:\/\/www.cdc.gov\/covid\/index.html)\nCOVID-19 (coronavirus disease 2019) is a disease caused by a virus named SARS-CoV-2.

[Español](https://www.cdc.gov/covid/es/signs-symptoms/sintomas-del-covid-19.html) For Everyone # Symptoms of COVID-19 ## Key points - People with COVID-19 have a wide range of symptoms ranging from mild symptoms to severe illness. - Symptoms may appear 2-14 days after exposure to the virus. - Symptoms may start as mild, and some people will progress to more severe symptoms. ![Health care provider taking a patient's temperature.](https://www.cdc.gov/covid/media/images/2024/07/gettyimages-1216034366-612x612-1.jpg) ## Signs and Symptoms The following list does not include all possible symptoms. Symptoms may change with new COVID-19 variants and can vary depending on vaccination status. Possible symptoms include: - Fever or chills - Cough - Shortness of breath or difficulty breathing - Sore throat - Congestion or runny nose - New loss of taste or smell - Fatigue - Muscle or body aches - Headache - Nausea or vomiting - Diarrhea CDC will continue to update this list as we learn more about COVID-19. ### Feeling Sick? [Stay home and away from others](https://www.cdc.gov/respiratory-viruses/prevention/precautions-when-sick.html) (including people you live with who are not sick) if you have symptoms that aren't better explained by another cause. Seek health care promptly for testing and/or treatment if you have [risk factors for severe illness](https://www.cdc.gov/respiratory-viruses/risk-factors/index.html); [treatment](https://www.cdc.gov/covid/treatment/index.html) may help lower your risk of severe illness. ## When to seek emergency help Look for emergency warning signs\* for COVID 19: - Trouble breathing - Persistent pain or pressure in the chest - New confusion - Inability to wake or stay awake - Depending on skin tone, lips, nail beds and skin may appear pale, gray, or blue. If someone is showing any of these signs, call 911 or call ahead to your local emergency facility. Notify the operator that you are seeking care for someone who has or may have COVID-19. \This list does not include all possible symptoms. Please call your medical provider for any other symptoms that are severe or concerning to you.* ## Difference between flu and COVID-19 Influenza (Flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a coronavirus named SARS-CoV-2, and flu is caused by infection with one of the influenza viruses. You cannot tell the difference between flu and COVID-19 by symptoms alone because some of the symptoms are the same. Some nucleic acid amplification tests (NAATs), including PCR tests, can differentiate between flu and COVID-19 at the same time. If one of these tests is not available, many [testing locations](https://www.cdc.gov/covid/testing/index.html) provide flu and COVID-19 tests separately.

Readable Markdown	- People with COVID-19 have a wide range of symptoms ranging from mild symptoms to severe illness. - Symptoms may appear 2-14 days after exposure to the virus. - Symptoms may start as mild, and some people will progress to more severe symptoms. ![Health care provider taking a patient's temperature.](https://www.cdc.gov/covid/media/images/2024/07/gettyimages-1216034366-612x612-1.jpg) ## Signs and Symptoms The following list does not include all possible symptoms. Symptoms may change with new COVID-19 variants and can vary depending on vaccination status. Possible symptoms include: - Fever or chills - Cough - Shortness of breath or difficulty breathing - Sore throat - Congestion or runny nose - New loss of taste or smell - Fatigue - Muscle or body aches - Headache - Nausea or vomiting - Diarrhea CDC will continue to update this list as we learn more about COVID-19. ### Feeling Sick? [Stay home and away from others](https://www.cdc.gov/respiratory-viruses/prevention/precautions-when-sick.html) (including people you live with who are not sick) if you have symptoms that aren't better explained by another cause. Seek health care promptly for testing and/or treatment if you have [risk factors for severe illness](https://www.cdc.gov/respiratory-viruses/risk-factors/index.html); [treatment](https://www.cdc.gov/covid/treatment/index.html) may help lower your risk of severe illness. ## When to seek emergency help Look for emergency warning signs\* for COVID 19: - Trouble breathing - Persistent pain or pressure in the chest - New confusion - Inability to wake or stay awake - Depending on skin tone, lips, nail beds and skin may appear pale, gray, or blue. If someone is showing any of these signs, call 911 or call ahead to your local emergency facility. Notify the operator that you are seeking care for someone who has or may have COVID-19. \This list does not include all possible symptoms. Please call your medical provider for any other symptoms that are severe or concerning to you.* ## Difference between flu and COVID-19 Influenza (Flu) and COVID-19 are both contagious respiratory illnesses, but they are caused by different viruses. COVID-19 is caused by infection with a coronavirus named SARS-CoV-2, and flu is caused by infection with one of the influenza viruses. You cannot tell the difference between flu and COVID-19 by symptoms alone because some of the symptoms are the same. Some nucleic acid amplification tests (NAATs), including PCR tests, can differentiate between flu and COVID-19 at the same time. If one of these tests is not available, many [testing locations](https://www.cdc.gov/covid/testing/index.html) provide flu and COVID-19 tests separately. March 10, 2025
